New York Shipbuilding Corporation
–
At its peak during World War II, NYSB was the largest and most productive shipyard in the world. It was founded in 1899 by Henry G. Morse, a noted in connection with bridge design and construction. The original plan was to build a shipyard on Staten Island, site selection specifically considered the needs of the planned application of bridge building practices of prefabrication and assembly line production of ships in covered ways. Construction of the plant began in July 1899 and was so rapid that the keel of the first ship was laid November 1900. That ship, contract number 1, was M. S. Dollar, later to be modified as an oil tanker and renamed J. M. Guffey. Two of the first contracts were for ships that were among the largest then being built in the United States, #5 for Mongolia. Morse died after securing contracts for 20 ships and he was followed as president by De Coursey May. R. Grace & Company and the Pacific Mail Steamship Company, New York Ships unusual covered ways produced everything from aircraft carriers, battleships, and luxury liners to barges and car floats. During World War I, New York Ship expanded rapidly to fill orders from the U. S. Navy and the Emergency Fleet Corporation. A critical shortage of housing led to the construction of Yorkship Village. Yorkship Village is now the Fairview section of the City of Camden, after World War II, a much-diminished New York Ship subsisted on a trickle of contracts from the United States Maritime Administration and the U. S. Navy. The yard launched its last civilian vessel in 1960, and its last naval vessel, the companys final completed submarine was USS Guardfish, which had been ordered in the early 1960s, but construction was halted from 1963 to 1965 because of the loss of the USS Thresher. Guardfish was commissioned in December 1967, in 1968, lacking new naval orders, NYS went bankrupt. USS Pogy, then under construction, was towed to Ingalls Shipbuilding in Pascagoula, Mississippi, the yards site is now part of the Port of Camden, and handles breakbulk cargo. Ships built by New York Ship include, Oil tankers Gulflight launched 1914, center of a diplomatic incident when torpedoed in World War I

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

Cleveland-class cruiser
–
The Cleveland class was a group of light cruisers built for the U. S. Navy during World War II, and were the most numerous class of light cruisers ever built. The Clevland-class was a development of the preceding Brooklyn-class, the ships were designed with the goal of increased cruising range, anti-aircraft armament, torpedo protection, etc. compared with earlier U. S. cruisers. To achieve this, the fifth 6 inch gun turret was omitted and this also gave room for the enlargement of the bridge spaces to accommodate the new combat information center and the necessary radars. However, the increase of light anti-aircraft artillery made the class top-heavy towards the end of World War II, to compensate for the weight increase, some ships had one catapult removed, also the range finders were removed from turret A. These two were called the Fargo class, of the 27 Cleveland-class cruisers that were commissioned, one was completed as a guided missile cruiser and five were later modified as Galveston and Providence-class guided missile cruisers. Two of each of the guided missile cruiser-classes had enlarged superstructures to serve as flagships, following the naming convention at the time, all the ships completed as cruisers were named for US cities and towns. The Cleveland-class cruisers served mainly in the Pacific Fleet during World War II, especially in the Fast Carrier Task Force, all of these warships, though worked heavily and damaged in some cases, survived the war. The Clevelands suffered from increasing stability problems as anti-aircraft armament and additional radar was added during the war, none were recommissioned for the Korean War, as they required a crew almost as large as the Baltimore-class ships, and those ships were reactivated instead. All non-converted ships were sold off from the fleet for scrapping beginning in 1959. The six that were completed as or converted into guided missile cruisers were reactivated during the 1950s, all, particularly the Talos-armed ships, suffered from greater stability problems than the original design due to the extra radar equipment and top weight. This problem was severe in Galveston, leading to its premature decommissioning in 1970. Oklahoma City and Little Rock had to have an amount of ballast. The last of these ships in service, Oklahoma City, was decommissioned in December 1979

Worcester-class cruiser
–
The Worcester class was a class of light cruisers used by the United States Navy, laid down in 1945 and commissioned in 1948-49. They and their contemporaries, the Des Moines-class heavy cruisers, were the last all-gun cruisers built for the U. S. Navy, ten ships were planned for this class, but only two were completed. The main battery layout was distinctive with twin rather than triple turrets, unlike the previous Cleveland-class, St. Louis-class, both ships were decommissioned in 1958, the last conventional light cruisers to serve in the fleet, and scrapped in the early 1970s.

Light cruiser
–
A light cruiser is a type of small- or medium-sized warship. The term is a shortening of the light armored cruiser, describing a small ship that carried armor in the same way as an armored cruiser. Prior to this smaller cruisers had been of the protected cruiser model, the first small steam-powered cruisers were built for the British Royal Navy with HMS Mercury launched in 1878. Such second and third class protected cruisers evolved, gradually becoming faster, better armed, germany took a lead in small cruiser design in the 1890s, building a class of fast cruisers—the Gazelle class—copied by other nations. Such vessels were powered by coal-fired boilers and reciprocating steam engines, the adoption of oil-fired water-tube boilers and steam turbine engines meant that older small cruisers rapidly became obsolete. Furthermore, new construction could not rely on the protection of coal bunkers, the British Bristol group of Town-class cruisers were a departure from previous designs, with turbine propulsion, mixed coal and oil firing and a 2-inch protective armoured belt as well as deck. Thus, by definition, they were armoured cruisers, despite displacing only 4,800 tons, the first true modern light cruisers were the Arethusa class which had all oil-firing and used lightweight destroyer-type machinery to make 29 knots. 1-inch to 5. 9-inch guns. Cruiser construction in Britain continued uninterrupted until Admiral Jacky Fishers appointment as First Sea Lord in 1904, the group of 21 Town-class cruisers begun in 1910 proved excellent in scouting in all types of weather and could carry enough fuel and ammunition to guard the shipping lanes. The Arethusa class, launched three years later, was also successful, British designers continued enlarging and refining subsequent cruiser designs throughout the war. The Germans built a number of cruisers in the belief that they were good multi-purpose vessels. However, the Germans were very late in adapting 5. 9-inch guns, with the Pillau and Wiesbaden-class cruisers the Germans followed the British example of heavier guns. Earlier German light cruisers were in competition with a series of British scout cruisers which had a speed of 25 knots. The Germans completed the last two of their Bremen-class cruisers in 1906 and 1907 and followed them up with four Königsberg-class and these last two classes, larger and faster than the Bremens, were armed the same and carried less deck armor. Other major powers concentrated on construction and built few cruisers. The United States, Italy, and Austria-Hungary each built only a handful of scout cruisers while Japan and Spain added a few based on British designs. The United States resumed building light cruisers in 1918, largely because the ships it then had in service had become obsolete, the first of these, the ten Omaha-class ships, displaced 7,050 tons and were armed with twelve 6-inch guns. Eight of these guns were mounted in casemates at the bow and stern. Fast and maneuverable, they were well-liked as seaboats despite being very wet in rough weather, the term light cruiser was given a definition by the London Naval Treaty of 1930

Babcock & Wilcox
–
Babcock & Wilcox Enterprises is an American power generation company headquartered in Charlotte, North Carolina. The company was founded in 1867 in Providence, Rhode Island by partners Stephen Wilcox and George Babcock as Babcock, Wilcox & Company to manufacture, built nuclear-powered surface ship, NS Savannah. B&Ws boilers supply more than 300,000 megawatts of installed capacity in over 90 countries around the world, a reactor from B&W was destroyed by a nuclear meltdown in the Three Mile Island accident. During World War II, over half of the US Navy fleet was powered by Babcock & Wilcox boilers, the company has its headquarters in Charlotte, North Carolina. B&W also has joint major joint venture companies in Beijing and the Indian city of Pune, on June 30,2015, Babcock & Wilcox completed a spinoff from BWX Technologies, its former parent which is now headquartered in Lynchburg, Virginia. The two companies began trading separately on July 1, B&W employs approximately 5,700 people, in addition to several thousand joint venture employees. B&W PGG and its subsidiaries have facilities in Ohio, Wisconsin, Arona, Italy, Beijing, China, Esbjerg, Denmark, Babcock & Wilcox MEGTEC LLC B&W SPIG Diamond Power International, Inc. The boilers more safely generated higher pressure steam and was more efficient than existing designs, in 1891, Babcock & Wilcox Ltd is established as a separate United Kingdom company, to be responsible for all sales outside the US and Cuba. In 1902 the New York Citys first subway is powered by B&W boilers, during 1907 and 1909 Theodore Roosevelts Great White Fleet were powered by B&W Boilers. In 1929 B&W installs the worlds first commercial size recovery boiler using the magnesium bisulfite process in Quebec, between 1941 and 1945 B&W designed and delivered 4,100 marine boilers for combat and merchant ships, including 95 percent of the US fleet in Tokyo Bay at Japanese surrender. In 1942, the developed the cyclone furnace. Between 1943 and 1945 B&W provided components, materials and process development for Manhattan Project, between 1949 and 1952 B&W provided the 8 boilers for the SS United States, the fastest ocean liner ever constructed. Between 1953 and 1955 B&W designed and fabricated components for USS Nautilus, in 1961 B&W designed and supplied reactors for world’s first commercial nuclear ship NS Savannah. In 1962 B&W designed and furnished reactor systems for B&Ws first commercial reactor, Indian Point, in 1975 B&W designed and built components for liquid metal fast breeder reactors. In 1975 the long term agreements with the British Babcock & Wilcox Ltd were ended. Subsequently, the British company was renamed Babcock International Group plc, in 1978 B&W designed and built the nuclear reactor that was involved in the Three Mile Island accident. In 1999 B&W was awarded the contract to develop fuel cells, on February 22,2000, B&W filed for Chapter 11 bankruptcy in part as a result of thousands of claims for personal injury due to prolonged exposure to asbestos and asbestos fibers. Claims included asbestosis, lung cancer, pleural and peritoneal mesothelioma, as a condition of emerging from bankruptcy, B&W created a trust fund to compensate victims, but for amounts far less than settlements paid in individual personal injury lawsuits

