Launch Control Facility Delta-01

This building functioned as topside support for the underground Launch Control Center. It acted as a multi-purpose facility to help personnel perform their mission.

Its primary purpose was to support the missileers stationed underground in carrying out their mission. Equipment such as a backup generator for auxiliary power, and environmental control provided backup support in the event of an attack. The building also contained a Security Control Center, where all security activities were coordinated and personnel would be processed when coming on site.

The topside structure also included living quarters, a day room, dining area and recreational room that Air Force support personnel used during their three-day tours of duty.

This site can only be viewed by guided tour only. For information on operating hours and seasons please click here...
