The Perimeter Acquisition Radar and Attack Characterization System (PARCS)is a concrete structure 121ft high which 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 over half of all earth-orbiting objects to enable space situation awareness and space control. The PARCS radar is currently manned by the 10th Space Warning Squadron of the 21st Space Wing at Cavalier Air Force Station, North Dakota.