Boiler
–
A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil, the heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. The pressure vessel of a boiler is usually made of steel, stainless steel, especially of the austenitic types, is not used in wetted parts of boilers due to corrosion and stress corrosion cracking. In live steam models, copper or brass is used because it is more easily fabricated in smaller size boilers. For much of the Victorian age of steam, the material used for boilermaking was the highest grade of wrought iron. In the 20th century, design practice instead moved towards the use of steel, which is stronger and cheaper, with welded construction, which is quicker and requires less labour. It should be noted, however, that wrought iron boilers corrode far slower than their steel counterparts. This makes the longevity of older wrought-iron boilers far superior to those of welded steel boilers, cast iron may be used for the heating vessel of domestic water heaters. Although such heaters are usually termed boilers in some countries, their purpose is usually to produce hot water, not steam, the brittleness of cast iron makes it impractical for high-pressure steam boilers. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, electric steam boilers use resistance- or immersion-type heating elements. Nuclear fission is used as a heat source for generating steam, either directly or, in most cases. Heat recovery steam generators use the heat rejected from other such as gas turbine. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam and these could burn wood or most often, coal. Flued boiler with one or two large flues—an early type or forerunner of fire-tube boiler, fire-tube boiler, Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam. This is the type of boiler used in nearly all steam locomotives, the heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point. Fire-tube boilers usually have a low rate of steam production. Fire-tube boilers mostly burn solid fuels, but are adaptable to those of the liquid or gas variety. Water-tube boiler, In this type, tubes filled with water are arranged inside a furnace in a number of possible configurations and this type generally gives high steam production rates, but less storage capacity than the above

General Electric
–
General Electric, often abbreviated as GE, is an American multinational conglomerate corporation incorporated in New York and headquartered in Boston, Massachusetts. In 2011, GE ranked among the Fortune 500 as the 68th-largest firm in the U. S. by gross revenue, as of 2012, the company was listed the fourth-largest in the world among the Forbes Global 2000, further metrics being taken into account. The Nobel Prize has twice been awarded to employees of General Electric, Irving Langmuir in 1932, on January 13,2016, it was announced that GE will be moving its corporate headquarters from Fairfield, Connecticut to the South Boston Waterfront neighborhood of Boston, Massachusetts. The first group of workers arrived in the summer of 2016, morgan and the Vanderbilt family for Edisons lighting experiments. The new company also acquired Sprague Electric Railway & Motor Company in the same year, both plants continue to operate under the GE banner to this day. The company was incorporated in New York, with the Schenectady plant used as headquarters for years thereafter. Around the same time, General Electrics Canadian counterpart, Canadian General Electric, was formed, in 1896, General Electric was one of the original 12 companies listed on the newly formed Dow Jones Industrial Average. After 120 years, it is the one of the original companies still listed on the Dow index. In 1911, General Electric absorbed the National Electric Lamp Association into its lighting business, GE established its lighting division headquarters at Nela Park in East Cleveland, Ohio. Nela Park is still the headquarters for GEs lighting business, owen D. Young, through GE, founded the Radio Corporation of America in 1919 to further international radio. GE used RCA as its retail arm for radio sales from 1919, in 1927, Ernst Alexanderson of GE made the first demonstration of his television broadcasts at his General Electric Realty Plot home at 1132 Adams Rd, Schenectady, NY. The sound was broadcast on GEs WGY, experimental television station W2XAD evolved into station WRGB which—along with WGY and WGFM —was owned and operated by General Electric until 1983. GEs history of working with turbines in the field gave them the engineering know-how to move into the new field of aircraft turbosuperchargers. Led by Sanford Alexander Moss, GE introduced the first superchargers during World War I, superchargers became indispensable in the years immediately prior to World War II, and GE was the world leader in exhaust-driven supercharging when the war started. This experience, in turn, made GE a natural selection to develop the Whittle W.1 jet engine that was demonstrated in the United States in 1941, GE ranked ninth among United States corporations in the value of wartime production contracts. In 2002, GE acquired the assets of Enron during its bankruptcy proceedings. Some consumers boycotted GE light bulbs, refrigerators and other products in the 1980s and 1990s to protest GEs role in weapons production. With IBM, Burroughs, NCR, Control Data Corporation, Honeywell, RCA and UNIVAC, GE had a line of general purpose and special purpose computers

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

Propeller
–
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the blade, and a fluid is accelerated behind the blade. Their disadvantages are higher mechanical complexity and higher cost, the principle employed in using a screw propeller is used in sculling. It is part of the skill of propelling a Venetian gondola but was used in a less refined way in parts of Europe. For example, propelling a canoe with a paddle using a pitch stroke or side slipping a canoe with a scull involves a similar technique. In China, sculling, called lu, was used by the 3rd century AD. In sculling, a blade is moved through an arc. The innovation introduced with the propeller was the extension of that arc through more than 360° by attaching the blade to a rotating shaft. Propellers can have a blade, but in practice there are nearly always more than one so as to balance the forces involved. The origin of the screw propeller starts with Archimedes, who used a screw to lift water for irrigation and bailing boats and it was probably an application of spiral movement in space to a hollow segmented water-wheel used for irrigation by Egyptians for centuries. Leonardo da Vinci adopted the principle to drive his theoretical helicopter, in 1784, J. P. Paucton proposed a gyrocopter-like aircraft using similar screws for both lift and propulsion. At about the time, James Watt proposed using screws to propel boats. This was not his own invention, though, Toogood and Hays had patented it a century earlier, by 1827, Czech-Austrian inventor Josef Ressel had invented a screw propeller which had multiple blades fastened around a conical base. He had tested his propeller in February 1826 on a ship that was manually driven. He was successful in using his bronze screw propeller on an adapted steamboat and his ship Civetta with 48 gross register tons, reached a speed of about six knots. This was the first ship successfully driven by an Archimedes screw-type propeller, after a new steam engine had an accident his experiments were banned by the Austro-Hungarian police as dangerous. Josef Ressel was at the time a forestry inspector for the Austrian Empire, but before this he received an Austro-Hungarian patent for his propeller. This new method of propulsion was an improvement over the paddlewheel as it was not so affected by either ship motions or changes in draft as the burned coal

6"/47 caliber gun
–
The 6/47 caliber Mark 16 gun was a feature of many U. S. light cruisers during World War II. Two versions of gun were built, Mod 0 and Mod 1. These guns were mounted in triple turrets to engage surface targets. Late in the war limited number of two-gun dual-purpose gun turrets mounting the gun were produced capable of engaging air. Today one of the few 6-inch triple gun turrets left in the world is on the museum ship USS Little Rock, compared with the previous 6/53 caliber gun, the 6/47 Mark 16 fired a 130 pounds AP projectile instead of a 105 pounds AP projectile. Each gun could fire a 130-pound projectile 11.36 miles at an elevation of 22.3 degrees with a time of 44.7 seconds. Maximum range at 44.5 degrees elevation was 14.77 miles with a time of 77.3 seconds. Projectiles varied in weight, an armor-piercing projectile weighed 130 pounds, the full charge powder case for these guns was the Mark 4 housed in a brass canister and weighed 65 lb. The HC projectile could be equipped with time or, by late 1942. Eight to ten rounds per minute could be fired from each of the 6-inch guns, each gun weighed 6.5 short tons and could originally only be evevated up to 40 degrees but were later modified to be elevated up to 60 degrees. The guns could only be loaded at between -5 degrees and 20 degrees elevation, this reduced the rate of fire when engaging distant surface targets or aircraft, gun barrel lives were 750 to 1050 full-charge rounds. The turret rested on a barbette or circular shaft that extended several decks into the ship, projectiles were stored in a projectile-handling room in the lower part of the barbette. Two-hundred projectiles, per gun, could be stored in the projectile-handling room, the guns were supplied with projectiles via hoists. Powder stores were below the room and powder hoists fed the guns. Empty powder canisters were ejected from the turret via a port at the back of the turret. When the guns were firing, it was not unusual to see empty brass canisters piling up on the deck behind the turret, the turret itself had 6.5 inches of armor plate on its face and could train to follow its target at ten degrees a second. 6-inch /47 refers to a diameter of 6 inches and a bore length of 47 calibers. Mark 16 indicates it is the 16th design in the series of 6-inch guns, Mod 0 or Mod 1 indicates minor modifications to the design, with 0 being the original and 1 being the first modification

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

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

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

Belt armor
–
Belt armor is a layer of heavy metal armor plated onto or within the outer hulls of warships, typically on battleships, battlecruisers and cruisers, and aircraft carriers. The belt armor is designed to prevent projectiles from penetrating to the heart of a warship, typically, the main armor belt covers the warship from its main deck down to some distance below the waterline. If, instead of forming the hull, the armor belt is built inside the hull, it is installed at a sloped angle for improved protection. Furthermore, the spaces around the main belt in some designs were filled with storage tanks that could contain fuel oil, seawater. The liquids in these tanks absorb or scatter much of the force of warheads. To deal with the leakage from the tanks and incoming seawater and this multilayer design is featured in the cross-sectional drawings of Tirpitz and King George V. In combat, a warship can be seriously damaged underwater not only by torpedoes, to improve protection against both shells and torpedoes, an air space can be added between the armor belt and the hull to increase the buoyancy of the warship. Some kinds of naval warships have belt armor thinner than actually necessary for protection against projectiles and this is common especially with battlecruisers, battleships, and aircraft carriers to reduce their weight, thus increasing their acceleration and speed. Another possible reason is to meet treaty restrictions on ship displacement, one such method is all-or-nothing armoring, where belt armor is stripped from areas deemed non-vital to the functioning of the ship in battle. Agility gained from such processes are an asset to offensive warships that seek to quickly bring their heavy striking power to the enemy. In carriers, the maneuverability is exploited when deploying and recovering aircraft, since planes take off and land most easily when flying into the wind, the aircraft carrier steams rapidly into the wind in both maneuvers, making take-off and landing safer and easier.

