''Imperator Aleksandr II'' ((ロシア語:Император Александр II)) was a battleship built for the Imperial Russian Navy in the 1880s. She was an artillery training ship assigned to the Baltic Fleet by the time of the Russo-Japanese War of 1905 and was not sent to the Pacific as was most of the rest of the Baltic Fleet. She was inactive at Kronstadt during World War I, but her crew was active in the revolutionary movement. She was turned over to the Kronstadt port authority on 21 April 1921 before she was sold for scrap on 22 August 1922. She was towed to Germany during the autumn of 1922, but was not stricken from the Navy List until 21 November 1925. ==Description== ''Imperator Aleksandr II'' was named after the Emperor Alexander II of Russia.

The four Obukhov Model 1877 35-calibre guns were on center-pivot mounts in casemates at the corners of the citadel, the hull being recessed to increase their arcs of fire ahead or behind. The eight Model 1877 35-calibre guns were mounted on broadside pivot mounts. Four were fitted between the 9-inch guns and could traverse a total of 100°. The others were mounted at each end of the ship where they could fire directly ahead or astern. The ten Hotchkiss revolving cannon were mounted in hull embrasures of the ship, between the nine and six-inch guns to defend against torpedo boats. Four Hotchkiss revolving cannon were mounted in each fighting top. ''Imperator Aleksandr II'' carried five above-water torpedo tubes. Two in the bow, one on each side of the stempost, one tube on each broadside and a tube in the stern. Smaller torpedo tubes could be mounted in four of the ship's cutters. 36 mines could also be carried.〔McLaughlin, p. 35〕 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 Imperator Aleksandr II」の詳細全文を読む スポンサード リンク
