Kalispell Air Force Station

Kalispell Air Force Station (1961-1978) - A Cold War U.S. Air Force Radar Station first established in 1961 near present day Lakeside, Flathead County , Montana. Named Kalispell Air Force Station after the town of Kalispell. Initially assigned a Permanent ID of TM-179 and later a Sage ID of Z-179. The site became an FAA operated JSS site in 1978 with a JSS ID of J-78 and became known as Lakeside FAA Radar Site.

Initial equipment included the FPS-7 search radar, two FPS-90 height finder radar sets and the FST-2 coordinate data transmitter. The FST-2 equipment digitized the radar returns and transmitted the digital returns to the SAGE direction center. The FST-2 was a very large digital system using vacuum tube technology. Over 6900 vacuum tubes were used in each FST-2 requiring 21 air conditioned cabinets, 40 tons of airconditioning, 43.5 kva of prime power and an usually a large addition to the operations building. The FST-2B modification added two more cabinets but with newer solid state (transistor) technology to process coded responses from aircraft transponders.

With the closure of DC-20 in 1969 Kalispell was connected to the McChord SAGE Direction Center DC-12 || at McChord AFB in Washington State where it remained until it was closed. Closure Kalispell AFS and the 716th Radar Squadron were deactivated on 1 Apr 1978 and the facilities turned over to the FAA. The radar site then became joint use JSS site J-78 feeding radar data to FAA and USAF sites. A small team of USAF technicians remained as an operating location to maintain certain pieces of equipment. Now known as Lakeside FAA Radar Site. Gap Fillers Kalispell AFS Gap Filler Radar Sites (edit list) ADC NORAD Location State Type From To GPS Notes TM-179B Z-179B Yaak AFS Montana FPS-14, FST-1 1958 1960 48.861667, -115.7225 TM-179C Z-179C Eureka Montana 48.864722, -115.125556 Initially Kalispell AFS was not slated to support any remote gap filler radar sites. Gap filler sites were usually placed in locations where the main search radar lacked coverage. With the closure of Yaak Air Force Station in 1960 responsibility for the maintenance of their gap filler radar site at Eureka, Montana shifted to Kalispell AFS. The Yaak AFS site itself became an unattended gap filler site also the responsibility of Kalispell AFS. These sites sent digitized radar target data directly to a direction center. Maintenance teams were dispatched from Kalispell AFS for regularly scheduled maintenance or when fault indicators suggested the site had problems. Physical Plant Former Kalispell AFS Family Housing Units The physical plant of Kalispell AFS was divided into an upper operations site on Blacktail Mountain and a lower cantonment area in the present day community of Lakeside. The cantonment area included the housing, administrative and support facilities for the troops and a 27 unit housing area. The upper site housed the operations buildings, radar equipment and towers. A 15 mile access road connected the two areas.
