The wreck of "Arizona" remains at Pearl Harbor to commemorate the men of her crew lost that December morning in 1941. On 7 March 1950, Admiral Arthur W. Radford, commander in chief of the Pacific Fleet at that time, instituted the raising of colors over her remains. Legislation during the administrations of presidents Dwight D. Eisenhower and John F. Kennedy resulted in the designation of the wreck as a national shrine in 1962. A memorial was built across the ship's sunken remains, including a shrine room listing the names of the lost crew members on a marble wall. The national memorial was administratively listed on the National Register of Historic Places on 15 October 1966. The ship herself was designated a National Historic Landmark on 5 May 1989. Upon their death, survivors of the attack may have their ashes placed within the ship, among their fallen comrades. Veterans who served aboard the ship at other times may have their ashes scattered in the water above the ship.
