Cheyenne Mountain Complex
The Cheyenne Mountain Complex is a United States Space Force installation and defensive bunker located in unincorporated El Paso County, Colorado, next to the city of Colorado Springs, at the Cheyenne Mountain Space Force Station, which hosts the activities of several tenant units. Also located in Colorado Springs is Peterson Space Force Base, where the North American Aerospace Defense Command (NORAD) and United States Northern Command (USNORTHCOM) headquarters are located. Formerly the center for the United States Space Command (USSC) and NORAD, the Complex monitored the airspace of Canada and the United States for missiles, space systems, and foreign aircraft through its worldwide early-warning system. Since 2008, NORAD and the USSC have been based at Peterson Space Force Base and the complex, re-designated as an Air Force station, is used for crew training and as a back-up command center if required. The military complex has included, in the past, many units of NORAD, US ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheyenne Mountain Space Force Station
Cheyenne Mountain Space Force Station (CMSFS) is located in Cheyenne Mountain on the Front Range of the Rocky Mountains in unincorporated El Paso County, Colorado, next to Colorado Springs, The Cheyenne Mountain Complex, an underground facility within Cheyenne Mountain SFS, was first built for the North American Aerospace Defense Command (NORAD) Combat Operations Center, though NORAD moved day-to-day operations to its headquarters on Peterson AFB in 2006. However, day-to-day operations were moved back in 2011 after a major overhaul and renovation. The location now supports U.S. Space Command's Missile Warning Center, other strategic warning and survivable capabilities, and provides a ready alternative operating location for NORAD's command center. Background Until 2006, Cheyenne Mountain was the center for the United States Space Command and NORAD which monitored the air space of Canada and the United States through a worldwide system for early warnings of missiles, spac ...

Bare Mountain (Massachusetts)
:''Alternate spelling: should not be confused with Bear Mountain.'' Bare Mountain, above sea level, is a prominent peak of the Holyoke Range of traprock mountains located in the Connecticut River Valley of Massachusetts, and part of the greater Metacomet Ridge that stretches from Long Island Sound to nearly the Vermont border.

Gaither Report
''Deterrence & Survival in the Nuclear Age'', commonly referred to as the Gaither report, is a US government report concerning strategy to prepare against the perceived threat of a nuclear attack from the Soviet Union. It was submitted to the United States National Security Council and the president in November 1957. It was prepared by a panel constituted as part of the Science Advisory Committee, at that time part of the Office of Defense Mobilization. The report's common name stems from the panel's first chairman H. Rowan Gaither. Preparation It was prepared by a panel constituted as part of the Science Advisory Committee, at that time part of the Office of Defense Mobilization. The report's common name stems from the panel's first chairman H. Rowan Gaither. He and the group were tasked by President Dwight D. Eisenhower with creating a strategy that would strengthen the US military defensive systems, and better prepare the US for a nuclear attack. The report was largely writ ...

Cold War
The Cold War was a period of global Geopolitics, geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which lasted from 1947 until the dissolution of the Soviet Union in 1991. The term ''Cold war (term), cold war'' is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and Nuclear arms race, nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, Economic sanctions, embargoes, and sports diplomacy. After the end of World War II in 1945, during which the US and USSR had been allies, the USSR installed satellite state, satellite governments in its occupied territories in Eastern Europe and N ...

Ent Air Force Base
Ent Air Force Base was a United States Air Force base located in the Knob Hill neighborhood of Colorado Springs, Colorado. A tent city, established in 1943 during construction of the base, was initially commanded by Major General Uzal Girard Ent (1900–1948), for whom the base is named. The base was opened in 1951. From 1957 to 1963, the base was the site of North American Aerospace Defense Command (NORAD), which subsequently moved to the Cheyenne Mountain Air Force Station. The base became the Ent Annex to the Cheyenne Mountain facility in 1975. The base was closed in 1976. The site later became the location of the United States Olympic Training Center, which was completed in July 1978. Background The first Air Defense Command was established on 26 February 1940, by the War Department. On 2 March 1940, it was put under the First Army Commander. It managed air defense within four geographic air districts. It was inactivated in mid-1944 when the threat of air attack see ...

CBRN Defense
Chemical, biological, radiological, and nuclear defense (CBRN defense) or Nuclear, biological, and chemical protection (NBC protection) is a class of protective measures taken in situations where chemical warfare, chemical, biological warfare, biological, radiological warfare, radiological, or nuclear warfare, nuclear (including terrorism) hazards may be present. CBRN defense consists of CBRN passive protection, contamination avoidance, and Weapon of mass destruction, weapons of mass destruction mitigation. A CBRN incident differs from a hazardous material incident in both scope and intent. CBRN incidents are responded to under the assumption that they are intentional and malicious; evidence preservation and perpetrator apprehension are of greater concern than with Hazmat team incidents. A 2011 forecast concluded that worldwide government spending on CBRN defense products and services would reach US$8.38 billion that year. Etymology In English language, English, the 19 ...

Blast Wave
In fluid dynamics, a blast wave is the increased pressure and flow resulting from the deposition of a large amount of energy in a small, very localised volume. The flow field can be approximated as a lead shock wave, followed by a similar subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding supersonically outward from an explosive core. It has a leading shock front of compressed gases. The blast wave is followed by a blast wind of negative gauge pressure, which sucks items back in towards the center. The blast wave is harmful especially to objects very close to the center or at a location of constructive interference. High explosives that detonate generate blast waves. Sources High-order explosives (HE) are more powerful than low-order explosives (LE). HE detonate to produce a defining supersonic over-pressurization shock wave. Sources of HE include trinitrotoluene (TNT), C-4, Semtex, nitroglycerin, and ammonium nitrate fuel oil (ANFO). LE deflagra ...

Nuclear Explosion
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction. The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device. Nuclear explosions are used in nuclear weapons and nuclear testing. Nuclear explosions are extremely destructive compared to conventional (chemical) explosives, because of the vastly greater energy density of nuclear fuel compared to chemical explosives. They are often associated with mushroom clouds, since any large atmospheric explosion can create such a cloud. Nuclear explosions produce high levels of ionizing radiation and Nuclear fallout, radioactive debris that is harmful to humans and can cause moderate to severe skin burns, eye damage, radiation sickness, radiation-induced cancer and possible ...
