Victory ship
–
The Victory ship was a class of cargo ship produced in large numbers by North American shipyards during World War II to replace losses caused by German submarines. A total of 531 Victory ships were built, one of the first acts of the United States War Shipping Administration upon its formation in February 1942 was to commission the design of what came to be known as the Victory class. The design was an enhancement of the Liberty ship, which had successfully produced in extraordinary numbers. Victory ships were larger than Liberty ships,14 feet longer at 455 feet,6 feet wider at 62 ft. Displacement was up just under 1,000 tons, to 15,200, with a raised forecastle and a more sophisticated hull shape to help achieve the higher speed, they had a quite different appearance from Liberty ships. To make them vulnerable to U-boat attacks, Victory ships made 15 to 17 knots,4 to 6 knots faster than the Libertys. The extra speed was achieved through more modern, efficient engines, most used steam turbines, which had been in short supply earlier in the war and reserved for warships. All were oil-fired, but for a handful of Canadian vessels completed with both coal bunkers and oil tanks, another improvement was electrically powered auxiliary equipment, rather than steam-driven machinery. To prevent the hull fractures that a few Liberty ships developed and these were manned by United States Navy Armed Guard personnel. The VC2-S-AP5 Haskell-class attack transports were armed with the 5-inch stern gun, one quad 40 mm Bofors cannon, four dual 40 mm Bofors cannon, the Haskells were operated and crewed exclusively by U. S. Navy personnel. The Victory ship was noted for good proportion of cubic between holds for a ship of its day. A Victory ships cargo hold one, two and five hatches are a single rigged with a capacity of 70,400,76,700, and 69,500 bale cubic feet respectively. Victory ships hold three and four hatches are double rigged with a capacity of 136,100 and 100,300 bale cubic feet respectively. Victory ship have built in mast, booms and derrick cranes, the first vessel was SS United Victory launched at Oregon Shipbuilding Corporation on 12 January 1944 and completed on 28 February 1944, making her maiden voyage a month later. American vessels frequently had a name incorporating the word Victory, the British and Canadians used Fort and Park respectively. Although initial deliveries were slow—only 15 had been delivered by May 1944—by the end of the war 531 had been constructed, because the Atlantic battle had been won by the time that the first of the Victory ships appeared none were sunk by U-boats. Three were sunk by Japanese kamikaze attack in April of 1945, many Victory ships were converted to troopship to bring US soldiers home at the end of World War II as part of Operation Magic Carpet. A total of 97 Victory ships were converted to carry up to 1,600 soldiers

War Shipping Administration
–
The War Shipping Administration was a World War II emergency war agency of the US government, tasked to purchase and operate the civilian shipping tonnage the US needed for fighting the war. Both shipbuilding under the Maritime Commission and ship allocation under the WSA to Army, land who continued as head of the Maritime Commission while also heading the WSA. A shortage of vessels further complicated by requirements to take out of service for conversion and armament was of concern at the highest levels. Harry Hopkins reporting directly to the President, differences between the organizations and lack of decisive authority short of the President limited the boards effectiveness. Upon establishment of the WSA the Strategic Shipping Board continued in existence in a diminished role under the Joint Chiefs of Staff. On February 7,1942, the WSA was established by President Franklin Delano Roosevelts Executive Order No.9054, February 7,1942 as the U. S. had entered the war. The WSA was administratively split off from the United States Maritime Commission, established in 1936 and those included the production of Liberty ships and Victory ships among other types. The U. S. fleet expanded to some 3,500 dry cargo vessels, on a practical level The Maritime Commission and the WSA worked closely together under the administration of Vice Admiral Emory S. Land at the head of each and it became apparent immediately when this Nation entered the war that a special agency to deal with the operational problems peculiar to war was necessary to supplement the Maritime Commission. Thus WSA became the Governments ship operating agency and the Maritime Commission its shipbuilding agency, under that authority cargo hulls were allocated to either commerce, Army or Navy. Many of the Armys ships and Naval transports were allocated by WSA, WSA, through its agents, directly operated ships in support of the services and civilian requirements. After the war, WSA vessels were used to home the huge number of armed personnel overseas, as part of Operation Magic Carpet. Over 3,500,000 men were brought home from overseas areas by December 1,1945, on September 1,1946, the WSA functions were returned to the Maritime Commission.

Bethlehem Shipbuilding Corporation
–
Bethlehem Steel Corporation Shipbuilding Division was created in 1905 when Bethlehem Steel Corporation acquired the San Francisco shipyard Union Iron Works in 1905. In 1917 it was incorporated as Bethlehem Shipbuilding Corporation, Limited, headquarters were in Quincy, Massachusetts, after acquiring Fore River Shipyard in 1913 and later in Sparrows Point, Maryland, in 1964. In 1940, it was number 1 of the Big 3 U. S. shipbuilders who could build any ship, newport News Shipbuilding & Drydock and New York Shipbuilding Corporation were #2 and #3. Bethlehem had 4 yards in early 1940, Fore River, Sparrows Point, San Francisco, Bethlehem expanded during World War II as a result of the Emergency Shipbuilding program administered under the United States Maritime Commission. The Quincy yard was sold to General Dynamics Corporation in the mid-1960s, Bethlehem Steel ceased shipbuilding activities in 1997 in an attempt to preserve its core steel making operations. The following shipyards were owned by Bethlehem and they are listed in order of acquisition. Beaumont, Texas The Beaumont Yard was one of the sources of offshore drilling rigs built in the United States with seventy–two offshore rigs built at the yard. Seventy-one Type C1 ships were built during World War II by Pennsylvania Shipyards, Shipbuilding Division Photographs, circa 1900-1945 at San Francisco Maritime National Historical Park

Baltimore, Maryland
–
Baltimore is the largest city in the U. S. state of Maryland, and the 29th-most populous city in the country. It was established by the Constitution of Maryland and is not part of any county, thus, it is the largest independent city in the United States, with a population of 621,849 as of 2015. As of 2010, the population of the Baltimore Metropolitan Area was 2.7 million, founded in 1729, Baltimore is the second largest seaport in the Mid-Atlantic. Baltimores Inner Harbor was once the leading port of entry for immigrants to the United States. With hundreds of identified districts, Baltimore has been dubbed a city of neighborhoods, in the War of 1812, Francis Scott Key wrote The Star-Spangled Banner, later the American national anthem, in Baltimore. More than 65,000 properties, or roughly one in three buildings in the city, are listed on the National Register, more than any city in the nation. The city has 289 properties listed on the National Register of Historic Places, the historical records of the government of Baltimore are located at the Baltimore City Archives. The city is named after Cecil Calvert, second Lord Baltimore, of the Irish House of Lords, Baltimore Manor was the name of the estate in County Longford on which the Calvert family lived in Ireland. Baltimore is an anglicization of the Irish name Baile an Tí Mhóir, in 1608, Captain John Smith traveled 210 miles from Jamestown to the uppermost Chesapeake Bay, leading the first European expedition to the Patapsco River. The name Patapsco is derived from pota-psk-ut, which translates to backwater or tide covered with froth in Algonquian dialect, a quarter century after John Smiths voyage, English colonists began to settle in Maryland. The area constituting the modern City of Baltimore and its area was first settled by David Jones in 1661. He claimed the area today as Harbor East on the east bank of the Jones Falls stream. In the early 1600s, the immediate Baltimore vicinity was populated, if at all. The Baltimore area had been inhabited by Native Americans since at least the 10th millennium BC, one Paleo-Indian site and several Archaic period and Woodland period archaeological sites have been identified in Baltimore, including four from the Late Woodland period. During the Late Woodland period, the culture that is called the Potomac Creek complex resided in the area from Baltimore to the Rappahannock River in Virginia. It was located on the Bush River on land that in 1773 became part of Harford County, in 1674, the General Assembly passed An Act for erecting a Court-house and Prison in each County within this Province. The site of the house and jail for Baltimore County was evidently Old Baltimore near the Bush River. In 1683, the General Assembly passed An Act for Advancement of Trade to establish towns, ports, one of the towns established by the act in Baltimore County was on Bush River, on Town Land, near the Court-House

Horsepower
–
Horsepower is a unit of measurement of power. There are many different standards and types of horsepower, two common definitions being used today are the mechanical horsepower, which is approximately 746 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of engines with the power of draft horses. It was later expanded to include the power of other types of piston engines, as well as turbines, electric motors. The definition of the unit varied among geographical regions, most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on January 1,2010, units called horsepower have differing definitions, The mechanical horsepower, also known as imperial horsepower equals approximately 745.7 watts. It was defined originally as exactly 550 foot-pounds per second [745.7 N. m/s), the metric horsepower equals approximately 735.5 watts. It was defined originally as 75 kgf-m per second is approximately equivalent to 735.5 watts, the Pferdestärke PS is a name for a group of similar power measurements used in Germany around the end of the 19th century, all of about one metric horsepower in size. The boiler horsepower equals 9809.5 watts and it was used for rating steam boilers and is equivalent to 34.5 pounds of water evaporated per hour at 212 degrees Fahrenheit. One horsepower for rating electric motors is equal to 746 watts, one horsepower for rating Continental European electric motors is equal to 735 watts. Continental European electric motors used to have dual ratings, one British Royal Automobile Club horsepower can equal a range of values based on estimates of several engine dimensions. It is one of the tax horsepower systems adopted around Europe, the development of the steam engine provided a reason to compare the output of horses with that of the engines that could replace them. He had previously agreed to take royalties of one third of the savings in coal from the older Newcomen steam engines and this royalty scheme did not work with customers who did not have existing steam engines but used horses instead. Watt determined that a horse could turn a mill wheel 144 times in an hour, the wheel was 12 feet in radius, therefore, the horse travelled 2.4 × 2π ×12 feet in one minute. Watt judged that the horse could pull with a force of 180 pounds-force. So, P = W t = F d t =180 l b f ×2.4 ×2 π ×12 f t 1 m i n =32,572 f t ⋅ l b f m i n. Watt defined and calculated the horsepower as 32,572 ft·lbf/min, Watt determined that a pony could lift an average 220 lbf 100 ft per minute over a four-hour working shift. Watt then judged a horse was 50% more powerful than a pony, engineering in History recounts that John Smeaton initially estimated that a horse could produce 22,916 foot-pounds per minute

