The USS Arizona was a Pennsylvania-class battleship commissioned in the United State Navy in 1916. She went through an extensive modernization in 1929, with new deck armor, boilers, turbines, guns and fire-control. During the surprise Japanese attack on Pearl Harbor, Hawaii, on Dec. 7, 1941, a bomb may have detonated a powder magazine at the midships gun turret and the battleship exploded violently and sank, with the loss of 1,177 officers and crewmen. The U.S. made a formal declaration of war against Japan the following day. Germany and Italy then declared war on the United States, which the U.S. reciprocated on Dec. 11.

The USS Arizona still rests at the bottom of the harbor and is now part of the USS Arizona Memorial. The ship and all of her crew are memorialized at the University of Arizona Mall.
