Udav-1 Anti-submarine System
The UDAV-1 system is a Russian ship-borne Anti-submarine weapon system. The weapon fires a number of different types of rockets, which in addition to attacking submarines provide a multi-layer defense against torpedoes and frogmen. The system operates in conjunction with the ship's sonar. The system consists of: *A KT-153 remotely controlled multi-barrel automated rocket launcher with indirect elevation/traverse stabilization; * 111SG depth-charge rockets with HE warhead and impact-time fuse to engage underwater targets; * 111SZ mine-laying rockets with hydro-acoustic proximity fuse for remote mining of a water area to make a barrier for incoming torpedoes; * 111SO decoy rockets to divert homing torpedoes from the surface ship by creating false acoustic target; * fire control devices; * an ammunition loading device; * ground support equipment. Specifications * Number of barrels: 10 * Number of rockets (including reloads): 40-60 * Effective range: 3,000 meters * Effective dept: ...

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] |
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 ...

Frogmen
A frogman is someone who is trained in scuba diving or swimming underwater in a tactical capacity that includes military, and in some European countries, police work. Such personnel are also known by the more formal names of combat diver, combatant diver, or combat swimmer. The word ''frogman'' first arose in the stage name ''The Fearless Frogman'' of Paul Boyton in the 1870s and later was claimed by John Spence, an enlisted member of the U.S. Navy and member of the OSS Maritime Unit, to have been applied to him while he was training in a green waterproof suit. The term ''frogman'' is occasionally used to refer to a civilian scuba diver. Some sport diving clubs include the word ''Frogmen'' in their names. The preferred term by scuba users is ''diver'', but the ''frogman'' epithet persists in informal usage by non-divers, especially in the media and often referring to professional scuba divers, such as in a police diving role. In the U.S. military and intelligence community, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, 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 ...

Proximity Fuse
A proximity fuze (or fuse) is a Fuze (munitions), fuze that detonates an Explosive material, explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonar Decoy
A sonar decoy is a device for decoying sonar. Most are released from submarines to act as a false target. Submarine decoys The first submarine decoys were the German Bold fitted to U-boats of World War II. These were a pellet of calcium hydride in a simple metal container. On contact with sea water, the calcium hydride decomposed to produce a trail of hydrogen gas bubbles that acted as a bubble curtain and reflected ASDIC impulses to produce a false target. The container trapped hydrogen and floated, with a crude spring valve to maintain buoyancy to keep it at a constant depth. Later decoys, such as Sieglinde, were motorised and could deploy their false target away from the host submarine, increasing safety. Torpedo decoys Decoys were also used by surface ships to decoy the developing acoustic torpedoes. These were usually towed behind the host. Example decoys Bubble decoys Reflective bubble targets * Bold * Sieglinde Hammer and explosive decoys These were intended ...

Kuznetsov-class Aircraft Carrier
The ''Kuznetsov''-class aircraft carrying cruiser (Russian: Авиано́сцы ти́па «Кузнецо́в» ''Avianо́stsii Tipa "Kuznetsо́v"''), Soviet designation Project 1143.5, is a class of aircraft carriers operated by the Russian and Chinese navies. Originally designed for the Soviet Navy, the ''Kuznetsov''-class ships use a ski-jump to launch high-performance conventional aircraft in a STOBAR configuration. The design represented a major advance in Soviet fleet aviation over the carriers, which could only launch VSTOL aircraft. The Soviet Union's classification for the class was as a heavy aircraft-carrying cruiser, which permits the ships to transit the Turkish Straits without violating the Montreux Convention. However, the Chinese variants are classified as aircraft carriers. Because of the dissolution of the Soviet Union in 1991, the three ''Kuznetsov''-class ships were built over a protracted construction period of almost four decades. Two ships were ...

Kirov-class Battlecruiser
The ''Kirov'' class, Soviet designation Project 1144 ''Orlan'' (sea eagle), is a class of nuclear-powered guided-missile cruisers of the Soviet Navy and Russian Navy, the largest and heaviest surface combatant warships (i.e. not an aircraft carrier or amphibious assault ship) in operation in the world. Among modern warships, they are second in size only to large aircraft carriers, and of similar size to a World War I-era battleship. The ships are often referred to as battlecruisers by Western defence commentators due to their size and general appearance. The Soviet classification of the ship-type is "heavy nuclear-powered guided-missile cruiser" (russian: тяжёлый атомный ракетный крейсер). The appearance of the ''Kirov'' class played a key role in the recommissioning of the s by the United States Navy in the 1980s. The ''Kirov'' class hull design was also used for the Soviet nuclear-powered command and control ship ''SSV-33 Ural''. History Orig ...

Udaloy-class Destroyer
The ''Udaloy'' class, Soviet designation Project 1155 ''Fregat'' and Russian designation Project 11551 ''Fregat-M'' (russian: Фрегат, 'Fregat' meaning Frigate), are series of anti-submarine guided-missile destroyers built for the Soviet Navy, seven of which are currently in service with the Russian Navy. Twelve ships were built between 1980 and 1991, while the thirteenth ship built to a modified design, known as ''Udaloy II'' class, followed in 1999. They complement the Sovremenny-class destroyers in anti-aircraft and anti-surface warfare operations. The codename Udaloy comes from an archaic Russian adjective ''удалой'', meaning ''daring'' or ''bold''. History The Project 1155 dates to the 1970s when it was concluded that it was too costly to build large-displacement, multi-role combatants. The concept of a specialized surface ship was developed by Soviet designers. Two different types of warships were laid down, which were designed by the Severnoye Design Bureau ...

Naval Weapons Of Russia
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications ( brown-water navy), open-ocean applications (bl ...
