テ四e Longue
テ四e Longue (; French language, French for "Long Island"; ) is a peninsula of the roadstead of Brest in the department of Finistティre in the Brittany region. It is the base of the French SSBN, nuclear ballistic missile submarines (), and as such one of the most secretive and heavily defended places in France. Geography テ四e 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 Trテゥbテゥron. 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窶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, ...

Exocet
The Exocet () is a French-built anti-ship missile whose various versions can be launched from Warship, surface vessels, Submarine, submarines, Helicopter, 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 language, Greek name for the fish that sometimes flew into a boat: (''exナ耕oitos''), 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, Aテゥrospatiale, Aerospatiale and Nord merged. The basic body design was based on the AS-30, 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 yea ...

Ships Built In France
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%). Nomenclature Ships are typically larger than boats, but there is no ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

HMS Vigilant (S30)
HMS ''Vigilant'' is the third of the Royal Navy. ''Vigilant'' carries the Trident ballistic missile, the United Kingdom's nuclear deterrent. Construction ''Vigilant'' was built at Barrow-in-Furness by Vickers Shipbuilding and Engineering Ltd (now BAE Systems Submarine Solutions), was launched in October 1995, and commissioned in November 1996. Letter of last resort Peter Hennessy visited ''Vigilant'' for the '' Today programme'' on BBC Radio 4 in 2007. He reported that there is a grey safe in the control room that has an inner safe that only the commanding officer and executive officer can open. In that safe is a letter from the current Prime Minister of the United Kingdom, the letter of last resort, which contains guidance and orders to be followed should the United Kingdom be attacked with nuclear weapons. This letter is identical to the other three letters in similar safes on the other three ''Vanguard''-class submarines carrying the United Kingdom's nuclear deterre ...

SSBN
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. 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 ballistic missile submarines is dominated by the United States, Russia (following the collapse of the Soviet Union) and China. In fact, 70% of nuclear warheads in the USA are carried by ballistic missile submarines.Rafal, A. S. (2021).

Bulletin Of The Atomic Scientists
The ''Bulletin of the Atomic Scientists'' is a nonprofit organization concerning science and global security issues resulting from accelerating technological advances that have negative consequences for humanity. The ''Bulletin'' publishes content at both a free-access website and a bi-monthly, nontechnical academic journal. The organization has been publishing continuously since 1945, when it was founded by Albert Einstein and former Manhattan Project scientists as the ''Bulletin of the Atomic Scientists of Chicago'' immediately following the atomic bombings of Hiroshima and Nagasaki. The organization is also the keeper of the symbolic Doomsday Clock, the time of which is announced each January. Background One of the driving forces behind the creation of the ''Bulletin'' was the amount of public interest surrounding atomic energy and rapid technological change at the dawn of the Atomic Age. In 1945 the public interest in atomic warfare and weaponry inspired contributors to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 99.2732窶99.2752% natural abundance), uranium-235 (235U, 0.7198窶0.7210%), and uranium-234 (234U, 0.0049窶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. Low-enriched uranium (20% 235U, typically >85%) is used for the cores of many nuclear weapons, as well as compact reactors for naval propulsion and research, as well as breeder reactors. There are about 2,000 tonnes of highly enriched uranium in the world. Enrichment methods were first developed on a large scale by the Manhattan Project. Its gaseous diffusion method was used in the 1940s a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tテェte Nuclテゥaire Ocテゥanique
The ''Tテェte nuclテゥaire ocテゥanique'' ( English: Oceanic nuclear warhead) or TNO is a French thermonuclear warhead designed to equip the M51 ballistic missiles on the ''Triomphant''-class submarines. It has been in service since 2016, replacing the TN 75 warhead, originally designed for the M45, and which also equipped the ''M51'', pending the development and service entry of the ''TNO''. Designed and produced by the CEA's ''Military Applications Division (DAM)'', TNO warheads are an integral part of France's nuclear deterrent program. Nuclear materials As with all thermonuclear warheads, the explosive materials comprise three main elements: uranium, plutonium and tritium, all of which are of military grade. The highly enriched uranium 235 was produced at COGEMA's Pierrelatte plant and the highly enriched plutonium 239 at COGEMA's Marcoule plant. Both were produced before France definitively ceased uranium and plutonium production in 1997, the country having sufficient sto ...

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 On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki, respectively, during World War II. The aerial bombings killed between 150,000 and 246,000 people, most of whom were civili ...) that a full yield proof test was needed prior to deployment, causing an international outcry.