Steam turbine
–
A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884, in 1551, Taqi al-Din in Ottoman Egypt described a steam turbine with the practical application of rotating a spit. Steam turbines were described by the Italian Giovanni Branca and John Wilkins in England. The devices described by Taqi al-Din and Wilkins are today known as steam jacks, in 1672 an impulse steam turbine driven car was designed by Ferdinand Verbiest. A more modern version of car was produced some time in the late 18th century by an unknown German mechanic. The modern steam turbine was invented in 1884 by Sir Charles Parsons, the invention of Parsons steam turbine made cheap and plentiful electricity possible and revolutionized marine transport and naval warfare. Parsons design was a reaction type and his patent was licensed and the turbine scaled-up shortly after by an American, George Westinghouse. The Parsons turbine also turned out to be easy to scale up. Parsons had the satisfaction of seeing his invention adopted for all major world power stations, a number of other variations of turbines have been developed that work effectively with steam. The de Laval turbine accelerated the steam to full speed before running it against a turbine blade, De Lavals impulse turbine is simpler, less expensive and does not need to be pressure-proof. It can operate with any pressure of steam, but is less efficient. He taught at the École des mines de Saint-Étienne for a decade until 1897, one of the founders of the modern theory of steam and gas turbines was Aurel Stodola, a Slovak physicist and engineer and professor at the Swiss Polytechnical Institute in Zurich. His work Die Dampfturbinen und ihre Aussichten als Wärmekraftmaschinen was published in Berlin in 1903, a further book Dampf und Gas-Turbinen was published in 1922. It was used in John Brown-engined merchant ships and warships, including liners, the present-day manufacturing industry for steam turbines is dominated by Chinese power equipment makers. Other manufacturers with minor market share include Bhel, Siemens, Alstom, GE, Doosan Škoda Power, Mitsubishi Heavy Industries, the consulting firm Frost & Sullivan projects that manufacturing of steam turbines will become more consolidated by 2020 as Chinese power manufacturers win increasing business outside of China. There are several classifications for modern steam turbines, Turbine blades are of two basic types, blades and nozzles. Blades move entirely due to the impact of steam on them and this results in a steam velocity drop and essentially no pressure drop as steam moves through the blades. A turbine composed of alternating with fixed nozzles is called an impulse turbine, Curtis turbine, Rateau turbine

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

3"/50 caliber gun
–
For Army 3-inch gun see 3-inch M1918 gun The 3″/50 caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U. S. Navy and U. S. Coast Guard from 1890 through the 1990s on a variety of combatant and transport ship classes. The US Navys first 3″/50 caliber gun was a model with a projectile velocity of 2,100 feet per second. Low-angle mountings for this gun had a range of 7000 yards at the elevation of 15 degrees. The gun entered service around 1900 with the Bainbridge-class destroyers, and was fitted to Connecticut-class battleships. By World War II these guns were only on a few Coast Guard cutters. These guns fired the same 2,700 feet per second used by the following dual-purpose Marks. These were built-up guns with a tube, partial-length jacket, hoop, dual-purpose 3″/50 caliber guns first entered service in 1915 as a refit to USS Texas, and were subsequently mounted on many types of ships as the need for anti-aircraft protection was recognized. They also replaced the original low-angle 4/50 caliber guns on flush-deck Wickes and these dual-purpose guns were quick-firing, meaning that they used fixed ammunition, with powder case and projectile permanently attached, and handled as a single unit weighing 34 pounds. Maximum range was 14,600 yards at 45 degrees elevation, useful life expectancy was 4300 effective full charges per barrel. The 3/50 caliber gun Marks 17 and 18 was first used as a deck gun on R-class submarines launched in 1918-1919. At the time it was an improvement on the earlier 3/23 caliber gun, after using larger guns on many other submarines, the 3/50 caliber gun Mark 21 was specified as the standard deck gun on the Porpoise- through Gato-class submarines launched in 1935-1942. The small gun was chosen to remove the temptation to engage enemy vessels on the surface. The gun was mounted aft of the conning tower to reduce submerged drag. Wartime experience showed that larger guns were needed and this need was initially met by transferring 4/50 caliber guns from S-class submarines as they were shifted from combat to training roles from late 1942. Later, the 5/25 caliber gun, initially removed from battleships sunk or damaged in the attack on Pearl Harbor and later manufactured in a submarine version, post-war experimentation with an extended range variant was abandoned as shipboard surface-to-air missiles were developed. The United States Navy considered contemporary 5/38 caliber guns and 5″/54 caliber guns more effective against surface targets, the 3″/50 caliber gun was a semiautomatic anti-aircraft weapon with a power driven automatic loader. These monobloc 3″ guns were fitted to both single and twin mountings, the single was to be exchanged for a twin 40 mm antiaircraft gun mount and the twin for a quadruple 40 mm mount

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

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

Emergency Shipbuilding program
–
The Emergency Shipbuilding Program was a United States government effort to quickly build simple cargo ships to carry troops and material to allies and foreign theatres during World War II. Run by the U. S. Maritime Commission, the program built almost 6,000 ships, by the fall of 1940, the British Merchant Navy was being sunk in the Battle of the Atlantic by Germanys U-Boats faster than the United Kingdom could replace them. Led by Sir Arthur Salter, a group of men called the British Merchant Shipping Mission came to North America from the UK to enlist U. S. and Canadian shipbuilders to construct merchant ships. As all existing U. S. shipyards capable to constructing ocean-going merchant ships were occupied by either work of building ships for the U. S. Navy or for the U. S. S. Ship repairer Todd Shipyards which had its headquarters in New York City in league with the shipbuilder Bath Iron Works located in Bath and that yard was to be called the Todd-California Shipbuilding Corp. It was slated to be built on the flats of Richmond on the east side of the Bay. Kaiser, who headed the Kaiser Companies, and John A. McCone, contracts for both yards and the ships was signed on December 20,1940. The first of these vessels, the SS Ocean Vanguard was launched at the Todd-California yard on October 15,1941, immediately the Commission authorized that the two yards building for the British build ships for the U. S. upon completion of their current contracts. S. In this first wave of seven additional yards were added to those in Maine and California. One of the new yards planned for construction was to be in Baltimore and that facility became known as the Bethlehem-Fairfield shipyard for the Fairfield section of Baltimore where it was located. On the West Coast it had yards in San Pedro and San Francisco and that yard was to be called the North Carolina Shipbuilding Company. On the West Coast, one yard was contracted to be built in Los Angeles at Terminal Island and that yard would be called the California Shipbuilding Corporation or CalShip for short. The Kaiser Corporation itself received a contract to build a new yard on the Columbia River at Portland, in 1941, the manufacturers of steam turbines in the U. S. With that, the Liberty ship was adopted as the emergency type to be built. As 1941 progressed, the construction of the emergency yards accelerated rapidly, the ships ordered this second wave included 112 emergency type, the remainder were standard type vessels and tankers. After this time the original Kaiser yard became known as Richmond #1, after the May 27 Declaration of Unlimited National Emergency by the President, the Emergency Program was further expanded in a third wave. To accommodate the addition of ships to be built, additional ways were added to the yards in the program. In total this increase raised the output of all merchant shipbuilders to approximately 500 ships for 1942 and 700 ships in 1943

European Theater of Operations
–
The European Theater of Operations, United States Army was a United States Army formation which directed US Army operations in parts of Europe from 1942 to 1945. It referred to Army Ground Forces, United States Army Air Forces, and Army Service Forces operations north of Italy and it was bordered to the south by the North African Theater of Operations, US Army, which later became the Mediterranean Theater of Operations. As the armies advanced, both these zones and the areas into which they were divided would shift forward to new areas of control. Major General James E. Chaney, an Army Air Corps officer, arrived in the United Kingdom on 18 May 1941, SBOPS also had the role of studying British use of Lend Lease supplies. His formal title was the Special Army Observer in the United Kingdom, after the United States entered the war, SPOBS was succeeded by United States Army Forces in the British Isles, actually SPOBS under a new name. At the time of the ARCADIA Conference, December 1941 – January 1942, daley, and make him in turn responsible to General Chaney, designated as CG, USAFBI. Lt. Gen. John C. H. Lee became Chief, Services of Supply, U. S. Army Forces British Isles, on June 8,1942, the United States Department of War officially established ETOUSA in its place. Its mission was to conduct planning for the retaking of Europe and to exercise administrative. The 133rd Infantry Regiment of the 34th Infantry Division was the first United States Army unit sent to Europe in World War II, the first battalion arrived in Belfast in late January 1942, followed by the rest of the regiment in February. These units were designated as U. S. Army Northern Ireland Forces, the 133rd and 168th Infantry Regiments trained in the peat bogs, and performed border guard patrols between British Northern Ireland and the neutral Irish Free State. The remaining unit of the division, the 135th Infantry Regiment, until SHAEF was operational ETOUSA liaised closely with the British in the planning and organising of Operation Overlord. General Dwight D. Eisenhower had multiple command appointments, he replaced Chaney in late June 1942 and he then relinquished command of ETOUSA to Lt. Gen. Frank M. Andrews in February 1943, who was killed in an air crash in May. He was replaced by Lt. Gen. Jacob L. Devers, in December 1943 it was announced that Eisenhower would be Supreme Allied Commander in Europe. In January 1944 he resumed command of ETOUSA and the month was officially designated as the Supreme Commander of the Allied Expeditionary Forces. He served in a role until the end of hostilities in Europe in May 1945. From February 1944, SHAEF was the command and ETOUSA administrative command. Some units were transferred between operational commands and administrative commands at different times, by the end of 1944, Eisenhower, through SHAEF, commanded three powerful Allied army groups. The British 21st Army Group and French elements of the 6th Army Group were not part of ETOUSA, the ETOUSA planning staff in London was usually referred to by its Army Post Office number, APO887

