The USS Massachusetts (BB-2) was an Indiana-class pre-dreadnought battleship built for the United States Navy, representing an early step in American naval modernization. Constructed by William Cramp & Sons in Philadelphia, her keel was laid in 1891, and she was launched on June 10, 1893. She measured approximately 351 feet 2 inches in overall length, with a beam of 69 feet 3 inches and a draft of 24 feet. Her displacement ranged from 10,288 long tons at design to over 11,600 long tons at full load. The ship was powered by two triple-expansion steam engines and four coal-fired boilers, achieving a top speed of 15 knots and a cruising radius of 5,640 nautical miles at 10 knots. Massachusetts's armament included four 13-inch/35 caliber main guns in two twin turrets, one fore and one aft, supported by eight 8-inch/35 caliber secondary guns in four twin turrets, and six 6-inch/40 caliber guns in a casemate battery. For close defense, she carried twenty 6-pounder guns and six 1-pounder guns, along with 18-inch torpedo tubes. Her armor was substantial, with an 18-inch thick belt over critical spaces, 17-inch main battery turret sides, and a conning tower with 10-inch armor. In service, Massachusetts participated in the Spanish–American War as part of the Flying Squadron, engaging in blockades of Cienfuegos and Santiago de Cuba. She missed the Battle of Santiago de Cuba due to coal resupply delays. Her post-war service included training maneuvers with the North Atlantic Squadron, but she suffered setbacks such as an 8-inch gun turret explosion in 1903 that killed nine crew members, and two grounding incidents. She was decommissioned in 1906 for modernization, which included new boilers, guns, and structural enhancements. Despite her upgrades, by 1910 she was considered obsolete. Recommissioned in 1917 for World War I, she served as a gunnery training ship and target vessel until her final decommissioning in 1919. Her name was later reused for a newer battleship, and her hull was designated "Coast Battleship Number 2." In 1921, she was scuttled in the Gulf of Mexico and used as an artillery target. Her wreck is now part of the Florida Underwater Archaeological Preserve and listed on the National Register of Historic Places, serving as an artificial reef and popular diving site. The USS Massachusetts thus holds maritime significance as a pioneering American battleship and a symbol of naval evolution.