Deck (ship)
–
A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the structure that forms the roof of the hull, strengthening it. Decks for some purposes have specific names, the main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the box girder which is the hull. It resists tension, compression, and racking forces, the decks scantling is usually the same as the topsides, or might be heavier if the deck is expected to carry heavier loads. The deck will be reinforced around deck fittings such as the capstan, cleats, on ships with more than one level, deck refers to the level itself. The actual floor surface is called the sole, the term refers to a structural member tying the ships frames or ribs together over the keel. In modern ships, the decks are usually numbered from the primary deck. So the first deck below the deck will be #2. Some merchant ships may alternatively designate decks below the deck, usually machinery spaces, by numbers. Ships may also call decks by common names, or may invent fanciful and romantic names for a deck or area of that specific ship. Equipment mounted on deck, such as the wheel, binnacle, fife rails. Eastern designs developed earlier, with efficient middle decks and minimalist fore, in vessels having more than one deck there are various naming conventions, numerically, alphabetically, etc. However, there are various common historical names and types of decks,01 level is the term used in naval services to refer to the deck above the main deck. The next higher decks are referred to as the 02 level, the 03 level, afterdeck an open deck area toward the stern-aft. Berth deck, A deck next below the gun deck, where the hammocks of the crew are slung, Boat deck, Especially on ships with sponsons, the deck area where lifeboats or the ships gig are stored. Boiler deck, The passenger deck above the vessels boilers, may also refer to the deck of a bridge. Flight deck, A deck from which aircraft take off or land, flush deck, Any continuous unbroken deck from stem to stern

Bulkhead (partition)
–
A bulkhead is an upright wall within the hull of a ship or within the fuselage of an aeroplane. Other kinds of elements within a ship are decks and deckheads. The word bulki meant cargo in Old Norse, sometime in the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head, so walls installed abeam in a vessels hull were called bulkheads. Now, the term applies to every vertical panel aboard a ship. Bulkhead partitions are considered to have been a feature of Chinese junks, song Dynasty author Zhu Yu wrote in his book of 1119 that the hulls of Chinese ships had a bulkhead build. The 5th-century book Garden of Strange Things by Liu Jingshu mentioned that a ship could allow water to enter the bottom without sinking, texts written by Western writers such as Marco Polo, Niccolò Da Conti, and Benjamin Franklin describe the bulkhead partitions of East Asian shipbuilding. Bulkhead partitions became widespread in Western shipbuilding during the early 19th century, a 19th century book on shipbuilding attributes the introduction of watertight bulkheads to Charles Wye Williams, known for his steamships. Some bulkheads and decks are fire-resistance rated to achieve compartmentalisation, a fire protection measure. On an aircraft, bulkheads divide the cabin into multiple areas, openings in fire-resistance rated bulkheads and decks must be firestopped to restore the fire-resistance ratings that would otherwise be compromised, if the openings were left unsealed. The authority having jurisdiction for such measures varies depending upon the flag of the ship, merchant vessels are typically subject to the regulations and inspections of the Coast Guards of the flag country. Combat ships are subject to the set out by the navy of the country that owns the ship. The term was applied to other vehicles, such as railroad cars, hopper cars, trams, automobiles, aircraft or spacecraft, as well as to containers, intermediate bulk containers. In some of these cases bulkheads are airtight to prevent air leakage or the spread of a fire, the term may also be used for the end walls of bulkhead flatcars. Mechanically, a partition or panel through which pass, or a connector designed to pass through a partition. In architecture the term is used to denote any boxed in beam or other downstand from a ceiling. Head strikes on these elements are commonplace hence in architecture any overhead downstand element comes to be referred to as a bulkhead

Gun turret
–
A gun turret is a location from which weapons can be fired that affords protection, visibility, and some cone of fire. Rotating gun turrets have the protection, the weapon, and its crew rotate, when this meaning of the word turret started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets, with a barbette the protection was fixed, in the 1890s, armoured hoods were added to barbettes, these rotated with the platform. By the early 20th Century, these hoods were known as turrets, modern warships have gun-mountings described as turrets, though the protection on them is limited to protection from the weather. They may be manned or remotely controlled and are most often protected to some degree, the protection provided by the turret may be against battle damage, the weather conditions, general environment in which the weapon or its crew will be operating. A small turret, or sub-turret set on top of a one, is called a cupola. The term cupola is used for a rotating turret that carries a sighting device rather than weaponry. Before the development of large-calibre, long-range guns in the mid-19th century, firepower was provided by a large number of guns, each of which could traverse only in a limited arc. Additionally casemate mounts had to be recessed into the side of a vessel to afford a wide arc of fire, designs for a rotating gun turret date back to the late 18th century. The Lady Nancy proved a success and Coles patenting his rotating turret design after the war. Coless aim was to create a ship with the greatest possible all round arc of fire, the Admiralty accepted the principle of the turret gun as a useful innovation, and incorporated it into other new designs. Coles submitted a design for a ship having ten domed turrets each housing two large guns, the design was rejected as impractical, although the Admiralty remained interested in turret ships and instructed its own designers to create better designs. Coles enlisted the support of Prince Albert, who wrote to the first Lord of the Admiralty, in January 1862, the Admiralty agreed to construct a ship, the HMS Prince Albert which had four turrets and a low freeboard, intended only for coastal defence. While Coles designed the turrets the ship was the responsibility of the chief Constructor Isaac Watts, another ship using Coles turret designs, HMS Royal Sovereign, was completed in August 1864. Its existing broadside guns were replaced with four turrets on a flat deck, early ships like the Royal Sovereign had little sea-keeping qualities being limited to coastal waters. Sir Edward James Reed, went on to design and build HMS Monarch, laid down in 1866 and completed in June 1869, it carried two turrets, although the inclusion of a forecastle and poop prevented the turret guns firing fore and aft. The gun turret was independently invented by the Swedish inventor John Ericsson in America, Ericsson designed the USS Monitor in 1861, its most prominent feature being a large cylindrical gun turret mounted amidships above the low-freeboard upper hull, also called the raft. This extended well past the sides of the lower, more traditionally shaped hull, a small armoured pilot house was fitted on the upper deck towards the bow, however, its position prevented Monitor from firing her guns straight forward

Barbette
–
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that led to the pre-dreadnought. The former gives better angles of fire but less protection than the latter, the disappearing gun was a variation on the barbette gun, it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. They were primarily used in coastal defences, but saw use in a handful of warships. The term is used for certain aircraft gun mounts. By the late 1880s, all three systems were replaced with a hybrid system that combined the benefits of both types. The heavily-armored vertical tube that supported the new gun mount was referred to as a barbette, american authors generally refer to such mounts simply as tail guns or tail gun turrets. The use of barbette mountings originated in ground fortifications, the term originally referred to a raised platform on a rampart for one or more guns, enabling them to be fired over a parapet. This gave rise to the phrase en barbette, which referred to a gun placed to fire over a parapet, rather than through an embrasure, while an en barbette emplacement offered wider arcs of fire, it also exposed the guns crew to greater danger from hostile fire. In addition, since the position would be higher than a casemate position—that is. Fortifications in the 19th century typically employed both casemate and barbette emplacements, the type was usually used for coastal defence guns. Later heavy coastal guns were protected in hybrid installation, with wide casemate with cantilevered overhead cover partially covering a barbette mount. Following the introduction of ironclad warships in the early 1860s, naval designers grappled with the problem of mounting guns in the most efficient way possible. The first generation of ironclads employed the same arrangement as the old ship of the line. This was particularly important to designers, since the tactic of ramming was revived following its successful employment at the decisive Austrian victory at the Battle of Lissa in 1866, ramming required a ship to steam directly at its opponent, which greatly increased the importance of end-on fire. Designers such as Cowper Phipps Coles and John Ericsson designed the first gun turrets in the 1860s, in the 1870s, designers began to experiment with an en barbette type of mounting. The barbette was a fixed armoured enclosure protecting the gun, the barbette could take the form of a circular or elongated ring of armour around the rotating gun mount over which the guns fired

