History
Red Bluff Air Force Station was initially part of Phase II of the Air Defense Command Mobile Radar program. The Air Force approved this expansion of the Mobile Radar program on October 23, 1952. Radars in this network were designated “SM.” The station consisted of 30.84 acres, was acquired by the Air Force on May 25, 1955.The station became operational on 1 April 1956 when the 859th Aircraft Control and Warning Squadron was moved to the new station. Initially Red Bluff used AN/MPS-8 and AN/MPS-11 radars, and initially the station functioned as a Ground-Control Intercept and warning station. As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes. The AN/MPS-11 remained until 1963. In 1959 the Air Force placed AN/FPS-6 and -6A height-finder radars and removed the AN/MPS-8 from Red Bluff.
During 1960 Red Bluff AFS joined the Semi Automatic Ground Environment system, feeding data to DC-13 at Adair AFS, Oregon. After joining, the squadron was redesignated as the 859th Radar Squadron on 15 July 1960. The radar squadron provided information 24/7 the SAGE Direction Center where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile. On 31 July 1963, the site was redesignated as NORAD ID Z-157.
In 1964 Red Bluff became a joint-use facility with the Federal Aviation Administration, using the AN/FPS-67 search and AN/FPS-6 and AN/FPS-90 height-finder radars located on site.
In addition to the main facility, Red Bluff operated several AN/FPS-14 Gap Filler sites:
- Janesville, CA
- Whitmore, CA
- Hayfork, CA
The majority of the site is known as Ridgeway County Park, with the remainder used by the FAA as a weather station. Many of the original structures have been removed. Structures present and still in use at the time of a 1991 USACE site investigation include the operations building, rec hall, pump house and well, and sewage treatment facility. Structures still present but not used since DOD occupation include a swamp cooler for the rec hall, the sewage treatment plant chlorinator, and the sewage treatment pump house.
