William Radford
–
William Radford was a rear admiral of the United States Navy who served during the Mexican-American War and the American Civil War, in which he remained loyal to the Union, despite his Virginia birth. Radford commanded the Ironclad Division in the attacks on Fort Fisher to assert Union control of Cape Fear, on December 23,1806, John Radford married Harriet Kennerly in Fincastle, Virginia at Santillane, the estate of her uncle George Hancock. In attendance at the wedding was William Clark direct from the Corps of Discovery exploration, there is a discrepancy about Williams birth-date, with some references giving it as March 1,1808 but family records and the U. S. Federal Census forms support the 1809 date. Widow Harriet moved her three children to Saint Louis, Missouri to join her brothers and first cousin Judith Julia Hancock Clark, the Radfords resided with her brother James Kennerly. Julia Clark succumbed June 27,1820, widower William Clark married Harriet November 28,1821 in Saint Louis, adopted the Radford children and added three children to their combined family, Harriet Clark. He asked stepfather William Clark for a recommendation to the U. S. Navy, Clark sent a personal request to President John Quincy Adams. William Clarks diaries mention Radford accompanying him in 1824 from Saint Louis to Washington, before returning home, they diverted to New York City and observed the heros welcome for Marquis de Lafayette. Radford embarked upon another Clark trip to Washington, D. C. in the fall of 1828, an excursion in early January 1829 to visit stepbrother Meriwether Lewis Clark at West Point was abandoned due to ice floes on the Hudson River. After witnessing the inauguration of President Andrew Jackson they returned to Saint Louis, Radford was accepted March 1,1825 into the United States Navy as a midshipman. He reported 1 August 1825 to Captain Charles Morris for duty aboard Brandywine at Washington Navy Yard. While the ship carried only 8 to 10 midshipmen, President Adams appointed a total of 24, at least one from each state. Radford represented the state of Missouri, Lafayette was delivered to Le Havre on October 9,1825. From there Brandywine was attached to the Mediterranean Squadron under Commodore John Rodgers, upon the departure of Brandywine February 25,1826, Radford transferred to Constitution to remain in the Mediterranean monitoring the Greek War of Independence and coup against the Janissaries. Rodgers was succeeded by Commodore William Crane March 30,1827, Constitution, in need of major repairs, was recalled to Boston Navy Yard arriving on July 4,1828. Radford returned to Saint Louis and received orders August 10,1829, Radford was promoted to passed midshipman June 4,1831 and reported for duty in Philadelphia Naval Shipyard. In September 1831, he requested a leave and was with his mother Harriet when she died December 25,1831. He was then entered into a due to the general stagnation of naval affairs. Radford was assigned to the receiving ship Sea Gull at Philadelphia in February 1834, then in June 1834 he returned to the Mediterranean Squadron aboard John Adams as the acting Master

Federal Shipbuilding and Drydock Company
–
The Federal Shipbuilding and Drydock Company was a United States shipyard, active from 1917 to 1948. It was founded during World War I to build ships for the United States Shipping Board, during World War II, it built ships as part of the U. S. The shipyard site is now part of River Terminal, a distribution facility that is partially a foreign trade zone. Federal built numerous destroyers, destroyer escorts and a handful of light cruisers as well as merchant ships during, around 570 vessels were contracted for construction by Federal SB&DD Company with about 100 not delivered fully completed due to the end of the World War II. Federal also had a yard at Port Newark during World War II that built destroyers, Federal Shipbuilding and Dry Dock Company was founded July 24,1917 as a subsidiary of United States Steel Corporation to supply ships for the United States Shipping Board during World War I. The site on Kearny Point was first surveyed during the summer of 1917, the shipyard was to consist of everything needed to fully complete a ship from a facility power plant to a wood joining shop. A steel plate mill and boiler shop were to be built as well, $10 million was allocated for construction. The American Bridge Company was contracted to provide 10,000 tons of steel for the structures, gary was president of Federal in August 1917. The ship-ways were completed by the fall of 1917 with keels being laid by November 1917, Federal completed a 9,600 ton ship around six weeks before World War I ended as well as two other ships before the close of 1918. 27 ships were delivered to the Emergency Fleet Corporation in 1919, Federal accounted for 5% of the steel merchant tonnage built in 1919. By June 1921, the Federal yard at Kearny had a 535 by 161.5 feet boiler construction shop to build Scotch marine boilers, exhaust stacks, tanks, uptakes,235 boilers had been constructed from September 1919 to June 1921. Boilers constructed there were mostly 15 feet diameter or larger, at that time,250 men were able to construct three boilers a week with a single 8 hour shift each day. By November 1921, Federal had shipbuilding ways for twelve 15,000 ton vessels and had constructed a 9,000 ton floating dry dock, the dry dock was first used June 23,1921 when Transmarine corps SS Suhulco docked. The Kearny yard was 17 acres with 2,400 feet of frontage on the Hackensack River, a wet basin was located at the southern end with a 100-ton 3-legged jib crane for fitting out new ships. On Sunday night, May 18,1924, a fire destroyed the largest building at the Kearny yard causing an initially estimated $500,000 in damage, other estimates were $1.6 million or as high as several million dollars in damage. Firemen used four mobile cranes to try to extinguish fires in the pattern building, over a thousand workers were idled by the fire. The shipyard had around 5,000 workers at the time and was said to be one of the largest steel plants in the world. Fireboats and numerous firemen from around the area were called in to fight the fire spread rapidly through the wooden structures at the Kearny yard

Fletcher-class destroyer
–
The Fletcher class was a class of destroyers built by the United States during World War II. The class was designed in 1939, as a result of dissatisfaction with the destroyer leader types of the Porter. Some went on to serve during the Korean War and into the Vietnam War, the United States Navy commissioned 175 Fletcher-class destroyers between 1942 and 1944, more than any other destroyer class, and the design was generally regarded as highly successful. Fletchers had a speed of 38 knots, and an armament of five 5 guns in single mounts with 1021 torpedoes in two quintuple centerline mounts. The Allen M. Sumner and Gearing classes were Fletcher derivatives, the long-range Fletcher-class ships performed every task asked of a destroyer, from anti-submarine warfare and anti-aircraft warfare to surface action. They could cover the vast distances required by fleet actions in the Pacific, in fact, they served almost exclusively in the Pacific Theater of Operations during World War II, during which they accounted for 29 Imperial Japanese Navy submarines sunk. Three have been preserved as museum ships in the U. S. the Fletcher class was the largest class of destroyer ordered, and was also one of the most successful and popular with the destroyer men themselves. Compared to earlier classes built for the Navy, they carried a significant increase in weapons and other weaponry. Their flush deck construction added structural strength, although it did make them rather cramped, the Fletcher-class was the first generation of destroyers designed after the series of Naval Treaties that had limited ship designs heretofore. The growth in the design was in part to answer a question that always dogged U. S. Navy designs, that being the long range required by operations in the Pacific Ocean. They were also to no less than five 5 in guns and ten deck-mounted torpedo tubes on the centerline. Compared to earlier designs, the Fletchers were large, allowing them to absorb the addition of two 40 mm Bofors quadruple mount AA guns as well as six 20 mm Oerlikon dual AA gun positions. This addition to the AA suite required the deletion of the forward quintuple torpedo mount, Fletchers were also much less top-heavy than previous classes, allowing them to take on additional equipment and weapons without major redesign. They were fortunate in catching American production at the moment, becoming the destroyer design, and only Fletcher-class derivatives. The first design inputs were in the fall of 1939 from questionnaires distributed around design bureaus, the design parameters were the armaments desired of the next destroyer. As such, the questions were of how many guns, torpedoes, also asked was at what point would the design grow large enough to become a torpedo target instead of a torpedo delivery system. As with other previous U. S. flush deck destroyer designs and this was mitigated by deployment to the Pacific Ocean, which is relatively calm. To achieve 38 kn with a 500-ton increase in displacement, shaft horsepower was increased from 50,000 to 60,000 compared to the previous Benson and Gleaves classes

Destroyer
–
Before World War II, destroyers were light vessels with little endurance for unattended ocean operations, typically a number of destroyers and a single destroyer tender operated together. After the war, the advent of the missile allowed destroyers to take on the surface combatant roles previously filled by battleships. This resulted in larger and more powerful guided missile destroyers more capable of independent operation, the emergence and development of the destroyer was related to the invention of the self-propelled torpedo in the 1860s. A navy now had the potential to destroy an enemy battle fleet using steam launches to launch torpedoes. Fast boats armed with torpedoes were built and called torpedo boats, the first seagoing vessel designed to fire the self-propelled Whitehead torpedo was the 33-ton HMS Lightning in 1876. She was armed with two drop collars to launch these weapons, these were replaced in 1879 by a torpedo tube in the bow. By the 1880s, the type had evolved into small ships of 50–100 tons, in response to this new threat, more heavily gunned picket boats called catchers were built which were used to escort the battle fleet at sea. The anti-torpedo boat origin of this type of ship is retained in its name in other languages, including French, Italian, Portuguese, Czech, Greek, Dutch and, up until the Second World War, Polish. At that time, and even into World War I, the function of destroyers was to protect their own battle fleet from enemy torpedo attacks. The task of escorting merchant convoys was still in the future, an important development came with the construction of HMS Swift in 1884, later redesignated TB81. This was a torpedo boat with four 47 mm quick-firing guns. At 23.75 knots, while still not fast enough to engage torpedo boats reliably. Another forerunner of the torpedo boat destroyer was the Japanese torpedo boat Kotaka, designed to Japanese specifications and ordered from the London Yarrow shipyards in 1885, she was transported in parts to Japan, where she was assembled and launched in 1887. The 165-foot long vessel was armed with four 1-pounder quick-firing guns and six torpedo tubes, reached 19 knots, in her trials in 1889, Kotaka demonstrated that she could exceed the role of coastal defense, and was capable of accompanying larger warships on the high seas. The Yarrow shipyards, builder of the parts for the Kotaka, the first vessel designed for the explicit purpose of hunting and destroying torpedo boats was the torpedo gunboat. Essentially very small cruisers, torpedo gunboats were equipped with torpedo tubes, by the end of the 1890s torpedo gunboats were made obsolete by their more successful contemporaries, the torpedo boat destroyers, which were much faster. The first example of this was HMS Rattlesnake, designed by Nathaniel Barnaby in 1885, the gunboat was armed with torpedoes and designed for hunting and destroying smaller torpedo boats. Exactly 200 feet long and 23 feet in beam, she displaced 550 tons, built of steel, Rattlesnake was un-armoured with the exception of a 3⁄4-inch protective deck

5"/38 caliber gun
–
The Mark 12 5/38 caliber gun was a US naval gun. The gun was installed into Single Purpose and Dual Purpose mounts used primarily by the US Navy, the 38 caliber barrel was a mid-length compromise between the previous United States standard 5/51 low-angle gun and 5/25 anti-aircraft gun. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5/25 gun, however, except for the barrel length and the use of semi-fixed ammunition, the 5/38 gun was derived from the 5/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft, the 5/38 entered service on USS Farragut, commissioned in 1934. The base ring mount, which improved the rate of fire, entered service on USS Gridley. Even this advanced system required nearly 100 rounds of ammunition expenditure per aircraft kill, however, the planes were normally killed by shell fragments and not direct hits, barrage fire was used, with many guns firing in the air at the same time. Base ring mounts with integral hoists had a rate of fire of 15 rounds per minute per barrel, however. On pedestal and other mounts lacking integral hoists,12 to 15 rounds per minute was the rate of fire, useful life expectancy was 4600 effective full charges per barrel. The 5/38 cal gun was mounted on a large number of US Navy ships in the World War II era. It was backfitted to many of the World War I-era battleships during their wartime refits and it has left active US Navy service, but it is still on mothballed ships of the United States Navy reserve fleets. It is also used by a number of nations who bought or were given US Navy surplus ships, each mount carries one or two Mk 12 5/38cal Gun Assemblies. The gun assembly shown is used in single mounts, and it is the gun in twin mounts. It is loaded from the left side, the left gun in twin mounts is the mirror image of the right gun, and it is loaded from the right side. The Mk12 gun assembly weighs 3,990 lb, the major Mk12 Gun Assembly characteristics are,158 Semi-automatic During recoil, some of the recoil energy is stored in the counter-recoil system. That stored energy is used during counter-recoil to prepare the gun for the next round, the firing pin is cocked, the breech is opened, the spent powder case is ejected, and the bore is air cleaned. Hand loaded A Projectile-Man and a Powder-Man are stationed at each gun assembly and their job is to move the round, consisting of a projectile and a powder case, from the hoists to the rammer tray, and then start the ram cycle. The hydraulically driven Rammer Spade, called the Power Spade in that picture, is at the back of the Rammer Tray, if the multiple names of the Spade is confusing, look at this footnote. Vertical sliding-wedge breech block The breech block closes the chamber behind the powder case and it also holds the firing pin assembly

