== History ==
Established on 1 Jan 1951 and became operational on 1 Jun 1952 at Charleston Air Force Station manned by the 765th AC&W Squadron. The station initially had both a Ground-Control Intercept (GCI) and an early warning mission. The early warning mission involved tracking and identifying all aircraft entering their airspace while the GCI mission involved guiding Air Force interceptors to any identified enemy aircraft. Controllers at the station vectored fighter aircraft at the correct course and speed to intercept enemy aircraft using voice commands via ground-to-air radio.

Initial equipment included the [[FPS-3]] search radar and an [[FPS-5]] height-finder radar. The FPS-5 was replaced in 1957 with an [[FPS-6]] and a second one was added in 1958. The FPS-3 was also upgraded to an [[FPS-20]] in 1958. This was the starting configuration for entry into the SAGE system, the FPS-20, and two FPS-6s.

The site began operation as a SAGE site in May 1959 initially feeding the [[Topsham SAGE Direction Center DC-05]]. The search radar was upgraded to an FPS-27 in 1963 and an FPS-26A height-finder radar was installed. In 1966 the FPS-26A was converted to an FSS-7 SLBM detection & warning radar operated by Det 6, 14th Missile Warning Squadron.

In 1969 the [[Topsham SAGE Direction Center DC-05]] closed and control of Charleston AFS switched to the [[Hancock SAGE Direction Center DC-03]] and the 21st Air Divison where it remained until the site closed.

== Gap Filler Radars ==
Charleston AFS was responsible for the maintenance of two remote unattended gap-filler radar sites. {{GapFillerCommon}} The Charleston AFS gap-filler radars were located at Topsfield, ME, and Sedgwick, ME.

== [[BUIC System]] ==
Charleston AFS became a BUIC I GCI site 1 Mar 1963 and went operational as a BUIC II site on 1 Mar 1966. It was selected as a BUIC III site and in December 1969 the 765th Radar Squadron (SAGE) became the 765th Air Defense Group (BUIC). The BUIC III system provided a backup for a SAGE direction center and provided the ability to display sector-wide radar data on consoles for local weapons controllers. The system duplicated the functionality of the vacuum tube direction center computers with more up-to-date computers and replaced the FST-2 with a more up-to-date coordinate data transmitter, the [[FYQ-47]]. The FST-2 at Charleston AFS was loaded on a flatbed truck, taken to Brunswick NAS, and scrapped. As the threat from a Soviet bomber fleet lessened the decision came to mothball the BUIC system in 1974. 

Charleston AFS and the 765th were deactivated 30 Sep 1980.

== Physical Plant ==
The physical plant of the site was divided into the main site, a cantonment area, a housing area, and a radio site. The main site housed the operations buildings, the radar towers, and the backup generators. The cantonment area housed the five enlisted barracks, the bachelor officer's quarters, the orderly room, the dining hall, the motor pool, and other support buildings. Apart from the main site was a small 37 unit housing area for married personnel. The first 9 housing units were built about 1957 and the additional 28 units were added in 1964.

A separate radio site housed the radio equipment for directing aircraft intercepts. {{GATRSite|AFS=Charleston}}

== Current Status ==
Now Mountain View Youth Development Center near Charleston, Penobscot County, Maine. The housing area has been completely removed. Most of the cantonment buildings remain, repurposed for the detention facility. Most of the main operations site buildings and towers remain, in a deteriorated condition and unoccupied. The site was visited on 26 May 2018 but a request for access to the upper site was denied. Not much can be seen from public roads.
