USS Arizona (BB-39) was a Pennsylvania-class battleship of the United States Navy, commissioned in 1916 and best known for being sunk during the Japanese attack on Pearl Harbor on 7 December 1941. The wreck remains at Pearl Harbor as a war grave, and the USS Arizona Memorial was built above it to honour those killed in the attack. The ship is primarily significant to Canadian readers as part of the broader Pacific war history and the Pearl Harbor attack that led the United States into World War II, affecting Canada’s wartime alliance and Pacific theatre context.

Design and construction

USS Arizona was built at the New York Navy Yard and named for the 48th state, Arizona. It was launched in 1915 and commissioned in 1916 as the second ship of the Pennsylvania class.

Service before Pearl Harbor

Before 1941, Arizona served with the U.S. Atlantic Fleet and later the Pacific Fleet. It underwent modernization in the late 1920s and early 1930s before being based at Pearl Harbor.

Attack and sinking

During the Japanese attack on Pearl Harbor, Arizona was hit by armor-piercing bombs that ignited the forward ammunition magazines. The resulting explosion destroyed the ship and killed 1,177 crew members.

Memorial and wreck site

Arizona was not repaired after the attack, and the wreck remains at Pearl Harbor as a historic site and war grave. The USS Arizona Memorial was built over the wreck and serves as a place of remembrance.
