The ''Centurion''-class battleships were second-class pre-dreadnought battleships built for the Royal Navy in the 1890s. They were designed for service on distant stations. ==Description== The ''Centurion'' class comprised two ships, ''Centurion'' and ''Barfleur''. The ships were designed by Sir William White to be lightly armed battleships designed for service on the China Station and Pacific Station. Their relative lack of firepower enabled greater quantities of coal to be carried, extending their range, and it was not thought they would face the big guns of an enemy fleet. They were too lightly armed to slug it out with enemy battleships, but they could outrun them, and they were more than capable of dealing with armored cruisers that they were far more likely to meet on distant stations. They were considered good steamers and good seaboats, although the use of forced draft was discontinued because it damaged their boilers. Their draughts were designed to be shallow enough to allow passage through the Suez Canal and the navigation of rivers in China. Their hulls were sheathed with wood and copper to reduce fouling and hence allow them to sail longer between docking. The ships were armed with four 10 inch (254 mm) guns in two barbettes covered by open-backed armored hoods and capable of all-around loading, a secondary armament of ten 4.7 inch (120 mm) guns, numerous smaller guns, and seven torpedo tubes. The previous ''Royal Sovereign''-class battleships had allowed a comparison between high-freeboard ships with their main guns in open barbettes and low-freeboard ships equipped with old-style, heavy, circular turrets and had proven the superiority of the former in the rough waters of the Atlantic; the ''Centurion''s were the first barbette-type battleships with armored hoods over their barbettes, giving rise to the armored gunhouses that would be mounted on later ships and which themselves would come to be known as "turrets." ''Centurion'' in 1901–1903 and ''Barfleur'' in 1902–1904 underwent a reconstruction in which their 4.7 inch (120 mm) guns were replaced by 6 inch (152 mm) guns in armored casemates, the additional weight being compensated for by reductions in their masts and the removal of all five of their above-water torpedo tubes. They were slightly slower, at about , after these refits. Like all pre-dreadnoughts, the ''Centurion''s were completely outclassed by the new dreadnought battleships that began to appear in 1906, and were scrapped a few years later after a period in reserve. 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「Centurion-class battleship」の詳細全文を読む スポンサード リンク
