Vandenberg is the federal government’s West Coast space launch complex, complementing the East Coast launch complex at Cape Canaveral. Vandenberg covers 153 square miles along 35 miles of coastline, north of Point Conception. On its grounds are around a dozen active and historic launch complexes, where most of the large rockets used by the USA in tests, or to put payloads into space, have been launched, including Atlases, Titans, Thors, Deltas, Minutemen, Peacekeepers, Falcons, and Minotaurs. Vandenberg has been used to deploy geosynchronous communication and remote sensing satellites, as well as many classified military payloads. It is also the site of fully functional ICBM launch facilities, used for testing and training. Several space tracking and long-distance radar facilities exist on the hills around the base, looking out over the Pacific Test Range, which extends over thousands of miles of ocean with remote atoll tracking sites. More than 15,000 people work at Vandenberg, including at the Combined Space Operations Center, which monitors, coordinates, and controls all activity in space, to the extent that is possible.
