HMS ''Suffolk'' was one of 10 armoured cruisers built for the Royal Navy in the first decade of the 20th century. Upon completion she was assigned to the 3rd Cruiser Squadron of the Mediterranean Fleet and was then assigned to the 3rd Cruiser Squadron in the Mediterranean in 1909 after a lengthy refit. She returned home for another refit in 1912 and became the flagship of the 4th Cruiser Squadron on the North America and West Indies Station in 1913. After the beginning of World War I in August 1914, ''Suffolk'' became a private ship and searched for German commerce raiders while protecting British shipping. She captured a German merchantman shortly after the war began. She remained in the Atlantic until she became flagship of the China Station in 1917 In late 1918 the ship was deployed to Vladivostok to support the Siberian Intervention during the Russian Civil War. She returned home in 1919 and briefly became a training ship before she was sold for scrap in 1920. ==Design and description== ''Suffolk'' was designed to displace . The ship had an overall length of , a beam of and a deep draught of . She was powered by two 4-cylinder triple-expansion steam engines, each driving one shaft, which produced a total of and gave a maximum speed of . ''Suffolk'', however, was one of two ''Monmouth''s that exceeded her designed speed; during her sea trials she reached . The engines were powered by 31 Niclausse boilers.〔Chesneau & Kolesnik, p. 70〕 She carried a maximum of of coal and her complement consisted of 678 officers and enlisted men.〔Friedman 2012, p. 336〕 Her main armament consisted of fourteen breech-loading (BL) 6-inch Mk VII guns.〔Friedman 2011, p. 81〕 Four of these guns were mounted in two twin-gun turrets, one each fore and aft of the superstructure and the others positioned in casemates amidships. Six of these were mounted on the main deck and were only usable in calm weather.〔Friedman 2012, pp. 251–52, 260–61〕 They had a maximum range of approximately with their shells.〔Friedman 2011, pp. 80–81〕 Ten quick-firing (QF) 12-pounder 12 cwt guns were fitted for defence against torpedo boats.〔 ''Suffolk'' also carried three 3-pounder Hotchkiss guns and two submerged 18-inch torpedo tubes.〔 Beginning in 1915, the main deck six-inch guns of the ''Monmouth''-class ships were moved to the upper deck and given gun shields. Their casemates were plated over to improve seakeeping. The twelve-pounder guns displaced by the transfer were repositioned elsewhere. At some point in the war, 2 three-pounder anti-aircraft guns were installed on the upper deck.〔Friedman 2012, pp. 280, 286〕 The ship's waterline armour belt had a maximum thickness of and was closed off by transverse bulkheads. The armour of the gun turrets and their barbettes was four inches thick while the casemate armour was five inches thick. The protective deck armour ranged in thickness from and the conning tower was protected by of armour.〔 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 Suffolk (1903)」の詳細全文を読む スポンサード リンク