Conning tower
–
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer can conn the vessel, i. e. give directions to the helmsman. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship itself and of ocean conditions, the verb “conn” probably stems from the verb “conduct” rather than from another plausible precedent, the verb “control”. On surface ships, the tower was a feature of all battleships. Located at the front end of the superstructure, the tower was a heavily armored cylinder. At all other times than during battles, the ship would be navigated from the bridge instead, conning towers were used by the French on their floating batteries at the Battle of Kinburn. They were then fitted to the first ironclad the French battleship La Gloire, the first Royal Navy conning tower appeared on HMS Warrior which had 3 inches of armour. The King George V class, in contrast to the Nelson class had comparatively light conning tower protection with 4.5 inch sides,3 inch front and rear, and 2 inch roof and deck. The RNs analysis of World War I combat revealed that command personnel were unlikely to utilize an armoured conning tower, older RN battleships that were reconstructed with new superstructures, had their heavily armoured conning towers removed and replaced with much lighter structures. These new conning towers were placed much higher in the ship. Even in the United States Navy, battleship captains and admirals preferred to use the unarmoured bridge positions during combat. The USN had mixed opinions of the tower, pointing out that its weight, high above the ships center of gravity. Beginning in the late 1930s, as radar surpassed visual sighting as the method of detecting other ships, battleships began reducing or eliminating the conning tower. By the end of World War II, US ships were designed with expanded weather bridges enclosing the armored conning towers. With the demise of battleships after World War II, along with the advent of missiles and nuclear weapons during the Cold War, modern warships no longer feature conning towers. It should not be confused with the control room, which was directly below it in the main pressure hull, or the bridge. As improvements in technology allowed the periscopes to be made longer it became unnecessary to raise the station above the main pressure hull. The USS Triton was the last American submarine to have a conning tower, the additional conning tower pressure hull was eliminated and its functions were added to the command and control center. Thus it is incorrect to refer to the sail of a submarine as a conning tower
21.
Floatplane
–
A floatplane is a type of seaplane, with one or more slender pontoons mounted under the fuselage to provide buoyancy. By contrast, a flying boat uses its fuselage for buoyancy, either type of seaplane may also have landing gear suitable for land, making the vehicle an amphibious aircraft. Since World War II and the advent of helicopters, advanced aircraft carriers and land-based aircraft and this, coupled with the increased availability of civilian airstrips, have greatly reduced the number of flying boats being built. These floatplanes have found their niche as one type of plane, for light duty transportation to lakes. They may operate on a basis, provide scheduled service, or be operated by residents of the area for private. Floatplanes have often been derived from land-based aircraft, with fixed floats mounted under the fuselage instead of retractable undercarriage, attaching floats to a landplane also allows for much larger production volumes to pay for the development and production of the small number of aircraft operated from water. Additionally, on all but the largest seaplanes, floatplane wings usually offer more clearance over obstacles, such as docks, a typical single engine flying boat is unable to bring the hull alongside a dock for loading while most floatplanes are able to do so. Floats inevitably impose extra drag and weight, rendering floatplanes slower and less manoeuvrable during flight, with a rate of climb. Some early twin float designs had additional wingtip stabilizing floats, by comparison, dual floats restrict handling, often to waves as little as one foot in height. However, twin float designs facilitate mooring and boarding, and – in the case of torpedo bombers – leave the free to carry a torpedo. Popular Science, February 1945, pp. 134–135

Stern
–
The stern is the back or aft-most part of a ship or boat, technically defined as the area built up over the sternpost, extending upwards from the counter rail to the taffrail. The stern lies opposite of the bow, the foremost part of a ship, originally, the term only referred to the aft port section of the ship, but eventually came to refer to the entire back of a vessel. The stern end of a ship is indicated with a navigation light at night. Sterns on European and American wooden sailing ships began with two forms, the square or transom stern and the elliptical, fantail, or merchant stern. This frame is designed to support the beams that make up the stern. In 1817 the British naval architect Sir Robert Seppings first introduced the concept of the round or circular stern, the square stern had been an easy target for enemy cannon, and could not support the weight of heavy stern chase guns. The United States began building the first elliptical stern warship in 1820, USS Brandywine became the first sailing ship to sport such a stern. In naval architecture, the term transom has two meanings, in this sense, a transom stern is the product of the use of a series of transoms, and hence the two terms have blended. But until a new form of stern appeared in the 19th century, the stern was a floating house—and required just as many timbers, walls, windows. The stern frame provided the structure of the transom stern, and was composed of the sternpost, wing transom. If the stern had transoms above the transom, they would no longer be affixed to the sternpost. The first of these might be called a counter transom, next up was the window sill transom, above that, the larger the vessel, the more numerous and wider the transoms required to support its stern. Stern timbers – These timbers are mounted vertically in a series, each timber typically rests or steps on the transom and then stretches out. Those not reaching all the way to the taffrail are called short stern timbers, the two outermost of these timbers, located at the corners of the stern, are called the side-counter timbers or outer stern timbers. The flat surface of any transom stern may begin either at or above the waterline of the vessel. The geometric line which stretches from the transom to the archboard is called the counter. The visual unpopularity of Seppings circular stern was soon rectified by Sir William Symonds, in this revised stern, a set of straight post timbers stretches from the keel diagonally aft and upward. It rests on the top of the sternpost and runs on either side of the rudder post to a point well above the vessels waterline, the finished stern has a continuous curved edge around the outside and is raked aft

Aircraft catapult
–
An aircraft catapult is a device used to launch aircraft from ships, most commonly used on aircraft carriers, as a form of assisted take off. Different means have been used to propel the catapult, such as weight and derrick, gunpowder, flywheel, air pressure, hydraulic, and steam power. The U. S. Navy is developing the use of Electromagnetic Aircraft Launch Systems with the construction of the Gerald R. Ford class aircraft carrier, aviation pioneer and Smithsonian Secretary Samuel Langley used a spring-operated catapult to launch his successful flying models and his failed aerodrome of 1903. Likewise the Wright Brothers beginning in 1904 used a weight and derrick styled catapult to assist their early aircraft with a takeoff in a limited distance, on 31 July 1912, Theodore Gordon Ellyson became the first person to be launched from a U. S. Navy catapult system. The Navy had been perfecting a compressed-air catapult system and mounted it on the Santee Dock in Annapolis, the first attempt nearly killed Lt. Ellyson when the plane left the ramp with its nose pointing upward and it caught a crosswind, pushing the plane into the water. Ellyson was able to escape from the wreckage unhurt, on 12 November 1912, Lt. Ellyson made history as the Navys first successful catapult launch, from a stationary coal barge. On 5 November 1915, LCDR Henry C, mustin made the first catapult launch from a ship underway. The US Navy experimented with other sources and models, including catapults that utilized gunpowder. On 14 December 1924, a Martin MO-1 observation plane flown by Lt. L. C, hayden was launched from USS Langley using a catapult powered by gunpowder. Following this launch, this method was used aboard both cruisers and battleships, up to and during World War II, most catapults were hydraulic. They were mostly used for experimental purposes, and their use was discontinued during the latter half of the war. Many naval vessels apart from aircraft carriers carried float planes, seaplanes or amphibians for reconnaissance and they were catapult-launched and landed on the sea alongside for recovery by crane. There were submarine aircraft carriers, and some Japanese submarines used them for offensive operations also, the first launch off a Royal Navy battlecruiser was from HMAS Australia on 8 March 1918. The aircraft carried were the Fairey Seafox or Supermarine Walrus, some like HMS Nelson did not use a catapult, and the aircraft was lowered onto the sea for takeoff. Some had their aircraft and catapult removed during WWII e. g. HMS Duke of York and these were used for convoy escort duties to drive off enemy reconnaissance bombers. CAM ships carried a Hawker Sea Hurricane, dubbed a Hurricat or Catafighter, ground-launched V-1s were typically propelled up an inclined launch ramp by an apparatus known as a Dampferzeuger. Following World War II, the Royal Navy was developing a new system for their fleet of carriers. Mitchell, RNV, recommended a system as an effective

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

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

Baltimore-class cruiser
–
The Baltimore-class cruiser was a large class of heavy cruisers in the United States Navy commissioned during or shortly after World War II. Fourteen Baltimores were completed, more than any class of heavy cruiser. Fast and heavily armed, the Baltimore cruisers were used in World War II to protect the fast aircraft carriers in battle groups from air attack. Additionally, their 8-inch main guns and secondary 5-inch guns were used to bombard land targets in support of amphibious landings. After the war, only six Baltimores and two Oregon City-class ships remained in service, while the rest were moved to the reserve fleet, however, all ships except Boston, Canberra, Chicago and Fall River were reactivated for the Korean War. Except for St Paul, all the ships retaining all-gun configurations had very short lives, and by 1971 were decommissioned. However, four Baltimore-class cruisers were refitted and converted some of the first guided missile cruisers in the world. The last of these was decommissioned in 1980, with the Chicago lasting until 1991 in reserve, no example of the Baltimore class still exists. With the start of the war, the limitations instituted by the Second London Naval Treaty, the Baltimore class was based partly on USS Wichita, a heavy cruiser from 1937, which represented the transition from inter-war to World War II designs. It was also based partly on the Cleveland class, a cruiser that was then being built. The construction of the first four ships of the Baltimore class began on July 1,1940, a second order, which consisted of 16 more ships, was approved on August 7,1942. With the construction of the first eight Baltimore-class ships moving slowly, the new, modified design was itself delayed, so that construction had begun on a further six ships—for a total of 14—using the original design before the revisions were completed. The final three ships ordered were converted to the design, known as the Oregon City class. Between 1943 and 1947,17 ships of the Baltimore and Oregon City classes entered service, construction of the eighteenth ship was suspended, to eventually be completed as a flagship/command ship in 1950. Five more were laid down, but cancelled and scrapped before launch, the largest contractor for the construction of the Baltimore-class ships was Bethlehem Steel, which produced eight ships at the Fore River Shipyard in Quincy, Massachusetts. New York Shipbuilding in Camden, New Jersey, built four, the ships were named after cities in the United States, the only exception being USS Canberra, which was named in honor of HMAS Canberra, which had been named after Canberra, the Australian capital. The classification CA originally stood for armored cruiser but was used for heavy cruisers. By 1947, nine of the Baltimores had been decommissioned and placed in the reserve fleet, however, at the start of the 1950s, six were reactivated, making thirteen available for deployment in the Korean War

Oregon City-class cruiser
–
The Oregon City class was a class of heavy cruisers of the United States Navy. Although it was intended to build ten, only four were completed – one of those as a command ship, the three ships completed as cruisers were in commission from 1946 to 1970. The same type of modification also differentiated the Cleveland and Fargo classes of light cruisers, ten ships were authorized for the class with three being completed and the fourth suspended during construction. The final six ships were cancelled,5 after being laid down, construction on the incomplete fourth ship was resumed in 1948 and the ship served as a command ship Northampton. All three completed cruisers were commissioned in 1946, Oregon City was decommissioned after only 22 months of service, one of the shortest active careers of any World War II-era cruiser. Albany was later converted into a missile ship, becoming the lead ship of the Albany class. A similar conversion was planned for Rochester but was cancelled, Albany class cruiser Notes Citations Bibliography Gardiner, Robert and Stephen Chumbley.

