The secondary mission of Clear AFS is to provide Space Surveillance data on orbiting objects to the Air Force Space Command Space Control Center (SCC) also located in the Cheyenne Mountain Complex.
Clear Air Force Station has a rich history with very humble beginnings. The area's first permanent landmark was the Alaska Railroad whose line from Anchorage to Fairbanks was completed in 1918. The land was purchased by the Department of the Interior in 1949. Alaska Air Command soon designated it Clear Air Force Auxiliary Field, part of Ladd Field, for use as a gunnery range.