Bofors 40 mm gun
–
The Bofors 40 mm gun, often referred to simply as the Bofors gun, is an anti-aircraft/multi-purpose autocannon designed in the 1930s by the Swedish arms manufacturer AB Bofors. It was one of the most popular medium-weight anti-aircraft systems during World War II, a small number of these weapons remain in service to this day, and saw action as late as the Gulf War. In the post-war era the original design was not suitable for action against jet powered aircraft, so Bofors introduced a new model of more power. In spite of sharing almost nothing with the design other than the calibre and the distinctive conical flash hider. Although not as popular as the original L/60 model, the L/70 remains in service to this day, especially as a weapon for light armored vehicles. Bofors itself has been part of BAE Systems AB since March 2005, the Swedish Navy purchased a number of 2 pounder Pom-Poms from Vickers as anti-aircraft guns in 1922. The Navy approached Bofors about the development of a capable replacement. Bofors signed a contract in late 1928, Bofors produced a gun that was a smaller version of a 57 mm semi-automatic gun developed as an anti-torpedo boat weapon in the late 19th century by Finspong. Their first test gun was a re-barreled Nordenfelt version of the Finspong gun, testing of this gun in 1929 demonstrated that a problem existed feeding the weapon in order to maintain a reasonable rate of fire. A mechanism that was enough to handle the stresses of moving the large round was too heavy to move quickly enough to fire rapidly. One attempt to solve this problem used zinc shell cases that burned up when fired and this proved to leave heavy zinc deposits in the barrel, and had to be abandoned. This seemed to be the solution they needed, improving firing rates to a level. During this period Krupp purchased a share of Bofors. Krupp engineers started the process of updating the Bofors factories to use equipment and metallurgy. The prototype was completed and fired in November 1931, and by the middle of the month it was firing strings of two and three rounds. Changes to the mechanism were all that remained, and by the end of the year it was operating at 130 rounds per minute. Continued development was needed to turn it into a suitable for production. Since acceptance trials had been passed the year before, this known as the 40 mm akan M/32

Oerlikon 20 mm cannon
–
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German 20 mm Becker design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II, and many still in use today. During World War I, the German Reinhold Becker developed a 20 mm caliber cannon and this used a 20x70 RB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a scale as an aircraft gun on Luftstreitkräfte warplanes. Because the Treaty of Versailles banned further production of weapons in Germany. SEMAG continued development of the weapon, and in 1924 had produced the SEMAG L, the Oerlikon firm, named after the Zürich suburb where it was based, then acquired all rights to the weapon, plus the manufacturing equipment and the employees of SEMAG. In 1927 the Oerlikon S was added to the product line. This fired a larger cartridge to achieve a muzzle velocity of 830 m/s, at the cost of increased weight. The purpose of development was to improve the performance of the gun as an anti-tank and anti-aircraft weapon. An improved version known as the 1S followed in 1930, three sizes of gun with their different ammunition and barrel length, but very similar mechanisms, continued to be developed in parallel. In 1930 Oerlikon reconsidered the application of its gun in aircraft and introduced the AF and AL, designed to be used in flexible mounts, the 15-round box magazine used by earlier versions of the gun was replaced by drum magazine holding 15 or 30 rounds. In 1935 it made an important step by introducing a series of guns designed to be mounted in or on the wings of fighter aircraft, designated with FF for Flügelfest meaning wing-mounted, these weapons were again available in the three sizes, with designations FF, FFL and FFS. The FF fired a larger cartridge than the AF, 20x72RB. The FF weighed 24 kg and achieved a velocity of 550 to 600 m/s with a rate of fire of 520 rpm. The FFL of 30 kg fired a projectile at a velocity of 675 m/s with a rate of fire of 500 rpm. And the FFS, which weighed 39 kg, delivered a high velocity of 830 m/s at a rate of fire of 470 rpm. Apart from changes to the design of the guns for wing-mounting and remote control, for the FF series drum sizes of 45,60,75 and 100 rounds were available, but most users chose the 60-round drum. The 1930s were a period of global re-armament, and a number of foreign firms took licenses for the Oerlikon family of aircraft cannon

Mark 15 torpedo
–
It was developed by the Naval Torpedo Station Newport concurrently with the Mark 14 and was first deployed in 1938. It replaced the Mark 8 torpedo on surface ships with tubes that could accommodate the longer Mark 15, older destroyers, primarily the Wickes and Clemson classes, continued to use the Mark 8, as did PT boats early in World War II. During the war 9,700 were produced at Newport and at the Naval Ordnance Station Forest Park, one major shared deficiency was the Mark 6 exploder, which usually caused duds. Surface-combatant torpedo attacks very often included confusing splashes from gunnery and aerial bombs, obscuring smoke screens, rarely was a destroyer given a chance for a slow, careful surprise attack. Torpedo results were difficult to estimate under these circumstances, the correction of the Mark 15s problems would depend on the submariners solving theirs. By September 1943, effective methods of deployment were beginning to be distributed to all U. S. destroyers. Anticipating the possibility of war with Japan, the United States planned to move their battleships across the Pacific with the fleet train, Cruisers and destroyers would be responsible for defending this large formation at night. Fleet exercises held during the 1930s revealed the nature of close range engagements during hours of darkness. In 1932, during Fleet Problem XIII, attacking destroyers closed to within 500 yd of USS Saratoga before being detected, Fleet Problem XV in 1934 placed the destroyer screen 7 nmi beyond the battleship formation, but the battleships were unable to differentiate friend from foe at that distance. Screening destroyers were stationed at effective searchlight illumination range,3 nmi. Recognition improved at that distance, but torpedo hit probability increased as evasive maneuvering of the large, United States Navy War Instructions published in 1934 remained in effect through the initial 1942 engagements in the Solomon Islands. The instructions emphasized defense to avoid the attrition objective of Japanese planning, destroyers were to attack at once with guns, but reserve torpedoes for use against capital ships. Searchlight illumination range effectively covered launch positions of United States torpedoes, Japanese ships could remain outside of illumination range, launching torpedoes at American ships revealing their position with gunfire and searchlights.

Depth charge
–
A depth charge is an anti-submarine warfare weapon. It is intended to destroy a submarine by being dropped into the nearby and detonating, subjecting the target to a powerful. Most depth charges use high explosive charges and a set to detonate the charge. Depth charges can be dropped by ships, patrol aircraft, Depth charges were developed during World War I, and were one of the first effective methods of attacking a submarine underwater. They were widely used in World War I and World War II and they remained part of the anti-submarine arsenals of many navies during the Cold War. Depth charges have now largely replaced by anti-submarine homing torpedoes. A depth charge fitted with a warhead is known as a nuclear depth bomb. These were designed to be dropped from a plane or deployed by an anti-submarine missile from a surface ship, or another submarine. All nuclear anti-submarine weapons were withdrawn from service by the United States, the United Kingdom, France, Russia and they were replaced by conventional weapons whose accuracy and range had improved greatly as ASW technology improved. The first attempt to fire charges against submerged targets was with aircraft bombs attached to lanyards which triggered them, a similar idea was a 16 lb guncotton charge in a lanyarded can. Two of these together became known as the depth charge Type A. Problems with the lanyards tangling and failing to function led to the development of a chemical pellet trigger as the Type B and these were effective at a distance of around 20 ft. A1913 Royal Navy Torpedo School report described a device intended for countermining, at Admiral John Jellicoes request, the standard Mark II mine was fitted with a hydrostatic pistol preset for 45 ft firing, to be launched from a stern platform. Weighing 1,150 lb, and effective at 100 ft, the design work was carried out by Herbert Taylor at the RN Torpedo and Mine School, HMS Vernon. The first effective depth charge, the Type D, became available in January 1916 and it was a barrel-like casing containing a high explosive. There were initially two sizes—Type D, with a 300 lb charge for fast ships, and Type D* with a 120 lb charge for ships too slow to leave the area before the more powerful charge detonated. A hydrostatic pistol actuated by water pressure at a pre-selected depth detonated the charge, initial depth settings were 40 or 80 ft. Because production could not keep up with demand, anti-submarine vessels initially carried two depth charges, to be released from a chute at the stern of the ship

Fleet Rehabilitation and Modernization
–
The FRAM program also covered cruisers, aircraft carriers, submarines, amphibious ships, and auxiliaries. The United States Coast Guard also used term in the 1980s for the modernization of its Hamilton-class cutters. The program was started by Admiral Arleigh Burke as a response to estimates that the Soviets would have a force of about 300 modern fast-attack submarines by 1957, Burke oversaw preparation of a report to the House and Senate Appropriations Committees entitled The Aging Fleet. The idea that became FRAM was only one of six recommendations of a committee to address the poor material conditions of ships built during World War II. United States Secretary of the Navy Thomas S. Gates embraced the last recommendation in a meeting with United States Secretary of Defense Neil Hosler McElroy on 11 November 1958, among the destroyers, Gearing and Allen M. Sumner classes would take precedence over the Fletcher and Benson classes. Destroyer conversions relied on experience with Fletcher-class destroyers modernized for transfer to Spain, the first two destroyers began FRAM in Boston, Massachusetts and Long Beach, California shipyards in March 1959. In Navy slang, the destroyers were called FRAM cans, can being a contraction of tin can. Both were armed with the new Mark 44 torpedo, which was carried in torpedo tubes on the ships. ASROC could also launch a nuclear depth charge, there were three different sets of FRAM upgrades. During refitting in the early 1950s, FRAM I Fletcher-class destroyers gave up No,2,3 and 4 5-inch/38 caliber gun mounts. A trainable Mark 15 Hedgehog mount took the place of No.2 gun, connected to a new, all topside 21-inch torpedo tubes were removed and replaced with two tubes mounted in the after deckhouse. One twin 3-inch/50 caliber gun mount was placed aft, atop the after deckhouse, the only Fletcher-class destroyers to receive the FRAM II upgrade were Radford, Jenkins and Nicholas. Ships from the Gearing class were completely torn down and rebuilt from the hull up, including new engines, a larger combat information center. The 21-inch torpedo tubes between the funnels were removed, and the 8-round ASROC launcher placed there instead and this modernization was designed to extend the life of the destroyer by at least eight years. Eventually, all but four Gearings received FRAM I or FRAM II conversions, ships in the Allen M. Summner class received only armament modifications under FRAM II, and not all ships of the class received the FRAM upgrades. Although the rear deck was converted as a flight deck for DASH, the new 12. 75-inch triple torpedo tubes were placed where the older 21-inch ones had been. Typically, all three 5-inch/38 twin mounts were retained, additionally, two new 21-inch torpedo tubes for the Mark 37 ASW homing torpedo and variable depth sonar were added. The converted Allen M. Sumners were designed for five years of service

Hedgehog (weapon)
–
The Hedgehog was a forward-throwing anti-submarine weapon that was used during the Battle of the Atlantic in the Second World War. The device, which was developed by the Royal Navy, fired up to 24 spigot mortars ahead of a ship when attacking a U Boat and it was deployed on convoy escort warships such as destroyers and corvettes to supplement the depth charges. Statistics show that in the Second World War out of 5,174 British depth charge attacks there were 85.5 kills, in comparison, the Hedgehog made 268 attacks for 47 kills, a ratio of 5.7 to 1. Although a failure, the Fairlie was designed to fire depth charges ahead of a ship when attacking a submarine and this principle of forward-firing projectiles was considered viable. It was from this, secret research undertaken by the Directorate of Miscellaneous Weapons Development led to the development of the Hedgehog, the weapon was a multiple spigot mortar or spigot discharger, a type of weapon developed between the wars by Lieutenant Colonel Stewart Blacker, RA. The spigot mortar was based on early infantry trench mortars, the spigot design allowed a single device to fire warheads of varying size. The propelling charge was part of the weapon and worked against a rod set in the baseplate which fitted inside a tubular tail of the bomb. This principle was first used on the Blacker Bombard 29mm Spigot Mortar, the adaptation of the bombard for naval use was made in partnership with MIR under Major Millis Jefferis who had taken Blackers design and brought it into use with Army. The weapon fires a salvo of 24 bombs in an arc, the mounting initially was fixed but was later replaced by a gyro-stabilised one to allow for the rolling and pitching of the attacking ship. The system was developed to solve the problem of the target submarine disappearing from the attacking ships ASDIC when the ship came within the minimum range. Carrying a Torpex charge weighing 16 kg, each mortar had a diameter of 18 cm, the projectiles were angled so they would land in a circular shape with a diameter of 40 m about 180 m ahead of a stationary ship. The projectiles would then sink at about 7 m/s and they would reach a submerged U boat, for example at 200 ft in under 9 seconds. Sympathetic detonation of projectiles near those contacting hard surfaces was a possibility, the prototype launcher was tested aboard HMS Westcott in 1941, but there were no submarine kills until November 1942, after it had been installed aboard one hundred ships. Initial success rates - of about 5% - were only better than depth charges. Swells and spray frequently covered the launcher during heavy North Atlantic weather, the disappointment of a quiet miss discouraged crews who might otherwise assume depth charge explosions had damaged their target or at least frightened the enemy. The Royal Navy launched hedgehog so seldom in early 1943 a directive was issued ordering captains of ships equipped with hedgehog to report why they had NOT used hedgehog on an underwater contact, the results were blamed on crew inexperience and low confidence in the weapon. By the end of the war, statistics showed that on average, in response to this new deadly threat to its U Boats, the Kriegsmarine brought forward its programme of acoustic torpedoes in 1943, beginning with the Falke. These new homing torpedoes could be employed effectively even without the use of a periscope, providing submarines a better chance to remain undetected, in the Pacific Theater, USS England sank six Japanese submarines in a matter of days with Hedgehog in May 1944

