Maareech ATDS
Maareech Advanced Torpedo Decoy System (ATDS) is a torpedo detection and countermeasure system used by the Indian Navy. The system offers a complete solution to detect and locate an incoming torpedo and to apply countermeasures to protect naval platform against torpedo attack. It was developed as a joint project of the Naval Physical and Oceanographic Laboratory (NPOL), Kochi and the Naval Science and Technological Laboratory (NSTL), Visakhapatnam. Description It is an anti-torpedo system with towed and expendable decoys. The system is capable of detecting, confusing, diverting and decoying the incoming torpedoes. The decoy helps in exhausting the energy of the torpedo by running the latter through long and ineffective course and prevents them from homing in to the targeted platform with its advanced countermeasures capabilities. Mareech systems is being deployed on all current and future frontline warships of Indian Navy ships. The underwater arrays for Maareech are being ...

Close-in Weapon System
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 ...

AK-630
The AK-630 is a Soviet Union, Soviet and Russian fully automatic naval, rotary cannon, close-in weapon system. The "630" designation refers to the weapon's six gun barrels and their 30 mm caliber. The system is mounted in an enclosed automatic turret and directed by MR-123 fire-control radar and television detection and tracking. The weapon's primary purpose is defense against aircraft and helicopters. As one of the tried-and-true CIWS systems available, effectiveness against anti-ship missiles has been demonstrated over the years in exercises, making it the staple anti-air weapon of most Soviet naval vessels. The AK-630 can also be employed against ships and other small craft, coastal targets, and floating mines. Once operational, the system was rapidly adopted and installed in every new Soviet warship (from mine-hunters to aircraft carriers) with up to eight units on larger vessels; hundreds have been produced in total. History It is reported that Gun and Shell Factory makes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Artillery
Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for more specialized roles in surface warfare such as naval gunfire support (NGFS) and anti-aircraft warfare (AAW) engagements. The term generally refers to powder-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines. Origins The idea of ship-borne artillery dates back to the classical era. Julius Caesar wrote about the Roman navy's usage of ship-borne catapults against Celtic Britons ashore in his ''Commentarii de Bello Gallico''. The dromons of the Byzantine Empire carried catapults and Greek fire. From the Middle Ages onwards, warships began to carry cannons of various calibres. In the Battle of Tangdao in 1161, the Southern Song general Li Bao used huopao (a type of gunpowder weapons, possibly cannons) and fire arro ...

Anti-submarine Weapon
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RBU-6000
The RBU-6000 Smerch-2 (Реактивно-Бомбовая Установка, ''Reaktivno-Bombovaja Ustanovka''; rocket-bomb installation & Смерч; waterspout) is a 213 mm caliber Soviet anti-submarine rocket launcher. The system entered service in 1960–1961 and is fitted to a wide range of Russian surface vessels. It consists of a horseshoe-shaped arrangement of twelve launch barrels, that are remotely directed by the Burya fire control system (that can also control the shorter-ranged RBU-1000). It fires RGB-60 rockets, which carry unguided depth charges. The rockets are normally fired in salvos of 1, 2, 4, 8 or 12 rounds. Reloading is automatic, with individual rounds being fed into the launcher by the 60UP loading system from a below-deck magazine. Typical magazine capacity is either 72 or 96 rounds per launcher. It can also be used for shore bombardment. The system is an upgrade of the RBU-6000 system, firing the 90R rocket, which releases a 90SG depth charge t ...

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although Torpedo#Classes and diameters, torpedoes of other classes and diameters have been used. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the ...

Anti-ship Missile
An anti-ship missile (AShM or ASM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea-skimming variety, and many use a combination of inertial guidance and active radar homing. A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. Many anti-ship missiles can be launched from a variety of weapons systems including surface warships (also referred to as ship-to-ship missiles), submarines, bombers, fighter planes, patrol planes, helicopters, shore batteries, land vehicles, and, conceivably, even infantrymen firing shoulder-launched missiles. The term surface-to-surface missile (SSM) is used when appropriate. The longer-range anti-ship missiles are often called anti-ship cruise missiles. Several countries are also developing anti-ship ballistic missiles. Etymology Both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
