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 are currently building alternative DCL demonstration systems, the first to test was Ultra Electronics Ultra Electro ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

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. History Early activities The company that would eventually become Ultra Electronics was started by wireless specialist Teddy Rosen as Edward E. Rosen & Co. during 1920. The firm was initially focused upon the manufacture of high quality headphones and loudspeakers. During 1923, the company relocated to new premises at Harrow Road, London. In 1925, a new company, known as ''Ultra Electric Ltd.'', was formed; the ''Ultra'' name had been previously used for one of its products, the first commercial moving iron loudspeaker. During 1930, Ultra launched its first all-electric radio receiver. During 1931, the firm introduced its first mains-powered wireless set, known as the ''Ultra Twin Cub''. That same year, Ultra received its first order from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. 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 railroads was largely dependent upon rivers, canals, and other navigable waterways. The latter were crucial in the development of the modern world in Britain, the Low Countries and northern Germany, for they enabled the bulk movement of goods and raw materials without which the Industrial Revolution would not have occurred. Before 1800, war materials were largely moved by river barges or sea vessels and needed a naval defence against enemies. History Mankind has fought battles on the sea for more than 3,000 years.
