USS Salt Lake City, a 9100-ton Pensacola class heavy cruiser built at Camden, New Jersey, was commissioned in December 1929. In 1945, Salt Lake City participated in the Iwo Jima and Okinawa campaigns. After the fighting ended in August, she supported the Occupation of Japan and "Magic Carpet" operations to transport American servicemen back to the U.S. The now-elderly cruiser was then placed in relatively inactive status until sent to serve as a target during the July 1946 atomic bomb tests at Bikini Atoll. Left severely damaged by this experience, USS Salt Lake City was decommissioned a month later. She was sunk as a target for conventional weapons in May 1948.
