The USS Mississippi (BB-41) was a prominent New Mexico-class battleship built for the United States Navy, laid down in April 1915 at Newport News Shipbuilding and launched in January 1917. She measured 624 feet (190 meters) in length overall, with a beam of approximately 97 feet 5 inches (29.69 meters) and a draft of 30 feet (9.1 meters). Displacing around 32,000 long tons (32,514 metric tons) at design load, her full combat load reached approximately 33,000 long tons (33,530 metric tons). Powered by four Curtis turbines and nine oil-fired Babcock & Wilcox boilers rated at 32,000 shaft horsepower, she could reach speeds of 21 knots (39 km/h). Her range was about 8,000 nautical miles at 10 knots, supporting extended operations across the Atlantic and Pacific theaters. Armament comprised twelve 14-inch (356 mm)/50-caliber guns arranged in four triple turrets, with the main battery mounted on the centerline, two superfiring forward and two aft. Her secondary armament included fourteen 5-inch (127 mm)/51-caliber guns in casemates, supplemented by four 3-inch (76 mm)/50-caliber guns and two submerged 21-inch (530 mm) torpedo tubes. The ship's heavy armor protection featured a main belt ranging from 8 to 13.5 inches (203–343 mm), a deck up to 3.5 inches (89 mm) thick, and turret faces of 18 inches (457 mm). The conning tower was protected by 16 inches (406 mm) of armor. Mississippi saw service initially in North American waters during World War I, primarily conducting training exercises. In the 1920s and 1930s, she was part of the Pacific Fleet, participating in fleet problems and gunnery exercises, and undergoing significant modernization that improved her turbines, armament, and armor. Notably, her main turrets were adapted for greater elevation, and anti-aircraft weaponry was added. During World War II, Mississippi was transferred to the Atlantic, then returned to the Pacific, where she supported amphibious operations across the Gilbert and Marshall Islands, the Philippines, Peleliu, and Okinawa. She participated in the historic Battle of Surigao Strait, the last battleship engagement in history, firing a decisive salvo during the Battle of Leyte Gulf. She survived kamikaze hits at Luzon and Okinawa, continuing to shell Japanese defenses until the end of hostilities. Post-war, she was converted into a gunnery training ship and used for missile testing, including early trials of the Terrier missile. Decommissioned in 1956 and sold for scrap, her legacy lies in her extensive combat record and role in modernizing naval warfare tactics.
