USS Massachusetts

USS Massachusetts is the third of four South Dakota-class fast battleships built for the United States Navy in the late 1930s. The first American battleships designed after the Washington treaty system began to break down in the mid-1930s, they took advantage of an escalator clause that allowed increasing the main battery to 16-inch guns, but refusal to authorize larger battleships kept their displacement close to the Washington limit of 35,000 long tons. A requirement to be armored against the same caliber of guns as they carried, combined with the displacement restriction, resulted in cramped ships, a problem that was exacerbated by wartime modifications that considerably strengthened their anti-aircraft batteries and significantly increased their crews.

On completion, Massachusetts was sent to support Operation Torch, the invasion of French North Africa, in November 1942. There, she engaged in an artillery duel with the incomplete French battleship Jean Bart and neutralized her.
