Barrington Air Station (1958-1990) - A Cold War U.S. Air Force Radar Station established at Baccaro Point, Nova Scotia, Canada. Initially assigned a Permanent ID of M-102, a Sage ID of C-102 and a JSS ID of R-01. Transferred to the Canadian RCAF in 1962 and operated by them as RCAF Station Barrington and in 1967 as CFS Barrington reflecting the integration of the Canadian Forces. The site continued operation until deactivated in 1990 and was then transitioned into operation as Canadian Coastal Radar Site Barrington.

Barrington Radar Station Evolution.


Construction of the radar site at Baccaro Point started in 1955 and was completed in 1957. The site became operational on 1 Aug 1958 as Barrington Air Station manned by the 672nd Aircraft Control & Warning (AC&W) Squadron.

Initial equipment included the FPS-3A search radar and FPS-6B height-finder radars. In 1961, the FPS-3A search radar was replaced by a FPS-27 Search and a FPS-26A height-finder was added.

SAGE System Transition

The transition of the manual GCI system to the automated SAGE system began with the installation of the FST-2 coordinate data transmitter and search radar upgrades. The FST-2 equipment digitized the radar returns and transmitted the digital returns to the SAGE direction center. Under the SAGE System, interceptor aircraft were directed to their targets by the direction center computers and controllers, greatly reducing the need for local controllers and equipment at every radar station.

The FST-2 was a very large digital system using vacuum tube technology. Over 6900 vacuum tubes were used in each FST-2 requiring 21 air-conditioned cabinets, 40 tons of air conditioning, 43.5 kva of prime power and usually a large new addition to the operations building. The FST-2B modification added two more cabinets but with newer solid state (transistor) technology to process coded responses from aircraft transponders.

In the midst of the SAGE System transition, the radar site was turned over to the RCAF on 1 Jun 1962, renamed RCAF Station Barrington and operated by 23 AC&W Squadron. The 23 AC&W reported to the Bangor Sector of the 26th NORAD Division and also fed data to the NNR. Initial operation was as a manual input site to the SAGE System Direction Center.

1969-10-14 - 1983-06-15 Hancock SAGE Direction Center DC-03 21st NORAD Region (Auto)

The site began operation as a SAGE site on 1 Jun 1964 initially feeding the Topsham SAGE Direction Center DC-05. On 29 Aug 1967, The 213 Radar Squadron was renamed at the same time as the integration of the Canadian Forces. The unit was now Canadian Forces Station Barrington reporting to the 35th Air Division at Hancock Field, Syracuse, New York. On 14 Oct 1969, they began reporting to the 21st NORAD Region which was also located at Hancock Field.

About 1972 the FST-2B would have been replaced by the much smaller and more reliable FYQ-47 as a part of the FST-2/FYQ-47 replacement program. The FYQ-47 and it's associated GPA-124 (Coder-decoder group) were in place at Barrington by November 1971.

As the SAGE System closed down in 1983, CFS Barrington began reporting to the Canada East ROCC at North Bay on 15 Jun 1983. The designation of the site was changed from C-102 to R-01 to reflect it's new role in the JSS System. CFS Barrington continued operation until it was deactivated in 1990.


CFS Barrington discontinued operation on 1 Aug 1990. A small detachment of personnel remained to prepare the location for the new Canadian Coastal Radar Site Barrington.

Physical Plant

The physical plant of the site was divided into the main site, a cantonment area, and a radio site. The main site housed the operations buildings, the radar towers, and the backup generators. The cantonment area housed the enlisted barracks, the bachelor officer's quarters, the orderly room, the dining hall, the motor pool and other support buildings. Originally no family housing was available and accompanied personnel had to find housing on the local economy. In 1971, a mobile home site, with 35 units, was constructed on Sherose Island, located some 15 miles west of the station near Barrington Passage.

A separate radio site housed the radio equipment for directing aircraft intercepts. Like most early radar stations, Barrington originally had a radio transmitter site and a separate radio receiver site used by local controllers for voice direction of fighter interceptors to their targets. With the SAGE System, the SAGE Direction centers had the primary task of directing intercepts and the local radio sites were reconfigured, usually into a single site that was known as the Ground to Air Transmitter Receiver (GATR) site. The GATR site communicated with the interceptors from either the local site or the SAGE direction center via voice commands and/or a digital data link.