M2 Browning
–
The M2 Machine Gun or Browning.50 Caliber Machine Gun is a heavy machine gun designed toward the end of World War I by John Browning. Its design is similar to Brownings earlier M1919 Browning machine gun, the M2 uses the much larger and much more powerful.50 BMG cartridge, which was developed alongside and takes its name from the gun itself. It has been referred to as Ma Deuce, in reference to its M2 nomenclature, the design has had many specific designations, the official designation for the current infantry type is Browning Machine Gun, Cal.50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, the M2 has been produced longer than any other machine gun. The Browning.50 caliber machine gun has been used extensively as a vehicle weapon and it was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Iraq War and the War in Afghanistan in the 2000s and 2010s. It is the heavy machine gun of NATO countries, and has been used by many other countries as well. The M2 has been in use longer than any firearm in U. S. inventory except the.45 ACP M1911 pistol. The current M2HB is manufactured in the U. S. by General Dynamics, Ordnance for use by the U. S. government, and for allies via Foreign Military Sales, as well as foreign manufacturers such as FN Herstal. Machine guns were used in World War I, and weapons of larger than rifle caliber were appearing. Both the British and French had large caliber machine guns, the larger rounds were needed to defeat the armor that was being introduced to the battlefield. Armor was also appearing in the skies, during World War I, the Germans introduced a heavily armored airplane, the Junkers J. I. The armor made aircraft machine guns using conventional rifle ammunition ineffective, consequently, the American Expeditionary Forces commander General John J. Pershing asked for a larger caliber machine gun. Pershing asked the Army Ordnance Department to develop a gun with a caliber of at least 0.50 inches. U. S. Col. John Henry Parker, commanding a machine gun school in France, the Army Ordnance Department ordered eight experimental Colt machine guns rechambered for the French 11 mm cartridge. The French had developed a machine gun for an even larger caliber. The French 11 mm round was found to be unsuitable because its velocity was too low, Pershing wanted a bullet of at least 670 gr and a muzzle velocity of 2,700 ft/s. Development with the French round was dropped, around July 1917, John M. Browning started redesigning his.30 caliber machine gun for a larger caliber. Winchester worked on the cartridge, which was a version of the. 30-06

Machine gun
–
A machine gun is a fully automatic mounted or portable firearm designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Note that not all fully automatic firearms are machine guns, submachine guns, rifles, assault rifles, shotguns, pistols or cannons may be capable of fully automatic fire, but are not designed for sustained fire. Many machine guns also use belt feeding and open bolt operation, unlike semi-automatic firearms, which require one trigger pull per round fired, a machine gun is designed to fire for as long as the trigger is held down. Nowadays the term is restricted to heavy weapons, able to provide continuous or frequent bursts of automatic fire for as long as ammunition lasts. Machine guns are used against personnel, aircraft and light vehicles, or to provide suppressive fire. Some machine guns have in practice sustained fire almost continuously for hours, because they become very hot, practically all machine guns fire from an open bolt, to permit air cooling from the breech between bursts. They also usually have either a barrel cooling system, slow-heating heavyweight barrel, although subdivided into light, medium, heavy or general-purpose, even the lightest machine guns tend to be substantially larger and heavier than standard infantry arms. Medium and heavy guns are either mounted on a tripod or on a vehicle, when carried on foot. Medium machine guns use full-sized rifle rounds and are designed to be used from fixed positions mounted on a tripod. 50in, the M249 automatic rifle is operated by an automatic rifleman, but its ammunition may be carried by other Soldiers within the squad or unit. The M249 machine gun is a crew-served weapon, Machine guns usually have simple iron sights, though the use of optics is becoming more common. Many heavy machine guns, such as the Browning M2.50 caliber machine gun, are enough to engage targets at great distances. During the Vietnam War, Carlos Hathcock set the record for a shot at 7382 ft with a.50 caliber heavy machine gun he had equipped with a telescopic sight. This led to the introduction of.50 caliber anti-materiel sniper rifles, selective fire rifles firing a full-power rifle cartridge from a closed bolt are called automatic rifles or battle rifles, while rifles that fire an intermediate cartridge are called assault rifles. Unlocking and removing the spent case from the chamber and ejecting it out of the weapon as bolt is moving rearward Loading the next round into the firing chamber. Usually the recoil spring tension pushes bolt back into battery and a cam strips the new round from a feeding device, cycle is repeated as long as the trigger is activated by operator. Releasing the trigger resets the trigger mechanism by engaging a sear so the weapon stops firing with bolt carrier fully at the rear, the operation is basically the same for all autoloading firearms, regardless of the means of activating these mechanisms. Most modern machine guns use gas-operated reloading, a recoil actuated machine gun uses the recoil to first unlock and then operate the action. Machine guns such as the M2 Browning and MG42, are of this type, a cam, lever or actuator demultiplicates the energy of the recoil to operate the bolt

Rear admiral
–
Rear admiral is a naval commissioned officer rank above that of a commodore and captain, and below that of a vice admiral. It is generally regarded as the lowest of the admiral ranks, in many navies it is referred to as a two-star rank. It originated from the days of naval sailing squadrons and can trace its origins to the Royal Navy, each naval squadron would be assigned an admiral as its head, who would command from the centre vessel and direct the activities of the squadron. The admiral would in turn be assisted by a vice admiral and this has survived into the modern age, with the rank of rear admiral the most-junior of the admiralty ranks of many navies. In some European navies, and in the Canadian Forces French rank translations, in the German Navy the rank is known as Konteradmiral, superior to the flotilla admiral. In the Royal Netherlands Navy, this rank is known as schout-bij-nacht, denoting the role junior to the squadron admiral, the Royal Australian Navy maintains a rank of rear admiral, refer to Australian Defence Force ranks and insignia. Since the mid-1990s, the insignia of a Royal Australian Navy rear admiral is the Crown of St. Edward above a crossed sword and baton, like the Royal Navy version, the sword is a traditional naval cutlass. The stars have eight points, unlike the four pointed Order of the Bath stars used by the army, prior to 1995, the RAN shoulder board was identical to the Royal Navy shoulder board. The Royal Navy shoulder board changed again in 2001 and the Australian, rear Admiral Robyn Walker AM, RAN became the first female admiral in the Royal Australian Navy when she was appointed Surgeon-General of the Australian Defence Force on 16 December 2011. In the Royal Canadian Navy, the rank of rear-admiral is the Navy rank equivalent to major-general of the Army, a rear-admiral is a flag officer, the naval equivalent of a general officer. A rear-admiral is senior to a commodore and brigadier-general, and junior to a vice-admiral and lieutenant-general, the service dress features a wide strip of gold braid around the cuff and, since June 2010, above it a narrower strip of gold braid embellished with the executive curl. On the visor of the cap are two rows of gold oak leaves. Konteradmiral is an OF-7 two-star rank equivalent to the Generalmajor in the German Army, see also The Guyana Defence Force Coast Guard is the naval component of the Military of Guyana. As such, the ranks of the Coast Guard are naval ranks similar to the practice in the respective Coast Guards of Jamaica and Trinidad, the rank of rear admiral was first awarded to chief of staff commodore Gary Best on August 19,2013. The rank insignia consists of two silver pips with green highlights, beneath a crossed sword and baton, all surmounted by the gold-colored Caciques crown with red, the Indian Navy also maintains a rear admiral rank senior to commodore and captain ranks and junior to vice admiral ranks. The rank insignia for a rear-admiral is two stars beneath crossed sword and baton, all surmounted by Emblem of India, worn on shoulder boards, before Islamic Revolution The Iranian Imperial Navy. After Islamic Revolution The Islamic Republic of Iran Navy, also known as the Iranian Navy, a rear admiral in the Pakistani Navy is a senior and two-star rank naval officer, appointed in higher naval commands. Like most Commonwealth navies, the rear admiral rank is superior to commodore, however, the rank is junior to the three-star rank vice-admiral and four-star rank admiral, who is generally a Chief of Naval Staff of the Navy

United States Navy
–
The United States Navy is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. The U. S. Navy is the largest, most capable navy in the world, the U. S. Navy has the worlds largest aircraft carrier fleet, with ten in service, two in the reserve fleet, and three new carriers under construction. The service has 323,792 personnel on duty and 108,515 in the Navy Reserve. It has 274 deployable combat vessels and more than 3,700 operational aircraft as of October 2016, the U. S. Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was effectively disbanded as a separate entity shortly thereafter. It played a role in the American Civil War by blockading the Confederacy. It played the role in the World War II defeat of Imperial Japan. The 21st century U. S. Navy maintains a global presence, deploying in strength in such areas as the Western Pacific, the Mediterranean. The Navy is administratively managed by the Department of the Navy, the Department of the Navy is itself a division of the Department of Defense, which is headed by the Secretary of Defense. The Chief of Naval Operations is an admiral and the senior naval officer of the Department of the Navy. The CNO may not be the highest ranking officer in the armed forces if the Chairman or the Vice Chairman of the Joint Chiefs of Staff. The mission of the Navy is to maintain, train and equip combat-ready Naval forces capable of winning wars, deterring aggression, the United States Navy is a seaborne branch of the military of the United States. The Navys three primary areas of responsibility, The preparation of naval forces necessary for the prosecution of war. The development of aircraft, weapons, tactics, technique, organization, U. S. Navy training manuals state that the mission of the U. S. Armed Forces is to prepare and conduct prompt and sustained combat operations in support of the national interest, as part of that establishment, the U. S. Navys functions comprise sea control, power projection and nuclear deterrence, in addition to sealift duties. It follows then as certain as that night succeeds the day, that without a decisive naval force we can do nothing definitive, the Navy was rooted in the colonial seafaring tradition, which produced a large community of sailors, captains, and shipbuilders. In the early stages of the American Revolutionary War, Massachusetts had its own Massachusetts Naval Militia, the establishment of a national navy was an issue of debate among the members of the Second Continental Congress. Supporters argued that a navy would protect shipping, defend the coast, detractors countered that challenging the British Royal Navy, then the worlds preeminent naval power, was a foolish undertaking. Commander in Chief George Washington resolved the debate when he commissioned the ocean-going schooner USS Hannah to interdict British merchant ships, and reported the captures to the Congress

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Korean War
–
The Korean War began when North Korea invaded South Korea. The United Nations, with the United States as the principal force, China came to the aid of North Korea, and the Soviet Union gave some assistance. Korea was ruled by Japan from 1910 until the days of World War II. In August 1945, the Soviet Union declared war on Japan, as a result of an agreement with the United States, U. S. forces subsequently moved into the south. By 1948, as a product of the Cold War between the Soviet Union and the United States, Korea was split into two regions, with separate governments, both governments claimed to be the legitimate government of all of Korea, and neither side accepted the border as permanent. The conflict escalated into open warfare when North Korean forces—supported by the Soviet Union, on that day, the United Nations Security Council recognized this North Korean act as invasion and called for an immediate ceasefire. On 27 June, the Security Council adopted S/RES/83, Complaint of aggression upon the Republic of Korea and decided the formation, twenty-one countries of the United Nations eventually contributed to the UN force, with the United States providing 88% of the UNs military personnel. After the first two months of war, South Korean forces were on the point of defeat, forced back to the Pusan Perimeter, in September 1950, an amphibious UN counter-offensive was launched at Inchon, and cut off many North Korean troops. Those who escaped envelopment and capture were rapidly forced back north all the way to the border with China at the Yalu River, at this point, in October 1950, Chinese forces crossed the Yalu and entered the war. Chinese intervention triggered a retreat of UN forces which continued until mid-1951, after these reversals of fortune, which saw Seoul change hands four times, the last two years of fighting became a war of attrition, with the front line close to the 38th parallel. The war in the air, however, was never a stalemate, North Korea was subject to a massive bombing campaign. Jet fighters confronted each other in combat for the first time in history. The fighting ended on 27 July 1953, when an armistice was signed, the agreement created the Korean Demilitarized Zone to separate North and South Korea, and allowed the return of prisoners. However, no treaty has been signed, and the two Koreas are technically still at war. Periodic clashes, many of which are deadly, continue to the present, in the U. S. the war was initially described by President Harry S. Truman as a police action as it was an undeclared military action, conducted under the auspices of the United Nations. In South Korea, the war is referred to as 625 or the 6–2–5 Upheaval. In North Korea, the war is referred to as the Fatherland Liberation War or alternatively the Chosǒn War. In China, the war is called the War to Resist U. S

