German Type U 87 Submarine
Type 87 was a class of U-boats built during World War I by the Kaiserliche Marine. Type 87 U-boats carried 16 torpedoes and had various arrangements of deck guns. ''U 87'' and ''U 89'' had one 10.5 cm/45 and one 8.8 cm deck gun, U 88 was probably equally armed. ''U 90'' - ''U 92'' were armed with one 10.5 cm/45 gun (140-240 rounds). They carried a crew of 36 and had excellent seagoing abilities with a cruising range of approximately . Many arrangements from the Type 81, 87, and 93 were also seen on the World War II Type IX U-boats when their design work took place 20 years later. Compared to the previous type 81, the 87s were shorter, while the pressure hull was shortened . They were slower on the surface, and slower submerged, but increased range by to at 8 knots. They carried 16 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 ei ...

Kiel
Kiel () is the capital and most populous city in the northern Germany, German state of Schleswig-Holstein, with a population of 246,243 (2021). Kiel lies approximately north of Hamburg. Due to its geographic location in the southeast of the Jutland peninsula on the southwestern shore of the Baltic Sea, Kiel has become one of Germany's major maritime centres, known for a variety of international sailing events, including the annual Kiel Week, which is the biggest sailing event in the world. Kiel is also known for the Kiel mutiny, Kiel Mutiny, when sailors refused to board their vessels in protest against Germany's further participation in World War I, resulting in the abdication of the Wilhelm II, German Emperor, Kaiser and the formation of the Weimar Republic. The Olympic sailing competitions of the 1936 Summer Olympics, 1936 and the 1972 Summer Olympics#Venues, 1972 Summer Olympics were held in the Bay of Kiel. Kiel has also been one of the traditional homes of the German Nav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaiserliche Werft Danzig
Kaiserliche Werft Danzig was a German shipbuilding company founded in 1852 as ''Königliche Werft Danzig'' and renamed ''Kaiserliche Werft'' after the proclamation of the German Empire in 1871. Together with Kaiserliche Werft Kiel and Kaiserliche Werft Wilhelmshaven it was one of three shipyards responsible for maintenance, repair and construction of warships for the Imperial German Navy. ''Kaiserliche Werft Danzig'' closed in 1918 after the end of World War I, but soon opened when Danziger Werft was founded on its site in 1919. History The history of the Danzig shipyard started 1844 when some area on both sides of the river Tote Weichsel at Danzig became property of the Royal Prussian Government. Named ''Marinedepot'' (1849–54) it was first only used as a depot and anchoring space for the few Prussian warships at the time. At the end of 1853 it became ''Königliche Werft Danzig'' (1854 – 1871), and was subsequently named ''Kaiserliche Werft Danzig'' (1871 – 1918) ...

German Type U 81 Submarine
Type 81 was a class of U-boats built during World War I by the Kaiserliche Marine. Type 81 U-boats carried 12 torpedoes and had various arrangements of deck guns. U 81 to U 83 had one deck gun with 140-240 rounds. U 84 - U 86 were constructed with two deck guns. In 1917, U 84 - U 86 were converted to a carry one 10.5 cm and one 8.8 cm deck gun and carried 240 rounds. They carried a crew of four officers and 31 men and had excellent seagoing abilities with a cruising range of around . Many arrangements from the Type 81 and the next two types were also seen on the World War II Type IX The Type IX U-boat was designed by Nazi Germany's '' Kriegsmarine'' in 1935 and 1936 as a large ocean-going submarine for sustained operations far from the home support facilities.

German Type U 93 Submarine
Type 93 was a class of U-boats built during World War I by the Kaiserliche Marine. Type 93 U-boats carried 16 torpedoes and had various arrangements of deck guns. As with the type 81 and 87, some had only one SK L/30 deck gun while others had a single SK L/45 gun and some were initially equipped with both. In 1917 some of the boats were refitted with a single 10.5 cm gun and 220 rounds. These boats carried a crew of 39 and had excellent seagoing abilities with a cruising range of around . Many arrangements from the Type 81, 87 and 93 were also seen on 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.

Pressure Hull
A submarine hull has two major components, the ''light hull'' and the ''pressure hull''. The light hull (''casing'' in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape. The pressure hull is the inner hull of a submarine that maintains structural integrity with the difference between outside and inside pressure at depth. Shapes Modern submarines are usually cigar-shaped. This design, already visible on very early submarines, is called a "teardrop hull". It is structurally efficient for withstanding external pressure, and significantly reduces the hydrodynamic drag on the sub when submerged, but decreases the sea-keeping capabilities and increases drag while surfaced. History The concept of an outer hydrodynamically streamlined light hull separated from the inner pressure hull was first introduced in the early pioneering submarine Ictineo I designed by the Spanish inventor Narcís Monturiol in 1859. However, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 other sizes of torpedo tube have been used: see Torpedo#Classes and diameters, Torpedo classes and diameters. 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 t ...

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 naval mine, 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 naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...

U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Kaiserliche Marine
{{italic title The adjective ''kaiserlich'' means "imperial" and was used in the German-speaking countries to refer to those institutions and establishments over which the ''Kaiser'' ("emperor") had immediate personal power of control. The term was used particularly in connexion with the Roman-German Emperor as sovereign of the Holy Roman Empire and with the subsequent Empire of Austria. In the Early Modern Period the term is linked with the universal precedence of the ''Kaiser'' over the other princes of the realm. Holders of an imperial or ''kaiserliche'' office were recruited from the whole empire, and had wide-ranging privileges in the territories. Examples of military, political and cultural institutions with ''kaiserliche'' players in the Holy Roman Empire are the: * ''Kaiserliche Armee'' ( Imperial Army) and * ''Kaiserliche Reichspost'' (Imperial Post Office) of the Roman-German Emperor (to 1806) (Habsburg, only 1742–1745 Wittelsbach) * ''kaiserliches Hofgestüt'' (Im ...

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] |
