The 89th Operations Group (89 OG) is the operational flying component of the United States Air Force 89th Airlift Wing. It is stationed at Andrews Air Force Base, Maryland.
The 89 OG provides Special Air Mission (SAM) transport to high U.S. government officials and foreign dignitaries as needed. The group provided SAM transport to the President of the United States until 20 February 2001 when that mission was delegated to the Presidential Airlift Group.
Its World War II predecessor unit, the 89th Troop Carrier Group was a First Air Force training unit providing transition training for pilots, 1942–1944, then briefly became a replacement training unit (RTU) during 1944 when it was inactivated. It trained in the Air Force Reserve for troop carrier operations, June 1949-May 1951, when it was briefly called into active service in May 1951 to provide personnel to other units during the Korean War. Reactivated in 1952 and trained in the Reserve for Tactical Air Command fighter-bomber operations until being inactivated in 1957.
