Twentieth Air Force
Constituted as Twentieth AF on 4 Apr 1944 and activated the same day. Some combat elements moved in the summer of 1944 from the US to India where they carried out very heavy bombardment operations against targets in Japan, Formosa, Thailand, and Burma. Other combat elements began moving late in 1944 from the US to the Marianas, being joined there early in 1945 by the elements that had been in India. Headquarters, which had remained in the US, was transferred to Guam in Jul 1945. From the Marianas the Twentieth conducted a strategic air offensive that was climaxed by the dropping of two atomic bombs on Japan. After the war the Twentieth remained in the theater and eventually became part of Far East Air Forces. Served in combat for a short time at the beginning of the Korean War but later was concerned primarily with logistic support for the operations of other organizations and with air defense for the Ryukyus. Inactivated on Okinawa on 1 Mar 1955.
