The ''Dupleix''-class cruisers were a group of three armoured cruisers built for the French Navy at the beginning of the 20th century. All three ships served in World War I. ==Design and description== Designed by the naval architect Emile Bertin, the ''Dupleix''-class ships measured long overall with a beam of and had a maximum draft (ship) of . They displaced .〔Silverstone, p. 79〕 They had a crew of 531〔Chesneau & Kolesnik, p. 305〕 or 580 officers and enlisted men.〔 The ships had three vertical triple-expansion steam engines, each driving a single propeller shaft. Steam for the engines was provided by 20 or 24 boilers and they were rated at a total of that gave them a speed of .〔 The ''Dupleix''-class ships carried up to of coal〔 and could steam for at a speed of .〔 The ships of the ''Desaix'' class had a main armament that consisted of eight quick-firing (QF) 45-caliber Canon de 164 mm Modèle 1893-96 guns. They were mounted in four twin gun turrets, one each fore and aft of the superstructure and a pair of wing turrets amidships. For anti-torpedo boat defense, they carried four 45-caliber QF guns on the forecastle deck, ten QF Hotchkiss guns. They were also armed with two above water torpedo tubes.〔〔 The Harvey armor belt of the ''Desaix''-class cruisers extended from below the waterline to above it and to a height of at the bow. It covered the entire length of the ship except for of the stern where it ended in a transverse bulkhead thick. The armor was generally thick, although it reduced to forward, and thinned to at its lower edge.〔 The curved protective deck ranged in thickness from . A watertight internal cofferdam, filled with cellulose, was mostly unprotected by the side armor. The gun turrets were protected by armor and the armor of their bases was thick. The 100-millimeter guns were in unprotected hull embrasures on the upper deck. The sides of the conning tower were thick.〔〔The armor layout is somewhat unclear; in ''Directory of the World's Capital Ships'', Silverstone provides different figures, including thinner protection for the gun turrets and conning tower, at and , respectively. See Silverstone, p. 79, for further details.〕 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「Dupleix-class cruiser」の詳細全文を読む スポンサード リンク
