Tourville-class frigate

The F67 type, also known as the Tourville class was a class of large high-sea (blue water) destroyers 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.

The Crotale missile launcher

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 Tourvilles were typically placed in the destroyer category of warship and carry destroyer pennant numbers. Similar in many regards to the unmodified Spruance-class destroyers, they carried a similar combination of sensors, naval guns, anti-ship and anti-submarine weapons, aircraft and surface-to-air missiles. Additionally, they were well-regarded for their seakeeping, serving much of their careers in the Atlantic rather than with France's Mediterranean fleet.[1]

Ships

The three ships of the class, D612 De Grasse, D611 Duguay-Trouin and D610 Tourville, are named major figures from French naval history. De Grasse and Tourville were French admirals and Duguay-Trouin coming to fame as a privateer.

The three ships of the class were all constructed by Arsenal de Lorient.

French ship De Grasse

Three ships of the French Navy have borne the name De Grasse in honour of François Joseph Paul de Grasse:

De Grasse (1939), a requisitioned steamer

De Grasse (C610), an anti-aircraft cruiser (1946–1974)

De Grasse (D 612), a Tourville-class frigate, presently in service

French ship Duguay-Trouin

Twelve vessels of the French Navy have been named Duguay-Trouin in honour of René Duguay-Trouin.

Duguay-Trouin (1781–1793), a 74-gun ship of the line

Duguay Trouin (1793–1794) was the East Indiaman Princess Royal that the French captured in the Indian Ocean on 27 September 1793 and took into service as an ad hoc 36-gun frigate that they named Duguay Trouin; the British recaptured her on 5 May 1794.

Duguay-Trouin (1794–1795/6) was a tartane that the French Navy requisitioned in 1794 to serve as an aviso. The Navy renamed her Dangereuse in 1795 or 1796. The British Royal Navy captured her in 1799 and took her into service as HMS Dangereuse, but then sold her in 1801.

Duguay-Trouin (1795–1805), a 74-gun ship of the line; the Royal Navy captured her at the Battle of Trafalgar. The British renamed her HMS Implacable, and she was the oldest ship of the line after HMS Victory when she was scuttled in 1948

Duguay-Trouin (1813–1824), a 74-gun ship of the line

Duguay-Trouin (1854–1872), a 90-gun ship of the line

Duguay-Trouin (1873–1899), an ironclad cruiser

Duguay-Trouin (1900–1914), a training cruiser transformed into a hospital. The soldier-poet Rupert Brooke died aboard en route to the Dardanelles on 23 April 1915 at Trebuki Bay, Skyros

Duguay-Trouin (1923–1952), a light cruiser, lead ship of her class, which served with the Free French Forces

Duguay-Trouin, a Tourville-class frigate, decommissioned in 1999

A Barracuda-class submarine is scheduled to bear the nameSee also

Guided missile destroyer

A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system.

In addition to the guns, a guided-missile destroyer is usually equipped with two large missile magazines, usually in vertical-launch cells. Some guided-missile destroyers contain powerful radar systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true of navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap.

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 slewed to the correct bearing, whereupon it is fired at a fixed elevation of +15°. Two solid booster rockets accelerate it to 830 km/h within 4 seconds before falling away. The unpowered glider continues at an altitude of 100 meters, altering course in mid-flight under radio control of the launch platform. Effective range was 13 km. 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 800 m of the submarine's location. The L4 torpedo had a speed of 30 kt over a range of 5 km.

The Malafon was a large weapon, with each missile weighing 1,330 kg. As a result, it was only employed on larger vessels. It was typically used for medium- and long-range submarine targets, though it could have been used against surface ships.

The system was never used at war. It was declared obsolete in 1997. It was replaced by Westland Lynx helicopters using Mark 46 torpedoes.

Operation Atalanta

Operation Atalanta, formally European Union Naval Force (EU NAVFOR) Somalia, is a current counter-piracy military operation at sea off the Horn of Africa and in the Western Indian Ocean, that is the first naval operation conducted by the European Union (EU). The operational headquarters is currently located at the Spanish Operation Headquarters (ESOHQ) at Naval Station Rota (NAVSTA Rota) in Spain as a result of the impending British withdrawal from the EU.The mission launched in December 2008 with a focus on protecting Somalia-bound vessels and shipments belonging to the WFP and AMISOM, as well as select other vulnerable shipments. In addition, Operation Atalanta monitors fishing activity on the regional seaboard. In 2012, the scope of the mission expanded to include Somali coastal territories and internal waters so as to co-ordinate counter-piracy operations with Somalia's Transitional Federal Government (TFG) and regional administrations. On 16 July 2012, the EU also mandated the EUCAP Nestor mission to build up the maritime capacity of regional navies.It is part of a larger global action by the EU to prevent and combat acts of piracy in the Indian Ocean, and it is the first EU naval operation to be launched. It cooperates with the multinational Combined Task Force 151 of the US-led Combined Maritime Forces (CMF) and NATO's anti-piracy Operation Ocean Shield.

Steam turbine

A steam turbine is a device 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 Sir Charles Parsons in 1884.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 is particularly suited to be used to drive an electrical generator—about 85% of all electricity generation in the United States in the year 2014 was by use of steam turbines.