Heavy cruiser
–
The heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203mm calibre and displacing approximately 10,000 tons. The heavy cruiser can be seen as a lineage of ship design from 1915 until 1945, the heavy cruisers immediate precursors were the light cruiser designs of the 1900s and 1910s, rather than the armoured cruisers of before 1905. With their intended targets being other cruisers and smaller vessels, the role of the heavy cruiser differed fundamentally from that of the armored cruiser, also, the heavy cruiser was designed to take advantage of advances in naval technology and design. They often had a number of main guns than did armoured cruisers. This arrangement saved tonnage and enabled the ship to all guns on one broadside. They also benefited from the introduction of control in the 1920s and 1930s. These developments meant that the cruiser was an overall more powerful ship type than the armoured cruiser had been. At the end of the 19th century, cruisers were classified as first and their essential role had not changed since the age of sail—to serve on long-range missions, patrol for enemy warships and raid and defend commerce. Armoured cruisers had proved less versatile than needed to do this adequately, in a race to outsize and outgun one another, they had grown to around 15,000 tons and up to 9. While Japanese armored cruisers had distinguished themselves at the Battle of Tsushima in 1905, tactics and technology were gearing towards naval encounters held over increasingly longer ranges, which demanded an armament of primarily large caliber guns. The demand for speed with which to outflank a potential enemy, thirty percent was the ratio by which frigates had been faster than ships of the line in the days of sail. If a battleship sailed at 20 knots, this would mean that an armored cruiser would have to steam at least 26 or 27 knots, armoured cruisers could not fulfill these criteria without being built much larger and taking on a different form than they had in the past. HMS Invincible and her two sister ships were designed specifically to fulfill these requirements, however, they were much larger, faster and better-armed than armored cruisers, able to outpace them, stay out of range of their weapons and destroy them with relative impunity. All these factors made battlecruisers attractive fighting units, although Britain, Germany and they also meant that the armored cruiser as it had been known was now outmoded. No more were built after 1910 and by the end of World War I, although Lord Fisher, the man behind the building of Invincible, had hoped to replace practically all forms of cruisers with battlecruisers, they proved to be too costly to build in large numbers. At the same time, the third class cruiser started to carry thin steel armour on the outside of its hull, the first such design was the British Atlantic cruiser proposal of 1912, which proposed a long-range cruiser of about 8,000 tons displacement with 190 mm guns. This was a response to a rumour that Germany was building cruisers to attack merchant shipping in the Atlantic with 170mm guns, the German raiders proved to be fictional and the Atlantic cruisers were never built. However, in 1915 the requirement for long-range trade-protection cruisers resurfaced and resulted in the Hawkins class, essentially enlarged light cruisers, the Hawkins-class each carried seven 190 mm guns, and had a displacement just under 10,000 tons

USS Fargo (CL-106)
–
USS Fargo, named after the city of Fargo, North Dakota, was the lead ship of her class of light cruisers of the United States Navy, most of which were canceled due to the end of World War II. The cruiser was launched 25 February 1945 by New York Shipbuilding Corporation, Camden, New Jersey, sponsored by Mrs. F. O. Olsen, and commissioned 9 December 1945, Captain Wyatt Craig in command. Through her remaining two years of service, Fargo completed two tours of duty in the Mediterranean, and twice joined in large scale exercises in the Caribbean. A large model of the USS Fargo was on display at the branch of the Fargo Public Library for many years. The model was moved to the Cass County Historical Society at Bonanzaville before being moved to the Fargo air, hull CL-85 was to be named Fargo, but was converted to Langley, an Independence-class light aircraft carrier, during construction.

USS Huntington (CL-107)
–
USS Huntington, a Fargo-class light cruiser, was the second ship of the United States Navy named after the city of Huntington, West Virginia. She was built during World War II but not completed until after the end of the war, after shakedown training off Guantánamo Bay, Cuba, Huntington sailed from Philadelphia on 23 July 1946 for duty with the 6th Fleet in the Mediterranean. During the cruise she visited many ports, including Naples, Malta, Villefranche, returning from her cruise on 13 September 1947, Huntington departed Philadelphia on 24 October with Naval Reserve personnel for exercises off Bermuda and Newfoundland until 14 November 1947. The ship then entered Philadelphia Naval Shipyard and underwent an overhaul until 12 April 1948. During that period Captain Arleigh Burke, future CNO, assumed command in December 1947 until December 1948. Returning to Norfolk on 27 April from her refresher training cruise in the Caribbean, Huntington sailed to Newport, there the ship was honored by an official visit from President Juan Perón, and continuing to Uruguay received a similar visit from President Luis Berres on 10 November. Huntington called at Rio de Janeiro and Trinidad before returning from this good will cruise on 8 December 1948. The cruiser made one cruise from Philadelphia to the Caribbean, returned to Newport on 22 January. She was finally struck from the Navy List on 1 September 1961 after being in reserve and this article incorporates text from the public domain Dictionary of American Naval Fighting Ships.

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

Camden, New Jersey
–
Camden is a city in Camden County, New Jersey. Camden is located directly across the Delaware River from Philadelphia, Pennsylvania, at the 2010 United States Census, the city had a population of 77,344. Camden is the 12th most populous municipality in New Jersey, the city was incorporated on February 13,1828. On March 13,1844, Camden became a county seat in New Jersey, the city derives its name from Charles Pratt, 1st Earl Camden. Camden is made up of twenty different neighborhoods. By the end of the nineteenth century Camden began to industrialize with the foundation of the Campbell Soup Company by Joseph Campbell, other companies such as the New York Shipbuilding Corporation and the Victor Talking Machine Company opened their operations and helped Camden move into an industrial economy. At the beginning of the twentieth century Camdens population consisted mostly of European immigrants, german, British, and Irish immigrants, as well as African Americans from the south made up the majority of the city in the mid nineteenth century. Around the turn of the twentieth century Italian and Eastern European immigrants had become the majority of the population, the city was consistently prosperous throughout the Great Depression and World War II. After World War II Camden manufacturers began closing their factories and moving out of the city, Camdens cultural history has been greatly affected by both its economic and social position over the years. With the loss of manufacturing jobs came a decline in population numbers. Suburbanization also had an effect on the drop in population, Civil unrest and crime became common in Camden with the decline in population. In 1971, civil unrest reached its peak with riots breaking out in response to the death of Horacio Jimenez, Camdens industrial and post-industrial history gave rise to distinct neighborhoods and cultural groups that have affected the status of the city over the course of the 20th century. Over the years Camden has made attempts to restore its economic stature. In the 1980s Mayor Randy Primas campaigned for the city to two different nuisance industries, a prison and a trash-to-steam incinerator. Despite opposition from Camden residents, the Riverfront State Prison was opened in 1985, with the addition of the trash-to-steam plant Camden has faced numerous air and water pollution issues. Camden is also the home of a treatment facility. In the 1970s, dangerous pollutants were found in the wells from which many Camden citizens received their household water and these pollutants decreased property values in Camden and caused health problems among the citys residents. Pollution is an issue that local nonprofits are trying to solve

Fargo-class cruiser
–
The same type of modification differentiated the Baltimore and Oregon City classes of heavy cruisers. Changes were made to order to reduce the instability of the Cleveland-class light cruisers, the main battery turrets sat about a foot lower and the wing gunhouses were lowered to the main deck. The medium anti-aircraft mounts were also lowered, in all,13 ships of the class were planned but only Fargo and Huntington were ever completed, the rest being cancelled at varying states of completion with the de-escalation of World War II. Fargo, the ship of the class, was launched on 25 February 1945. Huntington was commissioned early in 1946, the two ships were decommissioned in 1949-1950, and never reactivated.

William Cramp & Sons
–
William Cramp & Sons Shipbuilding Company of Philadelphia was founded in 1830 by William Cramp, and was the preeminent U. S. iron shipbuilder of the late 19th century. In 1890 the company built the battleships USS Indiana and USS Massachusetts, armored cruiser USS New York, three of these ships took a part in the battle with the Spanish fleet in 1898 at Santiago de Cuba. In 1940, the Navy spent $22 million to reopen the yard as Cramp Shipbuilding to build cruisers, Cramp used the long slipways to construct two submarines at a time, with the intention of launching them simultaneously. However, the submarine construction program was not especially successful. The first delivery was made two years after laying, and fitting out was then done by Portsmouth Navy Yard. The best construction time for a submarine was 644 days, Cramp closed in 1947 and the site, on the Delaware River in Philadelphias Port Richmond neighborhood, became an industrial park. SS Valencia, an ocean liner built for the Red D Line in 1882. She was wrecked on the coastline of Vancouver Island, on January 22,1906, valencias loss is considered one of the worst shipwrecks in the region known as the Graveyard of the Pacific. USS New York, was launched on 2 December 1891 and became flagship of Admiral William T. Sampsons squadron during the Spanish–American War, USS Indiana, Battleship No.1 of the United States Navy, launched 28 February 1893. SS St. Louis and SS St. Paul —the first major ocean liners built in the United States after the collapse of the Collins Line in the 1850s, varyag contracted by Russian Imperial Admiralty, launched October 31,1899. The cruiser was sunk by the crew in Russo-Japanese War, salvaged by the Japanese, SS Evangeline, a coastal passenger liner built in 1927 for the Eastern Steamship Company. While operating as the cruise ship Yarmouth Castle in 1965, she caught fire, on 6 September 1941, the keel for the Cleveland-class light cruiser designated CL-90 was laid down by the Cramp Shipbuilding Company. On 6 March 1943, CL-90 USS Astoria was launched, on 8 December 1942, the keel to the Cleveland-class light cruiser designated CL-91, was laid down by the Cramp Shipbuilding Company. On 22 April 1943, Oklahomans were outraged, having just learned that the Japanese had executed the captured American pilots from Jimmy Doolittles bombing raid over Tokyo. That same day, booths were set up in Oklahoma City with the a goal to sell $40 million in War Bonds to fund the construction of a cruiser and that goal was topped by $5 million when the booths closed that night. CL-91 then became the USS Oklahoma City, the last ship Cramps built was the cruiser USS Galveston, launched on April 22,1945.

