The Russian ironclad ''Sevastopol'' ((ロシア語:Севастополь)) was ordered as a 58-gun wooden frigate by the Imperial Russian Navy in the early 1860s, but was converted while under construction into a 32-gun armored frigate. She served in the Baltic Fleet and was reclassified as a training ship in 1880. ''Sevastopol'' was decommissioned five years later, but was not sold for scrap until 1897. ==Description== ''Sevastopol'' was long between perpendiculars, with a beam of and a draft of (forward) and (aft). She displaced and she was fitted with a blunt iron ram at her bow.〔Chesneau & Kolesnik, p. 173〕 ''Sevastopol'' was considered to be a good sea boat and her total crew numbered 607 officers and enlisted men.〔''Russian Ironclad Frigates Sevastopol and Petropavlovsk'', p. 415〕 The ship was fitted with a horizontal return-connecting-rod steam engine〔 built by the Izhora Works of Saint Petersburg.〔 It drove a single two-bladed propeller using steam that was provided by an unknown number of rectangular boilers.〔 During the ship's sea trials, the engine produced a total of and gave the ship a maximum speed of . The ship carried a maximum of of coal, but her endurance is unknown.〔Tredea & Sozea, p. 414〕 She was schooner-rigged with three masts.〔 As a heavy frigate, ''Sevastopol'' was intended to be armed with 54 of the most powerful guns available to the Russians, the 60-pounder smoothbore gun, and four long 36-pounder smoothbores. Her armament was revised when she was converted to an ironclad and she was completed with an armament of thirty-two 60-pounder guns, four on the upper deck as chase guns and 28 on the lower deck. In 1868, one chase gun and two guns on the lower deck were replaced by rifled guns and 11 more of the 60-pounders were replaced by seven 8-inch guns two years later. In 1877, her armament was changed again to 14 eight-inch guns on the lower deck and two more on the upper deck. Also mounted on the upper deck were one and ten rifled guns.〔 The entire ship's side was protected with wrought-iron armor〔 that extended below the waterline.〔Watts, p. 67〕 It was thick amidships, backed by of teak, that thinned to , backed by six inches of teak, in steps beginning from the ship's ends.〔 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 ironclad Sevastopol」の詳細全文を読む スポンサード リンク
