HMS ''Collingwood'' was a dreadnought battleship built for the Royal Navy in the first decade of the 20th century. She spent her whole career assigned to the Home and Grand Fleets and often served as a flagship. Prince Albert (later King George VI) spent several years aboard the ship before and during World War I. At the Battle of Jutland in May 1916, ''Collingwood'' was in the middle of the battleline and lightly damaged a German battlecruiser. Other than that battle, and the inconclusive Action of 19 August, her service during the war generally consisted of routine patrols and training in the North Sea. The ship was deemed obsolete after the war; she was reduced to reserve and used as a training ship before being sold for scrap in 1922. ==Design and description== The design of the ''St Vincent'' class was derived from that of the previous , with a slight increase in size, armour and more powerful guns, among other more minor changes. ''Collingwood'' had an overall length of , a beam of ,〔Burt, pp. 75–76〕 and a normal draught of .〔Preston, p. 125〕 She displaced at normal load and at deep load. In 1911 her crew numbered 758 officers and enlisted men.〔 ''Collingwood'' was powered by two sets of Parsons direct-drive steam turbines, each driving two shafts, using steam from eighteen Yarrow boilers. The turbines were rated at and intended to reach a maximum speed of . During her full-power, eight-hour sea trials on 17 January 1910, the ship only reached a top speed of from . She had a range of at a cruising speed of .〔Burt, pp. 76, 80〕 The ''St Vincent'' class was equipped with ten breech-loading (BL) 12-inch Mk XI guns in five twin-gun turrets, three along the centreline and the remaining two as wing turrets. The secondary, or anti-torpedo boat, armament comprised twenty BL 4-inch Mk VII guns. Two of these guns were each installed on the roofs of the fore and aft centreline turrets and the wing turrets in unshielded mounts, and the other ten were positioned in the superstructure. All guns were in single mounts.〔Burt, p. 76〕 The ships were also fitted with three 18-inch torpedo tubes, one on each broadside and the third in the stern.〔 The ''St Vincent''-class ships had a waterline belt of Krupp cemented armour (KC) that was thick between the fore and aftmost barbettes, reducing to a thickness of before it reached the ships' ends. Above this was a strake of armour thick. Transverse bulkheads inches thick terminated the thickest parts of the waterline and upper armour belts once they reached the outer portions of the endmost barbettes.〔Burt, pp. 76, 78; Parkes, p. 503〕 The three centreline barbettes were protected by armour thick above the main deck that thinned to below it. The wing barbettes were similar except that they had 10 inches of armour on their outer faces. The gun turrets had faces and sides with roofs. The three armoured decks ranged in thicknesses from . The front and sides of the forward conning tower were protected by 11-inch plates, although the rear and roof were 8 inches and 3 inches thick respectively.〔Burt, pp. 76, 78; Parkes, p. 504〕 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「HMS Collingwood (1908)」の詳細全文を読む スポンサード リンク