Philadelphia
–
In 1682, William Penn, an English Quaker, founded the city to serve as capital of the Pennsylvania Colony. Philadelphia was one of the capitals in the Revolutionary War. In the 19th century, Philadelphia became an industrial center. It became a destination for African-Americans in the Great Migration. The areas many universities and colleges make Philadelphia a top international study destination, as the city has evolved into an educational, with a gross domestic product of $388 billion, Philadelphia ranks ninth among world cities and fourth in the nation. Philadelphia is the center of activity in Pennsylvania and is home to seven Fortune 1000 companies. The Philadelphia skyline is growing, with a market of almost 81,900 commercial properties in 2016 including several prominent skyscrapers. The city is known for its arts, culture, and rich history, Philadelphia has more outdoor sculptures and murals than any other American city. Fairmount Park, when combined with the adjacent Wissahickon Valley Park in the watershed, is one of the largest contiguous urban park areas in the United States. The 67 National Historic Landmarks in the city helped account for the $10 billion generated by tourism, Philadelphia is the only World Heritage City in the United States. Before Europeans arrived, the Philadelphia area was home to the Lenape Indians in the village of Shackamaxon, the Lenape are a Native American tribe and First Nations band government. They are also called Delaware Indians and their territory was along the Delaware River watershed, western Long Island. Most Lenape were pushed out of their Delaware homeland during the 18th century by expanding European colonies, Lenape communities were weakened by newly introduced diseases, mainly smallpox, and violent conflict with Europeans. Iroquois people occasionally fought the Lenape, surviving Lenape moved west into the upper Ohio River basin. The American Revolutionary War and United States independence pushed them further west, in the 1860s, the United States government sent most Lenape remaining in the eastern United States to the Indian Territory under the Indian removal policy. In the 21st century, most Lenape now reside in the US state of Oklahoma, with communities living also in Wisconsin, Ontario. The Dutch considered the entire Delaware River valley to be part of their New Netherland colony, in 1638, Swedish settlers led by renegade Dutch established the colony of New Sweden at Fort Christina and quickly spread out in the valley. In 1644, New Sweden supported the Susquehannocks in their defeat of the English colony of Maryland

Newport News Shipbuilding
–
Founded as the Chesapeake Dry Dock and Construction Co. in 1886, Newport News Shipbuilding has built more than 800 ships, including both naval and commercial ships. Located in the city of Newport News, their facilities more than 550 acres. The shipyard is building the aircraft carriers USS Gerald R. Ford, also under construction are the Virginia-class submarines USS Indiana and USS Washington. In 2013, Newport News Shipbuilding began the deactivation of the first nuclear-powered aircraft carrier, USS Enterprise, Newport News Shipbuilding also performs refueling and complex overhaul work on Nimitz-class aircraft carriers. This is a four-year vessel renewal program that not only involves refueling of the nuclear reactors. The yard has completed RCOH for four Nimitz-class carriers, as of May 2016 this work was underway for the fifth Nimitz-class vessel, USS Abraham Lincoln. Industrialist Collis P. Huntington provided crucial funding to complete the Chesapeake and Ohio Railroad from Richmond, however, building the railroad and coal pier was only the first part of Huntingtons dreams for Newport News. In 1886 he built a shipyard to repair ships servicing this transportation hub, in 1891 Newport News Shipbuilding and Drydock Company delivered its first ship, the tugboat Dorothy. By 1897 NNS had built three warships for the US Navy, USS Nashville, Wilmington and Helena, when Collis died in 1900, his nephew Henry E. Huntington inherited much of his uncles fortune. He also married Collis widow Arabella Huntington, and assumed Colliss leadership role with Newport News Shipbuilding, under Henry Huntingtons leadership, growth continued. In 1906 the revolutionary HMS Dreadnought launched a naval race worldwide. Between 1907 and 1923, Newport News built six of the US Navys total of 22 dreadnoughts – USS Delaware, Texas, Pennsylvania, Mississippi, Maryland, all but the first were in active service in World War II. In 1907 President Theodore Roosevelt sent the Great White Fleet on its round-the-world voyage, NNS had built seven of its 16 battleships. In 1914 NNS built SS Medina for the Mallory Steamship Company, in the early years, leaders of the Newport News community and those of the shipyard were virtually interchangeable. Post served from March 9,1911 to Feb.12,1912, earlier, he had come to the area as one of the builders of the C&O Railways terminals, and had served as the first mayor of Newport News after it became an independent city in 1896. It was on March 14,1914 that Albert Lloyd Hopkins and his assistant, Frederic Gauntlett, was also on board, but was able to swim to safety. Homer Lenoir Ferguson was company vice president when Hopkins died, and he saw the company through both world wars, became a noted community leader, and was a co-founder of the Mariners Museum with Archer Huntington. He served until July 31,1946, after the second World War had ended on both the European and Pacific fronts

Newport News, Virginia
–
Newport News is an independent city located in the Commonwealth of Virginia. As of the 2010 census, the population was 180,719, in 2013, the population was estimated to be 183,412, making it the fifth-most populous city in Virginia. Newport News is included in the Hampton Roads metropolitan area, the area now known as Newport News was once a part of Warwick County. Warwick County was one of the eight original shires of Virginia, formed by the House of Burgesses in the British Colony of Virginia by order of King Charles I, the county was largely composed of farms and undeveloped land until almost 250 years later. In 1881,15 years of development began under the leadership of Collis P. With the new railroad came a terminal and coal piers where the colliers were loaded, within a few years, Huntington and his associates also built a large shipyard. In 1896, the new incorporated town of Newport News, which had briefly replaced Denbigh as the county seat of Warwick County, had a population of 9,000. In 1958, by mutual consent by referendum, Newport News was consolidated with the former Warwick County, the more widely known name of Newport News was selected as they formed what was then Virginias third largest independent city in population. The location on the harbor and along the James River facilitates a large boating industry which can take advantage of its miles of waterfront. Newport News also serves as a junction between the rails and the sea with the Newport News Marine Terminals located at the East End of the city. Served by major east-west Interstate Highway 64, it is linked to others of the cities of Hampton Roads by the circumferential Hampton Roads Beltway, part of the Newport News/Williamsburg International Airport is in the city limits. The original area near the mouth of the James River was first referred to as Newportes Newes as early as 1621, the source of the name Newport News is not known with certainty. Several versions are recorded, and it is the subject of popular speculation locally, the new governor ordered them to turn around, and return to Jamestown. Under this theory, the community was named for Newports good news, another possibility is that the community may have derived its name from an old English word news meaning new town. At least one source claims that the New arose from the settlements being rebuilt after a fire. Another source gave the name as New Port Newce, named for a person with the name Newce. The namesake, Sir William Newce, was an English soldier, there he had established Newcestown near Bandon, County Cork. He sailed to Virginia with Sir Francis Wyatt in October 1621 and was granted 2,500 acres of land and his brother, Capt. Thomas Newce, was given 600 acres at Kequatan, now called Elizabeth Cittie

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Annapolis, Maryland
–
Annapolis is the capital of the U. S. state of Maryland, as well as the county seat of Anne Arundel County. Its population was measured at 38,394 by the 2010 census, the city served as the seat of the Continental Congress in 1783–84 and was the site of the 1786 Annapolis Convention and the Annapolis Peace Conference, held in 2007. Annapolis is the home of St. Johns College as well as the United States Naval Academy, a settlement in the Province of Maryland named Providence was founded on the north shore of the Severn River in 1649 by Puritan exiles from Virginia led by Governor William Stone. The settlers later moved to a harbor on the south shore. The settlement on the shore was initially named Town at Proctors, then Town at the Severn. In 1654, after the Third English Civil War, Parliamentary forces assumed control of Maryland, per orders from Charles Calvert, fifth Lord Baltimore, Stone returned the following spring at the head of a Cavalier force. On March 25,1655, in what is known as the Battle of the Severn, Stone was defeated, taken prisoner, Fendall governed Maryland during the latter half of the Commonwealth. In 1660, he was replaced by Phillip Calvert as fifth/sixth Governor of Maryland), Annapolis was incorporated as a city in 1708. Water trades such as oyster-packing, boatbuilding and sailmaking became the chief industries. Annapolis is home to a number of recreational boats that have largely replaced the seafood industry in the city. Dr. Alexander Hamilton was a Scottish-born doctor and writer who lived and worked in Annapolis, Annapolis became the temporary capital of the United States after the signing of the Treaty of Paris in 1783. For the 1783 Congress, the Governor of Maryland commissioned John Shaw, the flag is slightly different from other designs of the time. The blue field extends over the height of the hoist. Shaw created two versions of the flag, one started with a red stripe and another that started with a white one. In 1786, delegates from all states of the Union were invited to meet in Annapolis to consider measures for the regulation of commerce. Delegates from only five states—New York, Pennsylvania, Virginia, New Jersey, the Philadelphia convention drafted and approved the Constitution of the United States, which is still in force. During this period, a prisoner of war camp, Camp Parole, was set up in Annapolis. As the war continued, the camp expanded to a location just west of the city

