Keeping North America safe for half a century
                Attendees of the 50th anniversary rededication ceremony pay respect during the U.S. and Canadian national anthems at Cheyenne Mountain Air Force Station, Colo., April 15, 2016. After nearly five years of construction, Cheyenne Mountain AFS was declared fully operational April 20, 1966. Cheyenne Mountain AFS is owned by the 21st Space Wing at Peterson Air Force Base, Colo., and operated by the 721st Mission Support Group.
