Tête Nucléaire Océanique
''Tête nucléaire océanique'' (TNO or oceanic nuclear warhead) is a French thermonuclear warhead intended for use on the M51.2 submarine-launched ballistic missile, that is being developed and built by the Division of Military Applications (DAM) at France's Commissariat à l'énergie atomique et aux énergies alternatives (English: Atomic Energy and Alternative Energies Commission). It will be carried on Triomphant-class submarines. The TNO is intended to replace the currently deployed TN 75 warhead. Its commissioning was planned for 2015, when France's newest submarines, either ''Le Terrible or ''Le Vigilant'', will be one of the first to carry the warhead. Yield The TNO has a yield that is estimated to be 100 kilotons of TNT (kt). The warhead's charge is called "robust": less optimized than the TN 75 but with an improved reliability and life-span. Development of the technology in the warhead has benefited from the final series of French nuclear tests conducted in 1995-199 ...

Thermonuclear Weapon
A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits. Characteristics of nuclear fusion reactions make possible the use of non-fissile depleted uranium as the weapon's main fuel, thus allowing more efficient use of scarce fissile material such as uranium-235 () or plutonium-239 (). The first full-scale thermonuclear test was carried out by the United States in 1952; the concept has since been employed by most of the world's nuclear powers in the design of their weapons. Modern fusion weapons consist essentially of two main components: a nuclear fission primary stage (fueled by or ) and a separate nuclear fusion secondary stage containing thermonuclear fuel: the heavy hydrogen isotopes deuterium and tritium, or in modern weapons lithium deuteri ...

Moruroa
Moruroa (Mururoa, Mururura), also historically known as Aopuni, is an atoll which forms part of the Tuamotu Archipelago in French Polynesia in the southern Pacific Ocean. It is located about southeast of Tahiti. Administratively Moruroa Atoll is part of the commune of Tureia, which includes the atolls of Tureia, Fangataufa, Tematangi and Vanavana. France undertook nuclear weapon tests between 1966 and 1996 at Moruroa and Fangataufa, causing international protests, notably in 1974 and 1995. The number of tests performed on Moruroa has been variously reported as 175 and 181. History Ancient Polynesians knew Mururoa Atoll by the ancestral name of Hiti-Tautau-Mai. The first recorded European to visit this atoll was Commander Philip Carteret on HMS ''Swallow'' in 1767, just a few days after he had discovered Pitcairn Island. Carteret named Mururoa "Bishop of Osnaburgh Island". In 1792, the British whaler was wrecked here, and it became known as Matilda's Rocks. Frederick Will ...

List Of Nuclear Tests
Nuclear weapons testing is the act of experimentally and deliberately firing one or more nuclear devices in a controlled manner pursuant to a military, scientific or technological goal. This has been done on test sites on land or waters owned, controlled or leased from the owners by one of the eight nuclear nations: the United States, the Soviet Union, the United Kingdom, France, China, India, Pakistan and North Korea, or has been done on or over ocean sites far from territorial waters. There have been 2,121 tests done since the first in July 1945, involving 2,476 nuclear devices. As of 1993, worldwide, 520 atmospheric nuclear explosions (including 8 underwater) have been conducted with a total yield of 545 megaton (Mt): 217 Mt from pure fission and 328 Mt from bombs using fusion, while the estimated number of underground nuclear tests conducted in the period from 1957 to 1992 is 1,352 explosions with a total yield of 90 Mt. Very few unknown tests are suspected ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force Océanique Stratégique
The Strategic Ocean Force (french: Force océanique stratégique, FOST) has been the synonym of the French Submarine Forces since 1999, which the commandant commands the ensemble related to, along with the squadron of nuclear attack submarine (french: Escadrille des Sous-Marins Nucléaires d'Attaque, ESNA). The French Strategic Ocean Force Command ALFOST was set up in 1972 under a Squadron Vice-Admiral. Generality The Strategic Ocean Force (french: Force océanique stratégique, FOST), created on March 1 1972, constitutes the principal composite of the Strategic French Nuclear Forces (french: Force de dissuasion Nucléaire Française, FNS). FOST has been placed under the command of a Squadron Vice-Admiral (Officers of Admiral rank) (french: L'Officier général de marine), hence the acronym ALFOST.

Radiographic Equipment
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography ("diagnostic" and "therapeutic") and industrial radiography. Similar techniques are used in airport security (where "body scanners" generally use backscatter X-ray). To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and is projected toward the object. A certain amount of the X-rays or other radiation is absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector). The generation of flat two dimensional images by this technique is called projectional radiography. In computed tomography (CT scanning) an X-ray source and its associated detectors rotate around the sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Mégajoule
Laser Mégajoule (LMJ) is a large laser-based inertial confinement fusion (ICF) research device near Bordeaux, France, built by the French nuclear science directorate, Commissariat à l'Énergie Atomique (CEA). Laser Mégajoule plans to deliver over 1 MJ of laser energy to its targets, compressing them to about 100 times the density of lead. It is about half as energetic as its US counterpart, the National Ignition Facility (NIF). Laser Mégajoule is the largest ICF experiment outside the US. Laser Mégajoule's primary task will be refining fusion calculations for France's own nuclear weapons. A portion of the system's time is set aside for materials science experiments. Construction of the LMJ took 15 years and cost 3 billion euros. It was declared operational on 23 October 2014, when it ran its first set of nuclear-weapon-related experiments. Description Laser Mégajoule uses a series of 22 laser "beamlines". They are arranged into four separate "halls", two each side- ...

TNT Equivalent
TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion. The is a unit of energy defined by that convention to be , which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT. In other words, for each gram of TNT exploded, (or 4184 joules) of energy is 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. Kiloton and megaton The "kiloton (of TNT)" is a unit of energy equal to 4.184 terajoules (). The "megaton (of TNT)" is a unit of energy equal to 4.184 petajoules (). The kiloton and megaton of TNT have traditionally been used to describe the energy output, and hence the destructive power, of a nuclear weapon. The TNT equivalent appears in various nuclear weapon control treaties, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M51 (missile)
The M51 SLBM is a French submarine-launched ballistic missile, built by ArianeGroup, and deployed with the French Navy. Designed to replace the M45 SLBM (In French terminology the MSBS – ''Mer-Sol-Balistique-Stratégique'' "Sea-ground-Strategic ballistic"), it was first deployed in 2010. Each missile carries six to ten independently targetable TN 75 thermonuclear warheads. The three-stage engine of the M51 is directly derived from the solid propellant boosters of Ariane 5. Like other blunt-nosed SLBM examples, such as the Trident D5, the M51 uses an extensible aerospike in the nose. The missiles are a compromise over the M5 SLBM design, which was to have a range of and carry ten new-generation tête nucléaire océanique' ("oceanic nuclear warhead") MIRVs. Design work on the M5 started in the late 1980s by Aérospatiale, before the programme was renamed the M51 in 1996, when development costs decreased by 20 percent. The M51 entered service in 2010.
