USS Arizona was a Pennsylvania-class battleship built for and by the United States Navy in the mid-1910s. Named in honour of the 48th state's recent admission into the union, the ship was the second and last of the Pennsylvania class of "super-dreadnought" battleships.
During the Japanese attack on Pearl Harbor on 7 December 1941, Arizona was bombed. She exploded and sank, killing 1,177 officers and crewmen. Unlike many of the other ships sunk or damaged that day, Arizona could not be fully salvaged, though the navy removed parts of the ship for reuse. The wreck still lies at the bottom of Pearl Harbor and the USS Arizona Memorial, dedicated on 30 May 1962 to all those who died during the attack, straddles the ship's hull.
