NORAD

The North American Aerospace Defense Command, often shortened to just NORAD, is a combined organization of the United States and Canada that provides aerospace warning, air sovereignty, and protection for North America. Its central headquarters is located at Peterson Air Force Base in El Paso County, near Colorado Springs, Colorado. The underground operations center for NORAD is at Cheyenne Mountain. In conjunction with the United States Air Force, NORAD has appeared in many forms of speculative fiction, most notably the Stargate multimedia franchise. Stargate Command, which was the provincial authoritative body from Stargate SG-1 was based out of Cheyenne Mountain.

Marvel Universe
In the Marvel Universe, the fictional Valhalla Base served as a counterpart to Cheyenne Mountain. International terrorist Luchino Nefaria and his Ani-Men took control of Valhalla Base and implemented the Doomsmith Scenario, which gave Nefaria control over the country's entire missile defense network. The X-Men flew to Valhalla Base to fight Nefaria and the Ani-Men, and ultimately succeeded.

DC Universe
In the wake of the "Janus Directive", the espionage agency known as Checkmate suffered dramatic losses, including the destruction of their headquarters in Shelby, Virginia. Administrator Amanda Waller was removed from her position, and Sarge Steel relocated Checkmate to the Colorado NORAD facility.
