Sonar 2087
Sonar 2087 is a towed array sonar designed and manufactured by Thales Underwater Systems at sites in the UK (Cheadle Heath in Stockport and Templecombe in Somerset) and in France (Brest). Sonar 2087 replaces the older Sonar 2031 in the Royal Navy and equips eight Type 23 frigates. The system is also expected to equip the Royal Navy's future Type 26 Global Combat Ship starting around 2020. It is a Low Frequency Active Sonar (LFAS) and consists of both active and passive sonar arrays. Thales describes the system as "a towed-array that enables Type 23 frigates to hunt the latest submarines at considerable distances and locate them beyond the range at which they ubmarinescan launch an attack." During Exercise Auriga in 2010, HMS ''Sutherland's'' capability equipped with Sonar 2087 was described as "world-beating" by the Sutherland's commanding officer. American, British, Canadian and French warships took part in the exercise, including the French nuclear submarine ''Perle''. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Towed Array Sonar
A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting and tracking faint contacts, such as quiet, low noise-emitting submarine threats, or seismic signals. A towed array offers superior resolution and range compared with hull mounted sonar. It also covers the baffles, the blind spot of hull mounted sonar. However, effective use of the system limits a vessel's speed and care must be taken to protect the cable from damage. History During World War I, a towed sonar array known as the "Electric Eel" was developed by Harvey Hayes, a U.S. Navy physicist. This system is believed to be the first towed sonar array design. It employed two cables, each with a dozen hydrophones attached. The project was discontin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Templecombe
Templecombe is a village in Somerset, England, situated on the A357 road five miles south of Wincanton, east of Yeovil, and west of Salisbury. The village has a population of 1,560. Along with the hamlet of Combe Throop, it forms the parish of Abbas and Templecombe. History Prior to the Norman Conquest Combe was held by Leofwine Godwinson. One part of the village was known as Abbas Combe which was recorded in the ''Domesday Book'' of 1086–7 as ''Cumbe'', when it was held by the church of St Edward, Shaftesbury. The other manor within the parish was held by Godwinson, but after the Norman Conquest, was given to Bishop Odo of Bayeux. It was his descendant Serlo FitzOdo who granted it to the Knights Templar. The parish was part of the Hundred of Horethorne. Templecombe derives its name from ''Combe Templariorum'', after the Knights Templar who established Templecombe Preceptory in the village in 1185. After they were suppressed in 1312 it was granted to the Knights Hosp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brest, France
Brest (; ) is a port city in the Finistère department, Brittany. Located in a sheltered bay not far from the western tip of the peninsula, and the western extremity of metropolitan France, Brest is an important harbour and the second French military port after Toulon. The city is located on the western edge of continental France. With 142,722 inhabitants in a 2007 census, Brest forms Western Brittany's largest metropolitan area (with a population of 300,300 in total), ranking third behind only Nantes and Rennes in the whole of historic Brittany, and the 19th most populous city in France; moreover, Brest provides services to the one million inhabitants of Western Brittany. Although Brest is by far the largest city in Finistère, the ''préfecture'' (regional capital) of the department is the much smaller Quimper. During the Middle Ages, the history of Brest was the history of its castle. Then Richelieu made it a military harbour in 1631. Brest grew around its arsenal unti ...

Sonar 2031
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extrem ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 23 Frigate
The Type 23 frigate or Duke class is a class of frigates built for the United Kingdom's Royal Navy. The ships are named after British Dukes, thus leading to the class being commonly known as the Duke class. The first Type 23, , was commissioned in 1989, and the sixteenth, was commissioned in June 2002. They form the core of the Royal Navy's destroyer and frigate fleet and serve alongside the Type 45 destroyers. They were designed for anti-submarine warfare, but have been used for a range of uses. Twelve Type 23 frigates remain in service with the Royal Navy, with three vessels having been sold to the Chilean Navy, and one being retired in 2021. The Royal Navy's Type 23 frigates will be replaced by the Type 26 Global Combat Ship and the Type 31 frigate. it is anticipated that HMS ''St Albans'' will be the last to retire from the Royal Navy, in 2035. Development When first conceived in the late 1970s, the Type 23 was intended to be a light anti-submarine frigate with a towed ...

Type 26 Frigate
The Type 26 frigate or City-class frigate is a class of frigate being built for the United Kingdom's Royal Navy, with variants also being built for the Australian and Canadian navies. The programme, known as the Global Combat Ship, was launched by the UK Ministry of Defence to partially replace the navy's thirteen Type 23 frigates, and for export. Its primary role is to conduct advanced anti-submarine warfare missions while supporting air defence and general purpose operations. The type is the first naval platform shared between Australia, Canada and the United Kingdom since the Tribal-class destroyer. The programme began in 1998, under what was then known as the Future Surface Combatant (FSC). However, by March 2010, this procurement programme had evolved to become the Global Combat Ship, following the announcement of a four-year, £127 million design contract being awarded to BAE Systems Maritime – Naval Ships. The design passed Main Gate 1 in early 2015, with the Demonstra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Sutherland (F81)
HMS ''Sutherland'' is a Type 23 frigate of the British Royal Navy. She is the thirteenth ship in the ''Duke'' class of frigates and is the third ship to bear the name, more than 200 years since the name was last used. She was launched in 1996 by Lady Christina Walmsley, wife of Sir Robert Walmsley KCB. Before this occasion, Royal Navy ships had always been launched with a bottle of champagne, but Lady Walmsley broke with tradition and used a bottle of Macallan Scotch whisky. Operational history 1997-2000 ''Sutherland'' was deployed to the Falkland Islands in the winter 1998/1999. In 2000, she was part of the task force NTG2000, the first time Royal Navy ships have circumnavigated the globe since 1986. 2001-2010 After berthing in Invergordon, HMS ''Sutherland'' was granted the freedom of the county of Sutherland at a ceremony in Dornoch on 18 September 2004. A subsequent visit to Invergordon in March 2011 was cut short, with "operational commitments" as the given reason. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Submarine Perle (S606)
''Perle'' is a first-generation nuclear attack submarine of the French Navy. The boat is the sixth and last of the ''Rubis'' series. Construction began on the submarine on 27 March 1987. The boat was launched on 22 September 1990 and entered active duty service on 7 July 1993. History The boat was deployed in the Royal Navy Auriga 2010 exercise alongside seven Royal Navy warships and one United States Navy destroyer. 2020 fire On 12 June 2020 at 10:35 a.m., a fire started at bow of ''Perle'', while in drydock for maintenance and repair at the military port of Toulon. The fire was reported as under control at 9:36 PM. Firefighters flooded the rear compartments of the submarine with foam. At least 30 specialist naval fighters and a fireboat were involved. There were no reported injuries in the fire. Since the submarine's 48 megawatt pressurized water nuclear reactor had been removed when it entered the drydock in January 2020, there was no risk of radioactive contaminati ...
