Launch Pad & Location
Space Launch Complex 8
Vandenberg SFB, CA, USA
The Space Launch Complex 8 launch pad has hosted 10 rocket launches, including 10 orbital launch attempts. The Vandenberg SFB, CA, USA launch site has been the location for 887 total rocket launches.
Vandenberg Space 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.
Orbital ATK Minotaur IV Rocket
The Minotaur IV launch system is derived from the Peacekeeper ICBM. The first three stages are taken directly from decommissioned Peacekeeper missiles. A fourth stage, the Orion-38, is taken from the Pegasus family of air-launched rockets.
