Thunderchief
The Republic F-105 Thunderchief is an American supersonic fighter-bomber that served with the United States Air Force from 1958 to 1984. Capable of Mach 2, it conducted the majority of strike bombing missions during the early years of the Vietnam War; it was the only American aircraft to have been removed from combat due to high loss rates. It was originally designed as a single-seat, nuclear- attack aircraft; a two-seat Wild Weasel version was later developed for the specialized Suppression of Enemy Air Defenses (SEAD) role against surface-to-air missile sites. The F-105 was commonly known as the "Thud" by its crews. As a follow-on to the Mach 1 capable North American F-100 Super Sabre, the F-105 was also armed with missiles and a rotary cannon; however, its design was tailored to high-speed low-altitude penetration carrying a single nuclear weapon internally. First flown in 1955, the Thunderchief entered service in 1958. The single-engine F-105 could deliver a bomb load gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mikoyan-Gurevich MiG-17
The Mikoyan-Gurevich MiG-17 (russian: Микоян и Гуревич МиГ-17; NATO reporting name: Fresco) is a high-subsonic fighter aircraft produced in the Soviet Union from 1952 and was operated by air forces internationally. The MiG-17 was license-built in China as the Shenyang J-5 and Poland as the PZL-Mielec Lim-6. The MiG-17 is still being used by the North Korean air force in the present day and has seen combat in the Middle East and Asia. The MiG-17 was an advanced modification of the MiG-15 aircraft produced by the Soviet Union during the Korean War. Production of the MiG-17 was too late for use in that conflict and was first used in the Second Taiwan Strait Crisis in 1958. While the MiG-17 was designed to shoot down slower American bombers, it showed surprising success when used by North Vietnamese pilots to combat American fighters and fighter-bombers during the Vietnam War, nearly a decade after its initial design. This was due to the MiG-17 being more agile and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Republic Aviation
The Republic Aviation Corporation was an American aircraft manufacturer based in Farmingdale, New York, on Long Island, New York, Long Island. Originally known as the Seversky Aircraft Company, the company was responsible for the design and production of many important military aircraft, including its most famous products: World War II's Republic P-47 Thunderbolt, P-47 Thunderbolt fighter, the Republic F-84 Thunderjet, F-84 Thunderjet and Republic F-105 Thunderchief, F-105 Thunderchief jet fighters, as well as the Fairchild Republic A-10 Thunderbolt II, A-10 Thunderbolt II close-support aircraft.

Alexander Kartveli
Alexander Kartveli, born Aleksandre Kartvelishvili, ( ka, ალექსანდრე ქართველიშვილი) (September 9, 1896 – July 20, 1974) was a Georgian aeronautical engineer and an aviation pioneer in the United States. Kartveli achieved important breakthroughs in military aviation in the time of turbojet fighters. (June 30, 2002). Retrieved on October 17, 2011. Education and early career Alexander Kartvelishvili was born in Tbilisi, Georgia, which was part of Russian Empire at that time; into a noble Georgian family. (Georgians call themselves "kartvelebi", and his surname derives from "Kartveli", or Georgian). He graduated from the grammar school in Tbilisi in 1914. Later on, he decided to move to France, as one of several aviation engineer aspirants of Georgian origin, such as Michael Gregor. Kartvelishvili graduated in 1922 from the Institut supérieur de l'aéronautique et de l'espace in Paris.. He began working as a test pilot but was seri ...

North American F-100 Super Sabre
The North American F-100 Super Sabre is an American supersonic jet fighter aircraft that served with the United States Air Force (USAF) from 1954 to 1971 and with the Air National Guard (ANG) until 1979. The first of the Century Series of USAF jet fighters, it was the first USAF fighter capable of supersonic speed in level flight. The F100 was designed by North American Aviation as a higher-performance follow-on to the F-86 Sabre air-superiority fighter. Adapted as a fighter-bomber, the F-100 was superseded by the high-speed Republic F-105 Thunderchief for strike missions over North Vietnam. The F100 flew extensively over South Vietnam as the air force's primary close air-support jet until being replaced by the more efficient subsonic LTV A-7 Corsair II. The F100 also served in other NATO air forces and with other U.S. allies. In its later life, it was often referred to as the "Hun", a shortened version of "one hundred".

Wild Weasel
Wild Weasel is a code name given by the United States Air Force (USAF) to an aircraft of any type equipped with anti-radiation missiles and tasked with the suppression of enemy air defenses (SEAD): destroying the radar and surface-to-air missile (SAM) installations of enemy air defense systems.Hewitt, W.A''Planting the seeds of SEAD: The Wild Weasel in Vietnam'' School of Advanced Airpower Studies, Air University, Maxwell Air Force Base, Alabama, PhD Thesis. May 1992. Accessed 5 October 2009. The task of a Wild Weasel aircraft is to bait enemy anti-aircraft defenses into targeting it with their radars, whereupon the radar waves are traced back to their source, allowing the Weasel or its teammates to precisely target it for destruction. The Wild Weasel concept was developed by the USAF in 1965 during the Vietnam War after the introduction of Soviet SAMs and their downing of American strike aircraft participating in Operation Rolling Thunder in the skies over North Vietnam.

