The 10th Space Warning Squadron at Cavalier Air Force Station, N.D., is located 20 miles south of the Canadian and U.S. border. The squadron is a geographically separated unit of the 21st Space Wing, Peterson Air Force Base, Colo.

Provide flawless missile warning and space surveillance to ensure space superiority and to defend our nation and allies.
The squadron operates and maintains the world's most capable phased-array radar system. The Perimeter Acquisition Radar Attack Characterization System (PARCS) continuously provides critical missile warning and space surveillance data to North American Aerospace Defense Command (NORAD), United States Strategic Command (USSTRATCOM), and regional combatant commanders. PARCS monitors and tracks more than half of all earth-orbiting objects to enable space situational awareness and space control. Additionally, 10 SWS provides attack characterization data to the Secretary of Defense and the President for real-time war plan execution decisions.

The PARCS radar is easily the most prominent building on Cavalier AFS. It is a concrete structure that stands 125 feet high. Additional facilities at 10 SWS include the industrial building which houses the unit motor pool and supply areas, fire station, and gymnasium in separate buildings. There is also an eight-unit bachelor crew quarters and 15-unit security forces alert facility. The squadron also has an on-site family housing complex of 14 three- or four-bedroom units with fenced yards and landscaping. The Community Activity Center houses a heritage hall, hobby and activities area, shoppette, lounge area, library, theater, cafeteria and bowling lanes.

A mixture of military and civil service people are assigned to 10 SWS. Most of the military members are assigned to the operations directorate, which is responsible for the Missile Warning Operations Center where missile warning and space surveillance missions are performed. The remainder of the assigned military and civilian workers provide support functions and quality assurance evaluation functions for various contracted activities on Cavalier AFS. There are also contract workers at the unit who provide such services as fire protection, law enforcement, custodial care, operations, maintenance and supply. Security forces personnel from Grand Forks AFB provide both internal and external security for the radar.

The unit was originally the acquisition radar portion of the United States' only operational antiballistic missile system, known as SAFEGUARD. Due to the 1972 Anti-Ballistic Missile Treaty, components of the SAFEGUARD complex, with the exception of PARCS at Cavalier Air Force Station, were deactivated in February 1976.

In January 1977, under the US Army, PARCS began passing tactical warning and attack assessment data. In October of 1977, the NORAD Early Warning Mission was transferred to the Air Force and two months later the spacetrack capability was added. In December 1979 the unit was transferred from Aerospace Defense Command to Strategic Air Command.

The unit, as it exists today, joined Air Force Space Command in 1983 as Detachment 5, 1st Space Wing. On Aug. 1, 1986, the unit was redesignated as the 10th Missile Warning Squadron, 1st Space Wing. It was renamed the 10th Space Warning Squadron on May 15, 1992, when the 1st Space Wing and 3rd Space Support Wing were inactivated and the 21st Space Wing was activated. In September of 2007, the installation, along with PARCS, was transferred to the Air Force.

Since its construction, PARCS and the military members and civilians who operate and maintain it, have constantly watched the skies for any signs of threat and allowed the tracking of satellites and other man-made objects.
