Ellsworth Air Force Base, South Dakota

Ellsworth, located in western South Dakota, is one of only two B-1B bomber bases (the other is at Dyess AFB, TX). It was once a major intercontinental ballistic missile base, tending to the 150 silos in the area that contained Minuteman II missiles. As part of nuclear force reduction agreements, this missile field has been decommissioned, and its missiles have been removed from service (the last one was taken from its silo in 1994). The South Dakota Air and Space Museum is near the main gate.
