USS Arizona (BB-39) was a Pennsylvania-class battleship of the United States Navy and the first to be named "Arizona". On March 4, 1913, Congress authorized the construction of Arizona, named to honor the 48th state's admission into the union on 14 February 1912. The ship was the second and last of the Pennsylvania class of "super-dreadnought" battleships. Her keel was laid at the Brooklyn Navy Yard on 16 March 1914. She was launched on 19 June 1915, sponsored by Esther Ross, the daughter of a prominent Arizona pioneer, W.W. Ross of Prescott, Arizona. The ship's remaining machinery, including new Parson turbines, was installed, and she was commissioned at her builder's yard on 17 October 1916, with Captain John D. McDonald in command.
Arizona served stateside during World War I. She is most remembered because of her sinking, with the loss of 1,177 lives, during the Japanese attack on Pearl Harbor on 7 December 1941, the event that goaded the US into World War II. Unlike most of the other ships sunk or damaged that day, the Arizona could not be salvaged, although the U.S. Navy removed several elements of the ship that were reused. The wreck still lies at the bottom of Pearl Harbor and was established as a memorial to all those who died during the Pearl Harbor attack.
