PH 75
PH 75 was a military development program in France aimed at designing a nuclear-powered amphibious assault ship during the 1970s. Design work was never completed by the time the project was cancelled in 1981. History The role of providing air support for amphibious operations in the French Navy was left to the aging ''Arromanches'' (R 95), a World War II-era light carrier. PH 75 was envisioned as the replacement for the ''Arromanches''. Nuclear propulsion was selected to allow the vessel to operate with fewer support vessels and at longer ranges. Other roles were added to the program including command, rescue, and anti-submarine warfare Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are t .... Early plans were for completion of the first unit by 1981, but this proved unobtainab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mistral-class Amphibious Assault Ship
The ''Mistral'' class is a class of five amphibious assault ships built by France. Also known as helicopter carriers, and referred to as "projection and command ships" (french: links=no, bâtiments de projection et de commandement or BPC), a ''Mistral''-class ship is capable of transporting and deploying 16 NH90 or Tiger helicopters, four landing barges, up to 70 vehicles including 13 Leclerc tanks, or a 40-strong Leclerc tank battalion, and 450 soldiers. The ships are equipped with a 69-bed hospital, and are capable of serving as part of a NATO Response Force, or with United Nations or European Union peace-keeping forces. Three ships of the class are in service in the French Navy: , , and . A deal for two ships for the Russian Navy was announced by then French President Nicolas Sarkozy on 24 December 2010, and signed on 25 January 2011. On 3 September 2014, French President François Hollande announced the postponement of delivery of the first warship, , in response to the Ru ...

Aircraft Carriers Of France
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Helicopter Carrier Classes
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most commo ...

List Of Aircraft Carriers
This list of aircraft carriers contains aircraft carriers listed alphabetically by name. An aircraft carrier is a warship with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft, that serves as a seagoing airbase. Included in this list are ships which meet the above definition and had an official name (''italicized'') or designation (non-italicized), regardless of whether they were or were not ordered, laid down, completed, or commissioned. Not included in this list are the following: * Aircraft cruisers, also known as aviation cruisers, cruiser-carriers, flight deck cruisers, and hybrid battleship-carriers, which combine the characteristics of aircraft carriers and surface warfare ships, because they primarily operated helicopters or floatplanes and did not act as a floating airbase. Examples include the British s, Japanese s, French cruiser , Soviet s, and Italian s. Vessels which meet the criteria of an aircraft carrier b ...

Charles De Gaulle (R 91)
''Charles de Gaulle'' is the flagship of the French Navy. The ship, commissioned in 2001, is the tenth French aircraft carrier, the first French nuclear-powered surface vessel, and the only nuclear-powered carrier completed outside of the United States Navy. She is named after French president and general Charles de Gaulle. The ship carries a complement of Dassault Rafale M and E-2C Hawkeye aircraft, AS365F Dauphin Pedro, EC725 Caracal and AS532 Cougar helicopters for combat search and rescue, as well as modern electronics and Aster missiles. She is a CATOBAR-type carrier that uses two 75 m C13‑3 steam catapults of a shorter version of the catapult system installed on the US aircraft carriers, one catapult at the bow and one across the front of the landing area. As of July 2021, ''Charles de Gaulle'' is the only non-American carrier-vessel that has a catapult launch system, which has allowed for operation of F/A-18E/F Super Hornets and C-2 Greyhounds of the US Nav ...

Nuclear Reactor
A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction or nuclear fusion reactions. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. , the International Atomic Energy Agency reports there are 422 nuclear power reactors and 223 nuclear research reactors in operation around the world. In the early era of nuclear reactors (1940s), a reactor was known as a nuclear pile or atomic pile (so-called because the graphite moderator blocks of the first reactor were placed into a tall pi ...
