Cape Newenham AFS was originally equipped with an AN/FPS-3 Search Radar which was later modified as the AN/FPS-93A Search Radar. The station provided information 24/7 to the air defense Direction Center at King Salmon AFS where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile. An AN/FYQ-9 Semiautomatic Data Processing and Display System was installed and became operational in July 1965, eliminating the need to pass track data manually. Cape Newenham AFS was resupplied annually since 1950 by sealift. Bulk cargo was delivered across the beach in landing craft, while fuel was pumped ashore to storage tanks. It was part of the annual Cool Barge remote resupply operations originally known as Mona Lisa. The name was changed to Cool Barge in 1967. A runway was built in 1952 , north-northeast to facilitate the transportation of personnel and critical cargo. The squadron was assigned to various headquarters, including AAC. On 15 October 1977, the squadron was reassigned from Headquarters, AAC to the 531st AC&W Gp upon the reactivation of the latter. The Group was redesignated the 11th Tactical Control Group on 1 July 1981. 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 Cape Newenham site was activated in December 1957. It was inactivated in March 1979, and replaced by an Alascom owned and operated satellite earth terminal as part of an Air Force plan to divest itself of the obsolete White Alice Communications System and transfer the responsibility to a commercial firm. Construction of a composite building was begun in late 1975. The $11.7 million facility was accepted by the Alaska District Corps of Engineers in October 1980. However, occupancy was delayed until July 1981 because of safety deficiencies and changes in design. On 1 October 1977, AAC, after a trial period, implemented a site support contract with RCA Services as part of an Air Force-wide effort to reduce remote tours. Eighty military positions were deleted. The remaining 14 were primarily in operations. Over the years, the equipment at the station was upgraded or modified to improve the efficiency and accuracy of the information gathered by