Atlantic Ocean
–
The Atlantic Ocean is the second largest of the worlds oceans with a total area of about 106,460,000 square kilometres. It covers approximately 20 percent of the Earths surface and about 29 percent of its surface area. It separates the Old World from the New World, the Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Eurasia and Africa to the east, and the Americas to the west. The Equatorial Counter Current subdivides it into the North Atlantic Ocean, in contrast, the term Atlantic originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast. The Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of years ago. The term Aethiopian Ocean, derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century, many Irish or British people refer to the United States and Canada as across the pond, and vice versa. The Black Atlantic refers to the role of ocean in shaping black peoples history. Irish migration to the US is meant when the term The Green Atlantic is used, the term Red Atlantic has been used in reference to the Marxian concept of an Atlantic working class, as well as to the Atlantic experience of indigenous Americans. Correspondingly, the extent and number of oceans and seas varies, the Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea, to the east, the boundaries of the ocean proper are Europe, the Strait of Gibraltar and Africa. In the southeast, the Atlantic merges into the Indian Ocean, the 20° East meridian, running south from Cape Agulhas to Antarctica defines its border. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean, the Atlantic has irregular coasts indented by numerous bays, gulfs, and seas. Including these marginal seas the coast line of the Atlantic measures 111,866 km compared to 135,663 km for the Pacific. Including its marginal seas, the Atlantic covers an area of 106,460,000 km2 or 23. 5% of the ocean and has a volume of 310,410,900 km3 or 23. 3%. Excluding its marginal seas, the Atlantic covers 81,760,000 km2 and has a volume of 305,811,900 km3, the North Atlantic covers 41,490,000 km2 and the South Atlantic 40,270,000 km2. The average depth is 3,646 m and the maximum depth, the bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge. It runs from 87°N or 300 km south of the North Pole to the subantarctic Bouvet Island at 42°S, the MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2000 m along most of its length, the MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other

This is a list of Victory ships. Victory ships were a type of ship which were mass-produced in the United States during World War II. In the following list, Keel refers to the date of the keel laying, Launch to the launch date, the MC Hull No. is a unique number assigned by the United States Maritime Commission. Gaps in the numbers correspond to ships whose contracts were cancelled

United States Maritime Commission
–
It also formed the United States Maritime Service for the training of seagoing ships officers to man the new fleet. The purpose of the Maritime Commission was multifold as described in the Merchant Marine Acts Declaration of Policy. S, Merchant Marine prior to the Act. Another function given to the Commission involved the formation of the U. S. Maritime Service for the training of seagoing ships officers to man the new fleet, the actual licensing of officers and seamen still resided with the Bureau of Marine Inspection and Navigation. President Roosevelt nominated Joseph P. Kennedy first head of the Commission, Kennedy held that position until February 1938 when he left to become US Ambassador to Great Britain. The other four members of the Commission in the years before the beginning of World War II were a mix of retired officers and men from disciplines of law. The man most notable in the group Land brought to the Commission was Commander Howard L. Vickery, USN, as a symbol of the rebirth of the U. S. Upon the U. S. entry into World War II, America was requisitioned by the U. S. Navy and became USS West Point. Most of the C2s and C3s were converted to Navy auxiliaries, notably attack cargo ships, attack transports, the Commission also was tasked with the construction of many hundred military type vessels such as Landing Ship, Tank s and Tacoma-class frigates and large troop transports. By the end of the war, U. S. shipyards working under Maritime Commission contracts had built a total of 5,777 oceangoing merchant, in early 1942 both the training and licensing was transferred to the U. S. S. With the end of World War II, both the Emergency and Long Range shipbuilding programs were terminated as there were far too many merchant vessels now for the Nations peacetime needs. In 1946, the Merchant Ship Sales Act was passed to sell off a portion of the ships previously built during the war to commercial buyers. Although not sold outright to nations that were enemies during the war, for the next 25 years, in ports all around the world one could find dozens of ships which had been built during the war but which now were used in peace. Ships not disposed of through the Ship Sales Act were placed one of eight National Defense Reserve Fleet sites maintained on the Atlantic, Pacific. On several occasions in the postwar years ships in the fleets were activated for both military and humanitarian aid missions. The last major mobilization of the NDRF came during the Vietnam War, since then, a smaller fleet of ships called the Ready Reserve Force has been mobilized to support both humanitarian and military missions. The Maritime Commission was abolished on 24 May 1950, and its functions were divided between the U. S. S. Merchant Marine Academy which had built and opened during World War II. 1936, Merchant Marine Act abolishes Shipping Board and establishes Maritime Commission,1937, Joseph P. S. merchant shipping has been held by many agencies since 1917

Baltimore
–
Baltimore is the largest city in the U. S. state of Maryland, and the 29th-most populous city in the country. It was established by the Constitution of Maryland and is not part of any county, thus, it is the largest independent city in the United States, with a population of 621,849 as of 2015. As of 2010, the population of the Baltimore Metropolitan Area was 2.7 million, founded in 1729, Baltimore is the second largest seaport in the Mid-Atlantic. Baltimores Inner Harbor was once the leading port of entry for immigrants to the United States. With hundreds of identified districts, Baltimore has been dubbed a city of neighborhoods, in the War of 1812, Francis Scott Key wrote The Star-Spangled Banner, later the American national anthem, in Baltimore. More than 65,000 properties, or roughly one in three buildings in the city, are listed on the National Register, more than any city in the nation. The city has 289 properties listed on the National Register of Historic Places, the historical records of the government of Baltimore are located at the Baltimore City Archives. The city is named after Cecil Calvert, second Lord Baltimore, of the Irish House of Lords, Baltimore Manor was the name of the estate in County Longford on which the Calvert family lived in Ireland. Baltimore is an anglicization of the Irish name Baile an Tí Mhóir, in 1608, Captain John Smith traveled 210 miles from Jamestown to the uppermost Chesapeake Bay, leading the first European expedition to the Patapsco River. The name Patapsco is derived from pota-psk-ut, which translates to backwater or tide covered with froth in Algonquian dialect, a quarter century after John Smiths voyage, English colonists began to settle in Maryland. The area constituting the modern City of Baltimore and its area was first settled by David Jones in 1661. He claimed the area today as Harbor East on the east bank of the Jones Falls stream. In the early 1600s, the immediate Baltimore vicinity was populated, if at all. The Baltimore area had been inhabited by Native Americans since at least the 10th millennium BC, one Paleo-Indian site and several Archaic period and Woodland period archaeological sites have been identified in Baltimore, including four from the Late Woodland period. During the Late Woodland period, the culture that is called the Potomac Creek complex resided in the area from Baltimore to the Rappahannock River in Virginia. It was located on the Bush River on land that in 1773 became part of Harford County, in 1674, the General Assembly passed An Act for erecting a Court-house and Prison in each County within this Province. The site of the house and jail for Baltimore County was evidently Old Baltimore near the Bush River. In 1683, the General Assembly passed An Act for Advancement of Trade to establish towns, ports, one of the towns established by the act in Baltimore County was on Bush River, on Town Land, near the Court-House

Maryland
–
The states largest city is Baltimore, and its capital is Annapolis. Among its occasional nicknames are Old Line State, the Free State, the state is named after Henrietta Maria of France, the wife of Charles I of England. George Calvert was the first Lord of Baltimore and the first English proprietor of the colonial grant. Maryland was the state to ratify the United States Constitution. Maryland is one of the smallest U. S. states in terms of area, as well as one of the most densely populated, Maryland has an area of 12,406.68 square miles and is comparable in overall area with Belgium. It is the 42nd largest and 9th smallest state and is closest in size to the state of Hawaii, the next largest state, its neighbor West Virginia, is almost twice the size of Maryland. Maryland possesses a variety of topography within its borders, contributing to its nickname America in Miniature. The mid-portion of this border is interrupted by Washington, D. C. which sits on land that was part of Montgomery and Prince Georges counties and including the town of Georgetown. This land was ceded to the United States Federal Government in 1790 to form the District of Columbia, the Chesapeake Bay nearly bisects the state and the counties east of the bay are known collectively as the Eastern Shore. Close to the town of Hancock, in western Maryland, about two-thirds of the way across the state. This geographical curiosity makes Maryland the narrowest state, bordered by the Mason–Dixon line to the north, portions of Maryland are included in various official and unofficial geographic regions. Much of the Baltimore–Washington corridor lies just south of the Piedmont in the Coastal Plain, earthquakes in Maryland are infrequent and small due to the states distance from seismic/earthquake zones. The M5.8 Virginia earthquake in 2011 was felt moderately throughout Maryland, buildings in the state are not well-designed for earthquakes and can suffer damage easily. The lack of any glacial history accounts for the scarcity of Marylands natural lakes, laurel Oxbow Lake is an over one-hundred-year-old 55-acre natural lake two miles north of Maryland City and adjacent to Russett. Chews Lake is a natural lake two miles south-southeast of Upper Marlboro. There are numerous lakes, the largest of them being the Deep Creek Lake. Maryland has shale formations containing natural gas, where fracking is theoretically possible, as is typical of states on the East Coast, Marylands plant life is abundant and healthy. Middle Atlantic coastal forests, typical of the southeastern Atlantic coastal plain, grow around Chesapeake Bay, moving west, a mixture of Northeastern coastal forests and Southeastern mixed forests cover the central part of the state