United States Naval Institute
–
In addition to publishing magazines and books, the Naval Institute holds several annual conferences. Established in 1873, the Naval Institute currently has about 50,000 members, mostly active and retired personnel of the United States Navy, Marine Corps, the organization also has members in over 90 countries. Its chair is former NATO Supreme Allied Commander Europe James G. Stavridis and its CEO is Peter H. Daly, a retired Navy vice admiral. The U. S. Naval Institute was established as a forum for the exchange of ideas, to disseminate and advance the knowledge of sea power, rear Admiral John L. Worden served as the first president. In 1874, the Naval Institute began to accept papers and publish the proceedings of its discussions which were distributed to the organization’s members, a practice that continues to this day. Two decades later, the Naval Institute Press was created to publish basic naval guides, it expanded to publish more general-interest titles in history, biography. Having outgrown its offices at Preble Hall, the Naval Institute gave the building to the Naval Academy and, in 1999, the monthly magazine Proceedings is the Naval Institutes flagship product. Published since 1874, it is one of the oldest continuously published magazines in the United States, issues include articles from military professionals and civilian experts, historical essays, book reviews, full-color photography, and reader commentary. Roughly a third are written by active duty and active reserve personnel, a third by retired military, the magazine has published controversial articles on contentious issues, moreover, military brass have been known to block certain articles from being submitted to the journal. For example, in 1962, DoD officials prevented a Marine Corps lieutenant colonel from sending to Proceedings an article about a 1949 proposal to merge the Marines aviation units into the Air Force. Naval History magazine was first published in 1987 to explore the role of sea power in U. S. history, the Naval Institute Press was founded in 1898 and publishes about 80 books a year. Among the professional development titles are The Bluejackets Manual, Naval Shiphandling, The Naval Officers Guide, The Marine Officer’s Guide, the Naval Institute Guide to Combat Fleets of the World and The Naval Institute Guide to Ships and Aircraft of the U. S. Fleet are popular reference books with the military, media and maritime enthusiasts, launched in December 2008, the blog is another forum for debate. Contributors have included former NATO Supreme Commander Admiral James G. Stavridis, USN and Admiral Thad Allen, launched in February 2012, USNI News provides breaking news and insight on emerging issues. In 1985, the Institute began to hold conferences, open to the public, the largest of these, are held in San Diego and Washington, D. C. The conferences often feature the Chief of Naval Operations and the Commandant of the Marine Corps, in 2007, USNI produced Americans At War, a series of video interviews with U. S. combat veterans of conflicts dating to World War I. Former President George H. W. Bush, Senators Bob Dole, Daniel Inouye, Bob Kerrey, the series was broadcast on Public Broadcasting Service television stations nationwide. The U. S.

Juneau-class cruiser
–
The Juneau-class cruisers were United States Navy light cruisers which were modified version of the Atlanta-class cruiser design. Three ships were ordered and built, all completed shortly after World War II, watertight integrity was improved by removing doors on the lowest decks of the ship between bulkheads. In addition, all the armament was removed, along with the torpedo battery. The main gun battery of the Juneau-class was composed of six dual 5 inch/38 caliber gun mounts, the class was designed with a secondary anti-aircraft armament of thirty-two Bofors 40 mm anti-aircraft guns, and sixteen 20 mm rapid-fire anti-aircraft cannons with high-explosive shells. After the war, the ships were planned to convert to a 3 inch/50 caliber secondary armament to replace the 40mm guns, on trial the Juneau made 32.48 knots at 78,985 SHP. The ships of the Juneau-class had the armor as the Atlanta-class, a maximum of 3.5 in on their sides, with the captains bridge. The ships were designed for 47 officers and 695 men. Spokane was launched on 22 September 1945, and commissioned on 17 May 1946, fresno was launched on 5 March 1946 and commissioned on 27 November 1946. She was decommissioned in 1955, shortly after the war ended, all three ships were considered for refitting as guided missile cruisers or ASW ships but ultimately were sold for scrap in the 1960s.

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

Lexington-class aircraft carrier
–
The Lexington-class aircraft carriers were a pair of aircraft carriers built for the United States Navy during the 1920s. The ships were built on hulls originally laid down as battlecruisers after World War I, the Treaty, however, allowed two of the unfinished ships to be converted to carriers. They were the first operational aircraft carriers in the USN and were used to carrier aviation tactics. They proved extremely successful as carriers and experience with the Lexington class convinced the Navy of the value of large carriers and they were the largest aircraft carriers in the USN until the Midway-class aircraft carriers were completed beginning in 1945. The ships served in World War II, seeing action in many battles and she supported Allied operations in the Indian Ocean and South West Pacific Areas until she became a training ship at the end of 1943. Saratoga returned to combat to protect American forces during the Battle of Iwo Jima in early 1945, the continued growth in the size and weight of carrier aircraft made her obsolete by the end of the war. In mid-1946, the ship was sunk during nuclear tests in Operation Crossroads. The Lexington-class was originally designed as battlecruisers, with guns, high speed. The Navy laid down six ships of the class in 1919–20, when the battlecruisers were cancelled under the Washington Naval Treaty of 1922, two of the unfinished ships were designated for completion as carriers. Lexington and Saratoga were selected since they were the most advanced of the six ships in construction, conversion became a series of compromises and mixed blessings which would not have arisen had they been specifically designed carriers from the outset. On the plus side, the ships would have better protection, larger magazines for aircraft bombs and, with the after elevator 28 feet higher than otherwise. A brand-new aircraft carrier was estimated at $27.1 million, conversion of a Lexington class was $22.4 million, not counting the $6.7 million already sunk into them. Added together, the rose to $28.1 million. The bottom line, with the signing of the treaty, was that any capital ships under construction by the five signatories had to be canceled and scrapped, for battlecruisers, this encompassed the United States Lexington class, Japans Amagi class, and Great Britains G3 battlecruisers. For the U. S. Navy, the choice seemed clear, if it scrapped all six Lexingtons in accordance with the treaty, it would throw away $13.4 million that could otherwise go toward aircraft carriers. The Navy opted for the latter course, the next challenge the Navys Bureau of Construction and Repair faced was the tonnage cap set by the treaty. Carriers were to be no more than 27,000 tons, an exception, spearheaded by Assistant Secretary of the Navy Theodore Roosevelt Jr. and added to the treaty, allowed capital ships under conversion to go up to 33,000 tons, an increase of 6000 tons. This would almost not be enough for a conversion without removing half the power plant, creative interpreting of a clause in the treaty allowed a potential way out of this situation

USS Ranger (CV-4)
–
USS Ranger was the first ship of the United States Navy to be designed and built from the keel up as an aircraft carrier. Ranger was a small ship, closer in size and displacement to the first US carrier—Langley—than later ships. An island superstructure was not included in the design, but was added after completion. Deemed too slow for use with the Pacific Fleets carrier task forces against Japan, Ranger saw combat in that theatre and provided air support for Operation Torch. In October 1943, she fought in Operation Leader, air attacks on German shipping off Norway, the ship was sold for scrap in 1947. The Washington Naval Treaty limited both the size of ships that could be built and the total tonnage of aircraft carriers that could be built. What became Ranger was to be the first purpose-built aircraft carrier of the United States Navy, the carrier cost 15.2 million dollars. Ranger had a narrow hull due to its size and one inch of armor on the hangar deck, due to space limits, the carrier was equipped with geared turbines. The design was modified to include an island, increasing the displacement to 14,500 tons. The smoke from the six boilers was vented up six small stacks. The stacks were hinged and were rotated to a parallel with the hangar deck during flight operations. Ranger also incorporated a gallery deck between the deck and hangar deck. The hangar deck was semi-open and had large roll-up metal curtain doors which could be closed in bad weather, one was located on the centerline and two offset to the starboard centerline. It was originally planned to install two catapults on the deck to allow the launching of observation aircraft but this plan was dropped. The carrier was able to carry 76 aircraft at the time, Ranger was armed with six 40 mm quadruple mounts and forty-six 20 mm mounts. She also was armed with eight 5-inch /25 caliber guns, which were removed in June 1944. The carrier was one of the first U. S. Navy ships mounted with light weapons to defend against dive-bombing attacks. The U. S. Navy opened bids for the construction of the carrier on 3 September 1930

