Tourville-class Frigate
The F67 type, also known as the ''Tourville'' class was a class of large high-sea (blue water) Frigates of the French Navy specialised in anti-submarine warfare. They had anti-air and anti-surface capabilities. Between 1994 and 1996, ''Tourville'' and ''De Grasse'' were refitted with the modern SLASM anti-submarine system, and active Very Low Frequency (VLF) sonar. Design The ships are an enlarged version of the frigate ''Aconit''. They have two shaft steam turbine machinery and a double hangar for two Lynx WG13 helicopters. They were the first ships fitted with the marine version of the Crotale surface-to-air missile system. A Malafon anti-submarine missile system was fitted when the ships were built but this was removed during refits in the late 1980s. Optimized for anti-submarine warfare, and carrying towed as well as hull-mounted sonar arrays, the ''Tourville''s were typically placed in the destroyer category of warship and carry destroyer pennant numbers.

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Frigate Classes
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), armoured frigates were developed as powerful ironclad warships, the term frigate was used because of their single gun deck. Later developments in ironclad ships rendered the frigate designation obsolete and the term fell out of favour. During the Second World War the name 'frigate' was reintroduced to des ...

Destroyer Classes
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lorient
Lorient (; ) is a town ('' commune'') and seaport in the Morbihan department of Brittany in western France. History Prehistory and classical antiquity Beginning around 3000 BC, settlements in the area of Lorient are attested by the presence of megalithic architecture. Ruins of Roman roads (linking Vannes to Quimper and Port-Louis to Carhaix) confirm Gallo-Roman presence. Founding In 1664, Jean-Baptiste Colbert founded the French East Indies Company. In June 1666, an ordinance of Louis XIV granted lands of Port-Louis to the company, along with Faouédic on the other side of the roadstead. One of its directors, Denis Langlois, bought lands at the confluence of the Scorff and the Blavet rivers, and built slipways. At first, it only served as a subsidiary of Port-Louis, where offices and warehouses were located. The following years, the operation was almost abandoned, but in 1675, during the Franco-Dutch War, the French East Indies Company scrapped its base in Le H ...

René Duguay-Trouin
René Trouin, Sieur du Gué, also known as René Duguay-Trouin, (10 June 1673 – 1736) was a French naval officer, nobleman, slave trader, and privateer best known for his career during the War of the Spanish Succession. He had a brilliant privateering and naval career and eventually became "Lieutenant-General of the Naval Armies of the King" (i.e. Vice admiral) (French:''Lieutenant-Général des armées navales du roi''), and a Commander in the Order of Saint-Louis. Ten ships of the French Navy have since been named in his honour. Early life Duguay-Trouin was born in Saint-Malo, Brittany on 10 June 1673. His family were ship-owners, operating a shipping business out of Saint-Malo, a port favoured by French corsairs. At the age of 16, Duguay-Trouin first went to sea as a sailor on board the French privateer ''Trinité'' under the command of a Captain Legoux. The privateer subsequently captured two enemy merchant ships, the ''François Samuel'' and ''Seven Stars of Sc ...

Anne Hilarion De Tourville
Anne-Hilarion de Costentin, Comte de Tourville (24 November 1642, Paris – 23 May 1701) was a French naval commander who served under King Louis XIV. He was made Marshal of France in 1693. Tourville is widely considered as one of the most celebrated admirals in French naval history and is usually counted as one of the greatest naval technicians of his time . Military career At age 17, as a Knight of Malta, he fought his first naval battle on a frigate of the Order of Malta. At 25, he joined the French Royal Navy and began an active career, fighting the 1673 campaign of the Franco-Dutch War on the '' Sans-Pareil'', at the Battle of Agosta where he was in command of the ''Syrene'', and later in command of the ''Sceptre''. He served under Abraham Duquesne during the campaigns of 1676, and became a commander in 1690 during the War of the Grand Alliance. He flew his personal flag on the '' Soleil-Royal'', where it would stay until the battle of La Hougue in 1692. At the Battle o ...

Seakeeping
Seakeeping ability or seaworthiness is a measure of how well-suited a watercraft is to conditions when underway. A ship or boat which has good seakeeping ability is said to be very seaworthy and is able to operate effectively even in high sea states. Measure In 1976, St. Denis suggested four principal terms needed to describe a seakeeping performance. These are: *Mission: what the ship is intended to accomplish. The role of the ship while at sea. *Environment: the conditions under which the ship is operating. This can be described as sea state, wind speed, geographic region or some combination thereof. *Ship responses: the response of the ship to the environmental conditions. The responses are a function of the environment and the vessel characteristics. *Seakeeping performance criteria: the established limits for the ship's responses. These are based on the ship motions and the accelerations experienced, and include comfort criteria such as noise, vibration and sea sickness, perf ...

Malafon
Malafon (MArine LAtécoère FONds) was a French ship-launched anti-submarine missile system. Developed in the 1950s and 1960s, the weapon was intended to take advantage of the greater detection ranges possible with towed sonar arrays. The missile entered service in 1966 and was manufactured by Groupe Latécoère The weapon is essentially a glider-delivered version of the L4 torpedo. The launcher is a circular mount, which allows the weapon to be rotated to the correct bearing, then fired at a fixed elevation of +15°. Two solid booster rockets accelerate it to within 4 seconds before falling away. The unpowered glider continues at an altitude of , altering course in mid-flight under radio control of the launch platform. Effective range was . As it reaches the target, the glider drops the torpedo, which splashes into the sea and commences a circular search pattern. The range of the Malafon meant that it was expected to hit the water within of the submarine's location. The L4 to ...

Crotale (missile)
The Crotale (English: "Rattlesnake") is a French, all-weather, short-range surface-to-air missile system developed to intercept airborne ranged weapons and aircraft, from cruise or anti-ship missiles to helicopters, UAVs or low-flying high-performance fighter aircraft. It was developed by Thomson CSF Matra (now Thales Group) and consists of a mobile land-based variant as well as various naval ones. Development Originally the Crotale R440 system was developed by Rockwell International and Thomson-Houston (and Mistral) in France for South Africa, where it was named Cactus. However, the achievements of the system impressed the French Armed Forces, who purchased the system both for the air force and for the navy. The firing system includes the main sensors of the ship, the firing system of the turret, and a central coordination system. The turret holds eight missiles ready for launch in watertight containers. The magazine behind the turret holds 18 missiles. The French army firs ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
