NORTH AMERICAN AEROSPACE DEFENCE COMMAND (NORAD)
North American Aerospace Defense Command (NORAD) is a joint organization of the United States and Canada that provides aerospace warning and control for North America. It was founded on May 12, 1958, as the North American Air Defense Command. Since 1963, NORAD's main technical facility has been the Cheyenne Mountain Operations Center in Colorado, and for this reason NORAD is sometimes unofficially referred to as Cheyenne Mountain.
NORAD's headquarters facilities in Colorado are administered by the U. S. Air Force under the command of the 721st Mission Support Group, part of the 21st Space Wing, headquartered at Peterson Air Force Base. NORAD's forces consist of the Alaskan NORAD Region/Eleventh Air Force, Canadian NORAD Region, and Continental NORAD Region.
MISSSION
" NORAD continuously provides worldwide detection, validation and warning of a ballistic missile attack on North America and maintains continental detection, validation, warning and aerospace control of air-breathing threats to North America, to include peacetime alert levels and appropriate aerospace defense measures to respond to hostile actions against North America. "
HISTORY
The growing perception of the threat of long-range Soviet strategic bombers armed with nuclear weapons brought the U. S. and Canada into closer cooperation for air defense. In the early 1950s the U. S. and Canada agreed to construct a series of radar stations across North America to detect a Soviet attack over the Arctic. The first series of radars was the Pinetree Line, completed in 1954 and consisting of 33 stations across southern Canada. However, technical defects in the system led to more radar networks being built. In 1957, the McGill Fence was completed; it consisted of Doppler radar for the detection of low-flying craft. This system was roughly 300 miles north of the Pinetree Line along the 55th parallel. The third joint system was the Distant Early Warning Line (DEW Line), also completed in 1957. This was a network of 57 stations along the 70th parallel. The systems gave around three hours warning of bomber attack before they could reach any major population center.
The command and control of the massive system then became a significant challenge. In 1957, with the U. S. and Canada established an integrated command, the North American Air Defense Command. On September 12, operations commenced in Colorado.
By the early 1960s, about 250, 000 personnel were involved in the operation of NORAD. The emergence of the intercontinental ballistic missile (ICBM) and submarine-launched ballistic missile (SLBM) threat in the early 1960s was something of a blow. In response, a space surveillance and missile warning system was constructed to provide worldwide space detection, tracking and identification. The extension of NORAD's mission into space led to a name change, the North American Aerospace Defense Command in March 2007.

From 1963, the size of the U. S. Air Force was reduced, and obsolete sections of the radar system were shut down. However, there was increased effort to protect against an ICBM attack; two underground operations centers were set up, the main one inside Cheyenne Mountain and an alternate at North Bay, Ontario. By the early 1970s, the acceptance of mutual assured destruction doctrine led to a cut in the air defense budget and the repositioning of NORAD's mission to ensuring the integrity of airspace during peacetime. There followed significant reductions in the air defense system until the 1980s, when, following the 1979 Joint US-Canada Air Defense Study (JUSCADS) the need for the modernization of air defenses was accepted—the DEW Line was to be replaced with an improved Arctic radar line called the North Warning System (NWS); there was to be the deployment of Over-the-Horizon Backscatter (OTH-B) radar; the assignment of more advanced fighters to NORAD, and the greater use of Airborne Warning and Control System (AWACS) aircraft from Tinker Air Force Base in Oklahoma or Elmendorf Air Force Base in Alaska. These recommendations were accepted by the governments in 1985. The United States Space Command was formed in September 1985 as an adjunct but not a component of NORAD.
POST-COLD WAR
At the end of the Cold War NORAD reassessed its mission. To avoid cutbacks, from 1989 NORAD operations expanded to cover counter-drug operations, especially the tracking of small aircraft. But the DEW line sites were still replaced, in a scaled-back fashion by the North Warning System radars between 1986 and 1995. The Cheyenne Mountain site was also upgraded. However, none of the proposed OTH-B radars is currently in operation.
POST-SEPTEMBER 11 ATTACKS
After September 11, the NORAD mission evolved to include monitoring of all aircraft flying in the interior of the United States. On July 28, 2006, military officials announced that NORAD's day-to-day operations would be consolidated, for purposes of efficiency, in an ordinary building at Peterson Air Force Base in nearby Colorado Springs. The mountain will be kept only as a backup in " warm standby, " though fully operational and staffed with support personnel should the need arise. NORAD officials stated that the same surveillance work can be continued without the security the facility provides. They emphasized that they are no longer concerned about a halt to their operations from an intercontinental nuclear attack.
