China And Weapons Of Mass Destruction
The People's Republic of China has developed and possesses weapons of mass destruction, including chemical and nuclear weapons. The first of China's nuclear weapons tests took place in 1964, and its first hydrogen bomb test occurred in 1967. Tests continued until 1996, when China signed the Comprehensive Test Ban Treaty (CTBT). China has acceded to the Biological and Toxin Weapons Convention (BWC) in 1984 and ratified the Chemical Weapons Convention (CWC) in 1997. The number of nuclear warheads in China's arsenal is a state secret. There are varying estimates of the size of China's arsenal. China was estimated by the Federation of American Scientists to have an arsenal of about 260 total warheads as of 2015, the fourth largest nuclear arsenal amongst the five nuclear weapon states acknowledged by the Treaty on the Non-Proliferation of Nuclear Weapons, and one of 320 total warheads by the '' SIPRI Yearbook 2020'', the third largest. According to some estimates by US intell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DF-41
The Dongfeng-41 (DF-41, CSS-20) () is a fourth-generation Chinese solid-fuelled road-mobile intercontinental ballistic missile operated by the People's Liberation Army Rocket Force (formerly the Second Artillery Corps). DF-41 is the fourth and the latest generation of the ''Dongfeng'' series strategic missiles developed by China. The missile was officially unveiled at the China National Day military parade on 1 October 2019. Design The missile reportedly has an operational range between . It is believed to have a top speed of Mach 25, and to be capable of MIRV delivery (up to 10). The development of the MIRV technology is reported to be in response to the deployment of the United States national missile defense system which degrades China's nuclear deterrence capability. The project started in 1986, and may now be coupled with the JL-2 program. Though there have been reports that the DF-41 can carry 6 to 10 warheads, analysts think it most likely carries only three warhea ...

Yumen City
Yumen (, literally, "Jade Gate,") is a city in western Gansu province, China. It is a county-level city with a population of 106,812 (2002 est.), and is part of Jiuquan "prefecture-level city" (a multi-county administrative unit). It is located on the Silk Road and is best known for its oil production. The city's name is often confused with the Yumen Guan or Jade Gate which is the frontier-pass of ancient times, the entrance to the old Silk Roads, which was situated not far to the west of Dunhuang. Although both Yumen City and Yumen Gate are within Jiuquan, the latter is some to the west from the former. In 2014, areas of the city were sealed off after a resident died of the bubonic plague. Districts of the city which house up to 100,000 were turned into quarantine zones. The city allocated 1 million yuan to be used for emergency vaccinations. History The site of Yumen was brought under Chinese control around the end of the 2nd century BCE. Yumen was known as 'Huiji' in the ...

Intercontinental Ballistic Missile
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order Of Battle
In modern use, the order of battle of an armed force participating in a military operation or campaign shows the hierarchical organization, command structure, strength, disposition of personnel, and equipment of units and formations of the armed force. Various abbreviations are in use, including OOB, O/B, or OB, while ORBAT remains the most common in the United Kingdom. An order of battle is distinct from a table of organisation, which is the intended composition of a given unit or formation according to the military doctrine of its armed force. Historically, an order of battle was the order in which troops were positioned relative to the position of the army commander or the chronological order in which ships were deployed in naval situations. As combat operations develop during a campaign, orders of battle may be revised and altered in response to the military needs and challenges. Also the known details of an order of battle may change during the course of executing the comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: *Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. *** Blast: A strong shock wave is provided by the detonation of the explosive. ***Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. ***Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag ...

Conventional Warfare
Conventional warfare is a form of warfare conducted by using conventional weapons and battlefield tactics between two or more states in open confrontation. The forces on each side are well-defined and fight by using weapons that target primarily the opponent's military. It is normally fought by using conventional weapons, not chemical, biological, radiological, or nuclear weapons. The general purpose of conventional warfare is to weaken or destroy the opponent's military, which negates its ability to engage in conventional warfare. In forcing capitulation, however, one or both sides may eventually resort to unconventional warfare tactics. History Formation of state The state was first advocated by Plato but found more acceptance in the consolidation of power under the Roman Catholic Church. European monarchs then gained power as the Catholic Church was stripped of temporal power and was replaced by the divine right of kings. In 1648, the powers of Europe signed the Treaty of ...

Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been dep ...

People's Liberation Army Rocket Force
The People's Liberation Army Rocket Force (PLARF; ), formerly the Second Artillery Corps (), is the strategic and tactical missile force of the People's Republic of China. The PLARF is the 4th branch of the People's Liberation Army (PLA) and controls China's arsenal of land-based ballistic missiles—both nuclear and conventional. The armed service branch was established on 1 July 1966 and made its first public appearance on 1 October 1984. The headquarters for operations is located at Qinghe, Beijing. The PLARF is under the direct command of the Chinese Communist Party's Central Military Commission (CMC). In total, China is estimated to be in possession of 320 nuclear warheads as of 2020, with an unknown number of them active and ready to deploy. In 2013, the United States Department of Defense estimated the Chinese active ICBM arsenal to range between 50 and 75 land and sea-based missiles. More recent intelligence assessments in 2019 put China's ICBM count at around 90 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
