Nuclear Weapon Yield
The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated. It is usually expressed as a ''TNT equivalent'', the standardized equivalent mass of trinitrotoluene (TNT) which would produce the same energy discharge if detonated, either in kilotonnes (symbol kt, thousands of tonnes of TNT), in megatonnes (Mt, millions of tonnes of TNT). It is also sometimes expressed in terajoules (TJ); an explosive yield of one terajoule is equal to . Because the accuracy of any measurement of the energy released by TNT has always been problematic, the conventional definition is that one kilotonne of TNT is held simply to be equivalent to 1012 calories. The yield-to-weight ratio is the amount of weapon yield compared to the mass of the weapon. The practical maximum yield-to-weight ratio for fusion weapons (thermonuclear weapons) has been estimated to six megatonnes of TNT per tonne of bomb ...

1980s In French Polynesia
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

French Nuclear Weapons Testing
France is one of the five "Nuclear Weapons States" under the Treaty on the Non-Proliferation of Nuclear Weapons, but is not known to possess or develop any chemical or biological weapons. France is the only member of the European Union to possess independent (non-NATO) nuclear weapons. France was the fourth country to test an independently developed nuclear weapon, doing so in 1960 under the government of Charles de Gaulle. The French military is currently thought to retain a weapons stockpile of around 290 operational (deployed) nuclear warheads, making it the fourth-largest in the world, speaking in terms of warheads, not megatons. The weapons are part of the country's ''Force de dissuasion'', developed in the late 1950s and 1960s to give France the ability to distance itself from NATO while having a means of nuclear deterrence under sovereign control. France did not sign the Partial Nuclear Test Ban Treaty, which gave it the option to conduct further nuclear tests until it ...

Hadès (missile)
The Hadès system was a short-range ballistic pre-strategic nuclear weapon system designed by France as a last warning before the use of strategic nuclear weapons in a prospective Soviet invasion of Western Europe. It was designed from July 1984 as a replacement for the tactical road-mobile Pluton missile. Initially 120 missiles were planned to be deployed. A wheeled trailer and launcher, each carrying two missiles in containers, was planned for deploying the Hadès. The original design had a range of 350 km, which was later increased to 450 km. The guidance system was an inertial platform which could be programmed to execute evasive maneuvers before hitting the target. A version designed to hit hardened underground targets also had a final guidance system which used a GPS-based digital system, resulting in a Circular Error Probable of only 5 m, compared to a CEP of 100 m for the standard version. Development Hadès began with project definition in 1975 as a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TN 81
The French ''airborne nuclear warheads (TN81)'' is a thermonuclear warhead carried by the Air-Sol Moyenne Portée (ASMP) medium-range air-to-surface missile, a component of the Force de frappe French nuclear deterrent. The warhead was introduced in 1988. By 1991, 80 warheads had been produced. Deployment: 60 warheads carried by the ASMP equipping the 60 Mirage 2000 N with the French Air Force and 20 Super Etendard of Naval Aviation. The TN81 has a yield of 300 kilotons It has been replaced by 54 TNA (Airborne nuclear warhead) thermonuclear warhead carried by the ASMPA equipping the Mirage 2000 N and Dassault Rafale.

Nuclear Fallout
Nuclear fallout is residual radioactive material that is created by the reactions producing a nuclear explosion. It is initially present in the mushroom cloud, radioactive cloud created by the explosion, and "falls out" of the cloud as it is moved by the atmosphere in the minutes, hours, and days after the explosion. The bulk of the radioactivity from nuclear fallout comes from fission products, which are created by the nuclear fission reactions of the nuclear device. Un-fissioned bomb fuel (such as plutonium and uranium), and radioactive isotopes created by neutron activation, make up a smaller amount of the radioactive content of fallout. The amount of fallout and its distribution is dependent on several factors, including the overall yield of the weapon, the fission yield of the weapon, the height of burst of the weapon, and meteorological conditions. Fallout can have serious human health consequences on both short- and long-term time scales, and can cause radioactive conta ...

TNT Equivalent
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. A ton of TNT equivalent is a unit of energy defined by convention to be (). It is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of trinitrotoluene (TNT). In other words, for each gram of TNT exploded, (or 4184 joules) of energy are released. This convention intends to compare the destructiveness of an event with that of conventional explosive materials, of which TNT is a typical example, although other conventional explosives such as dynamite contain more energy. A related concept is the physical quantity TNT-equivalent mass (or mass of TNT equivalent), expressed in the ordinary units of mass Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a body, until the discovery of the atom and particle physics. It was found that different atoms and diff ...

List Of Nuclear Weapons
This is a list of nuclear weapons listed according to country of origin, and then by type within the states. The United States, Russia, China and India are known to possess a nuclear triad, being capable to deliver nuclear weapons by land, sea and air. United States American nuclear weapons of all types – bombs, warheads, shells, and others – are numbered in the same sequence starting with the Mark 1 and () ending with the W91 (which was cancelled prior to introduction into service). All designs which were formally intended to be weapons at some point received a number designation. Pure test units which were experiments (and not intended to be weapons) are not numbered in this sequence. Early weapons were very large and could only be used as free fall bombs. These were known by "Mark" designators, like the Mark 4 which was a development of the Fat Man weapon. As weapons became more sophisticated they also became much smaller and lighter, allowing them to be used in many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Partial Nuclear Test Ban Treaty
The Partial Test Ban Treaty (PTBT), formally known as the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water, prohibited all nuclear weapons testing, test detonations of nuclear weapons except for those conducted underground nuclear weapons testing, underground. It is also abbreviated as the Limited Test Ban Treaty (LTBT) and Nuclear Test Ban Treaty (NTBT), though the latter may also refer to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which succeeded the PTBT for ratifying parties. Negotiations initially focused on a comprehensive ban, but that was abandoned because of technical questions surrounding the detection of underground tests and Soviet concerns over the intrusiveness of proposed verification methods. The impetus for the test ban was provided by rising public anxiety over the magnitude of nuclear tests, particularly tests of new thermonuclear weapons (hydrogen bombs), and the resulting nuclear fallout. A test ban was also se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
