Sweetwater Air Force Station

Sweetwater Air Force Station (1956-1969) - A Cold War Air Force Radar Station first established in 1956 near Sweetwater, Nolan County, Texas. Named Sweetwater Air Force Station after the location. Initially assigned a Permanent ID of M-89, later a Sage ID of Z-89. Abandoned as an Air Force Station in 1969. History of Sweetwater Air Force Station Established in 1956 and became operational in 1956 as Sweetwater Air Force Station manned by the 683rd AC&W Squadron. The station initially had both a Ground-Control Intercept (GCI) and early warning misssion. The early warnng mission involved tracking and identifing 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. Initial equipment included the MPS-11 search radar and a TPS-10D height finder radar. The TPS-10D was replaced by an FPS-6A Height Finder in 1961 and it was later upgraded to an FPS-90. The MPS-11 was replaced by an FPS-67B in the mid 1960s. Sweetwater AFS and the 683rd were deactivated in 1969. Sweetwater AFS was responsible for the maintenance of two remote unattended gap filler radar sites. The 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 Sweetwater AFS for regularly scheduled maintenance or when fault indicators suggested the site had problems. The Sweetwater AFS gap filler radars were located at Big Spring and Sidney, Texas. From 1960 to 1966 the Army Air Defense Command Post (AADCP) controlling the Dyess Nike-Hercules anti-aircraft missile sites (DY-10 and DY-50) was co-located with the Sweetwater AFS operations. The AADCP used the CSG-5 Battery Integration and Radar Display Equipment (BIRDIE) with inputs from the USAF radars. The physical plant of the site was divided into a 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 24 unit housing area for critical married personnel. A separate Ground to Air Transmitter/Receiver (GATR) radio site housed the radio equipment for directing aircraft intercepts.
