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
