517th Air Defense Group
The 517th Air Defense Group is a disbanded United States Air Force organization. Its last assignment was with the 4711th Air Defense Wing at Ethan Allen Air Force Base, Vermont. It was inactivated on 18 August 1955. The group was originally activated as a support unit for a bombardment group at the end of World War II in Italy and then redeployed to the Caribbean, where it supported units redeploying from Europe until it was inactivated in 1945. The group was activated once again in 1953, when ADC established it as the headquarters for a dispersed fighter-interceptor squadron and the medical, maintenance, and administrative squadrons supporting it. It was replaced in 1955 when ADC transferred its mission, equipment, and personnel to the 14th Fighter Group in a project that replaced air defense groups commanding fighter squadrons with fighter groups with distinguished records during World War II.

Air Transport Command Emblem
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 in ...

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waller Field
Waller Air Force Base is a former United States Air Force World War II air base located in northeastern Trinidad. It is located about 5 miles (8 km) southwest of Valencia south of the Churchill-Roosevelt Highway and roughly 32 km from the capital city Port of Spain. History The American rights to the airfield were obtained via the Destroyers for Bases Agreement in September 1940, when the United States transferred fifty destroyers to Great Britain in exchange for Army and Navy base rights on British possessions in the Americas. In 1941, Trinidad was alarmed by a large number of Nazi U-boats prowling off its coastline, intent on disrupting British shipping in the Caribbean Sea, and using the Vichy French controlled island of Martinique as a possible supply facility. Although the first United States Army personnel arrived on Trinidad on 24 April 1941, it was only after the United States' entry into the war, that Allied planners, in early 1942, decided to counter the Nazi ...

Caserta
Caserta () is the capital of the province of Caserta in the Campania region of Italy. It is an important agricultural, commercial, and industrial ''comune'' and city. Caserta is located on the edge of the Campanian plain at the foot of the Campanian Subapennine mountain range. The city is best known for the Royal Palace of Caserta. History Anciently inhabited by Osco- Samnite tribes, modern Caserta was established around the defensive tower built in Lombard times by Pando, Prince of Capua. Pando destroyed the original city around 863. The tower is now part of the Palazzo della Prefettura that was once the seat of the counts of Caserta, as well as a royal residence. The original population moved from Casertavecchia (former bishopric seat) to the current site in the sixteenth century. Casertavecchia was built on the Roman town of ''Casa Irta'', meaning "home village located above" and later contracted as "Caserta". The city and vicinity were the property of the Acquaviva fam ...

Air Transport Command
Air Transport Command (ATC) was a United States Air Force unit that was created during World War II as the strategic airlift component of the United States Army Air Forces. It had two main missions, the first being the delivery of supplies and equipment between the United States and the overseas combat theaters; the second was the ferrying of aircraft from the manufacturing plants in the United States to where they were needed for training or for operational use in combat. ATC also operated a worldwide air transportation system for military personnel. Inactivated on 1 June 1948, Air Transport Command was the precursor to what became the Military Air Transport Service in 1948 and was redesignated Military Airlift Command (MAC) in 1966. It was consolidated with MAC in 1982, providing a continuous history of long range airlift through 1992 when the mission was transferred to today's Air Mobility Command.

North American F-86 Sabre
The North American F-86 Sabre, sometimes called the Sabrejet, is a transonic jet fighter aircraft. Produced by North American Aviation, the Sabre is best known as the United States' first swept-wing fighter that could counter the swept-wing Soviet MiG-15 in high-speed dogfights in the skies of the Korean War (1950–1953), fighting some of the earliest jet-to-jet battles in history. Considered one of the best and most important fighter aircraft in that war, the F-86 is also rated highly in comparison with fighters of other eras. Although it was developed in the late 1940s and was outdated by the end of the 1950s, the Sabre proved versatile and adaptable and continued as a front-line fighter in numerous air forces. Its success led to an extended production run of more than 7,800 aircraft between 1949 and 1956, in the United States, Japan, and Italy. In addition, 738 carrier-modified versions were purchased by the US Navy as FJ-2s and -3s. Variants were built in Canada and Austr ...

Folding-Fin Aerial Rocket
The Mk 4 Folding-Fin Aerial Rocket (FFAR), also known as "Mighty Mouse", was an unguided rocket used by United States military aircraft. It was 2.75 inches (70 mm) in diameter. Designed as an air-to-air weapon for interceptor aircraft to shoot down enemy bombers, it primarily saw service as an air-to-surface weapon. The FFAR has been developed into the modern Hydra 70 series, which is still in service. History The advent of jet engines for fighters and bombers posed new problems for interceptors. With closing speeds of 1,500 ft/s (457 m/s) or more for head-on interceptions, the time available for a fighter pilot to successfully target an enemy aircraft and inflict sufficient damage to bring it down was increasingly small. Wartime experience had shown that .50 caliber (12.7 mm) machine guns were not powerful enough to reliably down a bomber, certainly not in a single volley, and heavy autocannons did not have the range or rate of fire to ensure a hit.

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

F-51 Mustang
The North American Aviation P-51 Mustang is an American long-range, single-seat fighter aircraft, fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in April 1940 by a team headed by James H. Kindelberger of North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 Warhawk, Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October. The Mustang was designed to use the Allison V-1710 engine, which had limited high-altitude performance in its earlier variants. The aircraft was first flown operationally by the RAF a ...
