Seehund2cele4
''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, 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 (fish), Pike"). XXVIIA (Hecht) Like the British X class boats, the Type XXVIIA was designed to carry explosive charges to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/ submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though ...

Monfalcone
Monfalcone (; Bisiacco: ; fur, Monfalcon; sl, Tržič; archaic german: Falkenberg) is a town and ''comune'' of the province of Gorizia in Friuli Venezia Giulia, northern Italy, located on the Gulf of Trieste. Monfalcone means 'falcon mountain' in Italian (see '' Montfaucon'' in French and '' Falkenberg'' in Germanic languages). It is a major industrial centre for manufacturing ships, airplanes, textiles, chemicals, and refined oil, and the home of the Fincantieri cruise ship building company. Monfalcone is the northernmost city on the Mediterranean Sea. Geography Monfalcone is the fifth most populous town in Friuli Venezia Giulia and the main centre of Bisiacaria territory. Joined to its neighbourhoods, it has about 50,000 inhabitants. The town lies between the Karst hills and the Adriatic coast, and it is the northernmost port of the Mediterranean Sea. History In prehistoric times the area of Monfalcone housed several fortified villages called '' castellieri''. After th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cantieri Riuniti Dell'Adriatico
Cantieri Riuniti dell'Adriatico ("United Shipbuilders of the Adriatic") was an Italian manufacturer in the sea and air industry which was active from 1930 to 1966. This shipyard is now owned by Fincantieri. History In 1930, Stabilimento Tecnico Triestino based at Trieste merged with another Italian company, the Cantiere Navale Triestino of Monfalcone, forming the ''Cantieri Riuniti dell'Adriatico'' (CRDA). The new company built a number of light and heavy cruisers for the Regia Marina (Royal Italian Navy) between the wars, as well as some 27 submarines. The ocean liner ''Conte di Savoia'' was also constructed in 1932. During the World War II, CRDA Trieste built two battleships for the Regia Marina, ''Vittorio Veneto'' and ''Roma''. CRDA survived the postwar shakeup in the shipbuilding industry and went on to build several more commercial liners in the 1950s and 1960s, as well as a few naval vessels. In 1984, CRDA was sold to the Fincantieri Group. For the Olympic regatta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 connect ... [...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.

Gyrocompass
A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth (or another planetary body if used elsewhere in the universe) to find geographical direction automatically. The use of a gyrocompass is one of the seven fundamental ways to determine the heading of a vehicle. A gyroscope is an essential component of a gyrocompass, but they are different devices; a gyrocompass is built to use the effect of gyroscopic precession, which is a distinctive aspect of the general gyroscopic effect. Gyrocompasses are widely used for navigation on ships, because they have two significant advantages over magnetic compasses: * they find true north as determined by the axis of the Earth's rotation, which is different from, and navigationally more useful than, ''magnetic'' north, and * they are unaffected by ferromagnetic materials, such as in a ship's steel hull, which distort the magnetic field. Aircraft commonly use gyroscopic instrum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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), 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 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 production being contrac ...

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 for ...
