Vandenberg Space Force Base, previously Vandenberg Air Force Base, is a United States Space Force Base in Santa Barbara County, California. Established in 1941, Vandenberg Space Force Base is a space launch base, launching spacecraft from the Western Range, and also performs missile testing. The United States Space Force's Space Launch Delta 30 serves as the host delta for the base, equivalent to an Air Force air base wing. In addition to its military space launch mission, Vandenberg Space Force Base also hosts space launches for civil and commercial space entities, such as NASA and SpaceX.
The United States Air Force's Air Force Satellite Control Facility (AFSCF) was a space command and control unit located at Onizuka AFS, California. It has the distinction of being heavily involved in the world's first reconnaissance satellite program, CORONA. Due to geological hazards, and the terrorism threat from its proximity to a major transportation link, the facility's command and control functions were moved to Schriever AFB, Colorado.
The Western Range (WR) is the space launch range that supports the major launch head at Vandenberg Space Force Base. Managed by the Space Launch Delta 30, the WR extends from the West Coast of the United States to 90° East longitude in the Indian Ocean where it meets the Eastern Range Operations involve military, government, and commercial interests. The WR has been operated by civilian contractors since its establishment, following the precedent of the Eastern Range. On 1 October 2003, InDyne Inc. took over the range contract from ITT Industries which had operated the range for the previous 44 years.

While the United States Space Force gained its independence on 20 December 2019, the history of the United States Space Force can be traced back to the beginnings of the military space program following the conclusion of the Second World War in 1945. Early military space development was begun within the United States Army Air Forces by General Henry H. Arnold, who identified space as a crucial military arena decades before the first spaceflight. Gaining its independence from the Army on 18 September 1947, the United States Air Force began development of military space and ballistic missile programs, while also competing with the United States Army and United States Navy for the space mission.
Space Delta 1 is a United States Space Force unit responsible for space training. It runs the Space Force's basic military training, weapons school, and other advanced training courses and exercises. It was established on 23 August 2021 following the establishment of the Space Training and Readiness Command, the field command to which it reports. It is headquartered at Vandenberg Space Force Base, California.
Space Delta 12 is a United States Space Force unit responsible for space test and evaluation. It tests space systems and capabilities in support of weapon system acquisition, operational acceptance, and readiness. It was established on 23 August 2021 following the establishment of the Space Training and Readiness Command, the field command to which it reports. It is temporarily headquartered at Schriever Space Force Base, Colorado, but its final location requires a base selection process.
