} |} ''Chesma'' (Russian: ''Чесма'', sometimes transliterated as ''Tchesma'') was the second ship of the s built for the Imperial Russian Navy in the 1880s. When the ship was completed she proved to be very overweight which meant that much of her waterline armor belt was submerged. Russian companies could not produce the most advanced armour and machinery desired by the Naval General Staff, so they were imported from the United Kingdom and Belgium. ''Chesma'' spent her career as part of the Black Sea Fleet. When the crew of the battleship mutinied in June 1905,〔 the ship's crew was considered unreliable and she did not participate in the pursuit of the ''Potemkin''. ''Chesma'' did, however, escort ''Potemkin'' as towed her back to Sevastopol from Constanța, Romania, where ''Potemkin'' had sought asylum. ''Chesma'' was turned over to the Sevastopol port authorities before being stricken on 14 August 1907. Before she was fully dismantled the Naval Ministry decided to use her hull for full-scale armour trials. She was re-designated as ''Stricken Vessel Nr. 4'' on 22 April 1912 before being used as a gunnery target. Afterwards the ship served as a torpedo target for the destroyers of the Black Sea Fleet. During these attacks ''Chesma'' settled to the bottom of the Bay of Tendra and was eventually scrapped during the mid-1920s. == Design and description == ''Chesma'' was long at the waterline and long overall. She had a beam of and a draft of more than than designed. She displaced at load, over more than her designed displacement of .〔McLaughlin, p. 21〕 ''Chesma'' had two 3-cylinder vertical compound steam engines imported from the Belgian Cockerill company. Fourteen cylindrical boilers, also imported from Cockerill, provided steam to the engines. The engines had a total designed output of , but they produced on trials and gave a top speed of almost . At full load she carried of coal that provided her a range of at a speed of and at .〔McLaughlin, pp. 21, 29–30〕 She differed from her sister ships mainly in her main armament. She had six Model 1886 35-caliber guns mounted in twin barbette mounts, two forward, side by side, and one aft. Each of the forward mounts could traverse 30° across the bow and 35° abaft the beam, or a total of 155°. The rear mount could traverse 202°. They had a range of elevation from −2° to +15°. ''Chesma''s guns were mounted on unbalanced turntables and they caused her to list when the guns were trained to one side. Traversing all the guns as far as they could go to one side produced a list of 7.6° and made it very difficult for the turntable machinery to rotate the guns back to the fore-and-aft position.〔McLaughlin, pp. 26–27〕 This problem had been anticipated and water tanks had been added to counteract the list, but they proved to be virtually useless because they took up to two hours to fill. The problem was partially cured in 1892 when the equipment was rearranged on the turntable to improve their balance, but more thorough solutions to the problem were either deemed too expensive or inadequate. Their rate of fire was reportedly one round every fifteen to seventeen minutes, including training time. Sixty rounds per gun were carried. The main guns were mounted very low, (only ) above the main deck, and caused extensive damage to the deck when fired over the bow or stern.〔 They fired a 'light' shell that weighed or a 'heavy' shell that weighed . The 'light' shell had a muzzle velocity of while the 'heavy' shell could only be propelled at a velocity of . The 'light' shell had a maximum range of when fired at an elevation of 15°.〔(【引用サイトリンク】title=Russian 12"/35 (30.5 cm) Pattern 1886 )〕 The seven Obukhov Model 1877 35-caliber guns were mounted on broadside pivot mounts in hull embrasures, except for one gun mounted in the stern in the hull. The eight five-barreled revolving Hotchkiss guns were mounted in small embrasures in the hull to defend the ship against torpedo boats. Four five-barreled revolving Hotchkiss guns were mounted in the fighting top. She carried seven above-water torpedo tubes, one tube forward on each side, able to bear on forward targets, two other tubes were mounted on each broadside forward and aft of the central citadel; the seventh tube was in the stern.〔McLaughlin, pp. 26–28〕 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「Russian battleship Chesma (1886)」の詳細全文を読む スポンサード リンク
