The USS South Dakota (BB-57) was the lead ship of the South Dakota-class fast battleships constructed for the United States Navy in the 1930s. Measuring approximately 680 feet in length overall, she was powered by four General Electric steam turbines and eight oil-fired Babcock & Wilcox boilers, generating 130,000 shaft horsepower, which allowed her to reach a top speed of 27.5 knots. Her beam was 108 feet 2 inches, with a draft of 35 feet 1 inch, and her displacement was 37,970 long tons at design load, increasing to over 44,500 long tons at full combat load. Built at the New York Shipbuilding Corporation in Camden, New Jersey, her keel was laid in July 1939, and she was launched in June 1941. She was commissioned in March 1942, with Captain Thomas Leigh Gatch at the helm. Her main armament comprised nine 16-inch/45 caliber Mark 6 guns in three triple turrets, and her secondary armament included sixteen 5-inch/38 caliber dual-purpose guns. Her armor was substantial, with an 18-inch thick face on her main battery turrets, a 12.2-inch thick belt, and up to 6-inch thick armored decks. South Dakota saw extensive service during World War II, beginning with her deployment to the South Pacific in 1942. She participated in key battles including the Guadalcanal campaign, notably the Battle of Santa Cruz and the Second Naval Battle of Guadalcanal, where she sustained over two dozen hits but remained afloat. Notably, during the Battle of the Philippine Sea in 1944, she was hit by a Japanese bomb, which caused significant damage, killed 24 crew members, and wounded 27. She also took part in various operations supporting island invasions across the Pacific, including Iwo Jima, Okinawa, and strikes against Japan itself. After the war, she served as a flagship during the initial occupation of Japan before returning to the U.S. in late 1945. She was decommissioned in January 1947 and placed in reserve. Despite plans for modernization and conversion into a guided missile battleship, these were never realized. She was stricken from the Naval Vessel Register in 1962 and sold for scrap. Today, artifacts from USS South Dakota are preserved in memorials and museums, including her bell, a section of armor plate, and a simulated gun turret, honoring her distinguished wartime service.
