Originally, PARCS was the Perimeter Acquisition Radar (PAR) site for the cancelled ‘Safeguard’ ABM System, Grand Forks AFB defense area (1975-76), a Cold War endeavor involving anti-ballistic missiles.
Since 1977, it has been an active Air Force missile-warning radar station. The 125-feet PARCS radar building is designed to provide missile warning and space surveillance for the North American Aerospace Defense Command, USSTRATCOM and regional combatant commanders. After the signing of the Anti-Ballistic Missile treaty between the United States and Former Soviet Union, the Safeguard project was cancelled and the Air Force was given control of the PAR installation.
Originally, PARCS was named the Concrete Early Warning Station, after the town of Concrete, ND. Since 1983, it has been part of Air Force Space Command and moved that same year to Cavalier after the post office in Concrete closed.
