TN 75
The TN 75 is a French-built 150kt thermonuclear warhead used on France's M45 and M51 submarine-launched ballistic missiles, carried by the last of the ''Redoutable'' class submarines, S616 '' Inflexible'', and by the ''Triomphant'' class submarines. The French Navy has 290 TN-75 warheads. It is a miniaturized, hardened and stealthy successor to the TN 71. Development began in 1987 and developmental testing of the warhead ended in 1991, but French president Jacques Chirac asserted in June 1995 (50 years after the Atomic bombings of Hiroshima and Nagasaki) that a full yield proof test was needed prior to deployment, causing an international outcry. Its first full-yield test was probably the 110 kt detonation on 1 October 1995 at Fangataufa. It will be succeeded by the TNO, the ''Tête nucléaire océanique''.

Atomic Bombings Of Hiroshima And Nagasaki
The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August 1945, respectively. The two bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in armed conflict so far. In the final year of World War II, the Allies prepared for a costly invasion of the Japanese mainland. This undertaking was preceded by a conventional and firebombing campaign that devastated 64 Japanese cities. The war in the European theatre concluded when Germany surrendered on 8 May 1945, and the Allies turned their full attention to the Pacific War. By July 1945, the Allies' Manhattan Project had produced two types of atomic bombs: "Fat Man", a plutonium implosion-type nuclear weapon; and "Little Boy", an enriched uranium gun-type fission weapon. The 509th Composite Group of the United States Army Air Forces was trained and equipped with the specialized Silverplate version of the ...

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] |
Strategic Oceanic Force
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. With the dissolution of the Attack Submarine Group of the Atlantic, ultimate formation regrouping submarines with conventional propulsion, on July 1 1999, the strategic fo ...

New York: Charles Scribner's and Sons; 1973. p104 is the designation of what used to be a triad of air-, sea- and land-based nuclear weapons intended for ''dissuasion'', the French term for deterrence. The French Nuclear Force, part of the French military, is the fourth largest nuclear-weapons force in the world, after the nuclear triad of the United States, the Russian Federation and the People's Republic of China. France has deactivated all land-based nuclear missiles. On 27 January 1996, France conducted its last nuclear test in the South Pacific and then signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT) in September 1996. In March 2008, French President Nicolas Sarkozy confirmed reports giving the actual size of France's nuclear arsenal and he announced that France would reduce its French Air Force-carried nuclear arsenal by ...

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 1995-19 ...

Fangataufa
Fangataufa (or Fangatafoa) is an uninhabited coral atoll in the eastern part of the Tuamotu Archipelago in French Polynesia. The atoll has been fully-owned by the French state since 1964. From 1966 to 1996 it was used as a nuclear test site by the French government. In total, 4 atmospheric and 10 underground nuclear explosions were carried out on the atoll. Geography The atoll is a coral outgrowth of a seamount which rises some from the seafloor, to a depth of . The seamount was formed 33.4 - 34.7 million years ago by the Pitcairn hotspot. The island is approx. long and wide. It has a lagoon area of and a land area of . It is located south of Moruroa atoll, east of Tematangi, southwest of the Gambier Islands and southeast of Tahiti. Access to the lagoon is through a pass lying SW of the northernmost point of the atoll; the channel has a width of about and a dredged depth of .

Nuclear Testing
Nuclear weapons tests are experiments carried out to determine nuclear weapons' effectiveness, yield, and explosive capability. Testing nuclear weapons offers practical information about how the weapons function, how detonations are affected by different conditions, and how personnel, structures, and equipment are affected when subjected to nuclear explosions. However, nuclear testing has often been used as an indicator of scientific and military strength. Many tests have been overtly political in their intention; most nuclear weapons states publicly declared their nuclear status through a nuclear test. The first nuclear device was detonated as a test by the United States at the Trinity site in New Mexico on July 16, 1945, with a yield approximately equivalent to 20 kilotons of TNT. The first thermonuclear weapon technology test of an engineered device, codenamed "Ivy Mike", was tested at the Enewetak Atoll in the Marshall Islands on November 1, 1952 (local date), also by the U ...

Fusion Bomb
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 deployed ...

TN 71
The TN 71 is a French-built thermonuclear warhead which was used on submarine-launched ballistic missiles in ''Redoutable'' class ballistic missile submarines. It has a yield of 150 kt. Entering service in 1985 on M4-B ballistic missiles, it was replaced at the end of October 1996 by the TN 75, which equips M45 missiles for France's ''Triomphant'' class of "new generation" ballistic missile submarines (SNLE-NG). There were 288 operational TN 71 warheads before its replacement in 1996, and 96 in 2001, but none were remaining by 2004, at which time it was withdrawn from service.
