Las Vegas Victory, a cargo ship, was launched 1944, by Permanente Metals Corporation, Richmond, California; sponsored by Mrs. E. W. Cragin; acquired by the Navy 25 October 1944, and commissioned the same day.
From January to March 1945, Las Vegas Victory shuttled ammunition among the Caroline Islands and the Marshall Islands, and replenished the fighting ships as they moved closer to the Japanese homeland. Departing Ulithi 25 March, she sailed for the rendezvous with units heading for Okinawa. Making her way through submarine infested waters, the cargo ship arrived off Okinawa on the 31st, and replenished two escort carriers with ammunition.
On 1 April the invasion of Okinawa started the removal of the last barrier "on the road to Japan". Under constant attack by Japanese suicide pilots, Las Vegas Victory passed ammunition to battleships, aircraft carriers, destroyers, and LCT's until late May. Arriving San Pedro, Leyte, 10 June, she loaded more ammunition and sailed for Eniwetok 19 July.
Upon her arrival 1 week later, she was assigned to the Pacific Service Force. Las Vegas Victory supported American forces in the Pacific Ocean until 7 November when she departed Eniwetok for the United States.
