Commissioned too late to take an active part in World War II, Bairoko engaged in peacetime fleet cruises, maneuvers, and exercises until December 1949. During the period she made two cruises to the Far East (18 October 1945-25 January 1946 and 18 February-30 May 19471, and participated in the atomic bomb test at Eniwetok Atoll. On 15 December 1949 she reported to San Francisco for pre inactivation overhaul and went out of commission in reserve 14 April 1950.
When the Korean conflict broke out Bairoko was immediately readied for active duty. She was recommissioned 12 September 1950 and reported to the Pacific Fleet. Between November 1950 and August 1953 she made three extended cruises to the Far East (14 November 1950-15 August 1951, 1 December 1951-9 June 1952 and February-August 1953), acting in support of the United Nations Forces in Korea. Her planes flew hundreds of strikes against North Korean and "Chinese Volunteer" troops, installations, transportation facilities, and naval units. On 9 May 1951 she had five men killed and 13 injured by an explosion and flash fire in Japanese waters.
Returning to the west coast late in August 1953, Bairoko remained there until January 1954 when she departed to assist in the hydrogen bomb tests in the Eniwetok-Bikini area. From May through June 1954 she operated out of San Diego on training exercise~. In July 1954 she reported to Long Beach Naval Shipyard to commence preinactivation overhaul and went out of commission in reserve at San Francisco 18 February 1955.
