North American Aerospace Defense Command (NORAD) was a joint American-Canadian organization intended to provide aerospace warning, air sovereignty, and defense for the two countries before the Great War. Its headquarters were located underneath Cheyenne Mountain in Colorado Springs, Colorado.
In 1958, the United States government offered the British government protection of their Canadian domain, in case of a Soviet attack on North America. In 1961, the NORAD headquarters were established inside of Cheyenne Mountain, in Colorado Springs, Colorado. NORAD had been on high alert on many times such as the first Chinese atomic detonation in 1962. Throughout the 'Cold War' between the United States and it's new enemy China , Lockreed P-80s were a regular sight in the skies over the U.S. due to the organization's dedication againist preventing nuclear attack.
Throughout it's existance, NORAD had had some major blimps that would have potentially caused Nuclear War. In 1964, a NORAD radar station radioed in that they had tracked a potentially enemy bomber over the West Coast of the United States. Before the ICBMs could be launched, the same radar installation radioed in that the bomber was a friendly B-52 bomber. The most famous mishap was in 1980, when another radar installation tracked what it thought was potentially an enemy jet. However, it turned out that the 'enemy' jet was actually a passenger plane; which had been shot down in the chaos.
In the 2050's, tired of having dangerous mishaps; NORAD installed A.W.S. (Advanced Warning System) into it's Cheyenne Mountain complex. One of newest ZAX units availiable to the United States Military, A.W.S. had a pin-point accuracy when it came to missile defense, treating each movement with extreme tactical manner.
In the 2060s, the fighter jets were largely replaced by a system of anti-ballistic missile defenses, both ground and space-based, in response to the emergence of intercontinental ballistic missiles (ICBMs). During the Great War, Cheyenne Mountain was pulverized by some of the most powerful thermonuclear weapons in the Chinese arsenal.
NORAD had, for the most part, ceased to exist after the Great War, but its equipment remained largely intact throughout North America. Radar arrays and buildings such as offices laid across the Wasteland, usually being settled by ignorant wastelanders who did not pay attention to their old importance.
