The CC-class submarine was the first class of submarines used by the Royal Canadian Navy. Designed as diesel-electric submarines for use as coastal defence, they saw no battle while in service during the First World War and were paid off in 1920. They were the first Canadian warships to pass through the Panama Canal.〔Macpherson & Barrie, p.15〕 Both ships were discarded in 1925. They were originally purchased by the province of British Columbia from a shipbuilder in Seattle, Washington, which had built the submarines for the Chilean Navy. The CC class are similar to the British C-class submarines, and served as prototypes for the Holland 602 type submarine. ==Design== The two submarines were not identical. The design called for diesel-electric submarines for use as coastal defence. The submarine that would become known as ''CC-1'' displaced 313 tons and had a length , a beam of and a draught of . The submarine that would be known as ''CC-2'' displaced 310 tons, had a length of , a beam of and a draught of .〔Colledge, p.115〕 ''CC-1'' was armed with five torpedo tubes, four forward and one astern. ''CC-2'' was armed with three torpedo tubes of the same size, two forward and one astern.〔Johnston et al. p.312〕 Both ships used Whitehead Mk IV 18-inch torpedoes that had a range of at .〔Ferguson, 2014〕 The only source for these torpedoes in Canada was 's stock and it took some time before they were shipped to the submarines.〔 The boats could dive and unlike modern submarines, the main ballast and trim tanks were located internally. The CC-class could carry of diesel fuel.〔 The two submarines were designed to make surfaced and submerged, however ''CC-1'' made in sea trials in November 1917.〔 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「CC-class submarine」の詳細全文を読む スポンサード リンク
