The Boeing E-3 Sentry is an American airborne early warning and control (AEW&C) aircraft developed by Boeing. E-3s are commonly known as AWACS. Derived from the Boeing 707 airliner, it provides all-weather surveillance, command, control, and communications, and is used by the United States Air Force, NATO, French Air and Space Force, Royal Saudi Air Force and Chilean Air Force. The E-3 has a distinctive rotating radar dome (rotodome) above the fuselage. Production ended in 1992 after 68 aircraft had been built.
The Semi-Automatic Ground Environment (SAGE) was a system of large computers and associated networking equipment that coordinated data from many radar sites and processed it to produce a single unified image of the airspace over a wide area. SAGE directed and controlled the NORAD response to a possible Soviet air attack, operating in this role from the late 1950s into the 1980s. Its enormous computers and huge displays remain a part of Cold War lore, and after decommissioning were common props in movies such as Dr. Strangelove and Colossus, and on science fiction TV series such as The Time Tunnel.
North American Aerospace Defense Command, known until March 1981 as the North American Air Defense Command, is a combined organization of the United States and Canada that provides aerospace warning, air sovereignty, and protection for Canada and the continental United States.
Aerospace Defense Command was a major command of the United States Air Force, responsible for air defense of the continental United States. It was activated in 1968 and disbanded in 1980. Its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated Aerospace rather than Air in 1968. Its mission was to provide air defense of the Continental United States (CONUS). It directly controlled all active measures, and was tasked to coordinate all passive means of air defense.
The Western Air Defense Sector (WADS) is a unit of the Washington Air National Guard located at Joint Base Lewis-McChord, Tacoma, Washington.
The 28th Air Division is an inactive United States Air Force organization. Its last assignment was with Air Defense Tactical Air Command at Tinker Air Force Base, Oklahoma. It was inactivated on 29 May 1992.
The Pacific Air Forces Regional Support Center, formerly the 611th Air Support Group, is a United States Air Force unit. It is assigned to the Eleventh Air Force, stationed at Joint Base Elmendorf-Richardson, Alaska.
Lewistown Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located 7.0 miles (11.3 km) east-southeast of Hilger, Montana. It was closed in 1971.
The SAGE radar stations of Air Defense Command were the military installations operated by USAF squadrons using the first automated air defense environment and networked by the SAGE System, a computer network. Most of the radar stations used the Burroughs AN/FST-2 Coordinate Data Transmitting Set (CDTS) to automate the operator environment and provide radar tracks to sector command posts at SAGE Direction Centers (DCs), e.g., the Malmstrom Z-124 radar station was co-located with DC-20. The sector/division radar stations were networked by DCs and Manual Control Centers to provide command, control, and coordination for ground-controlled interception of enemy aircraft by interceptors such as the F-106 developed to work with the SAGE System.
The Joint Surveillance System (JSS) is a joint United States Air Force and Federal Aviation Administration system for the atmospheric air defense of North America. It replaced the Semi Automatic Ground Environment (SAGE) system in 1983.
Perrin Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located 1.3 miles (2.1 km) southeast of North Texas Regional Airport, Texas. It was closed in 1971.
Dauphin Island Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located 1.9 miles (3.1 km) east of Dauphin Island, Alabama, near historic Fort Gaines (Alabama). It was closed in 1980.
Port Austin Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located 1.2 miles (1.9 km) south-southwest Port Austin, Michigan. It was closed in 1988 by the Air Force.
Lake Charles Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located 3.8 miles (6.1 km) southeast of Lake Charles, Louisiana. It was closed in 1995 by the Air Force, and turned over to the Federal Aviation Administration (FAA).
Elmendorf Air Force Base is a United States Air Force (USAF) facility in Anchorage, Alaska. Originally known as Elmendorf Field, it became Elmendorf Air Force Base after World War II.
Canadian Forces Station Beaverlodge is a closed General Surveillance Radar station. It is located 4.9 miles (7.9 km) east-northeast of Beaverlodge, Alberta. It was closed in 1988.
Canadian Forces Station Beausejour is a closed General Surveillance Radar station. It is located 45.1 miles (72.6 km) east-northeast of Winnipeg, Manitoba. It was closed in 1986.
An Air Defense Direction Center (ADDC) was a type of United States command post for assessing Cold War radar tracks, assigning height requests to available height-finder radars, and for "Weapons Direction": coordinating command guidance of aircraft from more than 1 site for ground-controlled interception. As with the World War II Aircraft Warning Service CONUS defense network, a "manual air defense system" was used through the 1950s Along with 182 radar stations at "the end of 1957, ADC operated … 17 control centers", and the Ground Observation Corps was TBD on TBD. With the formation of NORAD, several types of ADDCs were planned by Air Defense Command:
Continental Air Defense Command (CONAD) was a Unified Combatant Command of the United States Department of Defense, tasked with air defense for the Continental United States. It comprised Army, Air Force, and Navy components. It included Army Project Nike missiles anti-aircraft defenses and USAF interceptors. The primary purpose of continental air defense during the CONAD period was to provide sufficient attack warning of a Soviet bomber air raid to ensure Strategic Air Command could launch a counterattack without being destroyed. CONAD controlled nuclear air defense weapons such as the 10 kiloton W-40 nuclear warhead on the CIM-10B BOMARC. The command was disestablished in 1975, and Aerospace Defense Command became the major U.S. component of North American Air Defense Command (NORAD).
