History of West Mesa Air Force Station

Established in 1956 and became operational on 22 Jun 1956 as West Mesa Air Force Station manned by the 687th AC&W Squadron. The station initially had both a Ground-Control Intercept (GCI) and early warning mission. The early warning mission involved tracking and identifying all aircraft entering their airspace while the GCI mission involved guiding Air Force interceptors to any identified enemy aircraft. Controllers at the station vectored fighter aircraft at the correct course and speed to intercept enemy aircraft using voice commands via ground-to-air radio.

West Mesa Air Force Station served as a Master Direction Center as a part of the integrated air defense system. The 687th AC&W Squadron maintained operational control over the 767th, 768th and the 769th AC&W squadrons.

Initial equipment included the mobile MPS-7 search radar and mobile MPS-14 height-finder radar. The search radar was upgraded to fixed FPS-20A about 1961 and to an FPS-91A around 1966.

Gap Fillers

West Mesa AFS was responsible for the maintenance of one remote unattended gap-filler radar site. Gap filler sites were placed in locations where the main search radar lacked coverage. These sites sent digitized radar target data directly to a direction center. Maintenance teams were dispatched from West Mesa AFS for regularly scheduled maintenance or when fault indicators suggested the site had problems. The West Mesa AFS gap-filler radar was located at Zuni, NM.

West Mesa AFS became a BUIC I GCI site in 1962. West Mesa AFS and the 687th AC&W Radar Squadron were deactivated on 8 Sep 1968 and the site was transferred to the FAA. Now known as West Mesa FAA Radar Site. The FAA site was update to the Common Air Route Surveillance Radar (CARSR) circa 2015.

Physical Plant

The physical plant of the site was divided into the main site, a cantonment area, a housing area and a radio site. The main site housed the operations buildings, the radar towers, and the backup generators. The cantonment area housed the enlisted barracks, the bachelor officer's quarters, the orderly room, the dining hall, the motor pool and other support buildings. Apart from the main site was a small 27 unit housing area for critical married personnel built in 1959. A separate Ground to Air Transmitter/Receiver (GATR) radio site housed the radio equipment for directing aircraft intercepts.