Vietnam War
–
It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The war is considered a Cold War-era proxy war. As the war continued, the actions of the Viet Cong decreased as the role. U. S. and South Vietnamese forces relied on air superiority and overwhelming firepower to conduct search and destroy operations, involving ground forces, artillery, in the course of the war, the U. S. conducted a large-scale strategic bombing campaign against North Vietnam. The North Vietnamese government and the Viet Cong were fighting to reunify Vietnam and they viewed the conflict as a colonial war and a continuation of the First Indochina War against forces from France and later on the United States. The U. S. government viewed its involvement in the war as a way to prevent a communist takeover of South Vietnam and this was part the domino theory of a wider containment policy, with the stated aim of stopping the spread of communism. Beginning in 1950, American military advisors arrived in what was then French Indochina, U. S. involvement escalated in the early 1960s, with troop levels tripling in 1961 and again in 1962. Regular U. S. combat units were deployed beginning in 1965, despite the Paris Peace Accord, which was signed by all parties in January 1973, the fighting continued. In the U. S. and the Western world, a large anti-Vietnam War movement developed as part of a larger counterculture, the war changed the dynamics between the Eastern and Western Blocs, and altered North–South relations. Direct U. S. military involvement ended on 15 August 1973, the capture of Saigon by the North Vietnamese Army in April 1975 marked the end of the war, and North and South Vietnam were reunified the following year. The war exacted a huge human cost in terms of fatalities, estimates of the number of Vietnamese soldiers and civilians killed vary from 966,000 to 3.8 million. Some 240, 000–300,000 Cambodians,20, 000–62,000 Laotians, and 58,220 U. S. service members died in the conflict. Various names have applied to the conflict. Vietnam War is the most commonly used name in English and it has also been called the Second Indochina War and the Vietnam Conflict. As there have been several conflicts in Indochina, this conflict is known by the names of its primary protagonists to distinguish it from others. In Vietnamese, the war is known as Kháng chiến chống Mỹ. It is also called Chiến tranh Việt Nam, France began its conquest of Indochina in the late 1850s, and completed pacification by 1893. The 1884 Treaty of Huế formed the basis for French colonial rule in Vietnam for the seven decades

Ship breaking
–
It may also be known as ship dismantling, ship cracking, or ship recycling. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue, ship breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process, equipment on board the vessel can also be reused. While ship breaking is sustainable, there are concerns about the use of poorer countries without stringent environmental legislation and it is also considered one of the worlds most dangerous industries and very labour-intensive. In 2012, roughly 1,250 ocean ships were broken down, in 2013, the world total of demolished ships amounted to 29,052,000 tonnes, 92% of which were demolished in Asia. The largest sources of ships are states of China, Greece and Germany respectively, the ship breaking yards of India, Bangladesh, China and Pakistan employ 100,000 workers as well as providing a large amount of indirect jobs. In India, the steel covers 10% of the countrys needs. As an alternative to breaking, ships may be sunk to create artificial reefs after being cleared of hazardous materials. Storage is a viable option, whether on land or afloat, though all ships will be eventually scrapped, sunk. Wooden-hulled ships were set on fire or conveniently sunk. In Tudor times, ships were dismantled and the timber re-used. This procedure was no longer applicable with the advent of metal-hulled boats, the navy vessel HMS Temeraire had her masts, stores and guns removed and her crew paid off. She was sold by Dutch auction on 16 August 1838 to John Beatson, Beatson was then faced with the task of transporting the ship 55 miles from Sheerness to Rotherhithe, the largest ship to have attempted this voyage. To accomplish this he hired two steam tugs from the Thames Steam Towing Company and employed a Rotherhithe pilot named William Scott and twenty five men to sail her up the Thames, at a cost of £58. The shipbreakers undertook a thorough dismantling, removing all the copper sheathing, rudder pintles and gudgeons, copper bolts, nails, the timber was mostly sold to house builders and shipyard owners, though some was retained for working into specialist commemorative furniture. The ships final voyage was immortalised by William Turners painting The Fighting ‘Temeraire’, in 1880, Denny Brothers of Dumbarton used scrap maritime steel in their shipbuilding. Many other nations began to purchase British ships for scrap by the late 19th century, including Germany, Italy, the Italian industry started in 1892, and the Japanese after an 1896 law had been passed to subsidise native shipbuilding. After being damaged or involved in a disaster, liner operators did not want the name of the ship to tarnish the brand of their passenger services

USS Helena (CL-50)
–
USS Helena was a St. Louis-class light cruiser of the United States Navy. Completed shortly before World War II, she was damaged in the attack on Pearl Harbor and she was sunk by three surface-fired torpedoes at the battle of Kula Gulf in 1943. She was one of three U. S. light cruisers to be sunk during the war, in November 1942, Helena became the first US Navy ship to be awarded the Navy Unit Commendation medal. Four United States Naval vessels have carried the name of Helena, as of October 2015 The first ship was the gunboat Helena, in service from 1896 to 1932. She saw action in Cuban waters during the Spanish–American War and later joined the Asiatic squadron for the Philippine Insurrection and was part of the Yangtze, the second ship of the name was Helena, a light cruiser in service from 1939 to 1943. Damaged at Pearl Harbor on 7 December 1941, she sailed again to action at Guadalcanal, Savo Island, and Cape Esperance where she sank a Japanese cruiser and she was lost in Kula Gulf in 1943 with 165 of her crew. Her survivors call her the ship that went in harms way. In late 1944, war bonds raised in Montana were used to purchase the ship to carry the name Helena. She was launched 28 April 1945 and commissioned on 4 September 1945 and she saw distinguished service in European and Chinese waters and combat service in Korea. During that time, the Helena served as flagship of the US Pacific Fleet and she became flagship of the First Fleet in 1961. Until her decommissioning on 29 June 1963, her crew gave financial assistance to disabled children in Helena and she was sold for scrap in 1974. Her brass propeller and some chains were procured by the City of Helena. The fourth and newest Helena, Helena, is a Los Angeles-class nuclear submarine and she was built at the Electric Boat Company in Groton, Connecticut in 1986 and commissioned in 1987. Assigned to the Pacific Fleet, she serves as a potent part of Americas defense capability, Helenas insignia depicts the citys iconic fire tower. The St. Louis-class cruisers were a two ship class consisting of St. Louis and Helena, the United States did not favor this outcome, being of the opinion that the heavier-gunned ships more suited its needs in the Pacific. Brooklyn-class designs started in 1930, with the first four ships of the class ordered in 1933, various combinations of armor and power plants were tried in the efforts to stay below the Treatys 10,000 ton limit. The General Naval Board, in questioning 1935 changes to the London Naval Treaty, the St. Louis class had newer and improved higher-pressure boilers, and the boiler arrangement used the unit system of alternating boiler and engine rooms. This was to prevent a ship from being immobilized by an unlucky hit

Keel laying
–
Laying the keel or laying down is the formal recognition of the start of a ships construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company, keel laying is one of the four specially-celebrated events in the life of a ship, the others are launching, commissioning, and decommissioning. In earlier times, the event recognized as the keel laying was the placement of the central timber making up the backbone of a vessel. As steel ships replaced wooden ones, the central timber gave way to a steel beam. Modern ships are now built in a series of pre-fabricated. The event recognized as the keel laying is the first joining of modular components and it is now often called keel authentication, and is the ceremonial beginning of the ships life, although modules may have been started months before that stage of construction. Keel-related traditions from the times of wooden ships are said to bring luck to the ship during construction and to the captain, the first milestone in the history of a ship is the generally simple ceremony that marks the laying of the keel. Invitations to the ceremony are issued by officials, and the ceremony is conducted by them. The builder may be the commander of a shipyard or the president of a private company. The ships prospective name, without the USS, is mentioned in the invitation, if known, otherwise her type and number are given, e. g. DD2217

Kearny, New Jersey
–
Kearny is a town in Hudson County, New Jersey, United States and a suburb of Newark. Kearny is named after Civil War general Philip Kearny and it began as a township formed by an act of the New Jersey Legislature on April 8,1867, from portions of Harrison Township. Portions of the township were taken on July 3,1895, Kearny was incorporated as a town on January 19,1899, based on the results of a referendum held two days earlier. The Arlington section of town was named for Arlington Station on the Erie Railroad at the Arlington Mill plant, owned by Arlington Mills of Lawrence, Massachusetts. The area of Kearny Township, created in 1867, had part of the original Crown Grant of 30,000 acres obtained by Major William Sandford of Barbados on July 4,1668. Major Sandford named it New Barbadoes Neck after his old home, as was the custom of the time, the Major paid 20 pounds sterling to Chief Tantaqua of the Hackensack tribe for all their reserve rights and titles. Sanfords friend Major Nathaniel Kingsland acquired the property in 1708 and sold the western tract of the Grant for 300 pounds sterling to Captain Arent Schuyler two years later. The new purchase included present-day Kearny, North Arlington, Lyndhurst, shortly after Schuylers purchase of his new homestead, a peculiar green stone was uncovered. It was sent to England for analysis and he learned that it contained 80% copper and his opening of a copper mine brought the first steam engine to America from England, it was used to pump out the deep mine shaft. The engine was delivered by its engineer, Josiah Hornblower. The engine and mines were destroyed by fire in 1772 and remained idle for some years, Schuyler Mansion played a role during the American Revolutionary War Era. When Lord Howe of England took possession of New York Harbor and they generally traveled over a road that today is referred to as the Belleville Turnpike, which was originally constructed in 1759 using cedar logs from the nearby swamps. In the middle 19th century, Kearny was the upper, or northern, a prominent citizen and resident of the upper section, General N. M. Halsted, felt it was impossible under these political conditions for his section to obtain proper recognition. He engaged an energetic campaign for an independent township and he succeeded when the NJ Legislature of 1867 on March 14, adopted an act creating the Township of Kearny. The town was named to honor Major General Phil Kearny, Commander of the New Jersey Forces in the Civil War, on April 8,1867, the first election of town officers was held. General N. M. Halsted was elected Chairman, the first official seat of Government was three rooms in the old Lodi Hotel, on the northeast corner of Schuyler and Harrison Avenues. In the early 1870s, Kearny erected its first Town Hall, on the corner of Kearny and Woodland Avenues and this served as a Town Hall, Court House, and Schoolhouse. The Minute Book of the Township states on August 16,1870, the first schoolhouse was housed in the Town Hall built at Kearny and Woodland Avenues in 1873

Ceremonial ship launching
–
Ceremonial ship launching is the process of transferring a vessel to the water. It is a tradition in many cultures, dating back thousands of years. It has been observed as a celebration and a solemn blessing. The process also involves many traditions intended to invite good luck, such as christening by breaking a bottle of champagne over the bow as the ship is named aloud. There are three methods of conveying a new ship from building site to water, only two of which are called launching. The oldest, most familiar, and most widely used is the launch, in which the vessel slides down an inclined slipway. With the side launch, the ship enters the water broadside and this method came into use in the 19th-century on inland waters, rivers, and lakes, and was more widely adopted during World War II. The third method is float-out, used for ships that are built in basins or dry docks and then floated by admitting water into the dock. In all cases, heavy chains are attached to the ship, normally, ways are arranged perpendicular to the shore line and the ship is built with its stern facing the water. The barricades support the two launch ways, the vessel is built upon temporary cribbing that is arranged to give access to the hulls outer bottom and to allow the launchways to be erected under the complete hull. When it is time to prepare for launching, a pair of standing ways is erected under the hull, the surface of the ways is greased. A pair of sliding ways is placed on top, under the hull, the weight of the hull is then transferred from the build cribbing onto the launch cradle. On launching, the vessel slides backwards down the slipway on the ways until it floats by itself, some slipways are built so that the vessel is side-on to the water and is launched sideways. This is done where the limitations of the channel would not allow lengthwise launching. The Great Eastern designed by Brunel was built this way as were many landing craft during World War II and this method requires many more sets of ways to support the weight of the ship. Sometimes ships are launched using a series of inflated tubes underneath the hull and this procedure has the advantages of requiring less permanent infrastructure, risk, and cost. The airbags provide support to the hull of the ship and aid its launching motion into the water and these airbags are usually cylindrical in shape with hemispherical heads at both ends. The Xiao Qinghe shipyard launched a tank barge with marine airbags on January 20,1981, egyptians, Greeks, and Romans called on their gods to protect seamen

