Space Systems Command

Space Systems Command (SSC) is the United States Space Force's space development, acquisition, launch, and logistics field command. It is headquartered at Los Angeles Air Force Base, California, and manages the United States' space launch ranges.

Air Research and Development Command was redesignated as Air Force Systems Command in 1961. As part of that reorganization, the Space Systems Division (SSD) was established on 20 Mar 1961 and organized (activated) on 1 Apr 1961. In 1967, the Space Systems Division was reorganized as the Space and Missile Systems Organization (SAMSO), absorbing the Ballistic Systems Division's mission. In 1979, the Space and Missile Systems Organization was renamed the Space Division and divested itself of ballistic missile development. In 1989, the Space Division returned to its historic name of the Space Systems Division and regained its ballistic missile development role in 1990.

With the merger of Air Force Systems Command and Air Force Logistics Command in 1992, the Space Systems Division was redesignated the Space and Missile Systems Center (SMC). In 2001 the SMC was reassigned to Air Force Space Command, remaining attached through its redesignation as Space Operations Command in October 2020. On 22 April 2021, it changed status from a U.S. Air Force unit to a U.S. Space Force unit and was reassigned from Space Operations Command to Headquarters United States Space Force. On 13 August 2021, the Space and Missile Systems Center was upgraded into a Space Force field command, named Space Systems Command.
