Facilities

The Missile Alert Facility (MAF) consists of a buried and hardened Launch Control Center (LCC) and an above-ground Launch Control Support Building (LCSB). MAFs were formerly known as Launch Control Facilities (LCFs) but the terminology changed in 1992 with the inactivation of the Strategic Air Command (SAC). In addition, a MAF has a helicopter landing pad, a large radio tower, a large "top hat" HF antenna; a garage for security vehicles; recreational facilities, and one or two sewage lagoons. The entire site, except for the helicopter pad and sewage lagoons, is secured with a fence and security personnel. About a dozen
