Sonar 2076 is a submarine sonar detection system designed by Thales for the Royal Navy.
The system comprises an integrated suite of active and passive sonar systems including bow, fin, flank and towed arrays. [1] Known components include:
Support systems include command consoles, upgraded radio communications, upgraded signature reduction, and new flexi couplings to reduce self noise. Sonar 2076 is designed to be fitted into both the new Astute-class submarine and the existing Trafalgar-class submarine, allowing the Royal Navy's entire submarine fleet to have a common sonar system. BAE Systems, which is responsible for building the Astute-class submarines and integrating the Type 2076 Sonar, claims that the 2076 represents a "step change" over previous sonars and is the world's most advanced and effective sonar system. [2] It is said to have 13,000 hydrophones, many times the number fitted in previous Royal Navy systems [3] and more than any other submarine sonar in the world. [4] A key development is the use of high performance and easily upgradeable commercial off-the-shelf (COTS) processing systems, allowing the introduction of much more sophisticated algorithms compared to earlier sonars. [5] The processing power of the system is said to be equivalent to 60,000 home PCs. [3]
Swiftsure and Trafalgar Update manager, Captain Ian Hughes said, "A good analogy for the performance of Sonar 2076 is that if the submarine was in Winchester it would be able to track a double decker bus going round Trafalgar Square" (a distance of about 60 miles). [6]
Sonar is a technique that uses sound propagation to navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels.
The Trafalgar class is a class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy, and the successor to the Swiftsure class. Like the majority of Royal Navy nuclear submarines, all seven boats were constructed at Barrow-in-Furness shipyard, Cumbria. With only one boat remaining active and in commission and six retired from the seven originally in service, the class makes up part of the Royal Navy's nuclear-powered ‘hunter-killer’ submarine force. The Trafalgar class has nearly been replaced by the larger and more capable Astute class, of which five are commissioned.
The Vanguard class is a class of nuclear-powered ballistic missile submarines (SSBNs) in service with the Royal Navy. The class was introduced in 1994 as part of the Trident nuclear programme, and comprises four vessels: Vanguard, Victorious, Vigilant and Vengeance, built between 1986 and 1999 at Barrow-in-Furness by Vickers Shipbuilding and Engineering, now owned by BAE Systems. All four boats are based at HM Naval Base Clyde , 40 km (25 mi) west of Glasgow, Scotland.
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, HMS Norfolk, was commissioned in 1989, and the sixteenth, HMS St Albans 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. Ten 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, and two being retired in 2023.
The Upholder/Victoria-class submarines, also known as the Type 2400, are the class of the diesel-electric submarines built in the United Kingdom in the 1980s to supplement the nuclear submarines in the Submarine Service of the British Royal Navy.
The Astute class is the latest class of nuclear-powered fleet submarines (SSNs) in service with the Royal Navy. The boats are being constructed by BAE Systems Submarines at Barrow-in-Furness. Seven boats will be constructed: the first of class, Astute, was launched by Camilla, Duchess of Cornwall, in 2007, commissioned in 2010, and declared fully operational in May 2014. The Astute class is the replacement for the Trafalgar-class fleet submarines in Royal Navy service.
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet and Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and missile submarines. Some attack subs are also armed with cruise missiles, increasing the scope of their potential missions to include land targets.
HMS Talent is the sixth of seven Trafalgar-class nuclear submarines operated by the Royal Navy from 1990 until 2022. and was built at Barrow-in-Furness.
The 46 Knox-class frigates were the largest, last, and most numerous of the US Navy's second-generation anti-submarine warfare (ASW) escorts. Originally laid down as ocean escorts, they were all redesignated as frigates on 30 June 1975, in the 1975 ship reclassification plan and their hull designation changed from 'DE' to 'FF'. The Knox class was the Navy's last destroyer-type design with a steam turbine powerplant.
HMS Cleopatra (F28) was a Leander-class frigate of the Royal Navy (RN). Cleopatra was built at HMNB Devonport. She was launched on 21 March 1964, commissioned on 1 March 1966 and decommissioned on 31 January 1992.
HMS Matapan (D43) was a later or 1943 Battle-class fleet destroyer of the Royal Navy (RN). She was named after the Battle of Cape Matapan between the Royal Navy and the Regia Marina, which ended in a decisive victory for the RN force, resulting in the destruction of three cruisers and two destroyers of the Italian Navy and was a heavy blow to the Italians. So far, she has been the only ship of the Royal Navy to bear that name.
Sonar 2087 is a towed array sonar designed and manufactured by Thales Underwater Systems at sites in the UK 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 equipped on the Royal Navy's Type 26 frigate fleet currently in production. S2087 is also used on Chilean Type 23 frigates transferred from the Royal Navy, while CAPTAS-4 is used on French and Italian FREMM frigates, Spanish F110 frigates, and the US Navy FFG-64 Constellation-class frigates.
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.
The Type 039 submarine is a class of diesel-electric submarines of the People's Liberation Army Navy. The class is the first diesel-electric submarine to be fully developed within China and also the first Chinese diesel-electric submarine to use the teardrop hull shape.
The Type 039A submarine is a class of diesel-electric submarine in China's People's Liberation Army Navy. It is China's first AIP powered submarine and presumed to be one of the quietest diesel-electric submarine classes in service. This class is the successor of the Type 039 submarine. The official Chinese designation is 039A as the ship is based on the 039 class, but as the 039A has very little resemblance to the 039 it is commonly referred to as the Type 041. The class is designed to replace the aging Type 033 and the older Type 035 submarines that previously formed the backbone of the conventional submarine force.
The People's Liberation Army Navy (PLAN) is the naval branch of the People's Liberation Army (PLA), the armed forces of the People's Republic of China. The PLAN force consists of approximately 250,000 men and over a hundred major combat vessels, organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet.
SMCS, the Submarine Command System, was first created for the Royal Navy of the United Kingdom's Vanguard-class submarines as a tactical information system and a torpedo weapon control system. Versions have now also been installed on all active Royal Navy submarine classes.
The AN/UQQ-2 Surveillance Towed Array Sensor System (SURTASS), colloquially referred to as the ship's "Tail", is a towed array sonar system of the United States Navy.
The Heroine class are a variant of the Type 209 diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft (HDW) of Germany, currently in service with the South African Navy. The class is composed of three vessels.
The KSS-III or Dosan Ahn Changho-class is a series of diesel-electric attack submarines currently being built for the Republic of Korea Navy (ROKN), jointly by Hanwha Ocean and HD Hyundai Heavy Industries (HHI). The KSS-III is the final phase of the Korean Attack Submarine program, a three-phased program to build 27 attack submarines for the ROKN, between 1994–2029.
