General Dynamics Electric Boat〔(General Dynamics Electric Boat home page )〕 (GDEB) is a subsidiary of General Dynamics Corporation. It has been the primary builder of submarines for the United States Navy for more than 100 years. The company's main facilities are a shipyard in Groton, Connecticut, a hull-fabrication and outfitting facility in Quonset Point, Rhode Island, and a design and engineering facility in New London, Connecticut. ==History== The company was founded in 1899 by Isaac Rice as the Electric Boat Company to build John Philip Holland's submersible designs, which were developed at Lewis Nixon's Crescent Shipyard in Elizabeth, New Jersey. ''Holland VI'' was the first submarine that this shipyard built, later renamed . On 11 April 1900, it became the first modern submarine to be purchased and commissioned into the United States Navy. The success of ''Holland VI'' created a demand for follow-up models (A-class or ) that began with the prototype submersible ''Fulton'' built at Electric Boat (EB). Some foreign navies were interested in John Holland's latest submarine designs, and so purchased the rights to build them under licensing contracts through the Electric Boat Company, and these included Great Britain's Royal Navy, Japan's Imperial Japanese Navy, Russia's Imperial Russian Navy, and the Netherlands' Royal Netherlands Navy. During the World War I era, the company and its subsidiaries (notably Elco) built 85 submarines (via subcontractors) and 722 submarine chasers for the US Navy, and 580 80-foot motor launches for the British Royal Navy.〔Gardiner, p. 101, 132-133〕 After the war, the US Navy did not order another submarine from the company until in 1931.〔Lenton, H. T. ''American Submarines'' (Doubleday, 1973), p.37; Friedman, Norman. ''U.S. Submarines Through 1945: An Illustrated Design History'' (United States Naval Institute Press, 2005), pp. 285–304.〕 During World War II, the company built 74 submarines, while Elco built nearly 400 PT boats.〔Lenton, pp.5 & 62-102 ''passim''.〕 Electric Boat ranked 77th among United States corporations in the value of World War II military production contracts.〔Peck, Merton J. & Scherer, Frederic M. ''The Weapons Acquisition Process: An Economic Analysis'' (1962) Harvard Business School p.619〕 In 1952, Electric Boat was reorganized as General Dynamics Corporation under John Jay Hopkins. General Dynamics acquired Convair the following year, and the holding company assumed the "General Dynamics" name, with the submarine building operation reverting to the "Electric Boat" name.〔(【引用サイトリンク】 title=General Dynamics Corporation )〕 Electric Boat built the first nuclear submarine , which was launched in January 1954, and the first ballistic missile submarine in 1959. Submarines of the -, -, -, and es were also constructed by Electric Boat. In 2002, Electric Boat conducted preservation work on the ''Nautilus'', preparing her for her berth at the US Navy Submarine Force Library and Museum in Groton, Connecticut, where she now resides as a museum. Electric Boat's first submarine ''Holland'' was scrapped in 1932. Electric Boat overhauls and undertakes repair work on fast attack class boats. Electric Boat built the ''Ohio''-class ballistic missile submarines and ''Seawolf''-class submarines, as well as others. However, most of the work done in the shipyard today is focused on construction of the ''Virginia''-class, notably the new Block III evolution. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「General Dynamics Electric Boat」の詳細全文を読む スポンサード リンク
