Sentinel of Space found in Alaskan wilderness

Among the bears, moose, wolves and wolverines of Alaska’s interior is a silent sentinel of space – Clear Air Force Station. Its personnel keep an eye on things above for the sake of tactical warning of ballistic missile attacks against the U.S. and Canada and space situational awareness.

Clear AFS is an 11,500-acre installation about 80 miles southwest of Fairbanks. It is one of more than 20 geographically separated units within the 21st Space Wing, headquartered at Peterson Air Force Base, Colorado. Clear AFS is home to the Air Force’s 13th Space Warning Squadron and is the oldest missile warning site in North America.
