The Russian battleship ''Poltava'' ((ロシア語:Полтава)) was one of three pre-dreadnought battleships built for the Imperial Russian Navy in the 1890s. The ship was transferred to the Pacific Squadron shortly after completion and based at Port Arthur from 1901. During the Russo-Japanese War of 1904–05, she participated in the Battle of Port Arthur and was heavily damaged during the Battle of the Yellow Sea. She was sunk by Japanese artillery during the subsequent Siege of Port Arthur in December 1904, but was raised by the Imperial Japanese Navy (IJN) after the war and renamed ''Tango'' (丹後). During World War I, she bombarded German fortifications during the Siege of Tsingtao. The Japanese government sold ''Tango'' back to the Russians at their request in 1916. She was renamed ''Chesma'' (Чесма) as her former name had been given to a new ship. En route to the White Sea, she joined an Allied force that persuaded the Greek government to disarm their ships. Her crew declared for the Bolsheviks in October 1917, but made no effort to resist when the British decided to intervene in the Russian Civil War in early 1918. In poor condition, the ship was used as a prison hulk. Abandoned by the British when they withdrew in 1919 and recaptured by the Bolsheviks, she was scrapped in 1924. == Description == ''Poltava'' was long overall, with a beam of and a draft of . Designed to displace , she was over overweight and displaced when completed. The ship was powered by two vertical triple-expansion steam engines, built by the British firm of Humphrys, Tennant and Dykes, each driving one shaft, using steam generated by 14 cylindrical fire-tube boilers. The engines were rated at and designed to reach a top speed of , but ''Poltava'' reached a speed of from during her sea trials. She carried a maximum of of coal which allowed her to steam for at a speed of . Her crew consisted of 26–27 officers and 605–625 enlisted men. The ship's main battery consisted of four guns mounted in two twin-gun turrets, one forward and one aft of the superstructure. Designed to fire one round per 90 seconds, the actual rate of fire was half that. The secondary armament consisted of twelve Canet quick-firing (QF) guns. Eight of these were mounted in four twin-gun wing turrets and the remaining guns were positioned in unprotected embrasures on the sides of the hull amidships. Smaller guns were carried for defense against torpedo boats. These included a dozen QF Hotchkiss guns and twenty-eight guns. She was also armed with six torpedo tubes, four tubes above water and two submerged tubes, all mounted on the broadside. She carried 50 mines to be used to protect her anchorage. ''Poltava'' was the first Russian battleship to use Krupp cemented armor, from Germany. Her waterline armor belt was thick. The Krupp armor of her main gun turrets had a maximum thickness of and her secondary gun turrets were protected by of armor. The nickel steel armor of her protective decks ranged from in thickness and the sides of her conning tower were thick. 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 Poltava (1894)」の詳細全文を読む スポンサード リンク
