USS Massachusetts (BB-2) is an Indiana-class battleship and the second United States Navy ship comparable to foreign battleships of its time. Today she is a diving site off Pensacola, Florida.

 

USS Massachusetts - June 1901

Authorized in 1890 and commissioned six years later, she was a small battleship, though with heavy armor and ordnance. The ship class also pioneered the use of an intermediate battery. She was designed for coastal defense and as a result, her decks were not safe from high waves on the open ocean.

Massachusetts served in the Spanish–American War (1898) as part of the Flying Squadron and took part in the blockades of Cienfuegos and Santiago de Cuba. She missed the decisive Battle of Santiago de Cuba after steaming to Guantánamo Bay the night before to resupply coal. After the war she served with the North Atlantic Squadron, performing training maneuvers and gunnery practice. During this period she suffered an explosion in an 8-inch gun turret, killing nine, and ran aground twice, requiring several months of repair both times. She was decommissioned in 1906 for modernization.

Although considered obsolete in 1910, the battleship was recommissioned and used for annual cruises for midshipmen during the summers and otherwise laid up in the reserve fleet until her decommissioning in 1914. In 1917 she was recommissioned to serve as a training ship for gun crews during World War I. She was decommissioned for the final time in March 1919 under the name Coast Battleship Number 2 so that her name could be reused for USS Massachusetts (BB-54). In 1921 she was scuttled in shallow water in the Gulf of Mexico off Pensacola and used as a target for experimental artillery. The wreck was never scrapped and in 1956 it was declared the property of the State of Florida. Since 1993 the wreck has been a Florida Underwater Archaeological Preserve and it is included in the National Register of Historic Places. It serves as an artificial reef and diving spot.