Liberty Ship
–
The Liberty ship was a class of cargo ship built in the United States during World War II. Though British in conception, the design was adapted by the United States for its simple, mass-produced on an unprecedented scale, the now iconic Liberty ship came to symbolize U. S. wartime industrial output. The class was developed to meet British orders for transports to replace those torpedoed by German U-boats, the vessels were purchased both for the U. S. fleet and lend-lease deliveries of war materiel to Britain and the Soviet Union. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945, easily the largest number of ships produced to a single design and their production mirrored on a much larger scale the manufacture of the Hog Islander and similar standardized ship types during World War I. Only three Liberty Ships are preserved, two as operational museum ships. S, the number was doubled in 1939 and again in 1940 to 200 ships a year. Ship types included two tankers and three types of merchant vessel, all to be powered by steam turbines, limited industrial capacity, especially for reduction gears, meant that relatively few of these ships were built. In 1940 the British government ordered 60 Ocean-class freighters from American yards to replace war losses and these were simple but fairly large with a single 2,500 horsepower compound steam engine of obsolete but reliable design. Britain specified coal-fired plants, because it then had extensive coal mines, the order specified an 18-inch increase in draft to boost displacement by 800 long tons to 10,100 long tons. The accommodation, bridge, and main engine were located amidships, the first Ocean-class ship, SS Ocean Vanguard, was launched on 16 August 1941. The design was modified by the United States Maritime Commission, in part to increase conformity to American construction practices, but more importantly to make it even quicker and cheaper to build. The US version was designated EC2-S-C1, EC for Emergency Cargo,2 for a ship between 400 and 450 feet long, S for steam engines, and C1 for design C1. The new design replaced much riveting, which accounted for one-third of the costs, with welding. It was adopted as a Merchant Marine Act design, and production awarded to a conglomerate of West Coast engineering and construction companies headed by Henry J. Kaiser known as the Six Companies. Liberty ships were designed to carry 10,000 long tons of cargo, usually one type per ship, but, during wartime, generally carried loads far exceeding this. On 27 March 1941, the number of ships was increased to 200 by the Defense Aid Supplemental Appropriations Act and increased again in April to 306. By 1941, the turbine was the preferred marine steam engine because of its greater efficiency compared to earlier reciprocating compound steam engines. Eighteen different companies built the engine. It had the advantage of ruggedness and simplicity

US 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

Superstructure
–
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of structures such as buildings, bridges. The word superstructure is a combination of the Latin prefix, super with the Latin stem word, in order to improve the response during earthquakes of buildings and bridges, the superstructure might be separated from its foundation by various civil engineering mechanisms or machinery. All together, these implement the system of protection called base isolation. As stated above, superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines and this does not usually include its masts or any armament turrets. Note that in times, turrets do not always carry naval artillery. The size of a watercrafts superstructure can have implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements. These can be detrimental to any vessels performance if they are taken into consideration incorrectly, the height and the weight of superstructure on board a ship or a boat also affects the amount of freeboard that such a vessel requires along its sides, down to her waterline. In broad terms, the more and heavier superstructure that a ship possesses, on a bridge, the portion of the structure that is the span and directly receives the live load is referred to as the superstructure. In contrast, the abutment, piers, and other structures are called the substructure

Forecastle
–
Forecastle refers to the upper deck of a sailing ship forward of the foremast, or the forward part of a ship with the sailors living quarters. Related to the meaning is the phrase before the mast which denotes anything related to ordinary sailors. The syncope of the word, focsle or focsle, is common among nautical terms, the positioning of the apostrophes represents silent letters, thus focsle. In medieval shipbuilding, a ship of war was usually equipped with a tall and it served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, having such tall upper works on the ship was detrimental to sailing performance. Sailors stationed on the forecastle, or forecastle men, were responsible for handling the headsails, in the Royal Navy of the 17th and 18th centuries, these roles were reserved for older seamen who lacked the agility to go aloft or take other more strenuous duties aboard. By the end of the 19th century, raised forecastle had become a feature on warships again, in an attempt to keep forward gun positions from getting unacceptably wet on heavy seas. In addition the forecastle may provide additional crews quarters as in the past, a disadvantage of such a design is the structural weakness at the forecastle break relative to a flush deck structure.

Gasoline tanker
–
A tanker is a merchant vessel designed to transport liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, in the United States Navy and Military Sealift Command, any type of tanker used to refuel other ships is called an oiler. Tankers can range in size of capacity from several hundred tons, besides ocean- or seagoing tankers there are also specialized inland-waterway tankers which operate on rivers and canals with an average cargo capacity up to some thousand tons. Before this, technology had not supported the idea of carrying bulk liquids. The market was not geared towards transporting or selling cargo in bulk, therefore most ships carried a wide range of different products in different holds. Liquids were usually loaded in casks—hence the term tonnage, which refers to the volume of the holds in terms of how many tuns or casks of wine could be carried, even potable water, vital for the survival of the crew, was stowed in casks. Carrying bulk liquids in earlier ships posed several problems, The holds, on ships the holds were not sufficiently water. The development of iron and steel hulls solved this problem, loading and discharging, Bulk liquids must be pumped - the development of efficient pumps and piping systems was vital to the development of the tanker. Steam engines were developed as prime-movers for early pumping systems, dedicated cargo handling facilities were now required ashore too - as was a market for receiving a product in that quantity. Casks could be unloaded using ordinary cranes, and the nature of the casks meant that the volume of liquid was always relatively small - therefore keeping the market more stable. The effect was negligible in casks, but could cause capsizing if the tank extended the width of the ship, tankers were first used by the oil industry to transfer refined fuel in bulk from refineries to customers. This would then be stored in tanks ashore, and subdivided for delivery to individual locations. The use of tankers caught on other liquids were also cheaper to transport in bulk, store in dedicated terminals. Even the Guinness brewery used tankers to transport the stout across the Irish Sea, among oil tankers, supertankers are designed for transporting oil around the Horn of Africa from the Middle East. The supertanker Seawise Giant, scrapped in 2010, was 458 meters in length and 69 meters wide, supertankers are one of the three preferred methods for transporting large quantities of oil, along with pipeline transport and rail. Despite being highly regulated, tankers have been involved in environmental disasters resulting from oil spills, see Amoco Cadiz, Braer, Erika, Exxon Valdez, Prestige oil spill and Torrey Canyon for examples of coastal accidents. Many modern tankers are designed for a cargo and a specific route. Draft is typically limited by the depth of water in loading and unloading harbors, cargoes with high vapor pressure at ambient temperatures may require pressurized tanks or vapor recovery systems

Convoy
–
A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and it may also be used in a non-military sense, for example when driving through remote areas. Arriving at the scene of an emergency with a well-ordered unit. Naval convoys have been in use for centuries, with examples of merchant ships traveling under naval protection dating to the 12th century, the use of organized naval convoys dates from when ships began to be separated into specialist classes and national navies were established. By the French Revolutionary Wars of the late 18th century, effective naval tactics had been developed to ward off pirates. Some convoys contained several hundred merchant ships, the most enduring system of convoys were the Spanish treasure fleets, that sailed from the 1520s until 1790. When merchant ships sailed independently, a privateer could cruise a shipping lane, ships sailing in convoy presented a much smaller target, a convoy was as hard to find as a single ship. As a result of the convoy systems effectiveness, wartime insurance premiums were consistently lower for ships that sailed in convoys, losses of ships travelling out of convoy however were so high that no merchant ship was allowed to sail unescorted. In the early 20th century, the changed the balance of power in convoy battles. Steaming faster than merchant ships and firing at long ranges, a battleship could destroy many ships in a convoy before the others could scatter over the horizon. To protect a convoy against a ship required providing it with an escort of another capital ship. Battleships were the reason that the British Admiralty did not adopt convoy tactics at the start of the first Battle of the Atlantic in World War I. But the German capital ships had been bottled up in the North Sea, the Admiralty took a long time to respond to this change in the tactical position, and in April 1917 convoy was trialled, before being officially introduced in the Atlantic in September 1917. Other arguments against convoy were raised, further, large convoys were thought to overload port resources. Actual analysis of shipping losses in World War I disproved all these arguments, at least so far as they applied to transatlantic, ships sailing in convoys were far less likely to be sunk, even when not provided with any escort at all. The loss of productivity due to delays was small compared with the loss of productivity due to ships being sunk. Ports could deal more easily with convoys because they tended to arrive on schedule, Convoy duty also exposes the escorting warships to the sometimes hazardous conditions of the North Atlantic, with only rare occurrences of visible achievement. The British adopted a system, initially voluntary and later compulsory for almost all merchant ships

