The USS Missouri (BB-63) is an Iowa-class battleship built for the United States Navy during the 1940s, and she stands as the last battleship to be commissioned by the US. She measures approximately 887 feet 3 inches (270.4 meters) in overall length and 860 feet (262.1 meters) at the waterline, with a beam of 108 feet 2 inches (33 meters) and a full draft of 37 feet 9 inches (11.5 meters) at her combat load of about 57,540 long tons (58,460 tonnes). Powered by four General Electric geared steam turbines generating 212,000 shaft horsepower, she was designed for a top speed of 32.5 knots, with estimated capabilities reaching about 34 knots under overload conditions. Her cruising range was approximately 15,000 nautical miles at 15 knots. Her main armament consisted of nine 16-inch (406 mm)/50 caliber Mark 7 guns arranged in three triple turrets on the centerline, complemented by twenty 5-inch (127 mm)/38 caliber dual-purpose guns in five twin turrets amidships, and various anti-aircraft weapons including quadruple 40 mm Bofors and 20 mm Oerlikon cannons. The ship's fire-control system integrated Mark 38 directors and radar systems for precise targeting. She was equipped with two aircraft catapults on her stern for floatplanes initially carrying Vought OS2U Kingfishers, later replaced by Curtiss SC Seahawks. Constructed at the Brooklyn Navy Yard, her keel was laid in January 1941, and she was launched in January 1944 before commissioning in June of that year. Her armor features an 12.1-inch (307 mm) waterline belt and heavily armored turrets and conning tower, with main gun turrets protected by 19.5-inch (495 mm) thick plates. Her internal structure includes a double bottom and compartments designed to absorb torpedo damage. Missouri served extensively in World War II, participating in key battles such as Iwo Jima and Okinawa, and was the site where the Japanese Instrument of Surrender was signed, marking the end of the war. She also saw action during the Korean War, providing shore bombardments and serving as a flagship, and was modernized in the 1980s with missile launchers and upgraded electronics as part of the 600-ship Navy program. She participated in Operation Desert Storm in 1991, firing Tomahawk missiles and shelling Iraqi targets. Decommissioned in 1992, she now resides as a museum ship at Pearl Harbor, Hawaii, and is recognized for her historical significance, including hosting the surrender signing and her role in key maritime conflicts.
