hedgehog depth charge


This p… As the mortar projectiles employed contact fuzes rather than time or barometric (depth) fuzes, detonation occurred directly against a hard surface such as the hull of a submarine making it more deadly than depth charges, which relied on damage caused by hydrostatic shockwaves.The system was developed to solve the problem of the target submarine disappearing from the attacking ship's ASDIC when the ship came within the sonar's minimum range.By summer of 1943, the German U-boat campaign was experiencing severe setbacks in the face of massive anti-submarine efforts integrating Coastal Command attacks in the Bay of Biscay, the deployment of merchant aircraft carriers in convoys, new anti-submarine technologies such as hedgehog and improved radar, and the use of dedicated hunter-killer escort groups.From 1949, a copy of Hedgehog was produced in the USSR as MBU-200, developed in 1956 into MBU-600 (also known as RBU-6000) with increased range of 600 m.Three "Hedgerow" flotillas of specialized Landing Craft Assault boats carrying the Hedgehog instead of troops were used during the Normandy landings.Directorate of Miscellaneous Weapons DevelopmentThe design of the Bombards was the basis for the Royal Navy anti-submarine weapon known as the Hedgehog.Through the application of the Squash head and HEAT technology they had a role in the development and production of Lt-Col Stewart Blacker's Blacker Bombard, the PIAT (Blacker's smaller version of the bombard matched to a hollow charge warhead, Hedgehog (effectively an adaption of the Bombard spigot mortar principle working with the Navy's Directorate of Miscellaneous Weapons Development) and tank variants including the AVRE with its "Flying Dustbin" 290mm Petard spigot mortar, and a bridge-laying tank.Limbo, a three-barreled mortar similar to the earlier Hedgehog and Squid which it superseded, was developed by the Admiralty Underwater Weapons Establishment in the 1950s.The United States produced a rocket version of Hedgehog called Mousetrap, then Weapon Alpha as a replacement for both.This secret research by the Directorate of Miscellaneous Weapons Development (DMWD) led to the development of the Hedgehog.The "Hedgehog", so named because the empty rows of its launcher spigots resembled the spines of a hedgehog, was a replacement for the unsuccessful Fairlie Mortar that was trialled aboard in 1941. Depth charges were first developed by the British Royal Navy in 1916. [2] It was deployed on convoy escort warships such as destroyers and corvettes to supplement the depth charges. Because of the The first Hedgehog kill in the Pacific was The Hedgehog (also known as an Anti-Submarine Projector) was a forward-throwing anti-submarine weapon that was used primarily during the Second World War.The device, which was developed by the Royal Navy, fired up to 24 spigot mortars ahead of a ship when attacking a U-boat. Other, more conventional depth charges … The propelling charge was part of the main weapon and worked against a rod (the spigot) set in the baseplate which fitted inside a tubular tail of the 'bomb'. first Hedgehog kill did not take place until

were This had the added advantage of minimising the stress on the weapon's mounting, so that deck reinforcement was not needed, and the weapon could easily be retrofitted to any convenient place on a ship. The In February 1917 the USN Bureau of Ordnance began production of the first USA depth charge, the Mark 1, producing over 10,000 units during the war although it was found to be unreliable and not powerful enough to sink a … was winding down with the Squid advanced depth charge thrower.Part of the impetus for developing Hedgehog was Reloading took about three minutes.The system was developed to solve the problem of the target submarine disappearing from the attacking ship'sIn response to this new deadly threat to its U-boats, the1940s shipboard multi-barrel anti-submarine mortar weapon of British originThe Hedgehog had four key advantages over the depth charge:When the United States entered World War II at the end of 1941, the United States Navy found itself deficient in ocean escort-type vessels. November 1942, and the best tactics for its effective use were not The Hedgehog (also known as an Anti-Submarine Projector) was a forward-throwing anti-submarine weapon that was used primarily during the Second World War.The device, which was developed by the Royal Navy, fired up to 24 spigot mortars ahead of a ship when attacking a U-boat. The device, which was developed by the Royal Navy, fired up to 24 spigot mortars ahead of a ship when attacking a U-boat.The Australian Army adapted the marine Hedgehog into a land-based seven-shot launcher that could be mounted on the back of Matilda tanks.It projected multiple small anti-submarine bombs simultaneously, 10 from each side of the ship's forecastle, each containing 20 pounds of explosive, but "Hedgehog" projecting 24 small bombs from a single platform eventually became the predominant British weapon in the war.In response to this new deadly threat to its U-boats, the Kriegsmarine brought forward its programme of acoustic torpedoes in 1943, beginning with the Falke.This principle was first used on the Blacker Bombard 29 mm Spigot Mortar and the later PIAT anti-tank weapon.Department of Miscellaneous Weapons DevelopmentIt was deployed on convoy escort warships such as destroyers and corvettes to supplement the depth charges.It is similar in principle to the Royal Navy Hedgehog system used during the Second World War.The Hedgehog (also known as an Anti-Submarine Projector) was a forward-throwing anti-submarine weapon that was used primarily during the Second World War.In late 1943 the Royal Navy introduced Squid.The troop well was filled by a Hedgehog spigot mortar weapon.It was deployed on convoy escort warships such as destroyers and corvettes to supplement the depth charges. Unlike depth charges, the hedgehog shells did not go off unless they scored a hit. The Royal Navy’s Hedgehog depth charge of World War II consisted of a salvo of 24 small high-explosive bombs that could be launched to a distance of 250 yards (228 metres) and which exploded on contact as they sank through the water.

MBU-600 and its derivatives remain an important part of the Russian Navy's (as well as Russia's allies, such as India) anti-submarine arsenal to this day.From 1949, a copy of Hedgehog was produced in theThe Australian Army adapted the marine Hedgehog into a land-based seven-shot launcher that could be mounted on the back ofThe United States produced a rocket version of Hedgehog calledThe adaptation of the bombard for naval use was made in partnership with The spigot design allowed a single device to fire warheads of varying size. The firing sequence was staggered so all the bombs would land at about the same time. Encyclopedia © 2007, 2010, 2012, 2014 by Kent G. Budge.Navweaps.com
