A photographic guide to the USS Arizona, which exploded and sank in Pearl Harbor on December 7, 1941. A battleship of the Pennsylvania class, USS Arizona is most famous for her disastrous loss, along with over 1,000 of her men, during the surprise attack at Pearl Harbor. Armed with 12 14-inch guns, and numerous smaller weapons, Arizona was one of the most powerful warships in the world when commissioned in 1917. This volume illustrates the modifications and improvements made to the ship during her service, and her subsequent loss and partial salvage. Today the battleship remains on the bottom of Pearl Harbor, spanned by a memorial to the sacrifice of her men.
