Cassard-class Frigate
The ''Cassard'' class (Type F70 AA) was a Ship class, class of two anti-air warfare destroyers of the French Navy introduced in the latter 1980s/early 1990s. The class was an air defence variant of the . The two classes have a different armament and propulsion system mounted on an identical hull. Their primary role was to provide air cover for a fleet, an aeronaval group, a convoy & a littoral point. Their secondary role was to manage air assets coordination & aircraft control for the force, especially through Link 16.They can also be used for research, identification or presence missions. Both ships were assigned to the ''Force d'Action Navale.''Gardiner and Chumbly, p. 115 The lead ship of the class, ''Cassard'', was retired in 2019 followed by the retirement of ''Jean Bart'' in 2021. The experience gained during the design and construction of the ''Cassard'' type was used for the design of the . Design The ''Cassard''-class frigate was initially designed to replace the four an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DCNS (company)
Naval Group is a major French industrial group specialized in naval defense design, development and construction. Its headquarters are located in Paris. Heir to the French naval dockyards initiated in 1631 by Cardinal Richelieu and to the Direction des Constructions et Armes Navales (''DCAN''), which became Direction des Constructions Navales (''DCN'') in 1991 and then DCNS in 2007, the company was rebranded ''Naval Group'' in 2017. Its two main shareholders are the French State (62.49%) and Thales Group (35%). Naval Group employs nearly 16,000 people across 18 countries. History Naval Group has a heritage of almost 400 years. Major shipyards were built in France in Brest (1631), Nantes-Indret (1771), Lorient (1778) and, subsequently, in Cherbourg (1813). Others were to follow. As early as 1926, what we know as Naval Group today already had all the facilities now owned by the group in mainland France. The birth of the naval dockyards In 1624, Cardinal Richelieu, who was King ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurocopter Panther
The Eurocopter (now Airbus Helicopters) AS565 Panther is the military version of the Eurocopter AS365 Dauphin medium-weight multi-purpose twin-engine helicopter. The Panther is used for a wide range of military roles, including combat assault, fire support, anti-submarine warfare, anti-surface warfare, search and rescue, and medical evacuation. Development During the 1980s, French aerospace firm Aerospatiale decided to develop a purpose-built military version of their popular Eurocopter AS365 Dauphin. The civil SA365 N variant of the Dauphin was used as the starting point for the project; the new rotorcraft was designed to perform utility, anti-tank, troop-transport, and maritime operations. On 28 February 1984, the military variant prototype, designated as the AS365M and later named Panther, conducted its first flight. A total of three prototypes were built. In May 1986, Aerospatiale formally launched production of the AS365M, at which point the firm anticipated more than 400 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War Frigates Of France
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

CIWS
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Examples of g ...

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The local spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Westland Lynx
The Westland Lynx is a British multi-purpose twin-engined military helicopter designed and built by Westland Helicopters at its factory in Yeovil. Originally intended as a utility craft for both civil and naval usage, military interest led to the development of both battlefield and naval variants. The Lynx went into operational usage in 1977 and was later adopted by the armed forces of over a dozen nations, primarily serving in the battlefield utility, anti-armour, search and rescue and anti-submarine warfare roles. The Lynx is a fully aerobatic helicopter with the ability to perform loops and rolls. In 1986, a specially modified Lynx set the current Fédération Aéronautique Internationale's official airspeed record for helicopters (category excludes compound helicopters) at , which remains unbroken as of January 2022.

Lead Ship
The lead ship, name ship, or class leader is the first of a series or class of ships all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take as many as five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in the class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost-effective than building prototypes, and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to the lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following ship ...

Force D'Action Navale
The ''Force d'action navale'' (FAN, Naval Action Force) is the 9,600-man and about 100-ship force of surface warships of the French Navy. As of 2018, it is commanded by Vice-Amiral d’Escadre Jean-Philippe Rolland. The ships are divided into seven categories: * The aeronaval group, which has the aircraft carrier at its core * The amphibious group, directed by "Projection and Command vessels" (currently ships of the ) * Frigates, which act either as protection for the strategic groups, or alone in monitoring, survey, presence, rescue or deterrence missions * Minesweepers * "Sovereignty" ships, which are deployed overseas and act as presence and prevention forces * Support vessels * Public service ships, hydrographic and oceanographic vessels The aeronaval group The aeronaval group is the main French Navy power projection force. It is also one of the components of the nuclear deterrence forces, since the embarked Super Étendard and Rafale planes have nuclear capabilities. At m ...
