Closed United States Air Force General Surveillance Radar station
Minot Air Force Station (ADC ID: P-28 NORAD ID: Z-28) [Permanent Installation Number (PIN): 1445; Installation Location Code (ILC): QJVM]) is a closed United States Air Force General Surveillance Radar station. It is located 16.2 miles (26.1 km) south of Minot, North Dakota; on the west side of US Highway 83. It was closed in 1979. A portion of the property was reopened in 1984 as the Minot Communications Site and served until 1997.
Minot Air Force Station was the first major Air Force installation in North Dakota, even predating the two "large" bases, Minot Air Force Base and Grand Forks Air Force Base.
History
Minot Air Force Station was part of the last batch of twenty-three radar stations constructed as part of the Air Defense Command permanent network. It was activated on 20 May 1951 at Max, ND, and declared completely operational in 1952.
The 786th Aircraft Control and Warning Squadron began operations with AN/FPS-3 and AN/FPS-5 radars in April 1952, 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.
It was named Minot Air Force Station on 1 December 1953. During 1957 an AN/GPS-3 search radar saw brief use. In 1958 the original radars were replaced by AN/FPS-20 search and AN/FPS-6 height-finder sets. A second height-finder set, AN/FPS-6B, was installed during the following year.
During 1961 Minot AFS joined the Semi Automatic Ground Environment (SAGE) system, initially feeding data to DC-20 at Malmstrom AFB, Montana. After joining, the squadron was redesignated as the 786th Radar Squadron (SAGE) on 15 July 1961. 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.
By the end of 1961 the search set had been upgraded and redesignated as an AN/FPS-66. On 31 July 1963, the site was redesignated as NORAD ID Z-28.
An AN/FPS-26A height-finder radar was installed in 1964, and the AN/FPS-6 was retired. The AN/FPS-6B was upgraded to an AN/FPS-90 also that year. In 1964 the site received an AN/FPS-27 search radar which became fully operational in early 1965. The AN/FPS-66 was removed later in 1965. In 1968 the AN/FPS-90 was retired.
In addition to the main facility, Minot operated three unmanned AN/FPS-14 (P-28A) and AN/FPS-18 (P-28B/C) Gap Filler sites:
The Alexander site was reassigned to Minot after Dickinson AFS (Z-177) closed in 1965. The site is now home to the Watford City Joint Surveillance System (JSS) (ARSR-4) LRR site (Z-300/J-76).
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. In early 1979 the Air Force announced that the station would be closing due to what was called "redundancies with more strategically located radars".[This quote needs a citation] On 29 September 1979 the 786th Radar Squadron was inactivated and the station was closed.
In 1984, a portion of the station was reopened by the USAF as the Minot Communication Site. It was closed again in 1997 and struck from the USAF property register and liquidated c.. 1998. Minot AFS has been sold to civilian interests, and has been reused as a housing subdivision colloquially known as the Radar Base.
Buildings and facilities
Buildings on the station include:[1]
- Gate
- The controlled entry point to the station
- Recreation hall
- Transmitter building
- Used for radio contact with airborne aircraft and other ground stations
- Search radar tower
- Height finder radar tower
- (2) Radomes
- The radome "balloons", made up of several layers of latex rubber-coated nylon, are held up by one-tenth pound of air pressure per square inch. In the event of wind (a common occurrence in North Dakota), the pressure within the "balloon" is automatically adjusted by blowers.
- Heating plant
- Steam heat is provided for the entire station by two coal-fired boilers. There is a 70,000-gallon water reservoir fed by two 540-foot-deep (160 m) wells. The heating plant used approximately 1,000 tons of coal annually.
- Hose houses
- Hose houses are insulated huts for fire hydrants. Six are located at strategic locations around the station.
- Air Installations Building
- This is the building that most of the 17 civilian contractors work out of.

- Water distribution plant
- Water purification plant
- 20,000 gallons of high-alkaline water get processed into potable water daily by using 94%-concentrate sulfuric acid plus other filtering and purifying chemicals.
- Living quarters
- (2) Barracks
- (25) Houses
- Motor Pool
- The pumps are fed by a 4,000-gallon underground gasoline storage tank, and the station uses in excess of 1,000 gallons monthly. Only minor repairs and preventative maintenance are performed here, the rest being contracted to local businesses.
- Operations Building
- The "Mission Central" of the base where most of the operations of the base are performed.
- Chapel
- Dining hall
- Dispensary
- Although mostly a first aid station, there is a fully qualified medic on duty here 24 hours a day.
