From Wikipedia:USS Arizona was a Pennsylvania-class battleship built for the United States Navy in the mid-1910s. Arizona was bombed during the Japanese attack on Pearl Harbor on 7 December 1941. After a bomb detonated in a powder magazine, the battleship exploded violently and sank, with the loss of 1,177 officers and crewmen.The Pennsylvania-class ships were significantly larger than their predecessors, the Nevada class. Arizona had an overall length of 608 feet (185.3 m), a beam of 97 feet (29.6 m) (at the waterline), and a draft of 29 feet 3 inches (8.9 m) at deep load. This was 25 feet (7.6 m) longer than the older ships. She displaced 29,158 long tons (29,626 t) at standard and 31,917 long tons (32,429 t) at deep load, over 4,000 long tons (4,060 t) more than the older ships. The ship had a metacentric height of 7.82 feet (2.4 m) at deep load. Her crew numbered 56 officers and 1,031 enlisted men as built. The Pennsylvania-class design continued the all-or-nothing principle of armoring only the most important areas of the ship begun in the Nevada class.
