Sepulveda
Air Guard Station
The Sepulveda ANG Station is located in Van Nuys, California. It is the home of the 261st Combat Communications Squadron.
Situated on approximately 26 acres, the Sepulveda ANG Station is bordered to the south by the Tillman Water Reclamation Plant and the Sepulveda Basin Recreational Area. The Sepulveda ANG Station was used as a Nike missile site by the U.S. Army from the mid-1950s until 1973. Three abandoned missile silos, which were used for air defense during the 1950s and 1960s, remain in place at the facility.
