Vetehinen-class Submarine
The ''Vetehinen''-class submarine was a Finnish 500-tonne submarine class of three vessels that was designed and built in the 1920s and early 1930s. The ''Vetehinen'' class served in the Finnish Navy during World War II. The class was designed by the Dutch front company Ingenieurskantoor voor Scheepsbouw den Haag (I.v.S) (set up by Germany after World War I in order to maintain and develop German submarine know-how and to circumvent the limitations set by the Treaty of Versailles) and built by the Finnish Crichton-Vulcan shipyard in Turku. The class was based on the German World War I Type UB III and Type UC III submarines and served as prototype for Type VII submarines. The word ''vetehinen'' means a merman. ''Vetehinen''-class submarines were designed as minelaying submarines and were built with mineshafts for 20 mines. Submarines had special inner rails for two torpedo tubes to enable torpedo A modern torpedo is an underwater ranged weapon launched above or bel ...

Crichton-Vulcan
Crichton-Vulcan is an abandoned shipyard in Turku, Finland, that once formed the cornerstone of the Finnish shipbuilding industry. The shipyard is best known for the World War II coastal defence ships and submarines it produced. Shipbuilding at the yard gradually ended after 1976, after a new shipyard had been built in the suburb of Perno. The old yard was taken over by Turku Repair Yard and used for ship repair until 2004, when they too moved to the nearby city of Naantali. The shipyard by the Aura River in Turku then lay abandoned for some time and was the target of vandalism. However, the site is currently being turned into an upper-class residential area. Demolition of the old buildings began in June 2011. History The first shipyard in Turku was established in 1732 on the eastern bank of the Aura River. The first foundry and metal workshop was established in 1842. After the Crimean War the workshop was acquired by Scotsman William Crichton. Crichton built a new sh ...

Ingenieurskantoor Voor Scheepsbouw
(Dutch: engineer-office for shipbuilding), usually contracted to IvS or Inkavos, was a Dutch dummy company set up in The Hague and funded by the after World War I in order to maintain and develop German submarine know-how and to circumvent the limitations set by the Treaty of Versailles. The company designed several submarine types for paying countries, including the Soviet S-class submarine, as well as the prototypes for the German Type II submarines and Type VII submarines. The company was a joint venture by the German shipyards AG Vulcan Stettin (located in Stettin and Hamburg), the Krupp-owned Germaniawerft in Kiel, and AG Weser in Bremen. Design work was carried out at the facilities of these companies in Germany. Background information At the time of IvS, the Germans were bound by the Treaty of Versailles, signed in 1919. This treaty, among other terms, demanded that all German U-boats be destroyed or given to other nations. Thus the ''Reichsmarine'' was left without ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, 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 somet ...

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying naval mine, mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although Torpedo#Classes and diameters, torpedoes of other classes and diameters have been used. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the ...

Naval Mine
A naval mine is a self-contained explosive weapon placed in water to damage or destroy surface ships or submarines. Similar to anti-personnel mine, anti-personnel and other land mines, and unlike purpose launched naval depth charges, they are deposited and left to wait until, depending on their fuzing, they are triggered by the approach of or contact with any vessel. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to create "safe" zones protecting friendly sea lanes, harbours, and naval assets. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake a resource-intensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered.

Merman
A merman (: mermen; also merlad or merboy in youth), the male counterpart of the mythical female mermaid, is a legendary creature which is human from the waist up and fish-like from the waist down, but may assume normal human shape. Sometimes mermen are described as hideous and other times as handsome. Antiquity Perhaps the first recorded merman was the Assyrian-Babylonian sea-god Ea (Babylonian god), Ea (called Enki by the Sumerians), linked to the figure known to the Greeks as Oannes (mythology), Oannes. However, while some popular writers have equated Oannes of the Greek period to the god Ea (and to Dagon), Oannes was rather one of the ''apkallu'' servants to Ea. The ''apkallu'' have been described as "fish-men" in cuneiform texts, and if Berossus is to be believed, Oannes was indeed a being possessed of a fish head and man's head beneath, and both a fish tail and manlike legs. But Berossus was writing much later during the era of Greek rule, engaging in the "construction" o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type VII Submarine
Type VII U-boats were the most common type of German World War II U-boat. 704 boats were built by the end of the war. The type had several modifications. The Type VII was the most numerous U-boat type to be involved in the Battle of the Atlantic. The lone surviving example, , is on display at the Laboe Naval Memorial located in Laboe, Schleswig-Holstein, Germany. At the start of the Second World War the ''Type VII'' class wastogether with the British ''U'', ''S'' and ''T'' class and Dutch ''O 21'' classone of the most advanced submarine classes in service. Design After the defeat in World War I, the Treaty of Versailles forbade Germany to build submarines. Germany circumvented the treaty by setting up the Dutch dummy company ''NV Ingenieurskantoor voor Scheepsbouw Den Haag'' (I.v.S) which continued to design submarines. Based on the World War I design of the Type UB III and its never-built successors Type UF and Type UG, IVS designed the Vetehinen-class submarine and ...

German Type UC III Submarine
Type UC III minelaying submarines were used by the Imperial German Navy () during World War I. They displaced at the surface and submerged, carried guns, 7 torpedoes and up to 14 mines. The ships were double-hulled with improved range and sea-keeping compared to the UC II type. The type had better seagoing, maneuvering and turning capabilities than its predecessor, while underwater stability was reduced. A total of 113 Type UC III submarines were ordered by the Imperial German Navy, but only 25 U-boats were completed before the Armistice with Germany in 1918. Of those, 16 U-boats actually served in the war. 54 building orders were cancelled in 1918, while 34 U-boats were never completed and broken up in the ship yards. Design German Type UC III submarines had a displacement of when at the surface and while submerged. They had a length overall of , a beam of , and a draught of . The submarines were powered by two six-cylinder four-stroke diesel engines each producing (a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type UB III Submarine
The Type UB III submarine was a class of U-boat built during World War I by the German Imperial Navy. Design UB III boats carried 10 torpedoes and were usually armed with either an 8.8 cm SK L/30 naval gun, or a 10.5 cm SK L/45 naval gun, deck gun. They carried a crew of 34 and had a cruising range of . Between 1916 and 1918, 96 were built. The UB III type was a coastal submarine, and being a submersible torpedo boat was less akin to Type UB II submarine, UB II type "attack" (i.e. torpedo-launching) boats that preceded it than the highly successful German Type UC II submarine, UC II type minelaying submarine. The UC IIs had gained their reputation by sinking more than 1,800 Allies of World War I, Allied and Neutral country, neutral vessels. German engineers did not miss the chance of expanding the potential of this capable design by incorporating some of its features into a new submersible torpedo boat.

Treaty Of Versailles
The Treaty of Versailles was a peace treaty signed on 28 June 1919. As the most important treaty of World War I, it ended the state of war between Germany and most of the Allies of World War I, Allied Powers. It was signed in the Palace of Versailles, exactly five years after the assassination of Archduke Franz Ferdinand, which led to the war. The other Central Powers on the German side signed separate treaties. Although the Armistice with Germany (Compiègne), armistice of 11 November 1918 ended the actual fighting, and agreed certain principles and conditions including the payment of reparations, it took six months of Allied negotiations at the Paris Peace Conference (1919–1920), Paris Peace Conference to conclude the peace treaty. Germany was not allowed to participate in the negotiations before signing the treaty. The treaty German disarmament, required Germany to disarm, make territorial concessions, extradite alleged war criminals, agree to Kaiser Wilhelm being p ...
