Main article: USS Massachusetts (BB-59)
The largest vessel in the Battleship Cove fleet, the battleship USS Massachusetts (BB-59) is the centerpiece of the collection.
Known as "Big Mamie" to her crewmembers during World War II, a battleship of the second South Dakota class, was the seventh ship of the United States Navy to be named in honor of the sixth state.
Her keel was laid down 20 July 1939 at the Fore River Shipyard of Quincy, Massachusetts.
She was launched on 23 September 1941 sponsored by Mrs. Charles Francis Adams III, and commissioned on 12 May 1942 at Boston, Massachusetts, with Captain Francis E. M. Whiting in command.

Massachusetts received eleven battle stars for World War II service and earned a reputation as a "Work Horse of the Fleet".
During World War II, no United States Navy personnel were killed in action while aboard Massachusetts.
It is said that "Big Mamie" fired both the first US Navy 16-inch (406 mm) shells of World War II (at the Vichy French battleship Jean Bart in the Naval Battle of Casablanca during Operation Torch); and the last (at a Japanese steel works at Hamamatsu), hours before the war ended.

USS Massachusetts is one of eight United States battleships remaining of the many that were produced in the first half of the 20th century.
