Russian battleship Ekaterina II
''Ekaterina II'' ((ロシア語:Екатерина II) ''Catherine II of Russia'') was the lead ship of the pre-dreadnought battleships built for the Imperial Russian Navy in the 1880s. Her crew was considered unreliable when the crew of the battleship mutinied in June 1905 and her engines were decoupled from the propellers to prevent her from joining ''Potemkin''. She was turned over to the Sevastopol port authorities before being stricken on 14 August 1907. She was re-designated as ''Stricken Vessel Nr. 3'' on 22 April 1912 before being sunk as a torpedo target for the Black Sea Fleet.

''Ekaterina II'' differed from her sisters mainly in her gun mounts. Her guns used bulky, hydraulically powered Moncrieff disappearing gun mounts. They had a rate of fire of five minutes, ten seconds between aimed rounds. Each of the forward mounts could traverse 30° across the bow and 35° abaft the beam, or a total of 155°. 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. The seven Obukhov Model 1877 35-calibre guns were mounted on broadside pivot mounts in hull embrasures, except for one gun mounted in the stern in the hull. Six of the eight five-barrelled revolving Hotchkiss guns were mounted in small sponsons that projected from the hull with the aftermost pair mounted in embrasures in the hull to defend the ship against torpedo boats. Four five-barrelled 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 mounted on each broadside forward and aft of the central citadel and the seventh tube was in the stern.
