Missile Alert Facility Model

This model depicts a Minuteman II alert facility. The complex was surrounded by a double fence with sensitive motion-detecting alarms. Each Launch Control Center (LCC) served 10 Minuteman missiles in individual hardened underground silos, typically spaced about 4 to 14 miles apart. Individual silos were not manned because the solid-fuel Minuteman II missiles could be stored almost indefinitely and launched from the LCC. They required only periodic maintenance and security visits.
