The United States Air Force's 5th Expeditionary Space Operations Squadron is an expeditionary satellite operations unit under the Air Force Space Command.


The 5th Expeditionary Space Operations Squadron (ESOPS) was formed by the Air Force Satellite Control Facility. The squadron was provisionally activated as Operating Location-A, 750th Space Group, on October 1, 1992. This satellite control facility established one of the Air Force's satellite operations locations. AFSCF was later divided into the 2nd Space Test Group and the Consolidated Space Test Center (CSTC)[3] on October 1, 1987, when AFSPC took over Onizuka Air Force Base, now Onizuka Air Station. OL-A encompassed the CSTC divisions of VOS, VOE, and VOD.[jargon] The 5 ESOPS was officially activated 22 November 1993, under the 50th Operations Group and within one year, the 21st Space Operations Squadron (SOS) absorbed the roles of the 2nd Satellite Tracking Group Operations Division and the 1999th Communications Squadron Operations Division. After 1995 Base Realignment and Closure Committee directed the realignment of Onizuka AFS, the 21st SOS absorbed the roles of the 750th Space Group and all subordinate units and the 5th Space Operations Squadron.

Three weeks later, in late 1993, the squadron launched a DSCS III and a NATO IV communication satellite. It also supported NASA's Hubble telescope repair. The squadron has launched the IUS in support of NASA programs including all seven TDRS and three inter-planetary spacecraft: Galileo (Jupiter), Magellan (Venus), and Ulysses (Sun).