Republic F-84F Thunderstreak
The Republic F-84F Thunderstreak was an American swept-wing turbojet fighter-bomber. While an evolutionary development of the straight-wing F-84 Thunderjet, the F-84F was a new design. The RF-84F Thunderflash was a photo reconnaissance version. Development In 1948, a swept wing version of the F-84 was created with the hope of bringing performance to the level of the F-86. The last production F-84E was fitted with a swept tail, a new wing with 38.5 degrees of leading edge sweep and 3.5 degrees of anhedral, and a J35-A-25 engine producing 5,300 pound-force (23.58 kN) of thrust.Knaack 1978, p. 42. The aircraft was designated XF-96A. It flew on 3 June 1950 with Oscar P. Haas at the controls. Although the airplane was capable of 602 knots (693 mph, 1,115 km/h), the performance gain over the F-84E was considered minor. Nonetheless, it was ordered into production in July 1950 as the F-84F Thunderstreak. The F-84 designation was retained because th ...

McDonnell Douglas F-4 Phantom II
The McDonnell Douglas F-4 Phantom II is an American tandem two-seat, twin-engine, all-weather, long-range supersonic jet interceptor and fighter-bomber originally developed by McDonnell Aircraft for the United States Navy.Swanborough and Bowers 1976, p. 301. Proving highly adaptable, it entered service with the Navy in 1961 before it was adopted by the United States Marine Corps and the United States Air Force, and by the mid-1960s it had become a major part of their air arms. Phantom production ran from 1958 to 1981 with a total of 5,195 aircraft built, making it the most produced American supersonic military aircraft in history, and cementing its position as an iconic combat aircraft of the Cold War."F-4 Phantoms Phabulous 40th" Boeing.

Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...

Attack Aircraft
An attack aircraft, strike aircraft, or attack bomber is a tactical military aircraft that has a primary role of carrying out airstrikes with greater precision than bombers, and is prepared to encounter strong low-level air defenses while pressing the attack.Mortensen 1987, pp. 24–25. This class of aircraft is designed mostly for close air support and naval air-to-surface missions, overlapping the tactical bomber mission. Designs dedicated to non-naval roles are often known as ground-attack aircraft.Gunston 2009, p. 73. Fighter aircraft often carry out the attack role, although they would not be considered attack aircraft ''per se'', although fighter-bomber conversions of those same aircraft would be considered part of the class. Strike fighters, which have effectively replaced the fighter-bomber and light bomber concepts, also differ little from the broad concept of an attack aircraft. The dedicated attack aircraft as a separate class existed primarily during and after Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Dynamics F-111 Aardvark
The General Dynamics F-111 Aardvark is a retired supersonic, medium-range, multirole combat aircraft. Production variants of the F-111 had roles that included ground attack (e.g. interdiction), strategic bombing (including nuclear weapons capabilities), reconnaissance and electronic warfare. Developed in the 1960s by General Dynamics, the F-111 entered service in 1967 with the United States Air Force (USAF). The Royal Australian Air Force (RAAF) also ordered the type and began operating the F-111C variant in 1973. The F-111 pioneered several technologies for production aircraft, including variable-sweep wings, afterburning turbofan engines, and automated terrain-following radar for low-level, high-speed flight. Its design influenced later variable-sweep wing aircraft, and some of its advanced features have since become commonplace. The F-111 suffered a variety of problems during initial development. A fighter variant, the F-111B, was not accepted for production. The F-1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medal Of Honor
The Medal of Honor (MOH) is the United States Armed Forces' highest military decoration and is awarded to recognize American soldiers, sailors, marines, airmen, guardians and coast guardsmen who have distinguished themselves by acts of valor. The medal is normally awarded by the president of the United States, but as it is presented "in the name of the United States Congress", it is sometimes erroneously referred to as the "Congressional Medal of Honor". There are three distinct variants of the medal: one for the Department of the Army, awarded to soldiers, one for the Department of the Navy, awarded to sailors, marines, and coast guardsmen, and one for the Department of the Air Force, awarded to airmen and guardians. The Medal of Honor was introduced for the Department of the Navy in 1861, soon followed by the Department of the Army's version in 1862. The Department of the Air Force used the Department of the Army's version until they received their own distinctive version i ...

Speed Of Sound
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At , the speed of sound in air is about , or one kilometre in or one mile in . It depends strongly on temperature as well as the medium through which a sound wave is propagating. At , the speed of sound in air is about . The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior. In colloquial speech, ''speed of sound'' refers to the speed of sound waves in air. However, the speed of sound varies from substance to substance: typically, sound travels most slowly in gases, faster in liquids, and fastest in solids. For example, while sound travels at in air, it travels at in water (almost 4.3 times as fast) and at in iron (almost 15 times as fast). In an exceptionally stiff material such as diamond, sound travels a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
