Warren Air Force Base, Wyoming

An Air Force base with no runway, Warren is one of three bases in the USA that manage the nation’s fleet of land-based intercontinental ballistic missiles (ICBMs). As with the other two (North Dakota’s Minot AFB, and Montana’s Malmstrom AFB) Warren AFB is responsible for 150 Minuteman missiles in 150 unmanned silos, controlled by fifteen underground manned launch control centers. 19 of the missiles under Warren’s care are in southeastern Wyoming, and the rest are in adjacent Nebraska and Colorado. Warren AFB was the first operational ICBM base, dating back to the deployment of the Atlas missile program in 1958. The base employs more than 4,000 people (2015), and is the second largest employer in the state, after the University in Laramie.
