Human Torpedoes
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 harbors. The human torpedo concept has occasionally been used by recreational divers, although this use is closer to midget submarines. History of common wartime models The concept of a small, manned submarine carrying a bomb was developed and patented by a British naval officer in 1909, but was never used during the First World War. The Italian Navy experimented with a primitive tiny sub (Mignatta) carrying two men and a limpet mine: this craft successfully sank Austro-Hungarian battleship SMS ''Viribus Unitis'' on 1 November 1918. The first truly practical human to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: *Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. *** Blast: A strong shock wave is provided by the detonation of the explosive. ***Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. ***Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag ...

Diving Plane
Diving planes, also known as hydroplanes, are control surfaces found on a submarine which allow the vessel to pitch its bow and stern up or down to assist in the process of submerging or surfacing the boat, as well as controlling depth when submerged. Bow and stern planes Diving planes are usually fitted in two pairs, the '' bow planes'' at the front of the submarine and the ''stern planes'' at the rear. The stern planes function in much the same way as an aircraft's elevator. As the planes are a long distance fore-and-aft from the hull's centre of buoyancy, they introduce a pitching moment. Ballast tanks within the submarine adjust buoyancy to be neutral, making the boat controllable. The position of the planes controls the pitch of the boat and, with the forward motion of the boat, this controls depth. If not carefully controlled, this could lead to a 'porpoising' motion whereby the planesman continually hunts for a stable combination of depth and pitch. For easier berth ...

European Pine Marten
The European pine marten (''Martes martes''), also known as the pine marten, is a mustelid native to and widespread in most of Europe, Asia Minor, the Caucasus and parts of Iran, Iraq and Syria. It is listed as Least Concern on the IUCN Red List. It is less commonly also known as baum marten, or sweet marten. Description The European pine marten's fur is usually light to dark brown. It is short and coarse in the summer, growing longer and silkier during the winter. It has a cream- to yellow-coloured "bib" marking on its throat. Its body is up to long, with a bushy tail of about . Males are slightly larger than females; typically, it weighs around . It has excellent senses of sight, smell, and hearing. Distribution and habitat The European pine marten inhabits well-wooded areas. UK and The Republic of Ireland In Great Britain, the species was for many years common only in northwestern Scotland. A study in 2012 found that martens have spread from their Scottish Highl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marder (submarine)
''Marder'' (Pine Marten) was a German midget submarine developed from the ''Neger''. The craft was long and unlike the ''Neger'' included a flooding tank in the nose allowing it to dive. Another improvement was the dome through which the pilot viewed the outside world that also served as the craft's entrance and exit was made openable from the inside. Maximum diving depth was about . The submarine's first operations took place on the night of 2 August 1944, when Nazi Germany's ''Kriegsmarines '' Small Battle Units'' made their largest effort of the war. 58 human torpedoesBrown p. 116 of the ''Neger''-type and 22 ''Linse'' vessels were launched against Allied shipping off Normandy as part of a combined operation with ''Neger''s and explosive ''Linse'' boats. One Royal Navy destroyer escort, was sunk by a human torpedo along with one minesweeper, , and one landing craft Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing ...

Neger
The ''Neger'' (German for ''Negro'') was a torpedo-carrying craft generally described as a human torpedo which could not submerge, but was difficult to see during night operations. The vessel was used by Nazi Germany's ''Kriegsmarine'' between 1943 and 1945. The name comes from its constructor, Richard Mohr, whose surname in German also stands for Negro in the racial sense. Design The Neger was based on the G7e torpedo and sported a spartan cockpit covered by a perspex dome, where the warhead would have been. It had sufficient positive buoyancy to run awash while supporting a second G7e, with warhead, slung below. The vessel had a range of 48 nautical miles at 4 knots and displaced 2.7 tons. The pilot navigated via a wrist compass and air was provided through a Dräger self-contained breathing device. The pilot aimed his weapon by lining up an aiming spike on the nose with a graduated scale on the dome. Subsequently, a second aiming spike was added closer to the dome. It, how ...

Kriegsmarine
The (, ) was the navy of Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war (1919–1935) of the Weimar Republic. The was one of three official branches, along with the and the , of the , the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles, the grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines. ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supported the Nationalists against the Spanish Republicans. In January 1939, Plan Z, a massive shipbuilding program, was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building program for submarine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-class Submarine
The X class was a World War II midget submarine class built for the Royal Navy during 1943–44. It was substantially larger than the original Chariot manned torpedo. Known individually as X-Craft, the vessels were designed to be towed to their intended area of operations by a full-size "mother" submarine – usually one of the T class or S class – with a passage crew on board, the operational crew being transferred from the towing submarine to the X-Craft by dinghy when the operational area was reached, and the passage crew returning with the dinghy to the towing submarine. Once the attack was over, the X-Craft would rendezvous with the towing submarine and then be towed home. Range was limited primarily by the endurance and determination of their crews, but was thought to be up to 14 days in the craft or 1,200 miles (1931 km) distance after suitable training. Actual range of the X-Craft itself was surfaced and at submerged. Specification The craft was about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chariot Manned Torpedo
The Chariot was a British manned torpedo used in World War II. The Chariot was inspired by the operations of Italian naval commandos, in particular the raid on 19 December 1941 by members of the Decima Flottiglia MAS who rode "''Maiali"'' human torpedoes into the port of Alexandria and there placed limpet mines on or near the battleships HMS ''Valiant'' and HMS ''Queen Elizabeth'' as well as an 8,000-ton tanker, causing serious damage which put both battleships out of operational use until 1943. History Official development of the Chariot began in April 1942, primarily led by two officers of the Royal Navy's submarine service: Commander Geoffrey Sladen DSO*, DSC and Lieutenant Commander William Richmond "Tiny" Fell CMG, CBE, DSC. Training of crews was based out of the depot ship HMS ''Titania'' initially stationed at Gosport and later in Scotland at Loch Erisort (known as port "HZD"), Loch a' Choire (known as port "HHX") and Loch Cairnbawn (known as port "HHZ") and out of H ...

Cockpit (sailing)
A cockpit is a name for the location of controls of a vessel; while traditionally an open well in the deck of a boat outside any deckhouse or cabin, in modern boats they may refer to an enclosed area. Smaller boats typically have an ''aft cockpit,'' towards the stern of the boat, whereas larger vessels may provide a ''center cockpit'' with greater protection from weather. On a recreational sailboat, the cockpit is considered the most safe external location for crew. A bridge deck is a raised separation between an external cockpit and cabin or saloon, used to keep water from astern from entering from the cockpit, especially in following seas. History In the Royal Navy, the term cockpit originally referred to the area where the coxswain was stationed. This led to the word being used to refer to the area towards the stern of a small decked vessel that houses the rudder controls.

Tanker (ship)
A tanker (or tank ship or tankship) is a ship designed to transport or store liquids or gases in bulk. Major types of tankship include the oil tanker, the chemical tanker, and gas carrier. Tankers also carry commodities such as vegetable oils, molasses and wine. In the United States Navy and Military Sealift Command, a tanker used to refuel other ships is called an oiler (or replenishment oiler if it can also supply dry stores) but many other navies use the terms tanker and replenishment tanker. Tankers were first developed in the late 19th century as iron and steel hulls and pumping systems were developed. As of 2005, there were just over 4,000 tankers and supertankers or greater operating worldwide. Description Tankers can range in size of capacity from several hundred tons, which includes vessels for servicing small harbours and coastal settlements, to several hundred thousand tons, for long-range haulage. Besides ocean- or seagoing tankers there are also specia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
