The United States Space Force's 10th Space Warning Squadron (10 SWS), is a missile warning unit located at Cavalier Space Force Station, North Dakota operating the AN/FPQ-16 Perimeter Acquisition Radar Attack Characterization System.

[2] 10 SWS provides tactical warning and attack assessment of sea-launched and intercontinental ballistic missiles launched against the continental United States and southern Canada.

Due to the 1972 Anti-Ballistic Missile Treaty (SALT II), components of the SAFEGUARD complex, with the exception of the PARCS radar at Cavalier Space Force Station, were deactivated in February 1976.

The forerunner of the present day 10th SWS began passing tactical warning and attack assessment data to the Cheyenne Mountain Complex, Colo., in January 1977.

On 10 July 1986, the unit was re-designated as the 10th Missile Warning Squadron, and was activated on 1 August 1986.