Ship commissioning
–
Ship commissioning is the act or ceremony of placing a ship in active service, and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to the placing of a warship in active duty with its countrys military forces, the ceremonies involved are often rooted in centuries old naval tradition. Ship naming and launching endow a ship hull with her identity, the engineering plant, weapon and electronic systems, galley, and multitudinous other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ships officers, the petty officers, prior to commissioning, the new ship undergoes sea trials to identify any deficiencies needing correction. USS Monitor, of American Civil War fame, was commissioned less than three weeks after launch, regardless of the type of ship in question, a vessels journey towards commissioning in its nations navy begins with process known as sea trials. Sea trials begin when the ship in question is floated out of its dry dock, after a ship has successfully cleared its sea trial period, it will officially be accepted into service with its nations navy. At this point, the ship in question will undergo a process of degaussing and/or deperming, once a ships sea trials are successfully completed plans for the actual commissioning ceremony will take shape. If the ships ceremony is an affair the Captain may make a speech to the audience. Religious ceremonies, such as blessing the ship or the singing of hymns or songs. Once a ship has been commissioned its final step toward becoming a unit of the navy it now serves is to report to its home port. To decommission a ship is to terminate its career in service in the forces of a nation. Decommissioning of the vessel may also occur due to treaty agreements or for safety reasons, vessels preserved in this manner typically do not relinquish their names to other, more modern ships that may be in the design, planning, or construction phase of the parent nations navy. Prior to its decommissioning, the ship in question will begin the process of decommissioning by going through a preliminary step called inactivation or deactivation. The removed material from a ship usually ends up either rotating to another ship in the class with similar weapons and/or capabilities, or in storage pending a decision on equipments fate. During this time a crew may be thinned out via transfers. When a ship finishes its inactivation, it is then formally decommissioned, often, but not always, ships that are decommissioned end up spending the next few years in a reserve fleet before their ultimate fate is decided. Commissioning in the early United States Navy under sail was attended by no ceremony, thus, the ship was placed in commission. Commissionings were not public affairs, and unlike christening-and-launching ceremonies, were not recorded by newspapers, the first specific reference to commissioning located in naval records is a letter of November 6,1863, from Secretary of the Navy Gideon Welles to all navy yards and stations

Battle of Kolombangara
–
The Battle of Kolombangara was a naval battle of the Pacific campaign of World War II, fought on the night of 12/13 July 1943, off Kolombangara in the Solomon Islands. An Allied force—commanded by Rear Admiral Walden L. Ainsworth and comprising the United States Navy light cruisers USS Honolulu, the U. S. Admiral Ainsworths mission was to protect the north shore beachhead from attack by the Tokyo Express and if possible to prevent Imperial reinforcements from landing. At 01,00 on 13 July, the Allied ships established radar contact about 20 mi east of the tip of Kolombangara at 7°50′S 157°21′E. Ainsworth assumed he had complete surprise, but the Japanese had been aware of the Allied force for almost two hours, Jintsu engaged the Allied ships and was subjected to concentrated Allied fire. She was reduced to a wreck, broken in two by torpedo hits and sank at about 01,45, with the loss of nearly her entire crew, including Vice Admiral Izaki. On the Allied side, Leander was struck by a torpedo and, severely damaged, retired from the battle escorted by Radford and Jenkins. Ainsworth pursued the Imperial destroyers, but both St. Louis and Honolulu were struck by torpedoes and damaged, while Gwin was struck amidships and scuttled at 09,30 the next morning. Honolulu and St. Louis were out of action for months, while Leander was under repair for a year. Except for Jintsu, the Japanese force escaped damage, and the transport destroyers successfully landed 1,200 men at Vila. The Emperors men had won a victory, but of the action the naval historian Samuel Eliot Morison wrote.

Battle of Kula Gulf
–
The naval Battle of Kula Gulf took place in the early hours of 6 July 1943 during World War II and was between United States and Japanese ships off the coast of Kolombangara in the Solomon Islands. In support of landing, which was to set up an initial beachhead for moving U. S. A U. S. Marine landing was scheduled on the shore of New Georgia on 10 July. The Japanese were divided into two forces, a formation of three escorts trailing the main column first came under attack. The U. S. ships opened fire at 01,57, firing 612 shells in 21 minutes and six seconds, quickly sinking the destroyer Niizuki and killing Admiral Akiyama. However, Helena had expended all of her flashless powder the previous night, she was forced to use smokeless powder, Two of the Japanese destroyers launched their Long Lance torpedoes and hit Helena, fatally damaging her. The main Japanese force, which had countermarched away from Vila with the first contact, then broke away, the Japanese destroyer Nagatsuki ran aground, while Hatsuyuki was damaged. Both forces began to withdraw from the area, but one Japanese, at about 05,00, the destroyers Amagiri and USS Nicholas exchanged torpedoes and gunfire. The beached Nagatsuki was abandoned by her crew in the morning, the destroyers USS Radford and Nicholas both stayed behind to rescue survivors from Helena. While rescuing over 750 men, Radford and Nicholas had to reengage the enemy three times, they were awarded the Presidential Unit Citation for their rescue. The U. S.

Tokyo Express
–
The original name of the resupply missions was The Cactus Express, coined by Allied forces on Guadalcanal, using the codename for the island. After the U. S. press began referring to it as the Tokyo Express, apparently in order to preserve operational security for the codeword Cactus, the Japanese called the night resupply missions Rat Transportation, because they took place at night. Delivery of troops and material by slow transport ships to Japanese forces on Guadalcanal, a typical night in December resulted in 1500 drums being rolled into the sea, with only 300 recovered. The warship formations assigned to Express missions were often designated as the Reinforcement Unit. John F. Kennedys PT-109 was lost on a planned and uncoordinated attack on the Tokyo Express. 15 PT boats with 60 torpedoes did not register a single hit, the PT-109 was struck by the destroyer Amagiri returning from her supply run, estimated to be traveling in excess of 30 knots with no running lights.

Presidential Unit Citation (United States)
–
The unit with the most Presidential Unit Citations is the USS Parche with 9 citations. The Army citation was established by Executive Order 9075 on 26 February 1942, superseded by Executive Order 9396 on Dec.2,1943, as with other Army unit citations, the PUC is in a larger frame than other ribbons, and is worn above the right pocket. All members of the unit may wear the decoration, whether or not they participated in the acts for which the unit was cited. Only those assigned to the unit at the time of the action cited may wear the decoration as a permanent award, for both the Army and Air Force, the emblem is a solid blue ribbon enclosed in a gold frame. The Air Force PUC was adopted from the Army Distinguished Unit Citation after the Air Force became a military branch in 1947. By Executive Order 10694, dated Jan,10,1957 the Air Force redesignated the Distinguished Unit Citation as the Presidential Unit Citation. The Air Force PUC is the color and design as the Army PUC but slightly smaller. The Citation is carried on the units colors in the form of a blue streamer,4 ft long and 2.75 in wide. For the Army, only on rare occasions will a larger than battalion qualify for award of this decoration. The Navy citation was established by Executive Order 9050 on 6 February 1942, the Navy version has blue, yellow, and red horizontal stripes, and is the only Navy ribbon having horizontal stripes. These are only worn by persons who meet the criteria at the time it is awarded to the unit, unlike the Army, those who later join the unit do not wear it on a temporary basis. The current decoration is known as the Department of Homeland Security Presidential Unit Citation. A Coast Guard version of the award was awarded to all U. S. Coast Guard and Coast Guard Auxiliary personnel responding to Hurricane Katrina by President George W. Bush for rescue, the United States Public Health Service Presidential Citation was established in 2015. The design was finalized by the Army Institute of Heraldry on 17 August 2015, two units of the Free French Forces were awarded Presidential Unit Citations during World War II. On April 22,1986, the 1st Fighter Group Força Aérea Brasileira was awarded the Presidential Unit Citation for its actions in the Po Valley region of Italy in World War II. The Brazilians, operating in Italy in support of Allied forces, destroyed in one day over 45 vehicles, strafed pontoon bridges on the River Po, eleven missions of 44 sorties were flown destroying nine motor transports and damaging 17. One Belgian-Luxembourgian battalion of the Belgian United Nations Command was awarded the Presidential Unit Citation once for actions during the Battle of the Imjin River, the Colombia Battalion received the citation while attached to the American 21st Infantry Regiment in 1951. One Dutch unit, the Netherlands Detachment United Nations, part of the Regiment Van Heutsz, was awarded the Presidential Unit Citation twice for actions during the Korean War, the first citation was awarded after the battle near Wonju and Hoengson in February 1951

Cruiser
–
A cruiser is a type of warship. The term has been in use for several hundred years, and has had different meanings throughout this period. In the middle of the 19th century, cruiser came to be a classification for the intended for cruising distant waters, commerce raiding. Cruisers came in a variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big as a pre-dreadnought battleship. With the advent of the battleship before World War I. The very large battlecruisers of the World War I era that succeeded armored cruisers were now classified, along with dreadnought battleships, in the later 20th century, the obsolescence of the battleship left the cruiser as the largest and most powerful surface combatant after the aircraft carrier. The role of the cruiser varied according to ship and navy, often including air defense, during the Cold War, the Soviet Navys cruisers had heavy anti-ship missile armament designed to sink NATO carrier task forces via saturation attack. The U. S. Adams guided-missile destroyers tasked with the air defense role. Indeed, the newest U. S. Navy destroyers are more heavily-armed than some of the cruisers that they succeeded, currently only three nations operate cruisers, the United States, Russia, and Peru. The term cruiser or cruizer was first commonly used in the 17th century to refer to an independent warship, Cruiser meant the purpose or mission of a ship, rather than a category of vessel. However, the term was used to mean a smaller, faster warship suitable for such a role. The Dutch navy was noted for its cruisers in the 17th century, while the Royal Navy—and later French and Spanish navies—subsequently caught up in terms of their numbers, during the 18th century the frigate became the preeminent type of cruiser. A frigate was a small, fast, long range, lightly armed ship used for scouting, carrying dispatches, the other principal type of cruiser was the sloop, but many other miscellaneous types of ship were used as well. During the 19th century, navies began to use steam power for their fleets, the 1840s saw the construction of experimental steam-powered frigates and sloops. By the middle of the 1850s, the British and U. S. Navies were both building steam frigates with very long hulls and a gun armament, for instance USS Merrimack or Mersey. The 1860s saw the introduction of the ironclad, the first ironclads were frigates, in the sense of having one gun deck, however, they were also clearly the most powerful ships in the navy, and were principally to serve in the line of battle. In spite of their speed, they would have been wasted in a cruising role. The French constructed a number of smaller ironclads for overseas cruising duties, starting with the Belliqueuse and these station ironclads were the beginning of the development of the armored cruisers, a type of ironclad specifically for the traditional cruiser missions of fast, independent raiding and patrol

USS O'Brien (DD-415)
–
Since this warship was built in a drydock, along with the destroyers Walke, Lansdale, and Madison, the christening and commissioning ceremonies were combined. Following her commissioning, OBrien operated along the Eastern Seaboard of the United States, transiting the Panama Canal on 20 January, the trio of ships arrived in San Francisco, California, on 31 January. OBrien steamed with a convoy for the Western Pacific on 4 February 1942, following repairs at the Mare Island Navy Yard, the destroyer steamed out again on 20 February, bound for Pearl Harbor. There Commander Destroyer Division 4 shifted his flag to O’Brien on 5 March 1942, the two warships returned to Pearl Harbor on 3 April. The destroyer then joined convoys from San Diego and San Francisco to escort them to American Samoa, OBrien was retained at Pago Pago for local escort work. On 26 May, she supported the occupation of Wallis Island, previously taken over by the Free French, operating out of Pearl Harbor, the ship performed escort duty and acted as patrol and plane guard. She got underway on 17 August with Task Force 17 to reinforce the South Pacific Force, while escorting a convoy of troop transports en route to Guadalcanal, the combined Task Forces 17 and 18 were attacked by the Japanese submarine I-19 on 15 September 1942. The aircraft carrier Wasp was sunk, and the battleship North Carolina, at 1452, O’Brien sighted smoke coming from Wasp. As a member of the aircraft carrier Hornets ASW screen, she made a turn to the right. At about 1454, while accelerating and swinging right, her lookouts spotted a torpedo two points forward of the beam,1,000 yards away. This torpedo then missed OBrien close astern, but while her crews attention was concentrated on it and this explosion did little obvious damage, but it set up severe structural stresses throughout the framework of OBrien. She was able to proceed under her own power, and on 16 September she reached Espiritu Santo, O’Brien next steamed out on 21 September, bound for Noumea, New Caledonia, for further repairs by the repair ship Argonne. Then, she steamed out on 10 October, bound for San Francisco Bay, OBrien made it to Suva in the New Hebrides on 13 October, and then steamed out once more on 16 October. The rate of leakage of seawater into OBrien continued to increase, large amounts of topside weights were jettisoned, and preparations were made for abandoning the ship, but her captain still thought that she could be taken intact to Pago Pago. However, at about 0600 on 19 October, her bottom suddenly split open considerably, at 0630, all hands except for a small salvage crew abandoned, but half an hour later OBrien was abandoned entirely. Just before 0800 she descended beneath the waves, and after steaming nearly 3,000 nautical miles since she had been torpedoed, all members of her crew were saved. USS OBrien earned one star during World War II. This article incorporates text from the public domain Dictionary of American Naval Fighting Ships, the entry can be found here

