Editing Tyndall Air Force Base (section)

====Radar station 1956–present====
On 1 July 1956 Tyndall AFB became the station operating for the third phase of the ADC mobile radar program, designated as '''TM-198'''. Activated by the 678th Aircraft Control and Warning Squadron, Tyndall became operational to support the [[CIM-10 Bomarc]] surface-to-air missile program at [[Hurlburt Field]]. In 1958 the site was operating with an [[AN/FPS-20]] search radar and a pair of [[AN/FPS-6]] height-finder sets to support the 4751st Air Defense Missile Squadron.

In 1962 the search radar was upgraded and re-designated as an [[AN/FPS-64]]. On 31 July 1963, the site was redesignated as NORAD ID Z-198. During 1965 Tyndall AFB joined the [[Semi Automatic Ground Environment]] (SAGE) system, feeding data to DC-09 at [[Gunter AFB]], Alabama. After joining, the squadron was re-designated as the [[678th Radar Squadron]] (SAGE) on 1 June 1965. Also in 1965, Tyndall became a joint-use facility with the [[Federal Aviation Administration]] (FAA).

It also received a [[Back-Up Interceptor Control]] (BUIC) II, and later BUIC III, capability to perform command and control functions. Tyndall retained this function until the 1980s. On 1 March 1970, the 678th
was redesignated as the [[678th Air Defense Group]].

In addition to the main facility, Tyndall operated two [[AN/FPS-14]] Gap Filler sites:
* Carrabelle, FL (TM-198A): {{Coord|29|51|57|N|084|37|53|W|name=TM-198A|display=inline}}
* Eglin AFB, FL (TM-198B): {{Coord|30|33|14|N|086|45|36|W|name=TM-198B|display=inline}}

On 1 October 1979, this site came under [[Tactical Air Command]] jurisdiction with the inactivation of Aerospace Defense Command and the formation of [[ADTAC]]. On 1 March 1983 the 678th Air Defense Group was inactivated and Tyndall became the home of the NORAD 23rd ADS (Air Defense Squadron) and operated the Southeast Regional Operations Control Center (SE ROCC), later renamed Sector Operations Control Center (SOCC).

The height-finder radar, modified as an [[AN/FPS-116]] c. 1977, was removed c. 1988. In 1995 an [[AN/FPS-64]]A was performing search duties. The site now{{when|date=August 2019}} operates an [[ARSR-4]] search radar under FAA control as part of the [[Joint Surveillance System]] (JSS) as site "J-11".<ref name="mul5"/><ref>''A Handbook of Aerospace Defense Organization 1946–1980'', by Lloyd H.
