Black Scorpion Torpedo
Black Scorpion is a miniature torpedo developed by Leonardo S.p.A. Description The Black Scorpion is a miniature active-sonar homing torpedo developed from the A200 LCAW, which in turn was originally developed to assist in the classification of targets. In order to deal with a potentially hostile submarine target, either a depth charge or a torpedo would be launched at it, either to kill it or cause it to flee, thus confirming it as a hostile submarine. With the obsolescence of conventional depth charges and the high cost of homing torpedoes, an intermediate solution was developed. The Black Scorpion is a full-featured acoustic homing torpedo with greater speed and endurance than its predecessor. Shallow-water performance has been enhanced, with normal operational depth stated as ranging from 30 to 200 meters when deployed from an aircraft, and a speed of at least 15 knots. The weapon is capable of launch from surface, underwater, and aerial launch tubes. The air-dropped version ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marina Militare
The Italian Navy (; abbreviated as MM) is one of the four branches of Italian Armed Forces and was formed in 1946 from what remained of the '' Regia Marina'' (Royal Navy) after World War II. , the Italian Navy had a strength of 30,923 active personnel, with approximately 184 vessels in service, including minor auxiliary vessels. It is considered a multiregional and a blue-water navy. History Before and during World War II The '' Regia Marina'' was formed on 17 March 1861, after the proclamation of the Kingdom of Italy. The Italian Navy assumed its present name after the Italian monarchy was abolished following a popular referendum held on 2 June 1946. After World War II At the end of its five years involvement in World War II, Italy was a devastated nation. After the end of hostilities, the ''Regia Marina'' – which at the beginning of the war was the fourth largest navy in the world, with a mix of modernised and new battleships – started a long and complex rebuilding pr ...

Midget Submarine
A midget submarine is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships. Most early submarines would now be considered midget submarines, such as the United States Navy's and the British Royal Navy's (both named for the same John Philip Holland, designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-class submarine, X-craft and the unsuccessful Welman submarine, were specifically designe ...

Torpedoes Of Italy
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, 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 ships wi ...

Black Shark Torpedo
The Black Shark is a heavyweight torpedo developed by WASS of Italy. Development Whitehead Alenia Sistemi Subacquei Italy developed the Black Shark torpedo as an evolution of the A184, with more advanced electronic counter-countermeasures (ECCM) abilities and sonar. The advancements in electric motor design and battery allowed an increase in both range and speed. Features The Black Shark torpedo offers fiberoptic wire for increased bandwidth and signal processing ability compared to copper wire-guided torpedo types. The sonar capability include non-doppler shifted target discrimination and multi-frequency capability that features advanced spatial and angular analysis abilities. The design goal for the torpedo was 300% improvement of passive acquisition and 200% active acquisition with its sonar system. The brushless motor design coupled with the aluminum-silver oxide (Al-AgO) battery gives the system a top speed , and a range of , performance envelope. Like all other battery ...

Sonar Decoy
A sonar decoy is a device for decoying sonar. One may be released from a submarine or a surface vessel. A decoy acts as false targets for human operators and/or sonar-homing weapons such as acoustic torpedoes. Many count as a type of torpedo defence. Submarine decoys The first submarine decoys were the German Bold (decoy), 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 (decoy), Sieglinde, were motorised and could deploy their false target away from the host submarine, increasing safety. Surface ship decoys Decoys were also used by surface ships to decoy the developing acoustic to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frogmen
A frogman is someone who is trained in scuba diving or swimming underwater. The term often applies more to professional rather than recreational divers, especially those working 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, such as in a police diving role. In the United Kingdom, police divers have often been called "police frogmen". Some countries' tactical diver organizations include a translation of the word ''frogman'' in their official names, e.g., Denmark ...

Human Torpedo
Human torpedoes or manned torpedoes are a type of diver propulsion vehicle on which the diver rides, generally in a seated position behind a fairing. They were used as secret naval weapons in World War II. The basic concept is still in use. The name was commonly used to refer to the weapons that Italy, and later (with a larger version) Britain, deployed in the Mediterranean and used to attack ships in enemy harbours. The human torpedo concept has occasionally been used by recreational divers, although this use is closer to midget submarines. More broadly, the term ''human torpedo'' was used in the past to refer to vehicles which are now referred to as wet submarines and diver propulsion vehicles. Midget submarines which are employed to directly support frogman operations, whether possessing airlocks or not, if used as underwater tugs to transport equipment and frogmen clinging to their exterior, also blur the line between the human torpedo and more sophisticated underwat ...

Diver Propulsion Vehicle
A diver propulsion vehicle (DPV), also known as an underwater propulsion vehicle, sea scooter, underwater scooter, or swimmer delivery vehicle (SDV) by armed forces, is an item of diving equipment used by scuba divers to increase range underwater. Range is restricted by the amount of breathing gas that can be carried, the rate at which that breathing gas is consumed, and the battery power of the DPV. Time limits imposed on the diver by decompression requirements may also limit safe range in practice. DPVs have recreational, scientific and military applications. DPVs include a range of configurations from small, easily portable scooter units with a small range and low speed, to faired or enclosed units capable of carrying several divers longer distances at higher speeds. The earliest recorded DPVs were used for military purposes during World War II and were based on torpedo technology and components. Structure A DPV usually consists of a pressure-resistant watertight casing c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sonobuoy
A sonobuoy (a portmanteau of sonar and buoy) is a small expendable sonar buoy dropped from aircraft or ships for anti-submarine warfare or underwater acoustic research. Sonobuoys are typically around in diameter and long. When floating on the water, sonobuoys have both a radio transmitter above the surface and hydrophone sensors underwater. Sonobuoys are mission-critical platforms for enhancing Undersea Domain Awareness (UDA), providing an effective means to detect, locate, and track submarines and other underwater threats. Playing a key role in anti-submarine warfare (ASW) and other naval operations, they support in maintaining naval security and in protecting naval carrier strike groups. Theory of operation Sonobuoys are ejected from aircraft in canisters and deploy upon water impact. An inflatable surface float with a radio transmitter remains on the surface for communication with the aircraft, while one or more hydrophone sensors and stabilizing equipment descend be ...

Cyprus Navy
The Cyprus Naval Command (, ) (also known as the Cyprus Navy or Cypriot Navy) is the armed sea wing of the Cyprus National Guard. The Cypriot Navy has the primary mission of defending the maritime borders of the Republic of Cyprus, but is currently unable to access the waters around Northern Cyprus, which have been controlled by the Turkish Navy since the 1974 Turkish invasion of Cyprus. This force does not possess any capital ships or other major warships, but is equipped with patrol boats, landing craft, surface-to-surface missile systems and integrated radar systems, as well as SEALs-type naval underwater demolitions units. History Combat actions of 1964 On 6 August 1964, Cyprus National Guard forces commenced combat action against the Turkish Cypriot enclave of Kokkina, in the north-west of Cyprus. This operation was regarded by both Cyprus and Greece as a necessary interdiction against a threat by Turkish Cypriot militia, who were using Kokkina as a beachhead by which to ...
