 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.
