Hadès (missile)
The Hadès system was a short-range ballistic pre-strategic nuclear weapon system designed by France, as a last warning before use of strategic nuclear weapons, in the perspective of a 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 250 km, which was later increased to 480 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-range Ballistic Missile
A short-range ballistic missile (SRBM) is a ballistic missile with a range of about or less. In past and potential regional conflicts, these missiles have been and would be used because of the short distances between some countries and their relative low cost and ease of configuration. In modern terminology, SRBMs are part of the wider grouping of theatre ballistic missiles, which includes any ballistic missile with a range of less than 3,500 km. Models See also * Tactical ballistic missile * Medium-range ballistic missile (MRBM) *Intermediate-range ballistic missile (IRBM) * Intercontinental ballistic missile (ICBM) * Anti-ship ballistic missile (ASBM) *Hypersonic cruise missile A cruise missile is a guided missile used against terrestrial or naval targets that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed.

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 d ...

Nuclear Artillery
Nuclear artillery is a subset of limited- yield tactical nuclear weapons, in particular those weapons that are launched from the ground at battlefield targets. Nuclear artillery is commonly associated with shells delivered by a cannon, but in a technical sense short-range artillery rockets or tactical ballistic missiles are also included. The development of nuclear artillery was part of a broad push by nuclear weapons countries to develop nuclear weapons which could be used tactically against enemy armies in the field (as opposed to strategic uses against cities, military bases, and heavy industry). Nuclear artillery was both developed and deployed by a small group of states, including the United States, the Soviet Union, and France. The United Kingdom planned and partially developed such weapon systems (the Blue Water missile and the Yellow Anvil artillery shell) but did not put them into production. A second group of states has derivative association with nuclear artille ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
President Of France
The president of France, officially the president of the French Republic (french: Président de la République française), is the executive head of state of France, and the commander-in-chief of the French Armed Forces. As the presidency is the supreme magistracy of the country, the position is the highest office in France. The powers, functions and duties of prior presidential offices, in addition to their relation with the Prime Minister of France, prime minister and Government of France, have over time differed with the various constitutional documents since the French Second Republic, Second Republic. The president of the French Republic is the ''Ex officio member, ex officio'' Co-Princes of Andorra, co-prince of Andorra, grand master of the Legion of Honour and of the Ordre national du Mérite, National Order of Merit. The officeholder is also honorary proto-canon of the Archbasilica of Saint John Lateran in Rome, although some have rejected the title in the past. ...

Jacques Chirac
Jacques René Chirac (, , ; 29 November 193226 September 2019) was a Politics of France, French politician who served as President of France from 1995 to 2007. Chirac was previously Prime Minister of France from 1974 to 1976 and from 1986 to 1988, as well as Mayor of Paris from 1977 to 1995. After attending the , Chirac began his career as a high-level civil servant, entering politics shortly thereafter. Chirac occupied various senior positions, including Minister of Agriculture (France), Minister of Agriculture and Minister of the Interior (France), Minister of the Interior. In 1981 French presidential election, 1981 and 1988 French presidential election, 1988, he unsuccessfully ran for president as the standard-bearer for the conservative Gaullist party Rally for the Republic. Chirac's internal policies initially included lower tax rates, the removal of price controls, strong punishment for crime and terrorism, and business privatisation. After pursuing these policies in his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Government
The Government of France (French: ''Gouvernement français''), officially the Government of the French Republic (''Gouvernement de la République française'' ), exercises executive power in France. It is composed of the Prime Minister, who is the head of government, as well as both senior and junior ministers. The Council of Ministers, the main executive organ of the Government, was established in the Constitution in 1958. Its members meet weekly at the Élysée Palace in Paris. The meetings are presided over by the President of France, the head of state, although the officeholder is not a member of the Government. The Government's most senior ministers are titled as ministers of state (''ministres d'État''), followed in protocol order by ministers (''ministres''), ministers delegate (''ministres délégués''), whereas junior ministers are titled as secretaries of state (''secrétaires d'État''). All members of the Government, who are appointed by the President following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Error Probable
In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability) is a measure of a weapon system's precision. It is defined as the radius of a circle, centered on the mean, whose perimeter is expected to include the landing points of 50% of the rounds; said otherwise, it is the median error radius. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, 50 will fall within a circle with a radius of 100 m around their average impact point. (The distance between the target point and the average impact point is referred to as bias.) There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, and R95, which is the radius of the circle where 95% of the values would fall in. The concept of CEP also plays a role when measuring the accuracy of a position obtained by a navig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inertial Navigation System
An inertial navigation system (INS) is a navigation device that uses motion sensors (accelerometers), rotation sensors ( gyroscopes) and a computer to continuously calculate by dead reckoning the position, the orientation, and the velocity (direction and speed of movement) of a moving object without the need for external references. Often the inertial sensors are supplemented by a barometric altimeter and sometimes by magnetic sensors ( magnetometers) and/or speed measuring devices. INSs are used on mobile robots and on vehicles such as ships, aircraft, submarines, guided missiles, and spacecraft. Other terms used to refer to inertial navigation systems or closely related devices include inertial guidance system, inertial instrument, inertial measurement unit (IMU) and many other variations. Older INS systems generally used an inertial platform as their mounting point to the vehicle and the terms are sometimes considered synonymous. Overview Inertial navigation is a self-c ...

Lunéville
Lunéville ( ; German, obsolete: ''Lünstadt'' ) is a commune in the northeastern French department of Meurthe-et-Moselle. It is a subprefecture of the department and lies on the river Meurthe at its confluence with the Vezouze. History Lunéville was a renowned resort in the 18th century, known as the capital of Lorraine. The grand Château de Lunéville, built in 1702 for Leopold, Duke of Lorraine to replace an older palace, was the residence of the duke of Lorraine until the duchy was annexed by France in 1766. The château was designed in the style of Versailles to satisfy Leopold's wife, Élisabeth Charlotte d'Orléans, the niece of Louis XIV, and became known as the "Versailles of Lorraine". It includes a chapel designed by Germain Boffrand. Leopold and his wife were the parents of Prince Charles Alexander of Lorraine and Francis I, Holy Roman Emperor (through him they were the grandparents of Marie Antoinette). The last duke of Lorraine was Stanislaus I, the form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Explosive
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives".
