10th Space Warning Squadron
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. Mission. 10 SWS provides tactical warning and attack assessment of sea-launched and intercontinental ballistic missiles launched against the continental United States and southern Canada. Additionally, 10 SWS provides surveillance, tracking and space object identification for the United States Space Command Space Surveillance Network (SSN). History. The unit was originally the acquisition radar portion of the United States' only operational anti-ballistic missile system, known as SAFEGUARD. 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. 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 10 July 1986, the unit was redesignated as the 10th Missile Warning  Squadron, and was activated on 1 August 1986. It was renamed the 10th Space Warning Squadron on May 15, 1992, when the 1st Space Wing and 3d Space Support Wing were inactivated and the 21st Space Wing was activated.
