They were officially classed as large cruisers (CB), but others have regarded them as battlecruisers. They were all named after territories or insular areas of the United States, signifying their intermediate status between larger battleships and smaller heavy and lighter cruisers. Of the six planned, two were completed, the third's construction was suspended on 16 April 1947, and the last three were canceled. and served with the U.S. Navy for the last year of World War II as bombardment ships and fast carrier escorts. They were decommissioned in 1947 after spending only 32 and 29 months in service, respectively. The idea for a large cruiser class originated in the early 1930s when the U.S. Navy sought to counter ''Deutschland''-class "pocket battleships" being launched by Germany. Planning for ships that eventually evolved into the ''Alaska'' class began in the late 1930s after the deployment of Germany's s and rumors that Japan was constructing a new battlecruiser class.〔Worth, 305.〕 To serve as "cruiser-killers" capable of seeking out and destroying these post-Treaty heavy cruisers, the class was given large guns of a new and expensive design, limited armor protection against 12-inch shells, and machinery capable of speeds of about 31–33 knots (36–38 mph, 58–61 km/h). == Background == Heavy cruiser development steadied between World War I and World War II thanks to the terms of the Washington Naval Treaty and successor treaties and conferences, where the United States, Britain, Japan, France, and Italy agreed to limit heavy cruisers to 10,000 tons displacement with 8-inch main armament. Up until the ''Alaska'' class, US cruisers designed between the wars followed this pattern.〔Bauer and Roberts, 139.〕 The initial impetus for the ''Alaska'' design came from the deployments of Germany's so-called pocket battleships in the early 1930s. Though no actions were immediately taken, these thoughts were revived in the late 1930s when intelligence reports indicated Japan was planning or building "super cruisers" that would be much more powerful than the current US heavy cruisers.〔〔〔〔Scarpaci, 17.〕 The navy responded in 1938 when the General Board asked the Bureau of Construction and Repair to conduct a "comprehensive study of all types of naval vessels for consideration for a new and expanded building program".〔Dulin, Jr., Garzke, Jr., 189.〕 The US President at the time, Franklin Delano Roosevelt, may have taken a lead role in the development of the class with his desire to have a counter to raiding abilities of Japanese cruisers and German pocket battleships.〔Dulin, Jr. and Garzke, Jr., 24 and 179.〕 While these claims are difficult to verify,〔〔Morison and Polmar, 85.〕 they have led to the speculation that their design was "politically motivated".〔Dulin Jr., Garzke, Jr., 267.〕 These were the most powerful cruisers ever built. 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「Alaska-class cruiser」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.
