Anti-submarine Mortar
Anti-submarine mortars are artillery pieces deployed on ships for the purpose of sinking submarines by a direct hit with a small explosive charge. They are often larger versions of the mortar used by infantry and fire a projectile in relatively the same manner. They were created during World War II as a development of the depth charge and work on the same principle. Beginnings Anti-submarine warfare did not become an issue of great concern until World War I, when Germany used submarines in an attempt to strangle British shipping in the Atlantic Ocean and elsewhere. The earliest way to counter a submarine was in the form of depth charges, which were large canisters filled with explosives, rolled off the back of a ship and detonated by a hydrostatic fuse. Depth charges served well throughout World War I but were not without flaws. A ship had to pass directly over a submarine to score an effective hit, because of this depth charges were dropped in lines instead of more effective cl ...

Submarine
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion o ...

Mousetrap (weapon)
Mousetrap (ASW Marks 20 and 22) was an anti-submarine rocket used mainly during World War II by the United States Navy and Coast Guard. Its development began in 1941 as a replacement for Hedgehog, a British-made projector, which was the first forward-throwing ASW weapon. Those, however, were spigot-launched, placing considerable strain on the launching vessel's deck, whereas Mousetrap was rocket-propelled. As a result, Mousetrap's four or eight rails for rockets saved weight and were easier to install. The rockets weighed each, with a Torpex warhead and contact pistol A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any ve ..., exactly like Hedgehog. By the end of the war, over 100 Mousetrap Mark 22s were mounted in U.S. Navy ships, including three each on 12 destroyers, and subma ...

Anti-submarine Warfare
Anti-submarine warfare (ASW, or in older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades. Successful ASW operations typically involved a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RPK-1 Vikhr
The RPK-1 Vikhr NATO reporting name SUW-N-1 (russian: РПК-1 «Вихрь» - meaning Whirlwind) was a Soviet nuclear anti submarine missile system. FRAS-1 was the NATO code for the missile round itself. The development of the missile was ordered in 1960 in order to combat the new American nuclear submarines. The requirement was for an all weather weapon capable of reaching out to 20 km at speed. The first test was in 1964 and the system was installed on the Moskva class helicopter cruisers in 1967. The system was also installed on the Kiev class aircraft carriers. The systems were decommissioned in the 1990s. Launchers There were two models of launcher: * MS-18 used in the Moskva class - a two arm launcher with a rotary magazine holding 8 missiles * MS-32 used in the Kiev class - a two arm launcher with two rotary magazines holding 16 missiles A prototype launcher was mounted on the Petya class frigate SKR-1 for testing in 1964 Missile The missile was a two-stage ...

RBU-6000
The RBU-6000 Smerch-2 (Реактивно-Бомбовая Установка, ''Reaktivno-Bombovaja Ustanovka''; reaction engine-bomb installation & Смерч; waterspout) is a 213 mm caliber Soviet anti-submarine rocket launcher. It is similar in principle to the Royal Navy Hedgehog system used during the Second World War. 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 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 upgra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swedish Navy
The Swedish Navy ( sv, Svenska marinen) is the naval branch of the Swedish Armed Forces. It is composed of surface and submarine naval units – the Fleet () – as well as marine units, the Amphibious Corps (). In Swedish, vessels of the Swedish Navy are given the prefix "HMS", short for (His/Her Majesty's Ship). In English, this is sometimes changed to "HSwMS" ("His Swedish Majesty's Ship") to differentiate Swedish vessels from those of the British Royal Navy. Founded under King Gustav I in 1522, the Swedish navy is one of the oldest continuously serving navies in the world, celebrating its 500th anniversary in 2022. History Early Swedish kings ( 9th–14th centuries) organised a Swedish Navy along the coastline through . This involved combined rowing and sailing ships (without artillery). This system became obsolete with the development of society and changes in military technology. No later than in the 14th century, the duty to serve in was replaced by a t ...

Bofors 375mm Anti Submarine Rockets
The 375mm ASW rocket family is an ahead-throwing anti-submarine warfare (ASW) rocket launcher system developed by Bofors. The system has three types of launcher with either two, four or six barrels, and entered service in the 1950s. Sweden used the four-barreled system on the and s. France built the four-barrelled system under licence then developed the six-barrel system and used it on many classes of warship including and destroyers and A 69-class avisos (corvettes). The Netherlands used it in the s. It was also was used by Royal Malaysian Navy on the s before they removed it from the ships. Indonesia use it on its three s and Brazil on six s, all of which are still in service. The rocket system is also being used by the Turkish Burak-class corvette's which are all ex- ''D'Estienne d'Orves''-class A69 type aviso corvettes, mainly designed for coastal anti-submarine defense and ocean escort missions.

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. 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 superiority globally. Owing to this historical prominence, it is common, even among non-Britons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limbo (weapon)
Limbo, or Anti Submarine Mortar Mark 10 (A/S Mk.10), was the final development of the forward-throwing anti-submarine weapon Squid, designed during the Second World War and was developed by the Admiralty Underwater Weapons Establishment in the 1950s. Limbo was installed on the quarterdeck of Royal Navy escort ships from 1955 to the mid-1980s, Australian–built destroyer and s. Limbo was widely employed by the Royal Canadian Navy, being incorporated into all destroyer designs from the late 1950s to the early 1970s, including the , , , and classes and the Type 12 President Class frigates built for the South African Navy in the 1960s. Operation Limbo was loaded and fired automatically with the crew under-cover and was stabilised in pitch and roll. The firing distance of the mortars was controlled by opening gas vents; rounds could be fired from . The weapon was linked to the sonar system of the ship, firing on command when the target was in range. The rounds were projected so ...
