USS Maryland (BB-46), also known as "Old Mary" or "Fighting Mary" to her crewmates, was a Colorado-class battleship. She was the third ship of the United States Navy to be named in honor of the seventh state. She was commissioned in 1921 and, serving as the flagship of the fleet, cruised to Australia, New Zealand and Brazil.
She is most notable for her service in World War II. She was present on Battleship Row during the Attack on Pearl Harbor, and was lightly damaged by Japanese bombs. Returning to duty in 1942, she saw service in the Pacific War, first supporting the rest of the fleet at the Battle of Midway, and then patrolling the Fiji Islands to guard against Japanese incursion. Next, she went on the offensive, commencing shore bombardments in the Battle of Tarawa and later in the Battle of Kwajalein. During the Battle of Saipan she took torpedo damage to her bow, necessitating repairs and refits. She then participated in the Battle of Leyte Gulf where she was hit by a kamikaze. She took another kamikaze hit at the Battle of Okinawa, and was under repair at the end of World War II. (Wiki)