New York City
–
The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over an area of about 302.6 square miles. Located at the tip of the state of New York. Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has described as the cultural and financial capital of the world. Situated on one of the worlds largest natural harbors, New York City consists of five boroughs, the five boroughs – Brooklyn, Queens, Manhattan, The Bronx, and Staten Island – were consolidated into a single city in 1898. In 2013, the MSA produced a gross metropolitan product of nearly US$1.39 trillion, in 2012, the CSA generated a GMP of over US$1.55 trillion. NYCs MSA and CSA GDP are higher than all but 11 and 12 countries, New York City traces its origin to its 1624 founding in Lower Manhattan as a trading post by colonists of the Dutch Republic and was named New Amsterdam in 1626. The city and its surroundings came under English control in 1664 and were renamed New York after King Charles II of England granted the lands to his brother, New York served as the capital of the United States from 1785 until 1790. It has been the countrys largest city since 1790, the Statue of Liberty greeted millions of immigrants as they came to the Americas by ship in the late 19th and early 20th centuries and is a symbol of the United States and its democracy. In the 21st century, New York has emerged as a node of creativity and entrepreneurship, social tolerance. Several sources have ranked New York the most photographed city in the world, the names of many of the citys bridges, tapered skyscrapers, and parks are known around the world. Manhattans real estate market is among the most expensive in the world, Manhattans Chinatown incorporates the highest concentration of Chinese people in the Western Hemisphere, with multiple signature Chinatowns developing across the city. Providing continuous 24/7 service, the New York City Subway is one of the most extensive metro systems worldwide, with 472 stations in operation. Over 120 colleges and universities are located in New York City, including Columbia University, New York University, and Rockefeller University, during the Wisconsinan glaciation, the New York City region was situated at the edge of a large ice sheet over 1,000 feet in depth. The ice sheet scraped away large amounts of soil, leaving the bedrock that serves as the foundation for much of New York City today. Later on, movement of the ice sheet would contribute to the separation of what are now Long Island and Staten Island. The first documented visit by a European was in 1524 by Giovanni da Verrazzano, a Florentine explorer in the service of the French crown and he claimed the area for France and named it Nouvelle Angoulême. Heavy ice kept him from further exploration, and he returned to Spain in August and he proceeded to sail up what the Dutch would name the North River, named first by Hudson as the Mauritius after Maurice, Prince of Orange

Destroyer escort
–
Destroyer escort was the United States Navy mid-20th century classification for a 20-knot warship designed with endurance to escort mid-ocean convoys of merchant marine ships. Kaibōkan were designed for a role in the Imperial Japanese Navy. The Royal Navy and Commonwealth forces identified such warships as frigates, Destroyer escorts, frigates and kaibōkan were mass-produced for World War II as a less expensive anti-submarine warfare alternative to fleet destroyers. Post-war destroyer escorts and frigates were larger than those produced during wartime, with increased anti-aircraft capability, as Cold War destroyer escorts became as large as wartime destroyers, the United States Navy converted some of their World War II destroyers to escort destroyers. Full-size destroyers must be able to steam as fast or faster than the fast capital ships such as carriers and cruisers. This typically requires a speed of 25–35 knots and they must carry torpedoes and a smaller caliber of cannon to use against enemy ships, as well as anti-submarine detection equipment and weapons. A destroyer escort needed only to be able to maneuver relative to a slow convoy and these lower requirements greatly reduce the size, cost, and crew required for the destroyer escort. Destroyer escorts were optimized for anti-submarine warfare, having a turning radius. Their much slower speed was not a liability in this context, Destroyer escorts were also considerably more sea-kindly than corvettes. Electric drive was selected because it does not need gearboxes to adjust engine speed to the much lower optimum speed for the propellers, Destroyer escorts were also useful for coastal anti-submarine and radar picket ship duty. During World War II, seven destroyer escorts were converted to radar picket destroyer escorts, although these were relegated to secondary roles after the war, in the mid-1950s twelve more DEs were converted to DERs, serving as such until 1960-1965. Their mission was to extend the Distant Early Warning line on coasts, in conjunction with sixteen Guardian-class radar picket ships, which were converted Liberty ships. In World War II, some 95 destroyer escorts were converted by the US to high-speed transports and this involved adding an extra deck which allowed space for about 10 officers and 150 men. Two large davits were installed, one on either side of the ship. This enabled the UK to commission the US to design, build and supply an escort vessel that was suitable for anti-submarine warfare in deep open ocean situations, cochrane of the American Bureau of Shipping came up with a design which was known as the British Destroyer Escort. S. Navy and one to the Royal Navy, after World War II United States Navy destroyer escorts were referred to as ocean escorts, but retained the hull classification symbol DE. However other navies, most notably those of NATO countries and the USSR, in order to remedy this problem the 1975 ship reclassification reclassified ocean escorts as frigates. This brought the USNs nomenclature more in line with NATO, as of 2006 there are no plans for future frigates for the US Navy

Steam engine
–
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Steam engines are combustion engines, where the working fluid is separated from the combustion products. Non-combustion heat sources such as power, nuclear power or geothermal energy may be used. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle, in the cycle, water is heated and transforms into steam within a boiler operating at a high pressure. When expanded through pistons or turbines, mechanical work is done, the reduced-pressure steam is then exhausted to the atmosphere, or condensed and pumped back into the boiler. Specialized devices such as hammers and steam pile drivers are dependent on the steam pressure supplied from a separate boiler. The use of boiling water to mechanical motion goes back over 2000 years. The Spanish inventor Jerónimo de Ayanz y Beaumont obtained the first patent for an engine in 1606. In 1698 Thomas Savery patented a steam pump that used steam in direct contact with the water being pumped, Saverys steam pump used condensing steam to create a vacuum and draw water into a chamber, and then applied pressurized steam to further pump the water. Thomas Newcomens atmospheric engine was the first commercial steam engine using a piston. In 1781 James Watt patented an engine that produced continuous rotary motion. Watts ten-horsepower engines enabled a range of manufacturing machinery to be powered. The engines could be sited anywhere that water and coal or wood fuel could be obtained, by 1883, engines that could provide 10,000 hp had become feasible. The stationary steam engine was a key component of the Industrial Revolution, the aeolipile described by Hero of Alexandria in the 1st century AD is considered to be the first recorded steam engine. Torque was produced by steam jets exiting the turbine, in the Spanish Empire, the great inventor Jerónimo de Ayanz y Beaumont obtained a patent for the first steam engine in history in 1603. Thomas Savery, in 1698, patented the first practical, atmospheric pressure and it had no piston or moving parts, only taps. It was an engine, a kind of thermic syphon, in which steam was admitted to an empty container. The vacuum thus created was used to water from the sump at the bottom of the mine

Engine room
–
On a ship, the engine room or ER is the propulsion machinery spaces of the vessel. To increase a vessels safety and chances of surviving damage, the necessary for operations may be segregated into various spaces. The engine room is generally the largest physical compartment of the machinery space and it houses the vessels prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine, or some combination of these. On some ships, the space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms. On a large percentage of vessels, ships and boats, the room is located near the bottom, and at the rear, or aft, end of the vessel. This design maximizes the cargo carrying capacity of the vessel and situates the prime mover close to the propeller, minimizing equipment cost, the engine room on some ships may be situated mid-ship, especially on vessels built from 1900 to the 1960s. With the increased use of electric propulsion packages, the engine room may be located well forward, low or high on the vessel. The engine room of a vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ships propeller and they typically burn diesel oil or heavy fuel oil, and may be able to switch between the two. There are many arrangements for motor vessels, some including multiple engines, propellers. Smaller, but still large engines drive electrical generators that power for the ships electrical systems. Large ships typically have three or more synchronized generators to ensure smooth operation, the combined output of a ships generators is well above the actual power requirement to accommodate maintenance or the loss of one generator. On a steamship, power for electricity and propulsion is provided by one or more large boilers giving rise to the alternate name boiler room. High pressure steam from the boiler is used to drive reciprocating engines or turbines for propulsion, besides propulsion and auxiliary engines, a typical engine room contains many smaller engines, including generators, air compressors, feed pumps, and fuel pumps. Today, these machines are powered by small diesel engines or electric motors. The engine get required cooling from liquid-to-liquid heat exchangers connected to fresh seawater or divertible to recirculate through tanks of seawater in the engine room, both supplies draw heat from the engines via the coolant and oil lines. Heat exchangers are plumbed in so that oil is represented by a mark on the flange of the pipes. Sea water, or brine, is represented by a mark on the flanges

The captain goes down with the ship
–
Although often connected to the sinking of the RMS Titanic in 1912 and its captain, Edward J. Smith, the phrase precedes Titanic by at least 11 years. In most instances the captain of the ship forgoes his own rapid departure of a ship in distress and it often results in either the death or belated rescue of the captain as the last person on board. The concept is related to another protocol from the nineteenth century. Both reflect the Victorian ideal of chivalry in which the classes were expected to emulate a morality tied to sacred honour, service. The actions of the captain and men during the sinking of HMS Birkenhead in 1852 prompted praise from many due to the sacrifice of the men who saved the women and children by evacuating them first. Rudyard Kiplings poem Soldier an Sailor Too and Samuel Smiles Self-Help both highlighted the valour of the men who stood at attention and played in the band as their ship was sinking. In a social context, especially as a mariner, the captain will feel compelled to take responsibility as a type of social norm. Shirking this responsibility in a crisis would go against societal mores because of the lack of ethics. In maritime law the responsibility of the master for his ship is paramount no matter what its condition, so abandoning a ship has legal consequences. So even if a captain abandons his ship in distress, he is responsible for it in his absence. Abandoning a ship in distress may be considered a crime that can lead to imprisonment, Captain Francesco Schettino, who left his ship in the midst of the Costa Concordia disaster, was not only widely reviled for his actions, but was arrested by Italian authorities on criminal charges. Abandoning ship is a crime that has been on the books for centuries in Spain, Greece. South Korean law may require the captain to rescue himself last. It is not illegal under maritime law. September 27,1854, James F. Luce was in command of the Collins Line steamer SS Arctic when it collided with SS Vesta off the coast of Newfoundland, Captain Luce regained the surface after initially going down with the ship. He was rescued two days later drifting on wreckage of the same paddle-wheel box that killed his youngest son Willie, september 12,1857, William Lewis Herndon was in command of the commercial mail steamer Central America when it encountered a hurricane. Two ships came to the rescue, but could only save a fraction of the passengers, so Captain Herndon chose to remain with the rest. April 15,1912, Captain Edward Smith, in command of the RMS Titanic when it struck an iceberg, was walking onto the bridge only a few minutes before it was engulfed by the sea

