Like the preceding ''Farragut'' Class, their construction was authorized by Congress on 26 April 1916, but funding was delayed considerably. They were designed based on an 1,850-ton standard displacement limit imposed by the London Naval Treaty; the treaty's tonnage limit allowed 13 ships of this size, and the similar was built later to meet the limit. The first four ''Porter''s were laid down in 1933 by New York Shipbuilding in Camden, New Jersey and the next four in 1934 at Bethlehem Steel Corporation in Quincy, Massachusetts. All were commissioned in 1936 except ''Winslow'', which was commissioned in 1937. They were built in response to the large destroyers that the Imperial Japanese Navy was building at the time, and were initially leaders of destroyer flotillas. They served extensively in World War II, in the Pacific War, the Atlantic, and in the Americas. was the class's only loss, in the Battle of the Santa Cruz Islands on 26 October 1942. ==Design== The larger destroyer leader type had been under active consideration since 1921. Indeed the General Board recommended the construction of five of the type in that year. One factor in favor of leaders was the Navy's total lack of modern light cruisers, only partly alleviated by the ten ships built in the 1920s. Naval historian Norman Friedman believed that the great number of and s hindered the U.S. Congress from purchasing new leaders. The General Board was very interested in equipping such a type with the new higher pressure and higher temperature steam propulsion equipment also proposed for the s; this would extend the ships' range.〔Friedman, p.77〕 The London Naval Treaty and large French destroyers (France did not sign the treaty and built ships well in excess of its limits) seem to have become the tipping points, with the 1930 recommendations beginning the cycle to actually build ships.〔Friedman, p.79〕 The Geneva proposals for destroyers also seem to have influence the design, as the Destroyer Leader proposals limited themselves to 1,850 tons per the proposals; these tonnage limits were eventually included in the London treaty.〔 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「Porter-class destroyer」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
