German Cruiser Admiral Scheer
() was a heavy cruiser (often termed a ''pocket battleship'') which served with the (Navy) of Nazi Germany during World War II. The vessel was named after Admiral Reinhard Scheer, German commander in the Battle of Jutland. She was laid down at the shipyard in Wilhelmshaven in June 1931 and completed by November 1934. Originally classified as an armored ship () by the ''Reichsmarine'', in February 1940 the Germans reclassified the remaining two ships of this class as heavy cruisers. The ship was nominally under the limitation on warship size imposed by the Treaty of Versailles, though with a Full-load displacement, full load displacement of , she significantly exceeded it. Armed with six guns in two triple gun turrets, and her sisters were designed to outgun any cruiser fast enough to catch them. Their top speed of left only a handful of ships in the Anglo-French navies able to catch them and powerful enough to sink them. saw heavy service with the German Navy, includ ...

Nazi Germany
Nazi Germany, officially known as the German Reich and later the Greater German Reich, was the German Reich, German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a Totalitarianism, totalitarian dictatorship. The Third Reich, meaning "Third Realm" or "Third Empire", referred to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which the Nazis referred to as the Thousand-Year Reich, ended in May 1945, after 12 years, when the Allies of World War II, Allies defeated Germany and entered the capital, Berlin, End of World War II in Europe, ending World War II in Europe. After Hitler was appointed Chancellor of Germany in 1933, the Nazi Party began to eliminate political opposition and consolidate power. A 1934 German referendum confirmed Hitler as sole ''Führer'' (leader). Power was centralised in Hitler's person, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelmshaven
Wilhelmshaven (, ''Wilhelm's Harbour''; Northern Low Saxon: ''Willemshaven'') is a coastal town in Lower Saxony, Germany. It is situated on the western side of the Jade Bight, a bay of the North Sea, and has a population of 76,089. Wilhelmshaven is the centre of the "Jade Bay" business region (which has around 330,000 inhabitants) and is Germany's main military port. The adjacent Lower Saxony Wadden Sea National Park (part of the Wattenmeer UNESCO World Natural Heritage Site) provides the basis for the major tourism industry in the region. History The , built before 1383, operated as a pirate stronghold; the Hanseatic League destroyed it in 1433. Four centuries later, the Kingdom of Prussia planned a fleet and a harbour on the North Sea. In 1853, Prince Adalbert of Prussia, a cousin of the Prussian King Frederick William IV of Prussia, Frederick William IV, arranged the Jade Treaty (''Jade-Vertrag'') with the Grand Duchy of Oldenburg, in which Prussia and the Grand Duchy ente ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Length Overall
Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often reported. T ...

Admiral Scheer ONI Schematic
Admiral is one of the highest ranks in many navies. In the Commonwealth nations and the United States, a "full" admiral is equivalent to a "full" general in the army or the air force. Admiral is ranked above vice admiral and below admiral of the fleet, or fleet admiral. Etymology The word in Middle English comes from Anglo-French , "commander", from Medieval Latin , . These evolved from the Arabic () – () (), "king, prince, chief, leader, nobleman, lord, a governor, commander, or person who rules over a number of people" and (), the Arabic definite article meaning "the." In Arabic, admiral is also represented as (), where al-Baḥr (البحر) means the sea. The 1818 edition of Samuel Johnson's ''A Dictionary of the English Language'', edited and revised by the Rev. Henry John Todd, states that the term "has been traced to the Arab. emir or amir, lord or commander, and the Gr. , the sea, q. d. ''prince of the sea''. The word is written both with and without the d, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kara Sea
The Kara Sea is a marginal sea, separated from the Barents Sea to the west by the Kara Strait and Novaya Zemlya, and from the Laptev Sea to the east by the Severnaya Zemlya archipelago. Ultimately the Kara, Barents and Laptev Seas are all extensions of the Arctic Ocean north of Siberia. The Kara Sea's northern limit is marked geographically by a line running from Cape Kohlsaat in Graham Bell Island, Franz Josef Land, to Cape Molotov (Arctic Cape), the northernmost point of Komsomolets Island in Severnaya Zemlya. The Kara Sea is roughly long and wide with an area of around and a mean depth of . Its main ports are Novy Port and Dikson and it is important as a fishing ground although the sea is ice-bound for all but two months of the year. The Kara Sea contains the East-Prinovozemelsky field (an extension of the West Siberian Oil Basin), containing significant undeveloped petroleum and natural gas. In 2014, US government sanctions resulted in Exxon having unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Wunderland
Operation Wonderland () was an operation from 16 to 30 August 1942 by the ''Kriegsmarine'' in the Barents Sea and the Kara Sea off the Arctic coast of the Soviet Union. The operation was an attack on Soviet shipping using the Northern Sea Route which ran along the Soviet Arctic coast from the Bering Strait, westwards along Siberia to the Kara Sea. The operation was the first part of a campaign to dominate the seas of the western Arctic. Reports from Japanese naval intelligence alerted the Germans to the sailing of a convoy, EON-18. The German cruiser supported by five U-boats and reconnaissance aircraft sailed on 16 August for the Kara Sea where it encountered pack ice. The cruiser carried an Arado Ar 196 reconnaissance floatplane which found several groups of ships. ''Admiral Scheer'' sank the icebreaker '' A. Sibiryakov'' and bombarded the Soviet base at Dikson before returning to its base at Kirkenes in northern Norway. The meagre result obtained by ''Admiral Scheer'' was ex ...

