Cut Bank Air Force Station (Perm ID: P-24, SAGE ID: Z-24) is a closed United States Air Force General Surveillance Radar station. It is located 30.4 miles (48.9 km) northwest of Cut Bank, Montana. It was closed in 1965.
History
The facility was hosted by the 681st Aircraft Control and Warning (AC&W) Squadron, Air Defense Command between April 1952 and June 1965. Cut Bank AFS replaced an earlier radar site at Del Bonita, Montana (LP-24) which had opened in March 1951.
The 681st AC&W Squadron started operating AN/FPS-3 and AN/FPS-4 radars in April 1952, and initially the station functioned as a Ground-Control Intercept (GCI) 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. In 1958 an AN/FPS-20 search radar replaced the AN/FPS-3 at this site. In the following year two AN/FPS-6B height-finder radars superseded the AN/FPS-4.
In 1961 this site was integrated into the SAGE system, the squadron being re-designated as the 681st Radar Squadron (SAGE). 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. In 1962 the AN/FPS-20A was further upgraded and redesignated as an AN/FPS-66. In 1963 one AN/FPS-6B was removed and on 31 July, the site was redesignated as NORAD ID Z-24. In 1964 the other AN/FPS-6B was upgraded to an AN/FPS-90, and an AN/FPS-26A height-finder radar was installed.
In addition to the main facility, Cut Bank operated an AN/FPS-14 Gap Filler site:
- Browning, MT (P-24A) 48°52′14″N 113°10′22″W / 48.87056°N 113.17278°W
- Sweetgrass, MT (P-24C) 48°58′49″N 111°57′43″W / 48.98028°N 111.96194°W
The station was closed on 1 March 1965 as part of a general reduction of ADC. Today it is largely intact, and abandoned.
