The Russian battleship Poltava was a prominent pre-dreadnought vessel of the Petropavlovsk class, constructed in the 1890s for the Imperial Russian Navy. She measured 376 feet (114.6 meters) in length overall, with a beam of 70 feet (21.3 meters) and a draft of 28 feet 3 inches (8.6 meters). Designed to displace approximately 10,960 long tons (11,140 metric tons), Poltava was actually completed weighing around 11,500 long tons (11,700 metric tons), making her somewhat overweight. Her propulsion system comprised two British-built vertical triple-expansion steam engines, each driving a shaft, powered by 14 cylindrical boilers. During sea trials, she achieved a top speed of 16.29 knots, slightly exceeding her designed speed of 16 knots, and had a range of about 3,750 nautical miles at 10 knots. Her crew complement ranged between 26 to 27 officers and 605 to 625 enlisted men. Poltava's armament was formidable for her time, featuring four 12-inch (305 mm) main guns mounted in twin turrets—one forward and one aft—capable of firing one round every 90 seconds, although in practice at half that rate. Her secondary armament included twelve 6-inch (152 mm) quick-fire guns, with eight housed in wing turrets and four in unprotected hull embrasures. Smaller defensive weapons included twelve 47 mm and twenty-eight 37 mm guns, along with six torpedo tubes—four above water (15-inch/381 mm) and two submerged (18-inch/457 mm). She also carried 50 mines for harbor defense. Poltava was the first Russian battleship to incorporate Krupp cemented armor, with her waterline belt up to 14.5 inches (368 mm) thick, and main gun turrets with armor up to 10 inches (254 mm). Named after the victory at the 1709 Battle of Poltava, her construction was delayed by shortages, design modifications, and late delivery of her main armament. Laid down in 1892 at the New Admiralty Shipyard and launched in 1894, her trials lasted until 1899. She was initially assigned to the Baltic Fleet but soon transferred to the Pacific Squadron, arriving at Port Arthur in 1901. During the Russo-Japanese War, Poltava participated in key engagements, including the Battle of Port Arthur and the Battle of the Yellow Sea, where she sustained significant damage and was ultimately sunk by Japanese artillery during the siege of Port Arthur in December 1904. Raised by the Japanese, she was renamed Tango and served in the IJN, undergoing several modifications. She later returned to Russia in 1916, renamed Chesma, and participated in the siege of Qingdao during World War I. Her service continued through the Russian Civil War, ending as a prison hulk before being scrapped in 1924, marking her as a vessel of considerable historical maritime significance due to her extensive combat record and technological innovations.