USS Wasp (CV-7)
–
USS Wasp was a United States Navy aircraft carrier commissioned in 1940 and lost in action in 1942. She was the ship named USS Wasp, and the sole ship of a class built to use up the remaining tonnage allowed to the U. S. for aircraft carriers under the treaties of the time. As a reduced-size version of the Yorktown-class aircraft carrier hull, Wasp was more vulnerable than other United States aircraft carriers available at the opening of hostilities, Wasp was initially employed in the Atlantic campaign, where Axis naval forces were perceived as less capable of inflicting decisive damage. After supporting the occupation of Iceland in 1941, Wasp joined the British Home Fleet in April 1942, Wasp was then transferred to the Pacific in June 1942 to replace losses at the battles of Coral Sea and Midway. After supporting the invasion of Guadalcanal, Wasp was sunk by the Japanese submarine I-19 on 15 September 1942, Wasp was a product of the Washington Naval Treaty. After the construction of the carriers Yorktown and Enterprise, the U. S. was still permitted 15,000 long tons to build a carrier, the Navy sought to squeeze a large air group onto a ship with nearly 25% less displacement than the Yorktown-class. In order to weight and space, Wasp was constructed with low-power machinery. Additionally, Wasp was launched with almost no armor, modest speed and, more significantly, absence of side protection of the boilers and internal aviation fuel stores doomed her to a blazing demise. These were inherent design flaws that were recognized when constructed but could not be remedied within the allowed tonnage and these flaws, combined with a relative lack of damage control experience in the early days of the war, were to prove fatal. Wasp was the first carrier fitted with a deck edge elevator, the elevator consisted of a platform for the front wheels and an outrigger for the tail wheel. The two arms on the sides moved the platform in a half-circle up and down between the deck and the hangar deck. Wasp remained at Boston through May, fitting out, before she got underway on 5 June 1940 for calibration tests on her radio direction finder gear. After further fitting out while anchored in Boston harbor, the new aircraft carrier steamed independently to Hampton Roads, Virginia, four days later, she sailed for the Caribbean in company with the destroyer Morris. En route, she conducted the first of many carrier qualification tests, among the earliest of the qualifiers was Lieutenant, junior grade David McCampbell, who later became the Navys top-scoring ace in World War II. Wasp arrived at Guantanamo Bay Naval Base in time to ship in honor of Independence Day. A fatal incident marred the carriers shakedown, on 9 July, one of her Vought SB2U-2 Vindicator dive bombers crashed 2 nautical miles from the ship. Wasp bent on speed to close, as did the plane-guarding destroyer Morris. The latters boats recovered items from the baggage compartment

Japanese submarine I-19
–
I-19 was a Japanese Type B1 submarine which damaged and destroyed several enemy ships during World War II while serving in the Imperial Japanese Navy. During the Guadalcanal Campaign, with a torpedo salvo, the submarine sank the aircraft carrier USS Wasp and the destroyer USS OBrien. Captain Tameichi Hara claims to have received word while anchored at Chuuk to the effect that Lt Cmdr Takaichi Kinashi was skipper of I-19, three of the torpedoes hit USS Wasp, causing heavy damage. With power knocked out due to damage from the explosions, USS Wasp’s damage-control teams were unable to contain the ensuing fires. Significant damage had been sustained by North Carolina, which underwent repairs at Pearl Harbor until November 16,1942 and this single torpedo salvo thus sank an aircraft carrier and a destroyer, and severely damaged a battleship, making it one of the most damaging torpedo salvos in history. From November,1942, until February,1943, I-19 assisted with the supply and reinforcement deliveries. These missions were labeled the Tokyo Express by Allied forces, between April and September,1943, I-19 was stationed off Fiji. During this time, the submarine sank two Allied cargo ships and heavily damaged one, after sinking one of the ships— SS William K. Vanderbilt— on May 16,1943, I-19 surfaced and machine-gunned the surviving crew members in their lifeboats, killing one of them. On November 25,1943, at 20,49,50 nautical miles west of Makin Island, after I-19 submerged, Radford attacked her with depth charges. I-19 was lost with all hands in this attack, I-19 was the number of the submarine commanded by Toshiro Mifune in the Steven Spielberg movie 1941.

Naval mine
–
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, Naval mines can be used offensively—to hamper enemy shipping movements or lock vessels into a harbour, or defensively—to protect friendly vessels and create safe zones. Mines can be laid in many ways, by purpose-built minelayers, refitted ships, submarines and their flexibility and cost-effectiveness make mines attractive to the less powerful belligerent in asymmetric warfare. The cost of producing and laying a mine is usually anywhere from 0. 5% to 10% of the cost of removing it, parts of some World War II naval minefields still exist because they are too extensive and expensive to clear. It is possible for some of these 1940s-era mines to remain dangerous for many years to come, Mines have been employed as offensive or defensive weapons in rivers, lakes, estuaries, seas, and oceans, but they can also be used as tools of psychological warfare. Offensive mines are placed in enemy waters, outside harbours and across important shipping routes with the aim of sinking both merchant and military vessels. Defensive minefields safeguard key stretches of coast from enemy ships and submarines, forcing them into more easily defended areas, minefields designed for psychological effect are usually placed on trade routes and are used to stop shipping from reaching an enemy nation. They are often spread thinly, to create an impression of minefields existing across large areas, a single mine inserted strategically on a shipping route can stop maritime movements for days while the entire area is swept. International law requires nations to declare when they mine an area, the warnings do not have to be specific, for example, during World War II, Britain declared simply that it had mined the English Channel, North Sea, and French coast. Chinese records tell of naval explosives in the 16th century, used to fight against Japanese pirates and this kind of naval mine was loaded in a wooden box, sealed with putty. General Qi Jiguang made several timed, drifting explosives, to harass Japanese pirate ships, although this is the rotating steel wheellocks first use in naval mines, Jiao Yu had described their use for land mines back in the 14th century. The first plan for a sea mine in the West was by Ralph Rabbards, the Dutch inventor Cornelius Drebbel was employed in the Office of Ordnance by King Charles I of England to make weapons, including a floating petard which proved a failure. Weapons of this type were apparently tried by the English at the Siege of La Rochelle in 1627, American David Bushnell developed the first American naval mine for use against the British in the American War of Independence. It was a watertight keg filled with gunpowder that was floated toward the enemy and it was used on the Delaware River as a drift mine. In 1812 Russian engineer Pavel Shilling exploded a mine using an electrical circuit. Russian naval specialists set more than 1500 naval mines, or infernal machines, designed by Moritz von Jacobi and by Immanuel Nobel, the mining of Vulcan led to the worlds first minesweeping operation. During the next 72 hours,33 mines were swept, the Jacobi mine was designed by German born, Russian engineer Jacobi, in 1853. The mine was tied to the sea bottom by an anchor, a cable connected it to a cell which powered it from the shore

Luzon
–
Luzon (/luːˈzɒn/, Tagalog pronunciation, is the largest and most populous island in the Philippines. It is ranked 15th largest in the world, with a population of 52.99 million as of 2015, it is the fourth most populous island in the world, containing about 53% of the countrys total population. Luzon may also refer to one of the three island groups in the country. The name Luzon is thought to derive from the Tagalog word lusong, from just before the first millennium, the Tagalog and Kapampangan peoples of south and central Luzon had established several Indianized kingdoms, notably among them those of Tundok and Namayan. The Laguna Copperplate Inscription, the first Philippine document written in 900AD, names places in and these kingdoms were based on leases between village rulers and landlords or Rajahs, to whom tributes and taxes were levied. These kingdoms were coastal thalassocracies based on trade with neighboring Asian political entities at that time, some parts of Luzon were Islamized when the Sultanate of Brunei expanded its realms from Borneo to the Philippines and set up the Kingdom of Maynila as its puppet-state. In addition, other kingdoms like the Wangdom of Pangasinan had become tributary states to China and were largely Sinified kingdoms, certain kilns were renowned over others and prices depended on the reputation of the kiln. Of this flourishing trade, the Burnay jars of Ilocos are the large clay jar manufactured in Luzon today with origins from this time. The Yongle Emperor instituted a Chinese Governor on Luzon during Zheng Hes voyages, China also had vassals among the leaders in the archipelago. China attained ascendancy in trade with the area in Yongles reign, in the 1500s, people from Luzon were called Lucoes and were actively employed in trading, seafaring and military campaigns across Southeast Asia. The Portuguese were the first European explorers who recorded it in their charts as Luçonia or Luçon, edmund Roberts, who visited Luzon in the early 19th century, wrote that Luzon was discovered in 1521. Many people from Luzon had active-employment in Portuguese Malacca and his father and wife carried on his maritime trading business after his death. Another important Malacca trader was Curia de Raja who also hailed from Luzon, the surname of de Raja or diraja could indicate that Regimo and Curia, and their families, were of noble or royal descent as the term is an abbreviation of Sanskrit adiraja. Pinto noted that there were a number of Lucoes in the Islamic fleets that went to battle with the Portuguese in the Philippines during the 16th century, the Sultan of Aceh gave one of them the task of holding Aru in 1540. Pinto also says one was named leader of the Malays remaining in the Moluccas Islands after the Portuguese conquest in 1511, pigafetta notes that one of them was in command of the Brunei fleet in 1521. However, the Luções did not only fight on the side of the Muslims, pinto says they were also apparently among the natives of the Philippines who fought the Muslims in 1538. On Mainland Southeast Asia, Lusung/Lucoes warriors aided the Burmese king in his invasion of Siam in 1547 AD, at the same time, Lusung warriors fought alongside the Siamese king and faced the same elephant army of the Burmese king in the defence of the Siamese capital at Ayuthaya. Scholars have thus suggested that they could be valued by all sides

San Francisco
–
San Francisco, officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California. It is the birthplace of the United Nations, the California Gold Rush of 1849 brought rapid growth, making it the largest city on the West Coast at the time. San Francisco became a consolidated city-county in 1856, after three-quarters of the city was destroyed by the 1906 earthquake and fire, San Francisco was quickly rebuilt, hosting the Panama-Pacific International Exposition nine years later. In World War II, San Francisco was a port of embarkation for service members shipping out to the Pacific Theater. Politically, the city votes strongly along liberal Democratic Party lines, San Francisco is also the headquarters of five major banking institutions and various other companies such as Levi Strauss & Co. Dolby, Airbnb, Weebly, Pacific Gas and Electric Company, Yelp, Pinterest, Twitter, Uber, Lyft, Mozilla, Wikimedia Foundation, as of 2016, San Francisco is ranked high on world liveability rankings. The earliest archaeological evidence of habitation of the territory of the city of San Francisco dates to 3000 BC. Upon independence from Spain in 1821, the became part of Mexico. Under Mexican rule, the system gradually ended, and its lands became privatized. In 1835, Englishman William Richardson erected the first independent homestead, together with Alcalde Francisco de Haro, he laid out a street plan for the expanded settlement, and the town, named Yerba Buena, began to attract American settlers. Commodore John D. Sloat claimed California for the United States on July 7,1846, during the Mexican–American War, montgomery arrived to claim Yerba Buena two days later. Yerba Buena was renamed San Francisco on January 30 of the next year, despite its attractive location as a port and naval base, San Francisco was still a small settlement with inhospitable geography. The California Gold Rush brought a flood of treasure seekers, with their sourdough bread in tow, prospectors accumulated in San Francisco over rival Benicia, raising the population from 1,000 in 1848 to 25,000 by December 1849. The promise of fabulous riches was so strong that crews on arriving vessels deserted and rushed off to the gold fields, leaving behind a forest of masts in San Francisco harbor. Some of these approximately 500 abandoned ships were used at times as storeships, saloons and hotels, many were left to rot, by 1851 the harbor was extended out into the bay by wharves while buildings were erected on piles among the ships. By 1870 Yerba Buena Cove had been filled to create new land, buried ships are occasionally exposed when foundations are dug for new buildings. California was quickly granted statehood in 1850 and the U. S. military built Fort Point at the Golden Gate, silver discoveries, including the Comstock Lode in Nevada in 1859, further drove rapid population growth. With hordes of fortune seekers streaming through the city, lawlessness was common, and the Barbary Coast section of town gained notoriety as a haven for criminals, prostitution, entrepreneurs sought to capitalize on the wealth generated by the Gold Rush

