5th Space Surveillance Squadron

Between 1989 and 2003 this hosted the US Air Force's 5th Space Surveillance Squadron (5 SPSS) which was subordinate to the 21st Operations Group (21 OG) and the 21st Space Wing (21 SW), both at Peterson AFB, Colorado. These organisations in turn are subordinate to the 14th Air Force (14 AF) at Vandenberg AFB, California which reports to HQ Air Force Space Command (AFSPC), also at Peterson AFB, CO.

The 5 SPSS (initially designated "Detachment 1, 73rd Space Surveillance Group", or "Det 1 SSURGP") was part of the USAF's Passive Space Surveillance Network which tracked the physical location of emitting satellites in orbit. This data along with that from other systems was used to adjust the orbits of various satellites and manned vessels (for instance the Space Shuttle and the International Space Station) to reduce the risk of on-orbit collisions.

However other USAF systems and capabilities ultimately superseded DSTS and it was removed in 2002 and the unit was de-activated shortly thereafter. The 21st Space Wing now has a detachment at RAF Fylingdales, North Yorkshire, UK, to coordinate cooperative missile warning and space surveillance with RAF counterparts.
