CFS Armstrong
Canadian Forces Station Armstrong (ADC ID: C-15) is a former General Surveillance Radar station. It is located 1.1 miles (1.8 km) east of Armstrong, Thunder Bay District, Ontario. It was closed in 1974.
It was operated as part of the Pinetree Line network controlled by NORAD.
There was military activity in Armstrong during the Second World War. The community was the site of a detachment of the US Army's 671st Signal Aircraft Warning Company (Reporting), established to detect an enemy air attack on the locks at Soo Locks in Sault Ste. Marie, Michigan. The site was opened in 1942 and abandoned in 1943 as an attack seemed less likely. It is believed that the facility was situated in the same place as CFS Armstrong and no trace of it remains.
As a result of the Cold War and with the expansion of a North American continental air defence system, Armstrong was selected as a site for a United States Air Force (USAF) radar station, one of the many that would make up the Pinetree Line of Ground-Control Intercept (GCI) radar sites.
This second period began with construction starting in 1952 and completed in 1954. The site was originally known as Armstrong Air Station in the early 1950s and it was home to the USAF's Air Defense Command (ADC) 914th Aircraft Control and Warning Squadron. ADC designated the site "C-15". Initial radars installed were AN/FPS-3C, AN/FPS-502, AN/TPS-502, and an AN/FPS-6B set. The squadron initially reported to the 30th Air Division at Willow Run AFS, Michigan.
As a GCI base, the 914th's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes. These interceptors were based at the 29th Air Division at Great Falls (Malmstrom) AFB, Montana. The squadron was inactivated on 1 November 1962.
On 1 April 1963 Armstrong AS was connected to the Semi Automatic Ground Environment (SAGE) system, and the station became a long-range radar site. It would no longer guide interceptors but only look for enemy aircraft, feeding data to the Duluth Air Defense Sector SAGE DC-10 Data Center of the 30th NORAD Region at Duluth AFS, Minnesota
Later that month, the American station was handed over to the Royal Canadian Air Force and renamed the site as RCAF Station Armstrong. This was part of an arrangement with the United States that came as a result of the cancellation of the Avro Arrow. Canada would lease 66 F-101 Voodoo fighters and take over operation of 12 Pinetree radar bases. The new radar unit, 38 AC&W Squadron, continued in the early warning role. It would later be known as 38 Radar Squadron. It was also upgraded with the following radars:
