Air Defense Command
Aerospace Defense Command was a major command (military formation), 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. 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 ...

Group (military Aviation Unit)
A group is a military unit or a military formation that is most often associated with military aviation. Air and aviation groups The terms group and wing differ significantly from one country to another, as well as between different branches of a national defence force. Air groups vary considerably in size and status, but generally take two forms: * A unit of two to four squadrons, commanded by a lieutenant colonel, colonel, commander, naval captain or an equivalent rank. The United States Air Force (USAF), ''groupes'' of the French ''Armée de l'air'', ''gruppen'' of the German ''Luftwaffe'', United States Marine Corps Aviation, British Fleet Air Arm and some other naval air services usually follow this pattern. * A larger formation, often comprising more than 10 squadrons, commanded by a major general, brigadier general, commodore, rear admiral, air commodore or air vice-marshal. The air forces of many Commonwealth countries, such as the British Royal Air Force (RAF) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, maintain, and repair both aircraft and spacecraft. The border between space and the atmosphere has been proposed as above the ground according to the physical explanation that the air density is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. This border has been called the Kármán line. Overview In most industrial countries, the aerospace industry is a co-operation 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 Ag ...

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 a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the character f ...

An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage. The current composition o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joint Chiefs Of Staff
The Joint Chiefs of Staff (JCS) is the body of the most senior uniformed leaders within the United States Department of Defense, which advises the president of the United States, the secretary of defense, the Homeland Security Council and the National Security Council on military matters.

Bay Of Pigs Invasion
The Bay of Pigs Invasion (, sometimes called or after the Playa Girón) was a failed military landing operation on the southwestern coast of Cuba in April 1961 by the United States of America and the Cuban Democratic Revolutionary Front (DRF), consisting of Cuban exiles who opposed Fidel Castro's Cuban Revolution, Clandestine operation, clandestinely and directly financed by the U.S. government. The operation took place at the height of the Cold War, and its failure influenced relations between Cuba, the United States, and the Soviet Union.

Convair F-102 Delta Dagger
The Convair F-102 Delta Dagger is an interceptor aircraft designed and produced by the American aircraft manufacturer Convair. A member of the Century Series, the F-102 was the first operational supersonic interceptor and delta-wing fighter operated by the United States Air Force (USAF). The F-102 was designed in response to a requirement, known as the ''1954 Ultimate Interceptor'', produced by USAF officials during the late 1940s. Its main purpose was to be the backbone of American air defences and to intercept approaching Soviet strategic bomber fleets (primarily the Tupolev Tu-95) during the Cold War. The aircraft was designed alongside a sophisticated fire-control system (FCS); however, a simplified unit had to be adopted due to development difficulties. It used an internal weapons bay to carry both guided missiles and rockets. On 23 October 1953, the prototype YF-102 performed its maiden flight; however, it was destroyed in an accident only nine days later. The second prot ...