USS Kiowa (AT-72)
–
The third USS Kiowa, later ATF-72, was a fleet tug, later fleet ocean tug, that served in the United States Navy from 1943 to 1972. Kiowa was laid down by the Charleston Shipbuilding & Drydock Company at Charleston, South Carolina, on 22 June 1942 and launched there on 5 November 1942 and she was commissioned on 7 June 1943 as the fleet tug USS Kiowa with Lieutenant William O. Kuykendall in command. After shakedown off Key West, Florida, Kiowa proceeded to Norfolk and she departed Norfolk on 26 July 1943 for operations off Newfoundland. Departing New York three weeks later, Kiowa arrived at Falmouth, England, in the United Kingdom on 19 April 1944 as the Allies were in the planning stages for the invasion of Normandy. On 15 May 1944, she was reclassified as an ocean tug. She remained off Normandy until 25 July 1944 and then operated in British waters before returning to Norfolk on 30 September 1944. For the rest of World War II, Kiowa operated along the United States East Coast, towing and assisting disabled ships, during the late spring of 1945, she commenced operations as a tanker, fueling a number of ships at sea. Kiowa received one star for her World War II service. Following World War II, Kiowa arrived at Naval Station Argentia in the Dominion of Newfoundland on 21 December 1945 for duty in the North Atlantic Ocean. From 1946 to 1959 she conducted operations along the coast of North America from the Panama Canal Zone to Newfoundland, engaged in salvage work and the towing of targets and ships. Arriving at Guantanamo Bay, Cuba, on 9 April 1959 and she cleared San Juan, Puerto Rico, on 26 May 1959 and took station off Antigua as recovery ship for what was to be the beginning of space flight. From 1959 until early 1965, Kiowa continued towing operations out of Norfolk, on 7 September 1965, Kiowa departed Little Creek for the Mediterranean Sea to join the United States Sixth Fleet. Arriving off Naval Station Rota, Spain, on 20 September 1965, she began target-towing, diving support, and salvaging duties which continued into 1966. After this search, Kiowa proceeded to South Wales in the United Kingdom and then to San Juan, Puerto Rico, Kiowa spent the next five months towing targets in the Virginia Capes area before entering drydock at Norfolk on 27 September 1966. Her overhaul completed in late January 1967, Kiowa returned to operations off the United States East Coast, completing a cruise from Bermuda to Canada and back in late 1967. In 1972, Kiowa was loaned to the Dominican Republic under the terms of the Security Assistance Act, renamed Macorix, she operated in the Dominican Navy until decommissioned in 1986. After the Dominican Navy decommissioned her, Macorix was returned to the custody of the United States, the Defense Reutilization and Marketing Service sold her for scrapping on 12 December 1994 This article incorporates text from the public domain Dictionary of American Naval Fighting Ships.

USS Escape (ARS-6)
–
USS Escape was an Diver-class rescue and salvage ship commissioned by the U. S. Navy for service in World War II. She was responsible for coming to the aid of stricken vessels, Escape was launched 22 November 1942 by Basalt Rock Company in Napa, California, sponsored by Mrs. J. E. Brenner, and commissioned 20 November 1943, Lieutenant W. T. Williams in command. Escape sailed from San Diego, California,31 December 1943 for Norfolk, Virginia, between 10 July and 9 September, she performed similar duties out of Bermuda, and on 12 September, put to sea from Norfolk to rescue hurricane-disabled SS George Ade. She reached the ship on the 15th, and brought her safely to port through another violent storm. From 31 December 1944 to 4 June 1945, Escape again operated out of Bermuda and these she laid at Jacksonville, Florida, in October. Escape sailed from Key West, Florida,8 November 1945 to escort and she returned to Norfolk 22 January 1946, and on 20 July 1946 was decommissioned and placed in reserve at Orange, Texas. On 26 January 1960 Escape got underway for Operation Sky Hook, while on station she was diverted to Culebra Island, Puerto Rico, to assist Jonas Ingram which had gone aground. On 30 January 1960 Escape got underway to assist in Project Mercury and she continued to give essential support to the fleet through the remainder of 1960. On 1 September 1978, she was decommissioned and laid up in the National Defense Reserve Fleet, Escape was transferred to U. S. Coast Guard and commissioned USCGC Escape,1 September 1978. She served the Coast Guard until 29 June 1995 when she was returned to the Navy, Escape was decommissioned and returned to Naval custody,29 June 1995. She was struck from the Naval Register,29 June 1995 and she was then laid up in the National Defense Reserve Fleet, James River Group, Fort Eustis, Virginia.

James River
–
The James River is a river in the U. S. state of Virginia. It is 348 miles long, extending to 444 miles if one includes the Jackson River, the James River drains a catchment comprising 10,432 square miles. The watershed includes about 4% open water and an area with a population of 2.5 million people and it is the 12th longest river in the United States that remains entirely within a single state. Tidal waters extend west to Richmond, the capital of Virginia, larger tributaries draining to the tidal portion include the Appomattox River, Chickahominy River, Warwick River, Pagan River, and the Nansemond River. At its mouth near Newport News Point, the Elizabeth River, many boats pass through this river to import and export Virginia products. The navigable portion of the river was the highway of the Colony of Virginia during its first 15 years, facilitating supply ships delivering supplies. However, for the first five years, despite many hopes of gold and riches, in 1612, businessman John Rolfe successfully cultivated a non-native strain of tobacco which proved popular in England. Soon, the became the primary means of exporting the large hogsheads of this cash crop from an ever-growing number of plantations with wharfs along its banks. This development made the efforts of the Virginia Company of London successful financially, spurring even more development, investments. The upper reaches of the river above the head of navigation at the line were explored by fur trading parties sent by Abraham Wood during the late 17th century. Although ocean-going ships were unable to navigate beyond present-day Richmond, portage of products, produce from the Piedmont and Great Valley regions traveled down the river to seaports at Richmond and Manchester through such port towns as Lynchburg, Scottsville, Columbia and Buchanan. The James River was considered as a route for transport of produce from the Ohio Valley, the James River and Kanawha Canal was built for this purpose, to provide a navigable portion of the Kanawha River, a tributary of the Ohio River. For the most mountainous section between the two points, the James River and Kanawha Turnpike was built to provide a link via wagons. However, before the canal could be completed, in the mid-19th century, railroads emerged as a more practical technology. The Chesapeake and Ohio Railway was completed between Richmond and the Ohio River at the new city of Huntington, West Virginia by 1873, dooming the canals economic prospects. In the 1880s, the Richmond and Alleghany Railroad was laid along the portion of the canals towpath. In modern times, this line is used primarily in transporting West Virginia coal to export coal piers at Newport News. The James River contains numerous parks and other recreational attractions, canoeing, fishing, kayaking, hiking, and swimming are some of the activities that people enjoy along the river during the summer

National Defense Reserve Fleet
–
The NDRF is managed by the U. S. Department of Transportations Maritime Administration. It is a different entity from the United States Navy reserve fleets, NDRF vessels are at the fleet sites at James River, Virginia–the James River Reserve Fleet, Beaumont, Texas–the Beaumont Reserve Fleet, and Suisun Bay, California, and at designated outported berths. Former anchorage sites included Stony Point, New York - the Hudson River Reserve Fleet, Wilmington, North Carolina, Mobile, Alabama, Astoria, Oregon, and Olympia, Washington. Through the 2010s, the oldest, most decrepit hulls at Suisun Bay will be stripped of materials, then broken up in Texas. Twenty of the most polluting mothball ships are slated for recycling by 2012, at its peak in 1950, the NDRF had 2,277 ships in lay-up. In July 2007, it held 230 ships, primarily dry cargo ships with some tankers, military auxiliaries, by the end of August,2015, it held 100. The NDRF was established under Section 11 of the Merchant Ship Sales Act of 1946 to serve as a reserve of ships for national defense, NDRF vessels were used in seven wars and crises. During the Korean War,540 vessels were out to move military forces. During a worldwide tonnage shortfall in 1951–53, more than 600 ships were reactivated to carry coal to Northern Europe, from 1955 through 1964, another 600 ships were used to store grain for the Department of Agriculture. Another 223 cargo ships and 29 tankers were activated during a tonnage shortfall after the Suez Canal was closed in 1956, during the Berlin crisis of 1961,18 vessels were activated and remained in service until 1970. Another 172 vessels were activated for the Vietnam War and these are crewed with a reduced crew but kept available for activation within four, five, ten or twenty days. An additional 28 ships are held under United States Maritime Administration custody for other Government agencies on a cost-reimbursable basis. Vessels with military utility or logistic value are held in status and are in a preservation program that is designed to keep them in the same condition as when they enter the fleet. The internal spaces are dehumidified to slow the corrosion of metal, DC power is distributed through anodes to the exterior underwater portions of the hull, creating an electric field that suppresses corrosion and preserves the surface of the hull. External painting and other work is generally deferred since it does not affect the ability to activate and operate the vessel. MARAD is authorized as the government’s disposal agent through the NDRF program for merchant type vessels equal to or greater than 1,500 gross tons. A state agency can file an application to request title to a vessel as-is where-is from the NDRF for the purpose of creating an artificial reef, of the 132 non-retention vessels in the NDRF, there are 117 that are being prepared for disposal. The NDRF program can give and lend historic artifacts to maritime-heritage organizations, battleships, cruisers, and aircraft carriers which have been stricken or those awaiting final disposition may be transferred to MARAD locations for berthing

