Foxbat
The Mikoyan-Gurevich MiG-25 (; NATO reporting name: Foxbat) is a supersonic interceptor and reconnaissance aircraft that is among the fastest military aircraft to enter service. Designed by the Soviet Union's Mikoyan-Gurevich bureau, it is an aircraft built primarily using stainless steel. It was to be the last aircraft designed by Mikhail Gurevich, before his retirement. The first prototype flew in 1964 and the aircraft entered service in 1970. Although it was capable of reaching Mach 3.2+, this would result in the engines accelerating out of control and needing replacement, therefore the operational top speed was limited to Mach 2.83."Intelligence: Big-Mouth Belenko" ''Time'', 11 October 1976.

Mach Number
The Mach number (M or Ma), often only Mach, (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Austrian physicist and philosopher Ernst Mach. \mathrm = \frac, where: * is the local Mach number, * is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and * is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas. The Mach number is primarily used to determine the approximation with which a flow can be treated as an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed U-2
The Lockheed U-2, nicknamed the "''Dragon Lady''", is an American single-engine, high–altitude reconnaissance aircraft operated by the United States Air Force (USAF) and the Central Intelligence Agency (CIA) since the 1950s. Designed for all-weather, day-and-night intelligence gathering at altitudes above ), the U-2 has played a pivotal role in aerial surveillance for decades. Lockheed Corporation originally proposed the aircraft in 1953. It was approved in 1954, and its first test flight was in 1955. It was flown during the Cold War over the Soviet Union, China, Vietnam War, Vietnam, and Cuba. In 1960, Francis Gary Powers, Gary Powers was 1960 U-2 incident, shot down in a CIA U-2C over the Soviet Union by a surface-to-air missile (SAM). Major Rudolf Anderson, Rudolf Anderson Jr. was shot down in a U-2 during the Cuban Missile Crisis in 1962.

Strategic Bomber
A strategic bomber is a medium- to long-range Penetrator (aircraft), penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombing, tactical bombers, Penetrator (aircraft), penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets (e.g., infrastructure, logistics, Military base, military installations, factories, etc.). In addition to strategic bombing, strategic bombers can be used for tactical bombing, tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China. The modern strategic bomber role appeared after Strategic bombing during World War II, strategic bombing was widely employed, and Atomic bombing ...

Soviet Air Force
The Soviet Air Forces (, VVS SSSR; literally "Military Air Forces of the Union of Soviet Socialist Republics"; initialism VVS, sometimes referred to as the "Red Air Force") were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II. The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92. Former Soviet Air Forces' assets were subsequently divided into several air forces of former Republics of the Soviet Union, Soviet republics, including the new Russian Air Force. The "Air March, March of the Pilots" was its marching song. Origins The first military aviation branch of Russia or any of the Soviet Union's constituent states was the short-lived Imperial Russian Air Service, founded in 1912 and disbanded in 1917 with the onset of the Bolshevik Revolution and ...

Lockheed SR-71 Blackbird
The Lockheed SR-71 "Blackbird" is a retired long-range, high-altitude, Mach 3+ strategic reconnaissance aircraft developed and manufactured by the American aerospace company Lockheed Corporation. Its nicknames include " Blackbird" and " Habu". The SR-71 was developed in the 1960s as a black project by Lockheed's Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the SR-71's innovative concepts. Its shape was based on the Lockheed A-12, a pioneer in stealth technology with its reduced radar cross section, but the SR-71 was longer and heavier to carry more fuel and a crew of two in tandem cockpits. The SR-71 was revealed to the public in July 1964 and entered service in the United States Air Force (USAF) in January 1966. During missions, the SR-71 operated at high speeds and altitudes (Mach 3.2 at ), allowing it to evade or outrace threats. If a surface-to-air missile launch was detected, the standard evasive ...

Mass Production
Mass production, also known as mass production, series production, series manufacture, or continuous production, is the production of substantial amounts of standardized products in a constant flow, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods. The term ''mass production'' was popularized by a 1926 article in the ''Encyclopædia Britannica'' supplement that was written based on correspondence with Ford Motor Company. ''The New York Times'' used the term in the title of an article that appeared before the publication of the ''Britannica'' article. The idea of mass production is applied to many kinds of products: from fluids and particulates handled in bulk (food, fuel, chemicals and mined minerals), to clothing, textiles, parts and assemblies of parts ( household appliances and automobiles). Some mass production techniques, such as standardized sizes and production lines, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Defection Of Viktor Belenko
On September 6, 1976, Lieutenant Viktor Belenko of the Soviet Air Defense Forces defected by flying his Mikoyan-Gurevich MiG-25, Mikoyan-Gurevich MiG-25P "Foxbat" aircraft from near Vladivostok in the Russian Far East, Far East of the Soviet Union to Hakodate Airport in Hokkaido Prefecture of Japan. Belenko's defection caused tension between Japan and the Soviet Union, especially after Japanese and American specialists disassembled and examined the aircraft. The examination revealed to the US that while impressive in speed, the MiG-25 was not the Air superiority fighter, superfighter that they had feared it to be. It was later returned to the Soviets while it was still disassembled with some parts missing. Belenko was granted political asylum in and later citizenship of the US, where he became a military consultant, public speaker, and businessman. Belenko later visited Moscow in 1995, after the end of the Soviet Union. Background During the Cold War, there were List of Cold ...

McDonnell Douglas F-15 Eagle
The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather fighter aircraft designed by McDonnell Douglas (now part of Boeing). Following reviews of proposals, the United States Air Force (USAF) selected McDonnell Douglas's design in 1969 to meet the service's need for a dedicated air superiority fighter. The Eagle took its maiden flight in July 1972, and entered service in 1976. It is among the most successful modern fighters, with over 100 victories and no losses in aerial combat, with the majority of the kills by the Israeli Air Force.Spick 2000, p. 127. The Eagle has been exported to many countries, including Israel, Japan, and Saudi Arabia. Although the F-15 was originally envisioned as a pure air superiority fighter, its design included a secondary ground-attack capability that was largely unused. It proved flexible enough that an improved all-weather strike derivative, the F-15E Strike Eagle, was later developed, entered service in 1989 and has been expor ...

Western World
The Western world, also known as the West, primarily refers to various nations and state (polity), states in Western Europe, Northern America, and Australasia; with some debate as to whether those in Eastern Europe and Latin America also constitute the West. The Western world likewise is called the Occident () in contrast to the Eastern world known as the Orient (). Definitions of the "Western world" vary according to context and perspectives; the West is an evolving concept made up of cultural, political, and economic synergy among diverse groups of people, and not a rigid region with fixed borders and members. Some historians contend that a linear development of the West can be traced from Greco-Roman world, Ancient Greece and Rome, while others argue that such a projection constructs a false genealogy. A geographical concept of the West started to take shape in the 4th century CE when Constantine the Great, Constantine, the first Christian Roman emperor, divided the Roman Em ...

Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct United States in the Vietnam War, US military involvement escalated from 1965 until its withdrawal in 1973. The fighting spilled into the Laotian Civil War, Laotian and Cambodian Civil Wars, which ended with all three countries becoming Communism, communist in 1975.
