USS Tennessee (BB-43) was an American battleship laid down in 1917, launched in April 1919, and commissioned in the US Navy in June 1920. The length of the ship was 190 m, width 29.7 m, and full displacement - at the time of launching - 33,700 tons. The maximum speed of the USS Tennessee battleship was up to 21 knots. The main armament was 12 356 mm guns in four turrets, three cannons each, and the secondary armament was primarily 14 127 mm guns.
USS Tennessee was the first of two battleships of the same type. Units of this type belonged to the so-called standard battleships, i.e. ships with similar combat values, dimensions and capabilities, although divided into different classes, which entered service with the US Navy in the period 1916-1923. The Tennessee-class battleships, compared to their predecessors, had more perfect fire control systems, significantly improved hull anti-torpedo protection and improved ergonomics of the main weapons turrets, increasing their firing range. USS Tennessee (BB-43) in the interwar period was assigned to the Pacific Fleet, as part of which it carried out numerous exercises and cruises in the Pacific Ocean. At the outbreak of World War II in the Pacific, the USS Tennessee was in the base at Pearl Harbor, but Japanese air strikes only caused light damage to the battleship. At the beginning of 1942, the ship underwent necessary repairs, but also underwent modernization, strengthening anti-aircraft weapons and installing artillery fire control radar. In June 1943, he supported the American operations in the Aleutians, and in November of the same year - the landing of the U.S. Marines in Tarawa. At the beginning of the following year, he supported with his fire the troops storming the islands of the Marshall Archipelago. In 1945, however, he fought in the area of Iwo-Jima and Okinawa. The USS Tennessee (BB-43) was decommissioned in 1947 and was sold for scrap in 1959.
