Fort Yukon Long Range Radar Site is a radar site of the United States Air Force. It is located east-southeast of Fort Yukon, Alaska. It was the former Fort Yukon Air Force Station (AAC ID: F-14, LRR ID: A-01), a General Surveillance Radar station. The ground control intercept (GCI) station was closed on 1 November 1983, and was redesignated as a Long Range Radar (LRR) site as part of the Alaska Radar System. Today, it remains active as part of the Alaska NORAD Region under the jurisdiction of the 611th Air and Space Operations Center, Elmendorf AFB, Alaska. History Fort Yukon AFS was a continental defence radar station constructed to provide the United States Air Force early warning of an attack by the Soviet Union on Alaska. The station was opened in 1958 as a Ground-Control Intercept (GCI) and warning station, operated by the 709th Aircraft Control and Warning Squadron (AC&W Sq). The squadron operated AN/FPS-3, AN/FPS-20, and AN/FPS-6 radars. As a GCI station, the squadron's initial role was to guide interceptor aircraft based at Ladd AFB near Fairbanks toward unidentified intruders picked up on the unit's radar scopes. Later, the station was redesignated as a radar surveillance station, with the squadron providing information 24/7 the Direction Center at Murphy Dome AFS where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile. The station was known to be the coldest radar station in Alaska, with temperatures sinking as low as -70 degrees Fahrenheit during the winter. Due to the extreme temperatures, most of the site's operations were housed indoors, in a large composite structure consisting of a power/heating plant, water and fuel storage tanks, gymnasium and other support office buildings. Two other buildings contained living quarters, work areas, and recreational facilities plus opportunities for such sports as skiing, skating, horseshoes, and basketball. The buildings were connected by enclosed portals so no one needed to go outside in winter unless absolutely necessary. Tours at the station were limited to one year because of the psychological strain and physical hardships. Mail was usually delivered twice a week. The inaccessibility made the personnel at the site responsible for maintenance if anything went wrong. Water mains occasionally froze and ruptured. Communications were initially provided by a high frequency radio system which proved unreliable because of atmospheric disturbances. The Alaskan Air Command, after investigating various options,
