Submarines
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type UB I Submarine
The Type ''UB I'' submarine (sometimes known as the ''UB-1'' class) was a class of small coastal submarines (U-boats) built in Germany at the beginning of the First World War. 20 boats were constructed, most of which went into service with the German Imperial Navy.(german: Kaiserliche Marine) Boats of this design were also operated by the Austro-Hungarian Navy (Kaiserliche und Königliche Kriegsmarine ''or'' K.u.K. Kriegsmarine) and the Bulgarian Navy. In the Austro-Hungarian Navy, it was called the . Built to meet the need for small maneuverable submarines able to operate in the narrow, shallow seas off Flanders, the vessels were intended to be quickly constructed, then shipped by rail and assembled at their port of operation. The design effort began in mid-August 1914 and by mid-October the first 15 boats were ordered from two German shipyards. The German Imperial Navy subsequently ordered an additional pair of boats to replace two sold to Austria-Hungary, who ordere ...

German Type UC I Submarine
The Type UC I coastal submarines were a class of small minelaying U-boats built in Germany during the early part of World War I. They were the first operational minelaying submarines in the world (although the Russian submarine ''Krab'' was laid down earlier). A total of fifteen boats were built. The class is sometimes also referred to as the ''UC-1'' class after , the class leader. The Italian X-class submarine was a reverse-engineered and modified type of the UC-1-class. Design These submarines were designed by Dr. Werner of the Torpedo Inspectorate, and based on the Type UB I small coastal submarines, with a revised bow section housing inclined minelaying tubes and uprated engines to compensate for the increased displacement and less streamlined form. The boats' sole armament was six internal mine tubes with 12 mines, although ''UC-11'' was fitted with a single external torpedo tube in 1916. They were constructed very quickly, and suffered from problems with their minelayi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Type II Submarine
The Type II U-boat was designed by Nazi Germany as a coastal U-boat, modeled after the CV-707 submarine, which was designed by the Dutch dummy company NV Ingenieurskantoor voor Scheepsbouw Den Haag (I.v.S) (set up by Germany after World War I in order to maintain and develop German submarine technology and to circumvent the limitations set by the Treaty of Versailles) and built in 1933 by the Finnish Crichton-Vulcan shipyard in Turku, Finland. It was too small to undertake sustained operations far away from the home support facilities. Its primary role was found to be in the training schools, preparing new German naval officers for command. It appeared in four sub-types. Background Germany was stripped of its U-boats by the Treaty of Versailles at the end of World War I, but in the late 1920s and early 1930s began to rebuild its armed forces. The pace of rearmament accelerated under Adolf Hitler, and the first Type II U-boat was laid down on 11 February 1935. Knowing that the w ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 205 Submarine
The Type 205 was a class of German diesel-electric submarines. They were single- hull vessels optimized for the use in the shallow Baltic Sea. The Type 205 is a direct evolution of the Type 201 class with lengthened hull, new machinery and sensors. The biggest difference though is that ST-52 steel is used for the pressure hull since the Type 201's non-magnetic steel proved to be problematic. Type 206, the follow-on class, finally succeeded with non-magnetic steel hulls. The Type 205 was in service with the Royal Danish Navy until 2004, in which it was known as ''Narhvalen'' class. The Danish boats differed slightly from the German ones to meet special Danish demands. Responsible for the design and construction was the Ingenieurkontor Lübeck (IKL) headed by Ulrich Gabler. List of boats These last two boats were built by the Howaldtswerke, in Denmark at The Naval Dockyard, Copenhagen. Notes: * ''U-1'' was given back to Nordseewerke and was used to test an experimental closed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesmarine
The German Navy (, ) is the navy of Germany and part of the unified ''Bundeswehr'' (Federal Defense), the German Armed Forces. The German Navy was originally known as the ''Bundesmarine'' (Federal Navy) from 1956 to 1995, when ''Deutsche Marine'' (German Navy) became the official name with respect to the 1990 incorporation of the East German ''Volksmarine'' (People's Navy). It is deeply integrated into the NATO alliance. Its primary mission is protection of Germany's territorial waters and maritime infrastructure as well as sea lines of communication. Apart from this, the German Navy participates in peacekeeping operations, and renders humanitarian assistance and disaster relief. It also participates in anti-piracy operations. History The German Navy traces its roots back to the ''Reichsflotte'' (Imperial Fleet) of the revolutionary era of 1848–52. The ''Reichsflotte'' was the first German navy to sail under the black-red-gold flag. Founded on 14 June 1848 by the orders o ...

Lead Boat
The lead ship, name ship, or class leader is the first of a series or class of ships all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take as many as five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in the class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost-effective than building prototypes, and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to the lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following ship ...

U-7 Class Submarine (Austria-Hungary)
The Type U 66 was a class of five submarines or U-boats operated by the German Imperial Navy (german: Kaiserliche Marine) during World War I. The class is alternately referred to as the ''U-66''-class or the Type UD. The class was built by Germaniawerft of Kiel to their 506d design as the ''U-7''-class for the Austro-Hungarian Navy. The five boats were sold to the Imperial Germany Navy at the beginning of World War I when it was thought impossible for the submarines to reach the Mediterranean for delivery to Austria-Hungary. The Austro-Hungarian Navy, after competitively evaluating six submarines of three foreign designs, selected the Germaniwerft 506d or Type UD design over a design from Whitehead & Co. for the ''U-7'' class. The boats, numbered ''U-7'' to ''U-11'', were designed to be long and displace between when surfaced and submerged. They were to be armed with five torpedo tubes and a deck gun. For propulsion the design called for twin diesel engines for surface r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
