The ''Bahia'' class was a pair of scout cruisers built for Brazil by Armstrong Whitworth in the United Kingdom, based on a design that borrowed heavily from the British scout cruisers. The class comprised the lead ship and her sister , along with a canceled third ship, ''Ceara''.〔"The Brazilian Navy," ''Times'' (London), 28 December 1908, 48f.〕 Both were named after states of Brazil. As a class, they were the fastest cruisers in the world when commissioned, and the first in the Brazilian Navy to use steam turbines for propulsion. In the mid-1920s, both ships were extensively modernized with three new Brown–Curtis turbine engines and six new Thornycroft boilers, and, in the process, was converted from coal-burning ships to oil-burning. The refit resulted in a striking aesthetic change, with the exhaust being trunked into three funnels, instead of two. The armament was also modified; three , a Hotchkiss machine gun, and four torpedo tubes were added. In the Second World War, both were used as convoy escorts. On 4 July 1945, ''Bahia'' was lost after an accident caused a massive explosion which incapacitated the ship and sunk her within minutes, resulting a large loss of life. ''Rio Grande do Sul'' survived the war and was scrapped in 1948. ==Design== The class's design borrowed heavily from the British scout cruisers.〔 The ships displaced ,〔〔 and their dimensions were overall, between perpendiculars, at the beam, and a draft of forward, amidships, and aft.〔 They were powered by five Parsons steam turbines, and ten Yarrow boilers, with a coal bunker that could hold a normal load of , and a maximum load of .〔 The ''Bahia'' class was designed to reach a speed of ;〔 both ships exceeded this during trials with ''Bahia'' reaching at trial.〔 As designed, the class's range was at , or at .〔 The class was armed with ten /50 caliber, six 〔〔 and two torpedo tubes.〔 The class was lightly armored with only of deck armor, with the conning tower having .〔 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「Bahia-class cruiser」の詳細全文を読む スポンサード リンク
