picture info	Île Longue 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 SNLE, the French 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 42 metres and has an area of 1.10 km2. 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 ...

picture info	Low-enriched Uranium Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (238U with 99.2739–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7202%), and uranium-234 (234U, 0.0050–0.0059%). 235U is the only nuclide existing in nature (in any appreciable amount) that is fissile with thermal neutrons. Enriched uranium is a critical component for both civil nuclear power generation and military nuclear weapons. The International Atomic Energy Agency attempts to monitor and control enriched uranium supplies and processes in its efforts to ensure nuclear power generation safety and curb nuclear weapons proliferation. There are about 2,000 tonnes of highly enriched uranium in the world, produced mostly for nuclear power, nuclear weapons, Nuclear marine propulsion, naval propulsion, and smaller quantiti ...

picture info	Pump-jet A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and a nozzle to direct the flow of water out of the pump.http://www.hamiltonmarine.co.nz/includes/files_cms/file/JetTorque%2008.pdf Design A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump and forced backwards through a nozzle. With the use of a ''reversing bucket'', reverse thrust can also be achieved for faring backwards, quickly and withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Racal Decca The Decca Radar company was a British manufacturer of radar systems. There were originally two divisions, Marine and Heavy Radar, with separate product lines. The latter was sold to Plessey in 1965, and the term "Decca Radar" normally refers to the Marine division. That division remained with Decca until 1979 when it purchased by Racal to form Racal-Decca. After a series of further mergers and purchases, from 2000 the division is part of Northrop Grumman. Decca is best known for its marine radars, starting with 1949's Type 159. Their most successful line was the 1970s Bridgemaster series which continued sales into the 2000s. Under Plessey, the company was particularly successful in the US pleasure boat market. The Heavy Radar division produced the AMES Type 80 radars for the Royal Air Force, and used that technology to develop the Decca HF200 height finder radar. This led to the Decca Air Surveillance Radar, which spawned a number of adaptations for civilian and military use. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	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 development ...

	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''.

picture info	Exocet The Exocet () is a French-built anti-ship missile whose various versions can be launched from surface vessels, submarines, helicopters and fixed-wing aircraft. Etymology The missile's name was given by M. Guillot, then the technical director at Nord Aviation. It is the French word for flying fish, from the Latin ''exocoetus'', a transliteration of the Greek name for the fish that sometimes flew into a boat: (''exōkoitos''), literally "lying down outside (, ), sleeping outside". Description The Exocet is built by MBDA, a European missile company. Development began in 1967 by Nord as a ship-launched weapon named the MM38. A few years later, Aerospatiale and Nord merged. The basic body design was based on the Nord AS-30 air-to-ground tactical missile. The sea-launched MM38 entered service in 1975, whilst the air-launched AM39 Exocet began development in 1974 and entered service with the French Navy five years later in 1979. The relatively compact missile is designed for at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	SSBN A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. The United States Navy's hull classification symbols for ballistic missile submarines are SSB and SSBN – the ''SS'' denotes submarine, the ''B'' denotes ballistic missile, and the ''N'' denotes that the submarine is nuclear powered. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect (see acoustic signature), thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence. The deployment of SSBNs is dominated by the United States and Russia (following the collapse of the Soviet Union). Smaller numbers are in service with France, the United Kingdom, China and India; North Kor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
