Vandenberg Space Force Base, located at Point Arguello in Santa Barbara County, California, is home to the United States' Western Range and is considered the second most active rocket range and spaceport in the country (following Cape Canaveral and Merritt Island in Florida). At the military base are several Space Launch Complexes (SLC) used for launching payloads into polar orbits, with some of them currently active and more slated for future reactivation. Additionally, there are dozens of Intercontinental Ballistic Missile (ICBM) Launch Facilities (LF) at Vandenberg used for testing the missiles over the Pacific.