Convoy PQ 17
Convoy PQ 17 was an Allied Arctic convoy during the Second World War. On 27 June 1942, the ships sailed from Hvalfjörður, Iceland, for the port of Arkhangelsk in the Soviet Union. The convoy was located by German forces on 1 July, shadowed and attacked. The First Sea Lord, Admiral Sir Dudley Pound, acting on information that German ships, including , were moving to intercept, ordered the covering force, based on the Allied battleships and away from the convoy and told the convoy to scatter. Because of vacillation by ''Oberkommando der Wehrmacht'' (OKW, German armed forces high command), the ''Tirpitz'' raid never materialised. The convoy was the first large joint Anglo-American naval operation under British command; in Churchill's view this encouraged a more careful approach to fleet movements. As the close escort and the covering cruiser forces withdrew westwards to intercept the German raiders, the merchant ships were left without escorts. The freighters were attacked ...

Capital Ship
The capital ships of a navy are its most important warships; they are generally the larger ships when compared to other warships in their respective fleet. A capital ship is generally a leading or a primary ship in a naval fleet. Strategic implications There is usually no formal criterion for the classification, but it is a useful concept in naval strategy; for example, it permits comparisons between relative naval strengths in a theatre of operations without the need for considering specific details of tonnage or gun diameters. A notable example of this is the Alfred Thayer Mahan, Mahanian doctrine, which was applied in the Sinking of Prince of Wales and Repulse, planning of the defence of Singapore in World War II, where the Royal Navy had to decide the allocation of its battleships and battlecruisers between the Atlantic and Pacific theatres. The Mahanian doctrine was also applied by the Imperial Japanese Navy, leading to its Preventive war, preventive move to Attack on P ...

Almería
Almería (, , ) is a city and municipalities in Spain, municipality of Spain, located in Andalusia. It is the capital of the province of Almería, province of the same name. It lies in southeastern Iberian Peninsula, Iberia on the Mediterranean Sea. Caliph Abd al-Rahman III founded the city in 955. The city grew wealthy during the Islamic era, becoming a world city throughout the 11th and 12th centuries. It enjoyed an active port that traded Almerían silk, silk, oil, and raisins. Being adjacent to a small desert, Almería has an exceptionally dry climate by European standards. Etymology The name "Almería" comes from the city's former Arabic name, ''Madīnat al-Mariyya'', meaning "city of the watchtower". As the settlement was originally the port or coastal suburb of Pechina, it was initially known as ''Mariyyat al-Bajjāna'' (''Bajjāna'' being the Arabic name for Pechina). History The origin of Almería is connected to the 9th-century establishment of the so-called Republic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Civil War
The Spanish Civil War () was a military conflict fought from 1936 to 1939 between the Republican faction (Spanish Civil War), Republicans and the Nationalist faction (Spanish Civil War), Nationalists. Republicans were loyal to the Left-wing politics, left-leaning Popular Front (Spain), Popular Front government of the Second Spanish Republic. The opposing Nationalists were an alliance of Falangism, Falangists, monarchists, conservatives, and Traditionalism (Spain), traditionalists led by a National Defense Junta, military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international Interwar period#Great Depression, political climate at the time, the war was variously viewed as class struggle, a War of religion, religious struggle, or a struggle between dictatorship and Republicanism, republican democracy, between revolution and counterrevolution, or between fascism and communism. The Nationalists won the war, which ended in early 1939, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full-load Displacement
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has three ...
