Northeast Cape Air Force Station (AAC ID: F-09) is a closed United States Air Force General Surveillance Radar station. It was a forward outpost, located on St. Lawrence Island in the Bering Sea, between Alaska and Siberia, southwest of Nome, Alaska. ==History== Northeast Cape 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 area surrounding the Northeast Cape base site had been a traditional camp site for several Yupik families for centuries. During World War II, many joined the Alaska Territorial Guard (ATG) for defense of the island. Following disbandment of the ATG in 1947 and commencing with construction of the site in 1952, many islanders joined the Alaska National Guard to continue to provide land-based defense. The station was the closest forward radar surveillance station to mainland Soviet Union, its location being about 140 miles east-southeast of the Siberian coastline. The station, as with others of its type, was divided into two areas. The Cantonment, or base station area was located at the base of tall hills along the northeast coast of the Island. A port facility was constructed to facilitate the landing of construction equipment and bulk materiel, along with a gravel airstrip for shipment of personnel and essential supplies. The station consisted of 25 buildings and miscellaneous support structures . 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 the psychological strain and physical hardships. The 712th Aircraft Control and Warning Squadron, operated AN/FPS-3, and AN/FPS-20A radars. As a surveillance station, its mission was to monitor the airspace for aircraft activity and provide information 24/7 to the air defense Direction Center at Murphy Dome AFS near Fairbanks, where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile. 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, decided to build the White Alice Communications System, a system of Air Force-owned tropospheric scatter and microwave radio relay sites operated by the Air Force Communications Service (AFCS). The Northeast Cape site was activated in 1957. After the station's inactivation by the Air Force in 1969, the White Alice communications site remained active supporting United States Navy operations in the Bering Sea. It was turned over to the Navy in 1972, eventually being inactivated in 1975. A United States Air Force Security Service detachment of the 6981st Radio Group Mobile (RGM), Elmendorf Air Force Base, was co-located on the site. The detachment's Morse code intercept operators and Russian language linguists were tasked with the surveillance and collection of voice and electronic signals, to be forwarded to the National Security Agency for intelligence analysis. A direction finding receiver was also manned, both for surveillance and search and rescue. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Northeast Cape Air Force Station」の詳細全文を読む スポンサード リンク
