SSTD
The United Kingdom Surface Ship Torpedo Defence (SSTD) system entered into service with the Royal Navy in 2004. The system is produced by Ultra ElectronicsSSTD Datasheet at the Ultra Electronics website and is known as S2170 or Sonar 2170 by the and as Sea Sentor in the export market. The system consists of * an acoustic passive towed array * a towed acoustic countermeasure (flexible) * a single-drum winch * a processing cabinet * 2 display consoles * 2 expendable acoustic device launchers (1 port, 1 starboard) * 16 expendable acoustic devices (8 in each launcher) The system is a footprint compatible replacement for the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/SLQ-25 Nixie
The AN/SLQ-25 Nixie and its variants are towed torpedo decoys used on US and allied warships. It consists of a towed decoy device (TB-14A) and a shipboard signal generator. The Nixie is capable of defeating wake-homing, acoustic-homing, and wire-guided torpedoes. The decoy emits signals to draw a torpedo away from its intended target. The Nixie attempts to defeat a torpedo's passive sonar by emitting simulated ship noise—such as propeller and engine noise—or defeat a torpedo's active sonar by amplifying and returning its pings. Typically, larger ships may have two Nixie systems mounted at the stern of the ship to allow operation singularly or in pairs while smaller ships may have only one system. In accordance with the Joint Electronics Type Designation System (JETDS), the "''AN/SLQ-25''" designation represents the 25th design of an Army-Navy electronic device for waterborne countermeasures special equipment. The JETDS system also now is used to name all Department of D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DCL Technology Demonstrator Programme
The US DCL (Detection Classification and Localisation) demonstrator program is aimed at proving that an active torpedo detection system is able to resolve a salvo of torpedoes with sufficient time and accuracy that an anti-torpedo torpedo may be fired back to hit and destroy the threat. Overview The DCL systems consist of an active source emitter which sends high-frequency pings into the water. Reflections from in-water objects are received by a towed array tuned to those frequencies. By processing the reflections it is possible to determine whether objects are torpedoes, or non-threat objects. The system is also combined with a passive acoustic towed array specifically designed for torpedo detection. The passive acoustic array is able to analyse the structured sound emanating from a torpedo and thereby classify the weapon type and mode of operation. Two teams were building alternative DCL demonstration systems, the first to test was Ultra Electronics Ultra Electronics Holdin ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. 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 superior ...

Ultra Electronics
Ultra Electronics Holdings is a British defence and security company. It was listed on the London Stock Exchange and was a constituent of the FTSE 250 Index until it was acquired by Cobham, which is itself owned by Advent International. The company was originally founded as ''Edward E. Rosen & Co.'', a manufacturer of headphones and loudspeakers, in 1920. In 1925, a new company, known as ''Ultra Electric Ltd.'', was established. During 1930, the firm launched its first all-electric radio receiver; it produced numerous domestic radio receivers around this time. Ultra diversified into aviation during the Second World War, building fuselage elements and engine components. Relaunching itself into the civilian markets following the conflict, Ultra started producing television sets in 1953. In 1961, Ultra's consumer electronics interests became part of Thorn Electrical Industries. During 1977, Ultra Electronics was bought by the Dowty Group and regained its independence via a man ...

Close-in Weapon Systems
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 ...

Naval Warfare
Naval warfare is combat in and on the sea, the ocean, or any other battlespace involving a major body of water such as a large lake or wide river. The Military, armed forces branch designated for naval warfare is a navy. Naval operations can be broadly divided into riverine/littoral applications (brown-water navy), open-ocean applications (blue-water navy), between riverine/littoral and open-ocean applications (green-water navy), although these distinctions are more about strategic scope than tactical or operational division. The strategic offensive purpose of naval warfare is Power projection, projection of force by water, and its strategic defensive purpose is to challenge the similar projection of force by enemies. History Mankind has fought battles on the sea for more than 3,000 years. Even in the interior of large landmasses, transportation before the advent of extensive rail transport, railways was largely dependent upon rivers, lakes, canals, and other navigable waterways ...
