Alaskan Air Command (AAC) is an inactive United States Air Force Major Command originally established in 1942 under the United States Army Air Forces. Its mission was to organize and administer the air defense system of Alaska, exercise direct control of all active measures, and coordinate all passive means of air defense. In addition, the command also supported Strategic Air Command elements operating through and around Alaska. It was redesignated Eleventh Air Force on 9 August 1990 and, concurrently, status changed from a major command of the United States Air Force to a subordinate organization of Pacific Air Forces. History Establishment Established on 18 December 1945 the end of World War II, assuming jurisdiction of former Eleventh Air Force, assets in the Alaska Territory. Headquartered at Davis Army Airfield on Adak, the initial mission of AAC was the consolidation of wartime Army Air Forces in Alaska and training of those forces remaining after demobilization. Its headquarters was moved back to Anchorage, and was re-established at Elmendorf Field on 1 October 1946. As well as the reorganization of the command and control echelon in Alaska, the 343d Fighter Group at Shemya AAF was inactivated, replaced by the 57th Fighter Group in keeping with the Air Forces policy of retaining low-numbered units on active duty following the war. The 57th FG was equipped with 3 squadrons of very-long range P-51H Mustangs, originally designed for escort missions of B-29 Superfortresses during the war from the Mariana Islands to Japan and back. Two of its squadrons the 64th and 66th were located at Shemya; the 65th at Ladd Field, near Fairbanks. The 449th Fighter Squadron (All Weather) was activated at Davis AFB on 1 September 1947. It was equipped with P-61 Black Widows and assigned directly to Headquarters, AAC. The only other flying unit was the 54th Troop Carrier Squadron at Elmendorf Field. Despite the wartime military campaign carried out in the Aleutian Islands, the archipelago was viewed as having little military value, other than refueling transport aircraft on the Great Circle Route from Japan. It was believed that Alaska was threatened more by Soviet bomber attacks across the polar regions. Shortly after the Japanese Capitulation, most airfields in the Aleutians were placed in a standby status. Headquarters, Alaskan Air Command was moved to Elmendorf Field on 1 October 1946. The Aleutian Sector was inactivated on 1 July 1947. Following the National Security Act