United States Seventh Fleet
–
The Seventh Fleet is a numbered fleet of the United States Navy. Fleet Activities Yokosuka, in Yokosuka, Japan, with units based in Japan. It is part of the United States Pacific Fleet, at present, it is the largest of the forward-deployed U. S. fleets, with 60 to 70 ships,300 aircraft and 40,000 Navy and Marine Corps personnel. In 1994, 7th Fleet was assigned the responsibility as Commander. The Seventh Fleet was formed on 15 March 1943 in Brisbane, Australia, during the Second World War and it served in the South West Pacific Area under General Douglas MacArthur. The Seventh Fleet commander also served as commander of Allied naval forces in the SWPA, most of the ships of the Royal Australian Navy were also part of the fleet from 1943 to 1945 as part of Task Force 74. The Seventh Fleet—under Admiral Thomas C, kinkaid—formed a large part of the Allied forces at the Battle of Leyte Gulf, the largest naval battle in history. After the end of the war, the 7th Fleet moved its headquarters to Qingdao, after the war, on 1 January 1947, the Fleets name was changed to Naval Forces Western Pacific. In late 1948, the Fleet moved its base of operations to the Philippines, where the Navy, following the war, had developed new facilities at Subic Bay. Peacetime operations of the Seventh Fleet were under the control of Commander in Chief Pacific Fleet, on 19 August 1949 the force was designated as United States Seventh Task Fleet. On 11 February 1950, just prior to the outbreak of the Korean War, the force assumed the name United States Seventh Fleet, Seventh Fleet units participated in all major operations of the Korean and Vietnamese Wars. The first Navy jet aircraft used in combat was launched from a Task Force 77 aircraft carrier on 3 July 1950, the landings at Inchon, Korea were conducted by Seventh Fleet amphibious ships. The battleships Iowa, New Jersey, Missouri and Wisconsin all served as flagships for Commander, Seventh Fleet during the Korean War. Over the next decade the Seventh Fleet responded to numerous crisis situations including contingency operations conducted in Laos in 1959, during September 1959, in the autumn of 1960, and again in January 1961, the Seventh Fleet deployed multiship carrier task forces into the South China Sea. Once again the fleet moved into Southeast Asian waters, by the end of April 1961, most of the Seventh Fleet was deployed off the Indochinese Peninsula preparing to initiate operations into Laos. At the same time, shorebased air patrol squadrons and another three Marine battalion landing teams stood ready in Okinawa and the Philippines to support the afloat force, the contending Laotian factions concluded a cease-fire on 8 May 1961, but it lasted only a year. In June 1963 the Seventh Fleet held Flagpole 63, a joint naval exercise with the Republic of Korea, Seventh Fleet represented the first official entrance of the United States into the Vietnam War, with the Gulf of Tonkin incident. Between 1950 and 1970, the U. S, Seventh Fleet was known by the tongue-in-cheek nickname Tonkin Gulf Yacht Club since most of the fleets operations were conducted from the Tonkin Gulf at the time

United Nations
–
The United Nations is an intergovernmental organization to promote international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict, at its founding, the UN had 51 member states, there are now 193. The headquarters of the UN is in Manhattan, New York City, further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states, the UNs mission to preserve world peace was complicated in its early decades by the Cold War between the US and Soviet Union and their respective allies. The organization participated in actions in Korea and the Congo. After the end of the Cold War, the UN took on major military, the UN has six principal organs, the General Assembly, the Security Council, the Economic and Social Council, the Secretariat, the International Court of Justice, and the UN Trusteeship Council. UN System agencies include the World Bank Group, the World Health Organization, the World Food Programme, UNESCO, the UNs most prominent officer is the Secretary-General, an office held by Portuguese António Guterres since 2017. Non-governmental organizations may be granted consultative status with ECOSOC and other agencies to participate in the UNs work, the organization won the Nobel Peace Prize in 2001, and a number of its officers and agencies have also been awarded the prize. Other evaluations of the UNs effectiveness have been mixed, some commentators believe the organization to be an important force for peace and human development, while others have called the organization ineffective, corrupt, or biased. Following the catastrophic loss of life in the First World War, the earliest concrete plan for a new world organization began under the aegis of the US State Department in 1939. It incorporated Soviet suggestions, but left no role for France, four Policemen was coined to refer to four major Allied countries, United States, United Kingdom, Soviet Union, and China, which emerged in the Declaration by United Nations. Roosevelt first coined the term United Nations to describe the Allied countries, the term United Nations was first officially used when 26 governments signed this Declaration. One major change from the Atlantic Charter was the addition of a provision for religious freedom, by 1 March 1945,21 additional states had signed. Each Government pledges itself to cooperate with the Governments signatory hereto, the foregoing declaration may be adhered to by other nations which are, or which may be, rendering material assistance and contributions in the struggle for victory over Hitlerism. During the war, the United Nations became the term for the Allies. To join, countries had to sign the Declaration and declare war on the Axis, at the later meetings, Lord Halifax deputized for Mr. Eden, Wellington Koo for T. V. Soong, and Mr Gromyko for Mr. Molotov. The first meetings of the General Assembly, with 51 nations represented, the General Assembly selected New York City as the site for the headquarters of the UN, and the facility was completed in 1952. Its site—like UN headquarters buildings in Geneva, Vienna, and Nairobi—is designated as international territory, the Norwegian Foreign Minister, Trygve Lie, was elected as the first UN Secretary-General

Naval Station Pearl Harbor
–
Naval Station Pearl Harbor is a U. S. naval base adjacent to Honolulu, in the U. S. state of Hawaii. In 2010, along with the United States Air Forces Hickam Air Force Base, Pearl Harbor is the headquarters of the United States Pacific Fleet. The attack on Pearl Harbor by the Empire of Japan on Sunday,7 December 1941 brought the United States into World War II, Naval Station Pearl Harbor provides berthing and shore side support to surface ships and submarines, as well as maintenance and training. Pearl Harbor can accommodate the largest ships in the fleet, to dry dock services. Housing, personnel, and family support are provided and are an integral part of the shore side activities. Because Pearl Harbor is the only intermediate maintenance facility for submarines in the Middle Pacific, the Naval Computer and Telecommunications Area Master Station, Pacific, Wahiawa, Hawaii is the worlds largest communication station. The headquarters site of this command is located in the central section of the island of Oahu. Following the annexation of Hawaii, Pearl Harbor was refitted to allow for more navy ships, in May 1899, Commander John F. Merry was made naval representative with authority to business for the Navy Department. He immediately assumed control of the Coal Depot and its equipment, to supplement his facilities, he was assigned the Navy tug Iroquois and two coal barges. Inquiries that commenced in June culminated in the establishment of the Naval Station, on 2 February 1900, this title was changed to Naval Station, Hawaii. The creation of the Naval Station allowed the Navy Department to explore territorial outposts, in October 1899, Nero and Iroquois made extensive surveys and sounding of the waterways to Midway and Guam. One of the reasons for these explorations was to select a possible route to Luzon. A coal famine and an outbreak of the plague were the only two incidents that hindered the Commandant from fulfilling his duties. Because of the coal shortage in September 1899, the Commandant sold coal to the Oahu Railway and Land Company. Approximately 61 deaths were recorded in Honolulu for this period, work was consequently delayed on nascent Navy projects in Honolulu Harbor. From 1900 to 1908, the Navy devoted its time to improving the facilities of the 85 acres that constituted the naval reservation in Honolulu, under the Appropriation Act of 3 March 1901, this tract of land was improved with the erection of additional sheds and housing. Improvements included a shop, smithery and foundry, Commandants house and stables, cottage for the watchman, fencing, 10-ton wharf crane

Pearl Harbor
–
Pearl Harbor is a lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. Much of the harbor and surrounding lands is a United States Navy deep-water naval base and it is also the headquarters of the United States Pacific Fleet. The U. S. government first obtained exclusive use of the inlet, the attack on Pearl Harbor by the Empire of Japan on December 7,1941, was the immediate cause of the United States entry into World War II. Pearl Harbor was originally a shallow embayment called Wai Momi or Puʻuloa by the Hawaiians. Puʻuloa was regarded as the home of the goddess, Kaʻahupahau. Making due allowance for legendary amplification, the estuary already had an outlet for its waters where the present gap is, during the early 19th century, Pearl Harbor was not used for large ships due to its shallow entrance. The interest of United States in the Hawaiian Islands grew as a result of its whaling, shipping and trading activity in the Pacific. As early as 1820, an Agent of the United States for Commerce and these commercial ties to the American continent were accompanied by the work of the American Board of Commissioners for Foreign Missions. American missionaries and their families became a part of the Hawaiian political body. Throughout the 1820s and 1830s, many American warships visited Honolulu, in most cases, the commanding officers carried letters from the U. S. Government giving advice on governmental affairs and of the relations of the island nation with foreign powers. In 1841, the newspaper Polynesian, printed in Honolulu, advocated that the U. S. establish a base in Hawaii for protection of American citizens engaged in the whaling industry. The British Hawaiian Minister of Foreign Affairs Robert Crichton Wyllie, remarked in 1840 that and my opinion is that the tide of events rushes on to annexation to the United States. In 1865, the North Pacific Squadron was formed to embrace the western coast, lackawanna in the following year was assigned to cruise among the islands, a locality of great and increasing interest and importance. This vessel surveyed the Northwestern Hawaiian Islands toward Japan, as a result, the United States claimed Midway Island. The Secretary of the Navy was able to write in his report of 1868. This increased activity caused the permanent assignment of at least one warship to Hawaiian waters and it also praised Midway Island as possessing a harbor surpassing Honolulus. In the following year, Congress approved an appropriation of $50,000 on March 1,1869, after 1868, when the Commander of the Pacific Fleet visited the islands to look after American interests, naval officers played an important role in internal affairs. They served as arbitrators in disputes, negotiators of trade agreements and defenders of law

Project Gemini
–
Project Gemini was NASAs second human spaceflight program. Conducted between projects Mercury and Apollo, Gemini started in 1961 and concluded in 1966, the Gemini spacecraft carried a two-astronaut crew. Ten Gemini crews flew low Earth orbit missions between 1965 and 1966 putting the United States in the lead during the Cold War Space Race against the Soviet Union, geminis objective was the development of space travel techniques to support the Apollo mission to land astronauts on the Moon. With these new techniques proven by Gemini, Apollo could pursue its mission without doing these fundamental exploratory operations. All Gemini flights were launched from Launch Complex 19 at Cape Kennedy Air Force Station in Florida and their launch vehicle was the Gemini–Titan II, a modified Intercontinental Ballistic Missile. Gemini was the first program to use the newly built Mission Control Center at the Houston Manned Spacecraft Center for flight control, the astronaut corps that supported Project Gemini included the Mercury Seven, The New Nine, and the 1963 astronaut class. During the program, three died in air crashes during training, including the prime crew for Gemini 9. This mission was performed by the crew, the only time that had happened in NASAs history to date. Gemini was robust enough that the United States Air Force planned to use it for the Manned Orbital Laboratory program, geminis chief designer, Jim Chamberlin, also made detailed plans for cislunar and lunar landing missions in late 1961. He believed Gemini could perform lunar operations before Project Apollo, NASAs administration did not approve those plans. In 1969, McDonnell-Douglas proposed a Big Gemini that could have used to shuttle up to 12 astronauts to the planned space stations in the Apollo Applications Project. The only AAP project funded was Skylab – which used existing spacecraft and he presented two initial versions of Gemini at a NASA retreat at Wallops Island in March 1961. Scale models of Mercury Mark II were shown in July 1961 at McDonnell Aircraft Corporations offices in St. Louis, NASA approved Project Gemini on December 7,1961. The McDonnell corporation was contracted to build it on December 22,1961, when it was publicly announced on January 3,1962, it was formally re-christened Project Gemini. Gemini in Latin means twins or double, which reflected that the spacecraft would hold two astronauts, Gemini is also the name of the third constellation of the Zodiac and its twin stars, Castor and Pollux. He was previously the chief aerodynamicist on Avro Canadas Avro Arrow fighter interceptor program, Chamberlin joined NASA along with 25 senior Avro engineers after cancellation of the Arrow program, and became head of the U. S. Space Task Group’s engineering division in charge of Gemini, the prime contractor was McDonnell Aircraft Corporation, which was also the prime contractor for the Project Mercury capsule. Astronaut Gus Grissom was heavily involved in the development and design of the Gemini spacecraft, the Gemini program was managed by the Manned Spacecraft Center, located in Houston, Texas, under direction of the Office of Manned Space Flight, NASA Headquarters, Washington, D. C

