North Charleston Air Force Station North Charleston Air Force Station ( ADC ID : M - 113 NORAD ID : Z - 113 ) is a closed United States Air Force General Surveillance Radar station . It is located in the City of North Charleston , South Carolina . It was closed in 1980 . History . North Charleston AFS was established in 1954 by Air Defense Command as one of a planned deployment of forty - four Mobile radar stations to support the permanent ADC Radar network in the United States sited around the perimeter of the country . This deployment was projected to be operational by mid - 1952 . Funding , constant site changes , construction , and equipment delivery delayed deployment . This site became operational on 1 June 1955 when the 792d Aircraft Control and Warning Squadron activated an AN / MPS - 7 radar at the site , designated M - 113 . Logistical support for the radar site was provided by the adjacent MATS Charleston AFB , and initially the station functioned as a Ground - Control Intercept ( GCI ) and warning station . As a GCI station , the squadron ' s role was to guide interceptor aircraft toward unidentified intruders picked up on the unit ' s radar scopes . By 1956 operational radars included the AN / MPS - 7 , AN / GPS - 3 , AN / MPS - 14 , and AN / MPS - 8 sets . In late 1959 this site was also performing air traffic control duties for the FAA with a newly installed AN / FPS - 20 A search radar and AN / MPS - 14 set . In 1961 the search radar was upgraded and redesignated as an AN / FPS - 66 and an AN / FPS - 26 height - finder radar was installed . During 1962 North Charleston AFS joined the Semi Automatic Ground Environment ( SAGE ) system , initially feeding data to DC - 04 at Fort Lee AFS , Virginia . After joining , the squadron was redesignated as the 792d Radar Squadron ( SAGE ) on 25 March 1962 . The radar squadron provided information 24 / 7 the SAGE Direction Center where it was analyzed to determine range , direction altitude speed and whether or not aircraft were friendly or hostile . On 31 July 1963 , the site was redesignated as NORAD ID Z - 113 . By 1966 the site was operating an AN / FPS - 27 . In addition to the main facility , Fort Fisher AFS operated several unmanned Gap Filler sites : The sites at Statesburg and Georgetown were opened in 1959 AN / FPS - 14 radars , Parris Island was taken over from the closed site ( M - 112 ) at Hunter AFB , Georgia in December 1961 and was an AN / FPS - 18 . All the Gap Fillers were closed in June 1970 . Over the years , the equipment at the station was upgraded or modified to improve the efficiency and accuracy of the information gathered by the radars . The facility came under Tactical Air Command jurisdiction in 1979 with the inactivation of Aerospace Defense Command and the activation of ADTAC . North Charleston AFS was closed on 4 June 1980 . In 1980 the Air Force built a height - finder tower at Jedburg , SC , an FAA site located twenty - two miles northwest of Charleston and closed North Charleston AFB . The North Charleston GATR ( Ground Air Transmitter Receiver ) site ( R - 113 ) , operated by the 1968th Communications Squadron remained open temporarily after the parent radar sited closed . Today North Charleston Air Force Station has been mostly torn down . Some former AF buildings are now used as government offices for the city of North Charleston . The large support buildings for the FPS - 27 , FPS - 26 and FPS - 66 radars remain . The former housing units used for low - income housing . Also the site hosts a local Marine Corps Reserve Training Center . The Gap Filler at Parris Island is now part of a golf course ; the one at Georgetown Airport has been redeveloped ; the Stateburg site remains , with an existing radome .