Hungnam
–
Hŭngnam was the third largest city in North Korea. It is a city on the eastern coast on the Sea of Japan. The city covers an area of 250 square kilometers and it is only eight miles from the slightly inland city of Hamhung. In 2005 it became a ward of Hamhung, the port at Hŭngnam was the site of the Hŭngnam evacuation, a major evacuation of both United Nations military and North Korean civilians during the Korean War in late December 1950. The evacuation included 14,000 refugees who were transported on one ship and this was made possible by a declaration of national emergency by President Truman issued on 16 December 1950 with Presidential Proclamation No. This operation was the culmination of the Battle of Chosin Reservoir, in late 2005, Hŭngnam was demoted from Hŭngnam-si to Hŭngnam-kuyok within Hamhung-si. The population has been estimated at 200,000 or 450,000, the city is home to the Hungnam Fertilizer Complex, which has allegedly also been used to manufacture chemical weapons. Other industrial facilities include the February 8 Vinylon Factory Complex and it is also home to Hungnam Chemical Engineering College. Hungnam Station is on the Pyongra Line railway

Busan, officially Busan Metropolitan City, romanized as Pusan before 2000, is South Koreas second most-populous city after Seoul, with a population of approximately 3.6 million. The population of the area, including the adjacent cities of Gimhae. The city is located on the southeastern-most tip of the Korean peninsula, located within South Koreas largest industrial area, The Southeast Economic Zone, the city is the cultural, educational and economic center of the region. It is the largest port city in South Korea and the fifth busiest seaport by cargo tonnage. The most densely built up areas of the city are situated in a number of narrow valleys between the Nakdong River and the Suyeong River, with mountains separating most of the districts, administratively, it is designated as a Metropolitan City. The Busan metropolitan area is divided into 15 major administrative districts, Busan was the host city of the 2002 Asian Games and the APEC2005 Korea. It was also one of the host cities for the 2002 FIFA World Cup, on November 14,2005, the city authorities officially announced its bid to host the 2020 Summer Olympics Games. After Pyeongchangs successful bid for the 2018 Winter Olympics, Busan is considering bidding to host the 2028 or 2032 Summer Olympics, Busan has Koreas largest beach and longest river, and is home to the worlds largest department store, the Shinsegae Centum City. Geochilsan-guk existed in the second and 3rd and 4th centuries as a chiefdom of Jinhan and it was absorbed by Silla and renamed Geochilsan-gun. The word Geochilsan means rough mountain, probably referring to Hwangbyeongsan, the mounded burials of Bokcheon-dong were built along the top of a ridge that overlooks a wide area that makes up parts of modern-day Dongnae-gu and Yeonje-gu. Archaeologists excavated more than 250 iron weapons and ingots from Burial No,38, a wooden chamber tomb at Bokcheon-dong. In 757, Geochilsan-gun was again renamed Dongnae, which it is still called, from the beginning of the 15th century, the Korean government designated Busan as a trading port with the Japanese and allowed their settlement. Other Japanese settlements in Ulsan and Jinhae diminished later, but the Busan settlement, called Waegwan at the time, after the war, diplomatic relations with the new shogunate in Japan were established in 1607, and Busan Waegwan was permitted to be reconstructed. The Japanese settlement, though relocated into Choryang later, continued to exist until Korea was exposed to modern diplomacy in 1876, in 1876, Busan became the first international port in Korea. During the Japanese rule, Busan developed into a hub trading port with Japan, Busan was the only city in Korea to adopt the steam tramway before electrification was introduced in 1924. During the Korean War, Busan was one of two cities in South Korea not captured by the North Korean army within the first three months of the War. As a result, the city became a camp site for Koreans during the war. As Busan was one of the few areas in Korea that remained under the control of South Korea throughout the Korean War, UN troops established a defensive perimeter around the city known as the Pusan Perimeter in the summer and autumn of 1950

Northwestern Hawaiian Islands
–
The Northwestern Hawaiian Islands or the Leeward Islands are the small islands and atolls in the Hawaiian island chain located northwest of the islands of Kauai and Niihau. They are part of the U. S. state of Hawaii except Midway Atoll, in the state of Hawaii, they are part of Honolulu County. The United States Census Bureau defines this area as Census Tract 114.98 of Honolulu County and its total land area is 3.1075 square miles. All the islands except Nihoa are north of the Tropic of Cancer and it represents the southwestern part of the islands former volcanic cone. Ancient Hawaiians might have stayed here long-term, 40-acre Necker Island is hook shaped and 270 feet tall at its summit. Barren of vegetation, it was used by Ancient Hawaiians for religious purposes, French Frigate Shoals is an atoll, the largest region of coral reefs in Hawaii, at 200 square miles. The atoll is composed of a dozen or so islands, Tern Island housing an airport. Gardner Pinnacles is made up of two small peaks, the last rocky island in Hawaii. While the island itself is tiny, the reef is expansive. 166-square-mile Maro Reef is an extremely fertile reef system that has described as a coral garden. Laysan is a 913-acre, low, sandy island with a lake in its interior. It has arguably the most diverse ecosystem in the NWHI, Lisianski Island, only 400 acres, is geologically akin to Laysan, without the lake. Though the island is slightly less biodiverse, the reef is very fertile. Pearl and Hermes Atoll is an very similar to French Frigate Shoals. For this reason, it was ignored by guano miners. Midway Atoll is the most commonly known of the NWHI, and is also the largest, circular Kure Atoll contains the 236-acre Green Island, which used to host a LORAN station and a runway, but these have since been demolished. In terms of biodiversity, Kure is one of the less impressive of the NWHI, as the Pacific Plate moved north and later northwest over the hot spot, volcanic eruptions built up islands in a linear chain. The isolated land masses gradually eroded and subsided, evolving from high islands in the south, much like the Main Islands of Hawaii, each of the NWHI are in various stages of erosion

Coral reef
–
Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups, the polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support, most reefs grow best in warm, shallow, clear, sunny and agitated waters. Often called rainforests of the sea, shallow coral reefs form some of the most diverse ecosystems on Earth, paradoxically, coral reefs flourish even though they are surrounded by ocean waters that provide few nutrients. They are most commonly found at depths in tropical waters. Coral reefs deliver ecosystem services to tourism, fisheries and shoreline protection, the annual global economic value of coral reefs is estimated between US$29. 8-375 billion. However, coral reefs are fragile ecosystems, partly because they are sensitive to water temperature. Most of the coral reefs we can see today were formed after the last glacial period when melting ice caused the sea level to rise and this means that most modern coral reefs are less than 10,000 years old. As communities established themselves on the shelves, the reefs grew upwards, Reefs that rose too slowly could become drowned reefs. They are covered by so much water there was insufficient light. Coral reefs are found in the sea away from continental shelves, around oceanic islands. The vast majority of islands are volcanic in origin. The few exceptions have tectonic origins where plate movements have lifted the deep ocean floor on the surface. In 1842 in his first monograph, The Structure and Distribution of Coral Reefs, Charles Darwin set out his theory of the formation of atoll reefs and he theorized uplift and subsidence of the Earths crust under the oceans formed the atolls. Darwin’s theory sets out a sequence of three stages in atoll formation and it starts with a fringing reef forming around an extinct volcanic island as the island and ocean floor subsides. As the subsidence continues, the reef becomes a barrier reef. Darwin predicted that underneath each lagoon would be a bed rock base, where the level of the underlying earth allows, the corals grow around the coast to form what he called fringing reefs, and can eventually grow out from the shore to become a barrier reef

Sorghum
–
Sorghum is a genus of flowering plants in the grass family Poaceae. Seventeen of the species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica. One species is grown for grain, while others are used as fodder plants, either intentionally cultivated or allowed to grow naturally. The plants are cultivated in warm climates worldwide and naturalized in many places, Sorghum is in the subfamily Panicoideae and the tribe Andropogoneae. One species, Sorghum bicolor, native to Africa with many cultivated forms now, is an important crop worldwide, used for food, animal fodder, the production of alcoholic beverages, and biofuels. Most varieties are drought- and heat-tolerant, and are important in arid regions. These varieties form important components of pastures in many tropical regions, S. bicolor is an important food crop in Africa, Central America, and South Asia, and is the fifth-most important cereal crop grown in the world. Some species of sorghum can contain levels of cyanide, hordenine. When stressed by drought or heat, plants can contain toxic levels of cyanide and/or nitrates at later stages in growth. Another Sorghum species, Johnson grass, is classified as a species in the US by the Department of Agriculture. Sorghum is efficient in converting solar energy to chemical energy, biofuel, using sweet sorghum as a high sugar content from its stalk for ethanol production, is being developed with biomass which can be turned into charcoal, syngas, and bio-oil. In a 100 gram amount, raw sorghum provides 329 calories, 72% carbohydrates, 4% fat and 11% protein. Sorghum supplies numerous essential nutrients in rich content, including protein, fiber, the B vitamins, niacin, thiamin and vitamin B6, Sorghum nutrient contents generally are similar to those of raw oats. Among other similarities to oats, sorghum contains no gluten, making it useful for gluten-free diets, Agricultural Innovation in the Early Islamic World, The Diffusion of Crops and Farming Techniques, 700–1100.