Market Time
–
Operation Market Time was the United States Navy and South Vietnam’s effort to stop troops and supplies from flowing by sea from North Vietnam to South Vietnam during the Vietnam War. Also participating in Operation Market Time were United States Coast Guard Squadron One, Operation Market Time was one of six Navy duties begun after the Tonkin Gulf Incident, along with Operation Sea Dragon, Operation Sealords, Yankee Station, PIRAZ, and naval gunfire support. This became known as the Vung Ro Bay Incident, Operation Market Time was established by the United States Joint Chiefs of Staff at the request of General William C. Westmoreland, commanding general of Military Assistance Command Vietnam and he requested that the U. S. Navy establish a naval blockade of the vast South Vietnam coastline against North Vietnamese gun-running trawlers. The trawlers, usually 100-foot-long Chinese-built steel-hulled coastal freighters, could carry several tons of arms, if successful, the ships would off load their cargoes to waiting Việt Cộng or North Vietnamese forces. On 16 April 1965 United States Secretary of the Navy Paul Nitze requested Coast Guard assistance with Market Time, at Subic Bay each cutter was armed with an 81 mm mortar and five.50 caliber M2 Browning machine guns. Coast Guard Squadron One was organized into Division Eleven with eight cutters, Division Twelve sailed on 15 July 1965 and arrived at Đà Nẵng on 20 July. Division Eleven sailed on 20 July and arrived at An Thoi on 31 July, nine additional cutters formed Division Thirteen at Vũng Tàu in early 1966. Each cutter with a crew would spend four days on patrol followed by two days alongside a support ship. All 26 cutters were turned over to South Vietnamese crews between 16 May 1969 and 15 August 1970, the objective of Operation Market Time focused on preventing communist ships from infiltrating the South Vietnamese coast in order to resupply North Vietnamese Army and Viet Cong forces. The operation was placed under the control of the Vietnam Patrol Force, however command shifted to the Commander, Naval Forces Vietnam on 31 July 1965. Operation Market Time was originally planned to acquire 54 Swift boats, seaplane tenders USS Currituck, USS Pine Island, and USS Salisbury Sound served as flagships for Market Time. U. S. Navy Martin P-5 Marlin seaplane patrol squadrons, destroyers, ocean minesweepers, PCFs, also playing a key role in the interdictions were the Navy’s patrol gunboats. The PG was uniquely suited for the job because of its ability to go from standard diesel propulsion to gas turbine propulsion in a matter of a few minutes, the lightweight aluminum and fiberglass ships were not only fast but highly maneuverable because of their variable-pitch propellers. Most of the ships operated in the waters from the Cambodian border around the south tip of Vietnam up north to Đà Nẵng. Supply ships from the Service Force, such as oilers, would bring mail, movies, a significant action of Market Time occurred on 1 March 1968, when the North Vietnamese attempted a coordinated infiltration of four gun-running trawlers. This incident of a blue-on-blue engagement killed two members of the crew and wounded nearly everyone on board. To stop these infiltrations, Market Time was set up as an effort of long range patrol aircraft for broad reconnaissance

Naval gunfire support
–
Naval gunfire support is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of a number of disciplines encompassed by the term Naval Fires, modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched Land-attack missiles. Shipborne guns have used against shore defences since the early days of naval warfare. NGFS is classified into two types, direct fire, where the ship has line of sight with the target, and indirect fire, an early use of shore bombardment was during the Siege of Calais in 1347 when Edward III of England deployed ships carrying Bombardes and other artillery. An early type of vessel designed for the purpose of shore bombardment was the Bomb vessel and these were small ships whose main armament was one or two large mortars, that fired explosive shells at a high angle. They were typically poor sailing craft that were of limited use outside their specialized role, however, small vessels armed with large mortars saw use as late as the American Civil War, when the Union Navy used them in several attacks on coastal fortifications. During the 18th century, another class of vessel known as Floating battery were devised for shore bombardment. An early use of them was by the French and Spanish during the Great Siege of Gibraltar, during the Napoleonic Wars, the Royal Navy commissioned several vessels of the Musquito-class floating battery and Firm-class floating battery. These carried either Naval long guns or carronades, Floating batteries were used by both the French and British during the Crimean War, and by both sides during the American Civil War. In the Aegean the enemy defences were fairly unsophisticated, however. Here, the fortresses outline tended to blend into the hillside making identification difficult, mobile howitzers on the plateau presented even greater problems, since these were higher still, and being completely shielded from view proved almost impervious to naval bombardment. For RN ships bombarding German targets along the Belgian Coast the situation was different from the autumn of 1915 until the enemy withdrawal in October 1918. For this role, the Royal Navy frequently made use of specially designed vessels known as monitors and they carried extremely heavy armament for their size, often a single turret from a decommissioned battleship. A broad beamed hull designed for stability, and a draft to allow close approach to the shore however made them slow vessels that were unsuitable for naval combat. Two Lord Clive-class monitors were fitted with BL18 inch Mk I naval guns, the Germans constructed an extensive, well-equipped and well-coordinated system of gun-batteries etc. to defend the coast—and especially the ports of Ostend and Zeebrugge. This was a significant advance, which basically established a firm foundation for Naval Bombardment as practiced by the RN. In 1939, therefore, the RN was quite prepared for this particular aspect of joint warfare. Battleships, cruisers and destroyers would pound shore installations, sometimes for days, in the hope of reducing fortifications, obsolete battleships unfit for combat against other ships were often used as floating gun platforms expressly for this purpose

Aircraft carrier
–
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Aircraft carriers are expensive to build and are critical assets, there is no single definition of an aircraft carrier, and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, Aircraft carriers may be classified according to the type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope, former head of the Royal Navy, has said, To put it simply, as of April 2017, there are 37 active aircraft carriers in the world within twelve navies. The United States Navy has 10 large nuclear-powered fleet carriers, the largest carriers in the world, the Royal Navy of Great Britain is building two 280-m / 920-ft carriers, the Queen Elizabeth, and the Prince of Wales scheduled to go into service in 2020-2023. These are the largest carriers capable of fast speeds, by comparison, escort carriers were developed to provide defense for convoys of ships. They were smaller and slower with lower numbers of aircraft carried, most were built from mercantile hulls or, in the case of merchant aircraft carriers, were bulk cargo ships with a flight deck added on top. Light aircraft carriers were fast enough to operate with the main fleet, three nations currently operate carriers of this type, ten by the United States, and one each by France and Brazil for a total of twelve in service. Short take-off but arrested-recovery, these carriers are generally limited to carrying lighter fixed-wing aircraft with more limited payloads, currently, Russia, China, and India possess commissioned carriers of this type. Short take-off vertical-landing, limited to carrying STOVL aircraft and this type of aircraft carrier is currently in service with Italy. Some also count the nine US amphibious assault ships in their secondary light carrier role boosting the total to thirteen. Helicopter carrier, Helicopter carriers have an appearance to other aircraft carriers. Some are designed for addition of, or may include, a ski jump ramp allowing for STOVL operations or may have a ski jump installed before retirement of STOVL aircraft. In the past, some conventional carriers were converted and called commando carriers by the Royal Navy, some helicopter carriers with a resistant flight surface can operate STOVL jets. Currently the majority of carriers, but not all, are classified as amphibious assault ships. The US has nine of this type, France and Japan three, Australia two, the UK one, the Republic of Korea one and Spain one, the US and Spains amphibious assault ships operate STOVL jets in normal deployment. Supercarrier Fleet carrier Light aircraft carrier Escort carrier Several systems of identification symbol for aircraft carriers, two months later, on 18 January 1911, Ely landed his Curtiss pusher airplane on a platform on the armored cruiser USS Pennsylvania anchored in San Francisco Bay

Gulf of Tonkin
–
The Gulf of Tonkin is a body of water located off the coast of northern Vietnam and southern China. It is an arm of the South China Sea. The Gulf is defined in the west by the coastline of Vietnam, in the north by Chinas Guangxi province. The bays Vietnamese and Chinese names – Vịnh Bắc Bộ and Běibù Wān, the name Tonkin, written 東京 in Hán-Nôm characters and Đông Kinh in the Vietnamese alphabet, means eastern capital, and is the former toponym for Hanoi, the present capital of Vietnam. It should not to be confused with Tokyo, which is also written 東京, during Vietnams French colonial era, Tonkin was used to refer to the north of the country. On 2 August 1964, United States President Lyndon B. Johnson claimed that North Vietnamese forces had twice attacked American destroyers in the Gulf of Tonkin. Known today as the Gulf of Tonkin Incident, this event spawned the Gulf of Tonkin Resolution of 7 August 1964 and it furthermore foreshadowed the major escalation of the Vietnam War in South Vietnam, which began with the landing of US regular combat troops at Da Nang in 1965.

Taiwan
–
Taiwan, officially the Republic of China, is a state in East Asia. Neighbours include China to the west, Japan to the northeast, Taiwan is the most populous state that is not a member of the United Nations, and the one with the largest economy. The island of Taiwan, also known as Formosa, was inhabited by Taiwanese aborigines before the 17th century. After a brief rule by the Kingdom of Tungning, the island was annexed by the Qing dynasty, the Qing ceded Taiwan to Japan in 1895 after the Sino-Japanese War. While Taiwan was under Japanese rule, the Republic of China was established on the mainland in 1912 after the fall of the Qing dynasty, following the Japanese surrender to the Allies in 1945, the ROC took control of Taiwan. However, the resumption of the Chinese Civil War led to the ROCs loss of the mainland to the Communists, and the flight of the ROC government to Taiwan in 1949. As a founding member of the United Nations, the ROC continued to represent China at the United Nations until 1971, in the early 1960s, Taiwan entered a period of rapid economic growth and industrialization, creating a stable industrial economy. In the 1980s and early 1990s, it changed from a one-party military dictatorship dominated by the Kuomintang to a multi-party democracy with universal suffrage, Taiwan is the 22nd-largest economy in the world, and its high-tech industry plays a key role in the global economy. It is ranked highly in terms of freedom of the press, health care, public education, economic freedom, the PRC has consistently claimed sovereignty over Taiwan and asserted the ROC is no longer in legitimate existence. Under its One-China Policy the PRC refused diplomatic relations with any country that recognizes the ROC, the PRC has threatened the use of military force in response to any formal declaration of independence by Taiwan or if PRC leaders decide that peaceful unification is no longer possible. There are various names for the island of Taiwan in use today, the former name Formosa dates from 1542, when Portuguese sailors sighted the main island of Taiwan and named it Ilha Formosa, which means beautiful island. The name Formosa eventually replaced all others in European literature and was in use in English in the early 20th century. This name was adopted into the Chinese vernacular as the name of the sandbar. The modern word Taiwan is derived from this usage, which is seen in forms in Chinese historical records. Use of the current Chinese name was formalized as early as 1684 with the establishment of Taiwan Prefecture, through its rapid development, the entire Formosan mainland eventually became known as Taiwan. The official name of the state is the Republic of China and it was a member of the United Nations representing China until 1971, when it lost its seat to the Peoples Republic of China. Over subsequent decades, the Republic of China has become known as Taiwan. In some contexts, especially ones from the ROC government

President of the United States
–
The President of the United States is the head of state and head of government of the United States. The president directs the executive branch of the government and is the commander-in-chief of the United States Armed Forces. The president is considered to be one of the worlds most powerful political figures, the role includes being the commander-in-chief of the worlds most expensive military with the second largest nuclear arsenal and leading the nation with the largest economy by nominal GDP. The office of President holds significant hard and soft power both in the United States and abroad, Constitution vests the executive power of the United States in the president. The president is empowered to grant federal pardons and reprieves. The president is responsible for dictating the legislative agenda of the party to which the president is a member. The president also directs the foreign and domestic policy of the United States, since the office of President was established in 1789, its power has grown substantially, as has the power of the federal government as a whole. However, nine vice presidents have assumed the presidency without having elected to the office. The Twenty-second Amendment prohibits anyone from being elected president for a third term, in all,44 individuals have served 45 presidencies spanning 57 full four-year terms. On January 20,2017, Donald Trump was sworn in as the 45th, in 1776, the Thirteen Colonies, acting through the Second Continental Congress, declared political independence from Great Britain during the American Revolution. The new states, though independent of each other as nation states, desiring to avoid anything that remotely resembled a monarchy, Congress negotiated the Articles of Confederation to establish a weak alliance between the states. Out from under any monarchy, the states assigned some formerly royal prerogatives to Congress, only after all the states agreed to a resolution settling competing western land claims did the Articles take effect on March 1,1781, when Maryland became the final state to ratify them. In 1783, the Treaty of Paris secured independence for each of the former colonies, with peace at hand, the states each turned toward their own internal affairs. Prospects for the convention appeared bleak until James Madison and Edmund Randolph succeeded in securing George Washingtons attendance to Philadelphia as a delegate for Virginia. It was through the negotiations at Philadelphia that the presidency framed in the U. S. The first power the Constitution confers upon the president is the veto, the Presentment Clause requires any bill passed by Congress to be presented to the president before it can become law. Once the legislation has been presented, the president has three options, Sign the legislation, the bill becomes law. Veto the legislation and return it to Congress, expressing any objections, in this instance, the president neither signs nor vetoes the legislation
