The Pennsylvania-class of battleships were two battleships produced and used by the United States Navy just before World War I. Coming with significant developments in dreadnought design, such as an additional two 14-inch guns and more underwater protection, the two vessels experienced little combat during World War I, and was shifted to the Pacific during the interwar period. Both ships were present in Battleship Row during the Attack on Pearl Harbor, and USS Arizona was sunk after its ammunition magazine was breached by a Japanese bomb. USS Pennsylvania remained with the fleet until the end of the war when it was destroyed by nuclear testing at Bikini Atoll.
