The Space and Missile Systems Center (SMC) is the United States Space Force acquisitions and development center and is headquartered at Los Angeles Air Force Base (LAAFB), California. It was first established as the Western Development Division on 1 April 1954 and is the oldest space organization in the U.S. Armed Forces. Initially, it had responsibility for ballistic missiles, gaining space responsibilities in 1955. In 1957, it was redesignated as the Air Force Ballistic Missile Division. With the standup of Air Force Systems Command in 1961, the Air Force Ballistic Missile Division was split, forming the Space Systems Division and Ballistic Systems Division. In 1967, they were remerged as the Space and Missiles Systems Organization, before being split again in 1979 into the Space Division and Ballistic Missile Office. In 1990, both organizations regained their former names of the Space Systems Division and Ballistic Systems Division, however the Ballistic Systems Division was renamed the Ballistic Missile Office and subordinated to the Space Systems Division. In 1992, Air Force Systems Command was inactivated and replaced with Air Force Materiel Command, and the Space Systems Division was renamed the Space and Missile Systems Center. In 2001, it was transferred from Air Force Materiel Command to Air Force Space Command, becoming part of the U.S. Space Force at its formation in 2019.
