The 50th Operations Group is a component of the 50th Space Wing, assigned to the United States Air Force Space Command. The group is stationed at Schriever Air Force Base, Colorado. The group was activated in January 1941 as the 50th Pursuit Group and began training under Third Air Force. In May 1942 it was reassigned to the Army Air Forces School of Applied Tactics, where it was a training and test unit as the 50th Fighter Group (Special). The group moved to the European Theater of Operations in the Spring 1944 expansion of Ninth Air Force in England in preparation for Operation Overlord. It few its first combat mission on 1 May 1944. The group moved to France in late June and continued in combat until V-E Day. During combat operations over Western Europe, the unit received two Distinguished Unit Citations. It returned to the United States, where it was inactivated on 7 November 1945. In June 1949 the group was activated as a reserve unit at Otis Air Force Base, Massachusetts, where it was a corollary unit of the active duty 33d Fighter Group. In 1950, it became the 50th Fighter-Interceptor Group. The group was called to active duty in connection with the Korean War in June 1950, but was inactivated a few days later and its personnel were transferred to other units. The group, now designated the 50th Fighter-Bomber Group, was activated in January 1953, when it took over the mission, personnel and equipment of the 140th Fighter-Bomber Group, a Colorado Air National Guard unit that had been federalized for the Korean War. Once the group transitioned from North American F-51 Mustangs to North American F-86 Sabres, it deployed to Germany and Hahn Air Base. It moved to Toul-Rosières Air Base, France in 1956, and was inactivated there in late 1957. Although the group was renamed the 50th Tactical Fighter Group in 1985, it remained inactive until December 1991, when, as the 50th Operations Group, it took over the personnel of the 1002d Operations Group, which was simultaneously inactivated. Since then, the group has managed a variety of surveillance and communications satellites for the Department of Defense. ==Overview== The 50th Operations Group stood up at Falcon Air Force Base 30 January 1992, the same day as its parent, the 50th Space Wing. Its crews, formerly the crews of the 1002d Operations Group, monitored satellites during launch operations, maneuvered them into proper orbits and maintained their health in space. The group commands, controls and executes launch and early orbit operations, and provides operational support for over 65 satellites which support the president, the secretary of defense, other government agencies, and United States and allied military forces. It comprises over 1,100 active duty, reserve, and civilians. It trains the more than 500 system operators that form its space operations crews.〔 The group's space operations centers track, monitor telemetry and command satellites during launch, early-orbit and on-orbit operations. They resolve anomalies with satellites when they occur and dispose of the satellites when missions are terminated.〔 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「50th Operations Group」の詳細全文を読む スポンサード リンク
