Indian Mountain Air Force Station (AAC ID: F-16, LRR ID: A-03) is a closed United States Air Force General Surveillance Radar station. It is located east-southeast of Hughes, Alaska. The radar surveillance station was closed on 1 November 1983, and was re-designated 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. It is one of fifteen Long Range Radar Sites within Alaska maintained and operated by ARCTEC, a subsidiary of Arctic Slope Regional Corporation. History Indian Mountain 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. It was one of the 10 original AC&W surveillance stations constructed as part of the establishment of a permanent air defense system in Alaska during the early 1950s. Construction of the station, began in September 1950 and was completed in November 1953. The Army Corps of Engineers undertook the project. The location of the station made construction a challenge. Military engineer construction personnel built a 9.1 mile road to the top of the mountain where the radars were located (upper camp) and a base station and airstrip (lower camp). The lower camp , located at the confluence of the Indian River and Utopia Creek, included a runway opened in May 1952 with a 12-percent slope, the steepest remote site runway. The upper camp, at the summit of Indian Mountain (elevation 4,234 feet), could be reached by the road. The station consisted 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 station buildings were, except for the civil engineering building connected by heated hallways. As a result, personnel stationed there, with only very few exceptions, were able to wear "summer" uniforms year round, unless they had a need to go outside during the winter season. The coverings of the station's three radar towers were heated from within to keep the covering from becoming brittle from extreme cold, and thus subject to being damaged or destroyed by high winds. Tours at the station were limited to one year because of