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

Suisun Bay
–
Suisun Bay is a shallow tidal estuary in northern California. It lies at the confluence of the Sacramento and San Joaquin Rivers, forming the entrance to the Sacramento–San Joaquin River Delta, Suisun Marsh, the tidal marsh land to the north, is the largest marsh in California. Grizzly Bay forms an extension of Suisun Bay. The bay is directly north of Contra Costa County, the bay was named in 1811, after the Suisunes, a Native American tribe of the area. The word originates with the Patwin, on the west, Suisun Bay is drained by the Carquinez Strait, which connects to San Pablo Bay, a northern extension of San Francisco Bay. In addition to the bridges at the Carquinez Strait, it is spanned in its center by the Benicia-Martinez Bridge. It is the anchorage of the Suisun Bay Reserve Fleet, a collection of U. S. Navy and merchant reserve ships, the Glomar Explorer was anchored here after recovering a sunken Soviet submarine in the mid-1970s. Many ships were removed and sold for scrap in the 1990s, in 2010, plans were announced to remove the mothball fleet in stages, with final removal by 2017. The Central Pacific Railroad built a ferry that operated between Benicia and Port Costa, California from 1879 to 1930. The ferry boats Solano and Contra Costa were removed from service when the nearby Martinez railroad bridge was completed in 1930, from 1913 until 1954 the Sacramento Northern Railway, an electrified interurban line, crossed Suisun Bay with the Ramon, a distillate-powered train ferry. Kinder Morgan pleaded guilty to operating a corroded pipeline and paid three dollars in penalties and restitution.

Kaohsiung
–
Kaohsiung City is a special municipality in Taiwan. It is a city with sufficiency as categorized by Globalization. The Kaohsiung International Airport is the second largest airport in Taiwan, the Port of Kaohsiung is the largest harbor in Taiwan, but not officially part of Kaohsiung City. The southern terminal of the Freeway 1 is in Kaohsiung, for north-south travel on railway, the city is served by the Taiwan Railways Administration stations of TRA Western Line and Pingtung Line. The Taiwan High Speed Rail also provides fast and frequent railway connection to Taipei, the Kaohsiung Mass Rapid Transit, the citys subway system, was launched in early 2008. Kaohsiung was the host city of the World Games 2009, a multi-sport event primarily composed of sports not featured in the Olympic Games, the city is also home to the Republic of China Navy fleet headquarters and academy. Hoklo immigrants to the area during the 16th and 17th centuries called it Takau, the surface meaning of the associated Chinese characters was beat the dog. According to one theory, the name Takau originates from the aboriginal Siraya language, according to another theory, the name evolved via metathesis from the name of the Makatao tribe, who inhabited the area at the time of European and Hoklo settlement. On a linguistic basis, the Makatao are considered to have part of a greater Siraya tribe. During the Dutch colonization of southern Taiwan, the area was known as Tancoia to the world for a period of about three decades. In 1662, the Dutch were expelled by the Kingdom of Tungning government and his son, Zheng Jing, renamed the village Banlian-chiu in 1664. The name of Takau was restored in the late 1670s, when the town expanded dramatically with immigrants from mainland China, in his 1903 general history of Taiwan, US Consul to Formosa James W. Davidson relates that Takow was already a well-known name in English. However, in 1920, the name was changed to Takao, while the new name had quite a different surface meaning, its pronunciation in Japanese sounded more or less the same as the old name spoken in Hokkien. After Taiwan was handed to the Republic of China, the name did not change, the name Takau remains the official name of the city in Austronesian languages of Taiwan such as Rukai, although these are not widely spoken in the city. The name also remains popular locally in the naming of businesses, associations, the written history of Kaohsiung can be traced back to the early 17th century, through archeological studies have found signs of human activity in the region from as long as 7000 years ago. Dutch settlers colonizing Taiwan in 1624 referred to the region as Tankoya, the first Chinese records of the region were written in 1603 by Chen Di, a member of Ming admiral Shen You-rongs expedition to rid the waters around Taiwan and Penghu of pirates. The earliest evidence of activity in the Kaohsiung area dates back to roughly 4700–5200 years ago. The prehistoric Dapenkeng, Niuchouzi, Dahu, and Niaosong civilizations were known to inhabit the region, unlike some other archeological sites in the area, the Longquan Temple ruins are relatively well preserved

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

Liberty ship
–
The Liberty ship was a class of cargo ship built in the United States during World War II. Though British in conception, the design was adapted by the United States for its simple, mass-produced on an unprecedented scale, the now iconic Liberty ship came to symbolize U. S. wartime industrial output. The class was developed to meet British orders for transports to replace those torpedoed by German U-boats, the vessels were purchased both for the U. S. fleet and lend-lease deliveries of war materiel to Britain and the Soviet Union. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945, easily the largest number of ships produced to a single design and their production mirrored on a much larger scale the manufacture of the Hog Islander and similar standardized ship types during World War I. Only three Liberty Ships are preserved, two as operational museum ships. S, the number was doubled in 1939 and again in 1940 to 200 ships a year. Ship types included two tankers and three types of merchant vessel, all to be powered by steam turbines, limited industrial capacity, especially for reduction gears, meant that relatively few of these ships were built. In 1940 the British government ordered 60 Ocean-class freighters from American yards to replace war losses and these were simple but fairly large with a single 2,500 horsepower compound steam engine of obsolete but reliable design. Britain specified coal-fired plants, because it then had extensive coal mines, the order specified an 18-inch increase in draft to boost displacement by 800 long tons to 10,100 long tons. The accommodation, bridge, and main engine were located amidships, the first Ocean-class ship, SS Ocean Vanguard, was launched on 16 August 1941. The design was modified by the United States Maritime Commission, in part to increase conformity to American construction practices, but more importantly to make it even quicker and cheaper to build. The US version was designated EC2-S-C1, EC for Emergency Cargo,2 for a ship between 400 and 450 feet long, S for steam engines, and C1 for design C1. The new design replaced much riveting, which accounted for one-third of the costs, with welding. It was adopted as a Merchant Marine Act design, and production awarded to a conglomerate of West Coast engineering and construction companies headed by Henry J. Kaiser known as the Six Companies. Liberty ships were designed to carry 10,000 long tons of cargo, usually one type per ship, but, during wartime, generally carried loads far exceeding this. On 27 March 1941, the number of ships was increased to 200 by the Defense Aid Supplemental Appropriations Act and increased again in April to 306. By 1941, the turbine was the preferred marine steam engine because of its greater efficiency compared to earlier reciprocating compound steam engines. Eighteen different companies built the engine. It had the advantage of ruggedness and simplicity

Type C1 ship
–
Type C1 was a designation for small cargo ships built for the U. S. Maritime Commission before and during World War II. The first C1 types were the smallest of the three original Maritime Commission designs, meant for shorter routes where high speed and capacity were less important, only a handful were delivered prior to Pearl Harbor. But many C1-A and C1-B ships were already in the works and were delivered during 1942, many were converted to military purposes including troop-transports during the war. The Type C1-M ship was a design, for a significantly smaller and shallower draft vessel. This design evolved as an answer for the needs for military transport. Note any Type C1 ship in the control of the British Ministry of War Transport took an Empire name even if being built as another name e. g. Cape Turner. S, shipping Board which had existed since World War I. S. By the end of the war, U. S. shipyards working under MARCOM contracts had built a total of 5,777 oceangoing merchant, what was later known as the C1-A was among the three original cargo ship designs including the basic C2 and C3. Deliveries of the C1-B began before the models, in mid 1941. The C series of ships differed from the Liberty and Victory ships, the first C series vessels were designed prior to hostilities and were meant to be commercially viable ships to modernize the US Merchant Marine, and reduce the US reliance on foreign shipping. The C series ships were more expensive to produce, but their economic viability lasted well into the late 1960s and early 1970s in military, several ships are still in operation. The Type C1-A and C1-B ships were similar in design, All had a top speed of 14 knots. The primary difference between them was that C1-A ships were shelter deck ships, while C1-B ships were full scantling ships, there were many adaptations of the design for special purposes from hospital ships to petroleum gas carriers. With the exception of ships built for specific shipping lines before the war, forty-six Type C1-A ships were built at Pennsylvania Shipyards, Inc. in Beaumont, Texas, with another 19 being built by Pusey and Jones in Wilmington, Delaware. Most were built with motors, though 19 were built with steam turbine engines. These were shelter deck ships, having a very light upper deck, the first keels were laid in 1939. Two of the Pusey and Jones ships were converted to PT boat tenders before entering service, some of the diesel vessels were powered by 2, 6-cylinder Nordberg 2-stroke engines driving the single shaft via magnetic couplings and a reduction gear-box. They were manufactured by Nordberg Manufacturing Company, the engine speed was 220 rpm and the shaft 110 rpm. The engine room was a pleasure to operate and the workmanship outstanding, the Type C1-B ships were built in six different yards, the majority at Consolidated Steel Corporation in Wilmington, California
