USS Arizona BB-39 Statistics


Arizona was the most heavily damaged of all the vessels in Battleship Row, suffering three near-misses and four direct-hits from 800-kg bombs dropped by high-altitude Kates. The last bomb to strike her penetrated her deck starboard of turret two and detonated within a 14-inch powder magazine. The resulting massive explosion broke the ship in two forward of turret one, collapsed her forecastle decks, and created such a cavity that her forward turrets and conning tower fell thirty feet into her hull. She was a total loss. Never seriously considered a candidate for salvage, her top-hamper was removed in 1942 and she remains where she sank to this day, a tomb for 945 men who died with her.
