Following the North Korean invasion of South Korea in June 1950, and the ensuing intervention by United Nations forces, the U.S. Navy began reactivating warships and auxiliaries to support the greatly expanded duties of the Department of Defense. As part of this effort, "Firedrake" recommissioned at Orange, Texas, on 11 October 1951, Capt. Warner S. Rodimen in command. After fitting out at Beaumont, Texas, and then undergoing refresher training at San Diego, California, "Firedrake" steamed to her new home port of San Francisco for duty with Mobile Logistics Support Group Able (TG 92.1). Her first Western Pacific (WestPac) tour (29 February - 24 August 1952) took the ammunition ship to Korean waters, where she supplied ammunition to the aircraft carriers and warships operating off Korea in the Sea of Japan and the Yellow Sea. A second WestPac tour off Korea followed six months later (4 February - 30 September 1953), with the focus again that of supplying aircraft carriers with ordnance.
