île Longue (Gulf Of Morbihan)
Île Longue (; French for "Long Island"; ) is a peninsula of the roadstead of Brest in the department of Finistère in the Brittany region. It is the base of the French nuclear ballistic missile submarines (), and as such one of the most secretive and heavily defended places in France. Geography Île Longue is a peninsula on the commune of Crozon, attached to the Crozon peninsula. its altitude is and has an area of . To the north of the peninsula there are two small islands: Ile des Morts and Ile Trébéron. Originally the isthmus was a mere sand bank, and crossing was only possible at low tide. During the 19th century, it was improved with a stone pathway. During the construction of the strategic base (1967–1972), it was widened, made insubmersible, and changed into a big parking space. The peninsula is a stone plateau surrounded by cliffs. It harbours several water springs, which made human habitat possible. In the 19th century, three villages were built on the peninsu ...

German Occupation Of France During World War II
The Military Administration in France (; ) was an interim occupation authority established by Nazi Germany during World War II to administer the occupied zone in areas of northern and western France. This so-called ' was established in June 1940, and renamed ' ("north zone") in November 1942, when the previously unoccupied zone in the south known as ' ("free zone") was also occupied and renamed ' ("south zone"). Its role in France was partly governed by the conditions set by the Armistice of 22 June 1940 after the success of the leading to the Fall of France; at the time both French and Germans thought the occupation would be temporary and last only until Britain came to terms, which was believed to be imminent. For instance, France agreed that its soldiers would remain prisoners of war until the cessation of all hostilities. The "French State" (') replaced the French Third Republic that had dissolved in defeat. Though nominally extending its sovereignty over the whole co ...

Submarine-launched Ballistic Missile
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from Ballistic missile submarine, submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a thermonuclear weapon, nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles. Modern submarine-launched ballistic missiles are closely related to intercontinental ballistic missiles (ICBMs), with ranges of over , and in many cases SLBMs and ICBMs may be part of the same family of weapons. History Origins The first practical design of a submarine-based launch platform was developed by the Germans near the end of World War II involving a launch tube which contained a V-2 rocket, V-2 ballistic missile variant and was towed behind a submarine, known by the code-name V-2 rocket#Unfulfilled plans, ''Prüfs ...

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 (missile), 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 Multiple independently targetable reentry vehicle, 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 drag-reducing aerospike, 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 developme ...

Nuclear Warhead
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nuclear bombs have had yields between 10 tons (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). Yields in the low kilotons can devastate cities. A thermonuclear weapon weighing as little as can release energy equal to more than 1.2 megatons of TNT (5.0 PJ). Apart from the blast, effects of nuclear weapons include firestorms, extreme heat and ionizing radiation, radioactive nuclear fallout, an electromagnetic pulse, and a radar blackout. The first nuclear weapons were developed by the Allied Manhattan Project during World War II. Their production continues to require a large scientific and industrial complex, primari ...

Pyrotechnics
Pyrotechnics is the science and craft of creating fireworks, but also includes safety matches, oxygen candles, Pyrotechnic fastener, explosive bolts (and other fasteners), parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition. This trade relies upon self-contained and self-sustained exothermic chemical reactions to make heat, light, gas, smoke and/or sound. The name etymology, comes from the Greek words ''pyr'' (πυρ; 'fire') and ''technikós'' (τεχνικός; 'artistic'). Improper use of pyrotechnics could lead to List of pyrotechnic incidents, pyrotechnic accidents. People responsible for the safe storage, handling, and functioning of pyrotechnic devices are known as pyrotechnicians. Proximate pyrotechnics Explosions, flashes, smoke, flames, fireworks and other pyrotechnic-driven effects used in the entertainment industry are referred to as proximate pyrotechnics. Proximate refers to the pyrotechnic device's location relative to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusiliers Marins
The ''Fusiliers marins'' (lit. "Sailor Riflemen") are specialized sailors of the ''Marine nationale'' (French Navy). The ''Fusiliers marins'' serve primarily as the Navy’s security forces, providing protection for naval vessels and naval installations on land. Created in 1856 and with a modern strength of about 1,800 personnel, the ''Fusiliers marins'' should not be confused with the larger '' Troupes de Marine'' of the '' Armée de terre'' (French Army) who are often referred to as the French ‘marines.’ Missions The ''Fusiliers marins'' are tasked with: * the protection of sensitive sites of the Navy (Naval bases, French Naval Aviation, transmission stations etc.); * reinforcement of protection duties provided by Naval forces (maintaining order on board ship and the protection of naval vessels against attack). History of the French ''Fusiliers marins'' Creation of a specialized corps in 1856 These companies lacked specialized personnel trained for combat on lan ...

Force Océanique Stratégique
The Strategic Ocean Force () is one of two terms that describe the submarine component of the French Navy. Prior to 1999, FOST grouped ballistic missile submarines with a role in France's nuclear deterrent. Since 1999, they have been integrated with the Submarine Forces, which prior to that date was responsible solely for France's attack submarines. The two terms are now used separately, or in combination, for the combined force, which includes both ballistic missile and attack submarines, all of which are nuclear-powered. The French Strategic Ocean Force Command ALFOST was set up in 1972 under a Squadron Vice-Admiral. Generality The Strategic Ocean Force (), created on March 1, 1972, constitutes the principal composite of the Strategic French Nuclear Forces (). FOST was placed under the command of a Squadron Vice-Admiral (Officers of Admiral rank) (), hence the acronym ALFOST. With the dissolution of the Atlantic Attack Submarine Group, the submarines with convention ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Dock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History China The use of dry docks in China goes at least as far back as the 10th century A.D. In 1088, Song dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Europe Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous '' Tessarakonteres'' rowing ship. However a more recent survey by Goodchild and Forbes does not substantiate its existence. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. Renaiss ...
