German Cruiser Prinz Eugen
''Prinz Eugen'' () was an heavy cruiser, the third of a class of five vessels. She served with Nazi Germany's ''Kriegsmarine'' during World War II. The ship was laid down in April 1936, launched in August 1938, and entered service after the outbreak of war, in August 1940. She was named after Prince Eugene of Savoy, an 18th-century general in the service of Austria. She was armed with a main battery of eight guns and, although nominally under the limit set by the Anglo-German Naval Agreement, actually displaced over . ''Prinz Eugen'' saw action during Operation Rheinübung, an attempted breakout into the Atlantic Ocean with the battleship in May 1941. The two ships destroyed the British battlecruiser and moderately damaged the battleship in the Battle of the Denmark Strait. ''Prinz Eugen'' was detached from ''Bismarck'' during the operation to raid Allied merchant shipping, but this was cut short due to engine troubles. After putting into occupied France and undergoing r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bikini Atoll
Bikini Atoll ( or ; Marshallese: , , meaning "coconut place"), sometimes known as Eschscholtz Atoll between the 1800s and 1946 is a coral reef in the Marshall Islands consisting of 23 islands surrounding a central lagoon. After the Second World War, the atoll's inhabitants were forcibly relocated in 1946, after which the islands and lagoon were the site of 23 nuclear tests by the United States until 1958. The atoll is at the northern end of the Ralik Chain, approximately northwest of the capital Majuro. Three families were resettled on Bikini island in 1970, totaling about 100 residents, but scientists found dangerously high levels of strontium-90 in well water in May 1977, and the residents were carrying abnormally high concentrations of caesium-137 in their bodies. They were evacuated again in 1980. The atoll is occasionally visited today by divers and a few scientists, and is occupied by a handful of caretakers. Etymology The island's English name is derived f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deck (ship)
A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names. Structure The main purpose of the upper or primary deck is structural, and only secondarily to provide weather-tightness and support people and equipment. The deck serves as the lid to the complex box girder which can be identified as the hull. It resists tension, compression, and racking forces. The deck's scantling is usually the same as the topsides, or might be heavier if the deck is expected to carry heavier loa ...

Operation Cerberus
The Channel Dash (german: Unternehmen Zerberus, Operation Cerberus) was a German naval operation during the Second World War. (Cerberus), a three-headed dog of Greek mythology who guards the gate to Hades. A (German Navy) squadron comprising the two s, the heavy cruiser and their escorts was evacuated from Brest in Brittany to German ports. ''Scharnhorst'' and ''Gneisenau'' had arrived in Brest on 22 March 1941 after the success of Operation Berlin in the Atlantic. More raids were planned and the ships were refitted at Brest. The ships were a threat to Allied trans-Atlantic convoys and RAF Bomber Command attacked them from 30 March 1941. ''Gneisenau'' was hit on 6 April 1941 and ''Scharnhorst'' on 24 July 1941, after dispersal to La Pallice. In late 1941, Adolf Hitler ordered the (OKM; German Navy High Command) to plan an operation to return the ships to German bases against a British invasion of Norway. The short route up the English Channel was preferred to a detou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Denmark Strait
The Battle of the Denmark Strait was a naval engagement in the Second World War, which took place on 24 May 1941 between ships of the Royal Navy and the ''Kriegsmarine''. The British battleship and the battlecruiser fought the German battleship and the heavy cruiser , which were attempting to break out into the North Atlantic to attack Allied merchant shipping (Operation Rheinübung). Less than 10 minutes after the British opened fire, a shell from ''Bismarck'' struck ''Hood'' near her aft ammunition magazines. Soon afterwards, ''Hood'' exploded and sank within three minutes, with the loss of all but three of her crew. ''Prince of Wales'' continued to exchange fire with ''Bismarck'' but suffered serious malfunctions in her main armament. The British battleship had only been completed in late March 1941, and used new quadruple gun turrets that were unreliable. ''Prince of Wales'' soon broke off the engagement. The battle was a tactical victory for the Germans, but its impact w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Rheinübung
Operation Rheinübung ("Exercise Rhine") was the sortie into the Atlantic by the new German battleship and heavy cruiser on 18–27 May 1941, during World War II. This operation to block Allied shipping to the United Kingdom culminated with the sinking of ''Bismarck''. Background During both World Wars, the island of Britain was dependent upon huge numbers of merchant ships to bring in food and essential raw materials, and protecting this lifeline was one of the highest priorities for British forces. If this lifeline could be severed, the British Empire in Europe would have to either sue for peace; negotiate an armistice; or abandon the British Isles as a base of operations to blockade the sea approaches to Western Europe; giving Germany in effect, complete mastery of Western Europe, with no tactical base in Europe to oppose that control. Germany's naval leadership (under Admiral Erich Johann Albert Raeder) at the time firmly believed that defeat by blockade was achiev ...

Ship 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" (or "load lines"). A mer ...

Anglo-German Naval Agreement
The Anglo-German Naval Agreement (AGNA) of 18 June 1935 was a naval agreement between the United Kingdom and Germany regulating the size of the '' Kriegsmarine'' in relation to the Royal Navy. The Anglo-German Naval Agreement fixed a ratio whereby the total tonnage of the Kriegsmarine was to be 35% of the total tonnage of the Royal Navy on a permanent basis. It was registered in ''League of Nations Treaty Series'' on 12 July 1935. The agreement was renounced by Adolf Hitler on 28 April 1939. The Anglo-German Naval Agreement was an ambitious attempt on the part of both the British and the Germans to reach better relations, but it ultimately foundered because of conflicting expectations between the two countries. For Germany, the Anglo-German Naval Agreement was intended to mark the beginning of an Anglo-German alliance against France and the Soviet Union, whereas for Britain, the Anglo-German Naval Agreement was to be the beginning of a series of arms limitation agreements tha ...

General Officer
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of '' captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks. It has a NATO ran ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kriegsmarine
The (, ) was the navy of Germany from 1935 to 1945. It superseded the Imperial German Navy of the German Empire (1871–1918) and the inter-war (1919–1935) of the Weimar Republic. The was one of three official branches, along with the and the , of the , the German armed forces from 1935 to 1945. In violation of the Treaty of Versailles, the grew rapidly during German naval rearmament in the 1930s. The 1919 treaty had limited the size of the German navy and prohibited the building of submarines. ships were deployed to the waters around Spain during the Spanish Civil War (1936–1939) under the guise of enforcing non-intervention, but in reality supported the Nationalists against the Spanish Republicans. In January 1939, Plan Z, a massive shipbuilding program, was ordered, calling for surface naval parity with the British Royal Navy by 1944. When World War II broke out in September 1939, Plan Z was shelved in favour of a crash building program for submarines ( U-b ...

Heavy Cruiser
The heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in caliber, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser designs of the 1900s and 1910s, rather than the armored cruisers of the years before 1905. When the armored cruiser was supplanted by the battlecruiser, an intermediate ship type between this and the light cruiser was found to be needed—one larger and more powerful than the light cruisers of a potential enemy but not as large and expensive as the battlecruiser so as to be built in sufficient numbers to protect merchant ships and serve in a number of combat theaters.
