Welcome to the USS Massachusetts Living History Group, USS Massachusetts (BB-59), known as "Big Mamie" to her crewmembers during World War II, was a battleship of the second South Dakota-class. She was the seventh ship of the United States Navy to be named in honor of the sixth state, and one of two ships of her class (along with along with her sister Alabama) to be donated for use as a museum ship. Among the ships armed with 16 inch guns during World War II, Massachusetts stands out because it is believed that she may have fired the US Navy's first and last 16 in (410 mm) shells of the war.
During World War II Massachusetts was initially assigned to duty in the Atlantic Fleet, and exchanged shots with Vichy French battleship Jean Bart during Operation Torch. Transferred to the Pacific fleet in 1943, Massachusetts participated in the Solomon Islands campaign and the Philippines Campaign, and in the latter campaign took part in the Battle of Leyte Gulf. In 1945 she was one of several ships assigned to shell targets on Honshu, one of the Japanese Home Islands.
