On July 1, 1957, The United States Air Force Air Defense Command established a Phase III Mobile Radar station at NAS Jacksonville with the 679th Aircraft Warning and Control Squadron operating AN/FPS-3, AN/FPS-8, and AN/MPS-14 radars as part of the integrated ADC radar network. It was designated as ADC site M-114. In 1962 AN/FPS-66 radar and a pair of AN/FPS-6 heightfinder radars were added. During 1962 M-114 joined the Semi Automatic Ground Environment (SAGE) system, and the squadron was re-designated as the 679th Radar Squadron (SAGE) on 1 October 1962. On 31 July 1963, the site was redesignated as NORAD ID Z-114. In addition to the site at NAS Jacksonville, the 679th operated several "Gap Filler" remote sites to extend its radar coverage at Bunnell, FL and Blythe Island, GA. In 1963 M-114 became a joint-use facility with the Federal Aviation Administration (FAA). It performed routine general radar surveillance until 30 September 1981 when the site was inactivated.A Handbook of Aerospace Defense Organization 1946–1980, by Lloyd H. Cornett and Mildred W.
