4729th Air Defense Group
The 4729th Air Defense Group is a discontinued United States Air Force organization. Its last assignment was with the Boston Air Defense Sector at Westover Air Force Base, Massachusetts, where it was discontinued in 1958. The group was formed to provide a single command and support organization for the two fighter interceptor squadrons of Air Defense Command, that were tenants at Westover, a Strategic Air Command (SAC) base. It was also assigned a maintenance squadron to perform aircraft maintenance. It was discontinued after the 324th Fighter-Interceptor Squadron moved in 1958, leaving only a single fighter squadron at Westover.

Air Defense Command
Aerospace Defense Command was a major command of the United States Air Force, responsible for continental air defense. 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. Air defense during World War II Continental United States air defense forces during World War II were initially under the command of the four air districts – Northeast Air District, Northwest Air District, Southeast Air District, and Southwest Air District. The air districts were established on 16 January 1941, before the Pearl Harbor attack. The four air districts also handled USAAF combat training with the Army Ground Forces and "organization a ...

Rocket (weapon)
In military terminology, a rocket is a self-propelled, generally unguided, weapon-system powered by a rocket engine. Though used primarily as medium- and long-range artillery systems, historically rockets have also seen considerable use as air-to-surface weapons, some use as air-to-air weapons, and even (in a few cases) as surface-to-air devices. Examples of modern surface-to-surface rocket systems include the Soviet BM-27 Uragan and the American M270 Multiple Launch Rocket System. In military parlance, a rocket differs from a missile primarily by lacking an active guidance system; early missiles became known as "guided rockets" or "guided missiles". Some rockets were developed as unguided systems and later upgraded to guided versions, like the GMLRS, and these generally retain the term "rocket" instead of becoming "missiles". Rockets or missiles that travel underwater, like the VA-111 Shkval, are known as "torpedoes", whatever their propulsion system. Early development The ...

Military Units And Formations Established In 1957
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ...

Aerospace Defense Command Units
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Research ...

Four Digit Groups Of The United States Air Force
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other h ...

Air Defense Groups Of The United States Air Force
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only i ...

List Of United States Air Force Aerospace Defense Command Interceptor Squadrons
The second iteration of Aerospace Defense Command (ADC) was established on 21 March 1946 as a component of the United States Army Air Forces, with the mission of planning for and executing the air defense of the United States. Air Defense Command (as it was known until 1968), was headquartered at Mitchel Army Airfield, New York. Types The growth and development of the ADC air defense system grew steadily throughout the Cold War era. Interceptors used by Air/Aerospace Defense Command were: * Republic F-47D/N Thunderbolt * North American F-51D/H Mustang * Northrop F-61C Black WidowWith the end of World War II, large numbers of wartime pistoned-engined fighters were allocated for air defense mission. The long range P-47N/P-51H models, developed for the invasion of Japan, were especially well-suited for the air defense role and were used into the mid-1950s by Air National Guard units. Generally P-47s were based east of the Mississippi River, while P-51s were stationed to the ...

Lockheed F-104 Starfighter
The Lockheed F-104 Starfighter is an American single-engine, supersonic air superiority fighter which was extensively deployed as a fighter-bomber during the Cold War. Created as a day fighter by Lockheed as one of the "Century Series" of fighter aircraft for the United States Air Force (USAF), it was developed into an all-weather multirole aircraft in the early 1960s and produced by several other nations, seeing widespread service outside the United States. After a series of interviews with Korean War fighter pilots in 1951, Kelly Johnson, then lead designer at Lockheed, opted to reverse the trend of ever-larger and more complex fighters and produce a simple, lightweight aircraft with maximum altitude and climb performance. On 4 March 1954, the Lockheed XF-104 took to the skies for the first time, and on 26 February 1958 the production fighter was activated by the USAF. Only a few months later it was pressed into action during the Second Taiwan Strait Crisis, when it was d ...

Semi-Automatic Ground Environment
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''. The processing power behind SAGE was supplied by the largest discrete component-based computer ever built, the IBM-manufactured AN/FSQ-7. Each SAGE Direction Center (DC) housed an FSQ-7 which occupied an entire floor, approximately not including supporting equipment. The FSQ-7 was actually two computers, "A" side and "B" side. Computer processing was switched from " ...

Data Link
A data link is the means of connecting one location to another for the purpose of transmitting and receiving digital information (data communication). It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver (two pieces of data terminal equipment) and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink. Types There are at least three types of basic data-link configurations that can be conceived of and used: * Simplex communications, most commonly meaning all communications in one direction only. * Half-duplex communications, meaning communications in both directions, but not both ways simultaneously. * Duplex communications, communications in both directions simultaneously. Aviation In civil aviation, a data-link system (known as Controller Pilot Data Link Communications) is used to send information between aircraft and air ...
