Seehund
''Seehund'' (German: "seal"), also known as Type XXVII, was a midget submarine built by Nazi Germany during World War II. Designed in 1944 and operated by two-man crews, it was used by the ''Kriegsmarine'' (German Navy) during the closing months of the war, sinking nine merchant vessels and damaging an additional three, while losing 35 boats, mostly attributed to bad weather. The French Navy used four captured boats after the war until 1953. History The origin of the ''Seehund'' began with the salvage of the two British X class submarines and which had been lost by the Royal Navy 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"). XXVIIA (Hecht) Like the British X class boats, the Type XXVIIA was designed to carry explosive charges to be laid beneath enemy ships, but it wa ...

Midget Submarine
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 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 subm ...

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 It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war (1919–1935) of the Weimar Republic.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 submarines (U-boat ...

Schichau-Werke
The Schichau-Werke (F. Schichau, Maschinen- und Lokomotivfabrik, Schiffswerft und Eisengießerei GmbH) was a German engineering works and shipyard based in Elbing, Germany (now Elbląg, Poland) on the Frisches Haff (Vistula Lagoon) of then-East Prussia. It also had a subsidiary shipyard in nearby Danzig (now: Gdańsk, Poland). Due to the Soviet conquest of eastern Germany, Schichau moved to Bremerhaven in March 1945, and its successors continued in business until 2009. Early years Ferdinand Schichau had studied engineering in Berlin, the Rheinland and Great Britain. In 1837, he founded the engineering institution, later known as F. Schichau GmbH, Maschinen- und Lokomotivfabrik (F. Schichau engineering and locomotive factory) in Elbing. It started with the production of hydraulic presses and diggers; in 1860, it began to produce locomotives for the Prussian Eastern Railway. From 1867 locomotive construction began in earnest, and three years later, the factory was connected to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Dönitz
Karl Dönitz (sometimes spelled Doenitz; ; 16 September 1891 24 December 1980) was a German admiral who briefly succeeded Adolf Hitler as head of state in May 1945, holding the position until the dissolution of the Flensburg Government following Germany's unconditional surrender to the Allies days later. As Supreme Commander of the Navy beginning in 1943, he played a major role in the naval history of World War II. He began his career in the Imperial German Navy before World War I. In 1918, he was commanding , and was taken prisoner of war by British forces. While in a POW camp, he formulated what he later called ''Rudeltaktik'' ("pack tactic", commonly called "wolfpack"). By the start of the Second World War, Dönitz was supreme commander of the ''Kriegsmarine'' U-boat arm ( (BdU)). In January 1943, Dönitz achieved the rank of (grand admiral) and replaced Grand Admiral Erich Raeder as Commander-in-Chief of the Navy. Dönitz was the main enemy of Allied naval forces in ...

Ballast Tank
A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural hogging or sagging stresses, or to increase draft, as in a semi-submersible vessel or platform, or a SWATH, to improve seakeeping. Using water in a tank provides easier weight adjustment than the stone or iron ballast used in older vessels, and makes it easy for the crew to reduce a vessel's draft when it enters shallower water, by temporarily pumping out ballast. Airships use ballast tanks mainly to control buoyancy and correct trim. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or argonaut octopus. The concept has been invented and reinvented many times by humans to serve a variety of purpo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sail (submarine)
In naval parlance, the sail (American usage) or fin (British/Commonwealth usage) (also known as a fairwater) of a submarine is the tower-like structure found on the dorsal (topside) surface of submarines. Submarine sails once housed the conning tower (command and communications data center), the periscope(s), radar and communications masts (antenna), though most of these functions have now been relocated to the hull proper (and so the sail is no longer considered a "conning tower"). When above the water's surface, the sail serves as an observation platform. It also provides an entrance and exit point on the submarine that has enough freeboard to prevent the submarine being swamped. Under water, the sail acts as a vertical stabilizer. In some submarines, the sail also supports diving planes (or fairwater planes), which are control surfaces used for underwater stability and steering.Office of Naval ResearchSubmarines - How They Work.

Welman Submarine
The Welman submarine was a Second World War one-man British midget submarine developed by the Special Operations Executive. It only saw action once and was not particularly successful. Design Designed by the Commanding Officer of SOE's Inter Services Research Bureau (ISRB), John Dolphin, Lt Col. John Dolphin, as a method of delivering a large explosive charge below an enemy ship, the Welman was a submersible craft in length (including explosive charge), weighing about . Unlike the "Chariot" human torpedo, the operator was enclosed within the craft, and did not need to wear scuba set, diving gear. The Welman could transport a time-fused explosive charge of Torpex, which was intended to be magnetically attached to a target's hull.Akermann, p. 462 Vision was through armoured glass segments in the small conning tower, and no periscope was fitted. Production Following trials in the Queen Mary Reservoir near Staines towards the end of 1942, the Welman was put into production, the p ...
