Midget Submarines
A midget submarine (also called a mini 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 designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-craft and the unsuccessful Welman submarine, were specifically designed with ...

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, ho ...

Schwertwal
''Schwertwal'' (German for Orca, lit. "Sword Whale") was a German miniature submarine design that reached the trial stage in late April 1945. It had a crew of two and was designed to have a high subsurface speed of around 20 knots. The high speed was archived by the use of a Walther turbine. The submarine carried an armament of two torpedoes. The submarine lacked a periscope and the pilot viewed the outside world through an acrylic glass dome. The prototype was scuttled at the end of World War II but was raised by the British 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 Fr ... and examined before being scrapped.

Molch
''Molch'' (German language: "newt" or "salamander") was an unsuccessful series of one-man midget submarines created during World War II. Built in 1944, it was the first mini-submarine of Nazi Germany's ''Kriegsmarine'', but was not successful in combat operations and suffered heavy losses. Description The Molch was based on torpedo technology, and carried two G7e torpedoes attached externally on either side of the craft. It was fully electrical and was created for coastal operations, with a range of at . The front section of the boat held a large battery. Behind the battery was the operator's position, which sat between two small trimming tanks. Behind the operator sat the electric motor. The complicated system of tanks made it difficult to control during combat operations. The first of 393 boats were delivered on June 12 1944 and were built by AG Weser in Bremen. Operational history The Molch were first used in the Mediterranean against the Allied "Operation Dragoon" ...

Marder (midget 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 ...

Hecht (submarine)
''Hecht'' (German: " Pike"), also known as Type XXVIIA, was a two-man all-electric German midget submarine created during World War II. History The origin of the ''Hecht'' began with the salvage of the two British X class submarines and which had been sunk during Operation Source, an attempt to sink the German battleship Tirpitz. ''Hauptamt Kriegschiffbau'' subsequently produced a design for a two-man submarine based on inspection of the British boats, designated Type XXVIIA and named ''Hecht'' ("Pike") Like the British X class boats, the Type XXVIIA was designed to carry explosive charges to be laid beneath enemy ships, but it was markedly smaller and had substantial differences from the X class. It dispensed with a dual diesel/electric propulsion system, relying instead solely on electrical power in the form of a 12 hp AEG torpedo motor, on the basis that since it would operate submerged there was no need for a diesel engine. However, this resulted in a very low enduran ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hai (midget Submarine)
''Hai'' (shark) was an advanced model of the Marder-class midget submarines created in Nazi Germany during World War II and operated by the K-Verband The K-Verband (in English "small battle unit", derived from ''Kleinkampfverbände der Kriegsmarine'' "small battle units") was a World War II German naval unit that operated a mixture of midget submarine A midget submarine (also called a mini su .... Its prototype performed poorly during test runs and therefore no other boats were produced. The ''Hai'' was long and its length allowed for larger batteries, giving it the maximum speed of under water. In addition, the ''Hai'' could remain under water for up to two hours.
