Aerospace Defense Command (Air Defense Command before 1968) was a Cold War military organization established as one of the initial United States Air Forces major commands. Activated in 1946 by the United States Army Air Force, its mission was to organize and administer the integrated air defense system of the Continental United States (CONUS), exercise direct control of all active measures, and coordinate all passive means of air defense. ==Overview== During the 1946 transition to an independent Air Force military branch, the United States Army Air Forces activated Air Defense Command (ADC) with a Numbered Air Force of the former Continental Air Forces, from which it took its mission of air warning and air defense. After the 1947 USAF transfer, ADC become part of Continental Air Command (ConAC) on 1 December 1948. ConAC gradually assumed direct charge of ADC air defense components and ADC inactivated on 1 July 1950 at the beginning of the Korean War. On 10 November 1950, Generals Vandenberg and Twining notified General Whitehead that "the Air Force had approved activation of a separate Air Defense Command (CONAC ) with headquarters on Ent" with the mission to stop a handful of conventionally armed piston engine-powered bombers on a one-way mission. With advances in USSR bombers, ADC completed improved radar networks and manned interceptors in the 1950s, and at the end of the decade computerized Air Defense Direction Centers to allow air defense controllers to more quickly review integrated military air defense warning (MADW) data and dispatch defenses (e.g., surface-to-air missiles in 1959). ADC began missile warning and space surveillance missions in 1960 and 1961, established a temporary missile warning network for the 1962 Cuban Missile Crisis, and in 1968 was redesignated Aerospace Defense Command (ADCOM). In 1975, ADCOM became a specified command and the United States' executive agent in the North American Air Defense Command—the single CINCNORAD/CINCAD commanded both. ADCOM's last surface-to-air missiles were taken off alert in 1972, and the Federal Aviation Administration took over many of ADCOM's SAGE radar stations. In 1979 the number of manned interceptors had dropped to tbd, and on 1 October 1979 ADCOM interceptors/bases and remaining air warning radar stations transferred to Tactical Air Command. ADCOM's missile warning and space surveillance installations transferred in 1979 to SAC/SX,) and the Air Force Element, NORAD/ADCOM (AFENA) was redesignated the Aerospace Defense Center. Within a few years, the Aerospace Defense Center, the ADCOM specified command organizations, along with SAC's missile warning and space surveillance installations became part of the 1982 Space Command which activated its headquarters in the same building where ADCOM had been inactivated on 31 March 1980. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Aerospace Defense Command」の詳細全文を読む スポンサード リンク
