Xian H-6
The Xian H-6 () is a twin-engine jet bomber of the Chinese People's Liberation Army Air Force (PLAAF). The H-6 is a license-built version of the Soviet Tupolev Tu-16 and remains the primary bomber aircraft of the People's Republic of China. Delivery of the Tu-16 to China began in 1958, and a license production agreement with the Soviets was signed in the late 1950s. By November 2020, the PLAAF had as many as 231. The latest variant of the H-6 is the H-6N, a heavily redesigned version capable of aerial refueling and carrying air-launched cruise missiles. According to the United States Department of Defense, this will give the PLAAF a long-range standoff offensive air capability with precision-guided munitions. History Having entered service with the Soviet Union in April 1952, the Tupolev Tu-16 was one the Soviets' earliest effective jet bombers with over 1,500 produced through 1962. Early in 1956, the Soviet Union agreed to license production of the Tu-16 to the People's Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People's Liberation Army Naval Air Force
The People's Liberation Army Naval Air Force (PLANAF; ) is the naval aviation branch of the People's Liberation Army Navy. Overview Historically, the PLANAF's main role has been to provide the navy's warships with air defense coverage. Part of the coastal defense doctrine was to have naval aircraft protecting the ships, hence the reason why many PLA ships of the 1960s–70s lacked long range anti-aircraft missiles or artillery. During the Sino-Vietnamese War, the PLANAF carried out many successful bombing and airstrike missions against Vietnamese territories, such as in the Spratly Islands. The 1960s saw a series of air combat sorties flown against the Republic of China Air Force. PLANAF pilots have been credited with many major victories over the Taiwanese in these small incidents. Historical aircraft operated by the PLANAF include the J-5, the J-6, and H-5. These aircraft have been retired by the late 1990s. Today, the PLANAF has a strength of around 26,000 personnel and ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Precision-guided Munition
A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the First Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped. Because the damage effects of explosive weapons decrease with distance due to an inverse cube law, even modest improvements in accuracy (hence reduction in miss distance) enable a target to be attacked with fewer or smaller bombs. Thus, even if some guided bombs miss, fewer air crews are put at risk and the harm to civilians and the amount of collateral damage may be reduced. The advent of precision-guided munitions resulted in the renaming of older, low-technology, bombs as "ungu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Division (military)
A division is a large military unit or Formation (military), formation, usually consisting of between 6,000 and 25,000 soldiers. In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps. Historically, the division has been the default combined arms unit capable of independent Military tactics, operations. Smaller combined arms units, such as the American regimental combat team (RCT) during World War II, were used when conditions favored them. In recent times, modern Western militaries have begun adopting the smaller brigade combat team (similar to the RCT) as the default combined arms unit, with the division they belong to being less important. While the focus of this article is on army divisions, in naval usage "division (naval), division" has a completely different meaning, referring to either an administrative/functional sub-unit of a department (e.g., fire control division of the weapons department) aboar ...

Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital flight. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight. Unlike cruise missiles, which are restricted to the atmosphere, it is advantageous for ballistic missiles to avoid the denser parts of the atmosphere and they may travel above the atmosphere into outer space. History The earliest form of ballistic missile dates from the 13th century with its use derived from the history of rockets. In the 14th century, the Ming Chinese navy used an early form of a ballistic missile weapon called the Huolongchushui in naval battles against enemy ships.Needham, Volume 5, Part 7, ...

Lop Nur
Lop Nur or Lop Nor (from a Mongolian name meaning "Lop Lake", where "Lop" is a toponym of unknown origin) is a former salt lake, now largely dried up, located in the eastern fringe of the Tarim Basin, between the Taklamakan and Kumtag deserts in the southeastern portion of the Xinjiang (Xinjiang Uygur Autonomous Region). Administratively, the lake is in Lop Nur town (), also known as Luozhong () of Ruoqiang County, which in its turn is part of the Bayingolin Mongol Autonomous Prefecture. The lake system into which the Tarim River and Shule River empty is the last remnant of the historical post-glacial Tarim Lake, which once covered more than in the Tarim Basin. Lop Nur is hydrologically endorheic – it is landbound and there is no outlet. The lake measured in 1928, but has dried up due to construction of dams which blocked the flow of water feeding into the lake system, and only small seasonal lakes and marshes may form. The dried-up Lop Nur Basin is covered with a salt cru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultural Revolution
The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a sociopolitical movement in the People's Republic of China (PRC) launched by Mao Zedong in 1966, and lasting until his death in 1976. Its stated goal was to preserve Chinese communism by purging remnants of capitalist and traditional elements from Chinese society. The Revolution marked the effective commanding return of Mao –who was still the Chairman of the Chinese Communist Party (CCP)– to the centre of power, after a period of self-abstention and ceding to less radical leadership in the aftermath of the Mao-led Great Leap Forward debacle and the Great Chinese Famine (1959–1961). The Revolution failed to achieve its main goals. Launching the movement in May 1966 with the help of the Cultural Revolution Group, Mao charged that bourgeois elements had infiltrated the government and society with the aim of restoring capitalism. Mao called on young people to "bombard the headqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