Yorktown-class aircraft carrier
–
The Yorktown class was a class of three aircraft carriers built by for the United States Navy and completed shortly before World War II. They immediately followed Ranger, the first U. S. These ships bore the brunt of early action in the Pacific War, Enterprise, the sole survivor of the class, was the most decorated ship of the U. S. Navy in the Second World War. After efforts to save her as a ship failed, she was scrapped in 1960. A forerunner to modern development, the Yorktown class was a result of standardized war gaming exercises using Langley. The Naval War College became the repository of American Naval expertise. The results were that islands on the carriers were highlighted and speed itself was considered very important, the 27,000 ton plan for the Yorktown class was a fall back plan from a 23,000 ton carrier that could not achieve that desired speed. The realization that larger carriers would be more survivable was a happy coincidence, nevertheless, the war games and the Naval War College highlighted the greater flexibility presented by large air groups and fast speed. These became along with protection, the guiding principles in the Yorktown class designs. In particular, the 23,000 ton design had to sacrifice protection features, all studies showed that the 27,000 ton designs were to be preferred however all treaty limitations made this impossible. Later it would be noted that the carriers provided close to an all weather ability to launch aircraft. The British Royal Navy had constructed several carriers during this time, admiral Marc Mitscher had in particular pushed for such a carrier. The American Naval Attache J. C. Hunsacker reported that HMS Furious had problems deposing of the fumes without proper smoke stacks, the aviation community continued to demand flush decked carriers. Given additional problems with controlling air groups all American carriers would be constructed with islands, in any case BuAer retracted all demands for flush decked carriers. The 1931 design show an island and the design for USS Ranger the contractor stated that gun control was impossible without a raised island, both USS Ranger and USS Wasp further showed the limitations of sub-20,000 ton designs. USS Ranger proved to be unable to withstand rougher weather in the Pacific while lack of any protective features soon relegated her to a training ship. USS Wasps lack of torpedo protection contributed to her loss in the Pacific theater, as the result of this experience, the U. S. Navy built Yorktown and Enterprise, commissioned in 1937 and 1938 respectively. These were fast and versatile carriers able to carry and operate over 80 warplanes which was almost as many as the much larger Lexington class

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

Essex-class aircraft carrier
–
The Essex class was a class of aircraft carriers of the United States Navy that constituted the 20th centurys most numerous class of capital ships. The class consisted of 24 vessels, which came in both short-hull and long-hull versions, thirty-two ships were originally ordered, however as World War II wound down, six were canceled before construction, and two were canceled after construction had begun. No Essex-class ships were lost to enemy action, despite several vessels sustaining very heavy damage, at the time of the repudiations, both Italy and Japan had colonial ambitions, intending on or already conducting military conquests. A longer, wider deck and a deck-edge elevator facilitated more efficient aviation operations. Machinery arrangement and armor protection was improved from previous designs. These features, plus the provision of more guns, gave the ships much enhanced survivability. Some ships in the class would serve until well after the end of the Vietnam War, debates raged, and continue to this day, regarding the effect of strength deck location. British designers comments tended to disparage the use of deck armor. After the abrogation of disarmament treaties by Japan in 1936, the U. S. took a look at its naval strength. With the Naval Expansion Act of Congress passed on 17 May 1938 and this permitted the building of Hornet, which was the third Yorktown-class CV, and Essex, which was the lead ship of a new class. CV-9 was to be the prototype of the 27, 000-ton aircraft carrier, considerably larger than Enterprise, the Navy ordered the first three of the new design, CV-9, CV-10 and CV-11, from Newport News Shipbuilding & Drydock on 3 July 1940. These were to become known as Essex-class carriers, under the terms of the Two-Ocean Navy Act, ten more of these carriers were programmed. After the US declaration of war, Congress appropriated funds for nineteen more Essexes, ten were ordered in August 1942 and three more in June 1943. Only two of these were completed in time to see active World War II service, six ships ordered in 1944 were canceled before construction was begun. The first eight hulls were originally assigned names from historic Navy ships, Lexington was originally laid down as Cabot, but was renamed during construction after the original USS Lexington was lost in the Battle of the Coral Sea in May 1942. Yorktown, originally to be named Bon Homme Richard, was renamed after the original USS Yorktown was lost at the Battle of Midway on 7 June 1942, Lexington and Yorktown share the unique distinction of being named after both historic ships and historic battles. The erstwhile Valley Forge was renamed Princeton after USS Princeton was sunk in the Battle of Leyte Gulf in October 1944, at the conclusion of the war, the six ships ordered but never laid down were canceled. Of the nine still unfinished six were completed, two were scrapped, and Oriskany was taken in hand for modification to an improved design, in drawing up the preliminary design for Essex, particular attention was directed at the size of both the flight and hangar decks

Midway-class aircraft carrier
–
The Midway-class aircraft carrier was one of the longest-serving aircraft carrier designs in history. First commissioned in late 1945, the ship of the class, USS Midway, was not decommissioned until 1992. The USS Franklin D. Roosevelt was decommissioned in 1977, the USS Coral Sea was decommissioned in 1990. The CVB-41 class vessels were conceived in 1940 as a design study to determine the effect of including an armored flight deck on a carrier the size of the Essex class. The resulting calculations showed that the effect would be a reduction of air group size—the resulting ship would have an air group of 64, Navy carrier design were incorporated in the CVB Class, then still under development. HMS ILLUSTRIOUS in an action off Malta on 1 January 1941 was hit by several bombs, the concept went to finding a larger carrier that could support both deck armor and a sufficiently large air group. They would be the last USN carriers to be so designed, the resulting carriers were very large, with the ability to accommodate more planes than any other carrier in the U. S. fleet. In their original configuration, the Midway-class ships had an airwing of almost 130 aircraft and it was soon realized that the coordination of so many planes was beyond the effective command and control ability of one ship. However, their size did allow these ships to easily accommodate the rapid growth in aircraft size. While the resulting ships featured excellent protection and unprecedented airwing size, internally, the ships were very cramped and crowded. Freeboard was unusually low for such large carriers, in seas, they shipped large amounts of water. In addition, in contrast with the earlier Lexington, Yorktown and Essex-classes, although they were intended to augment the US Pacific fleet during World War II, the lead ship of the class, Midway, was not commissioned until 10 September 1945. None of the went on war cruises during the Korean War. They were mainly deployed to the Atlantic and Mediterranean, all three of the Midway class made combat deployments in the Vietnam War. Coral Sea deployed to the Gulf of Tonkin six times, Midway deployed on three occasions, and Franklin D. Roosevelt made one combat deployment before returning to the Mediterranean. In the late 1960s, Midway underwent a modernization and reconstruction program. By the 1970s, Franklin D. Roosevelt and Coral Sea were showing their age, all three retained the McDonnell Douglas F-4 Phantom II in their air wings, being too small to operate the new Grumman F-14 Tomcat fleet defense fighter or the S-3 Viking anti-submarine jet. In 1977, Franklin D. Roosevelt was decommissioned, on her final deployment, Roosevelt embarked AV-8 Harrier jump jets to test the concept of including VSTOL aircraft in a carrier air wing

Light aircraft carrier
–
A light aircraft carrier, or light fleet carrier, is an aircraft carrier that is smaller than the standard carriers of a navy. The precise definition of the type varies by country, light carriers typically have a complement of aircraft only one-half to two-thirds the size of a fleet carrier. In World War II, the United States Navy produced a number of light carriers by converting cruiser hulls. The Independence-class ships, however, had the virtue of being available at a time when available carrier decks had been reduced to Enterprise and Saratoga in the Pacific, in addition, unlike escort carriers, they had enough speed to take part in fleet actions with the larger carriers. Late in the war, a follow on design to the Independence-class, two vessels in this class—Saipan and Wright—were completed after the wars end. After very brief lives as carriers, the Saipans were converted to command, the British 1942 design light fleet carrier was a scaled-down version of their Illustrious-class fleet carrier. The design could be built in a yard with little or no experience of warship construction, although built to merchant standards, the design incorporated better watertight subdivision. Expected to have a lifetime of three years, the last of the design was taken out of service in 2001. The first eight were built as the Colossus but revisions upgrading the design to larger and heavier aircraft led to the remainder being the Majestic class. In the post-war period, the Royal Navy operated a force of ten Colossus class carriers including the two maintenance carriers, by 1939 HMS Hermes was being considered as equivalent to a light aircraft carrier, due to her small size and lack of armour. Currently five light carriers are in service. The newest light carriers are the Italian Cavour and the Spanish Juan Carlos I, aircraft Carriers of the World,1914 to the Present. Watts, Anthony J.

Independence-class aircraft carrier
–
The Independence-class aircraft carriers were a class of light carriers built for the United States Navy that served during World War II. Adapted from the design for Cleveland-class light cruisers, this class of ship resulted from the interest of President Franklin D. Roosevelt in naval air power. With war looming, the former Assistant Secretary of the Navy noted no new aircraft carriers were expected to be completed before 1944. He proposed to some of the many cruisers then under construction to carriers. Undeterred, President Roosevelt ordered another study, on 25 October 1941, the Navys Bureau of Ships reported that aircraft carriers converted from cruiser hulls would be of lesser capability, but available much sooner. After the December 1941 attack on Pearl Harbor, the need for more carriers became urgent, the Navy accelerated construction of the 34,000 ton Essex-class aircraft carriers, but these large ships could not be finished quickly. So in January 1942, the Navy also ordered that a Cleveland-class light cruiser then under construction be completed instead as an aircraft carrier. It became the USS Belleau Wood, the first ship of the Independence-class, plans developed for this conversion showed much more promise than expected. Two more light cruisers were reordered as carriers in February, three more in March, and a three in June 1942. The Independence-class design had a short and narrow flight deck and hangar. The hangar, flight deck, and island represented a significant increase in the topside weight. To compensate for this, blisters were added to the original cruiser hull, Ships of this class carried a small air group - only about 30 aircraft. This was originally set to consist of nine fighters, nine bombers, and nine torpedo bombers. These were limited-capability ships, whose principal virtue was near-term availability and their limited size made for seakeeping difficulties in the many typhoons of the Pacific, and their small flight decks led to a relatively high aircraft accident rate. However, being based on a cruiser, they were fast ships. The cruiser hull and engineering allowed them the necessary to operate with the main fleet carrier task groups. Their names followed the US Navys policy of naming aircraft carriers after historic navy ships or historic battles, eight of these carriers participated in the Battle of the Philippine Sea in June 1944, which effectively ended Japans carrier air power. The light carriers provided 40 percent of the Fast Carrier Task Forces fighters and 36 percent of the torpedo bombers
