It eventually became fully operational as the NORAD Combat Operations Center on Feb. 6, 1967.


Over the years, the installation came to house elements of NORAD, U.S. Strategic Command, U.S. Air Force Space Command and U.S. Northern Command. This combination of organizations became to be known as the Cheyenne Mountain Operations Center (CMOC). Many different centers supported the missions of aerospace warning and aerospace control of NORAD and provided warning of ballistic missile or air attacks against North America. NORAD's focus and facilities have both evolved to meet the possible threats of this century. On July 28, 2006, the Cheyenne Mountain Directorate was re-designated as the Cheyenne Mountain Division. It then made a mission to assist in establishing a NORAD and US Northern Command combined Command Center within the headquarters building at the Peterson Air Force Base in Colorado Springs, CO.
