Last Battle Of The Battleship Bismarck
The last battle of the German battleship ''Bismarck'' took place in the Atlantic Ocean approximately west of Brest, France, on 26–27 May 1941 between the and naval and air elements of the British Royal Navy. Although it was a decisive action between capital ships, it has no generally accepted name. It was the culmination of Operation Rheinübung where the attempt of two German ships to disrupt the Atlantic convoys to the United Kingdom failed with the scuttling of the ''Bismarck''. The last battle consisted of four main phases. The first phase late on 26 May consisted of air strikes by torpedo bombers from the British aircraft carrier , which disabled ''Bismarck''s steering gear, jammed her rudders in a turning position and prevented her escape. The second phase was the shadowing and harassment of ''Bismarck'' during the night of 26/27 May by British and Polish destroyers, with no serious damage to any ship. The third phase on the morning of 27 May was an attack by the Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Rheinübung
Operation Rheinübung () was the last sortie into the Atlantic by the new German battleship and heavy cruiser on 18–27 May 1941, during World War II. This operation aimed to disrupt Allied shipping to the United Kingdom as the previously successful Operation Berlin had done. After ''Bismarck'' had sunk HMS ''Hood'' during the Battle of the Denmark Strait (24 May), it culminated with the sinking of the ''Bismarck'' (27 May), while ''Prinz Eugen'' escaped to port in occupied France. From that point on, Germans would rely only on U-boats to wage the Battle of the Atlantic. Background During both World Wars, Britain relied heavily on merchant ships to import food, fuel, and raw materials, such things were crucial both for civilian survival and the military effort. Protecting this lifeline was a high priority for British forces, as its disruption would significantly weaken the British economy and its military capabilities, and Britain might be forced to negotiate peace, se ...

Map Rheinuebung
A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. History Maps have been one of the most important human inventions for millennia, allowing humans t ...

4th Destroyer Flotilla
The British 4th Destroyer Flotilla or Fourth Destroyer Flotilla, was a naval formation of the Royal Navy from August 1909 to July 1951. History In 1907 the Home Fleet had a large formation of destroyers called the Home Fleet Flotilla of destroyers, Between February and June 1909 it was divided to form the 2nd and 4th Destroyer Flotillas. Between 1909 and 1912 it was part of the Home Fleet - 3rd Division at Portsmouth. From 1912 to August 1914 it was reassigned and operating with the 1st Fleet. At the start of World War One the flotilla was reassigned to the new Grand Fleet and was engaged at the Battle of Jutland it remained with the GF until September 1916 when it was transferred to the Humber Force that was receiving shore support from the Humber Station till December 1916. The flotilla was next allocated to the Portsmouth Command until July 1917. After being ordered to leave Portsmouth it was reassigned to the Commander-in-Chief, Devonport where it remained till November ...

Triangulate
In trigonometry and geometry, triangulation is the process of determining the location of a point by forming triangles to the point from known points. Applications In surveying Specifically in surveying, triangulation involves only angle measurements at known points, rather than measuring distances to the point directly as in trilateration; the use of both angles and distance measurements is referred to as triangulateration. In computer vision Computer stereo vision and optical 3D measuring systems use this principle to determine the spatial dimensions and the geometry of an item. Basically, the configuration consists of two sensors observing the item. One of the sensors is typically a digital camera device, and the other one can also be a camera or a light projector. The projection centers of the sensors and the considered point on the object's surface define a (spatial) triangle. Within this triangle, the distance between the sensors is the base ''b'' and must be known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belt Armour
Belt armor is a layer of heavy metal armor plated onto or within the outer hulls of warships, typically on battleships, battlecruisers and cruisers, and aircraft carriers. The belt armor is designed to prevent projectiles from penetrating to the heart of a warship. When struck by an artillery shell or underwater torpedo, the belt armor either absorbs the impact and explosion with its sheer thickness and strength, or else uses sloping to redirect the projectile and its blast downwards. Typically, the main armor belt covers the warship from its main deck down to some distance below the waterline. If, instead of forming the outer hull, the armor belt is built inside the hull, it is installed at a sloped angle for improved protection, as described above. The torpedo bulkhead Frequently, the main belt's armor plates were supplemented with a torpedo bulkhead spaced several meters behind the main belt, designed to maintain the ship's watertight integrity even if the main belt w ...

Eugene Esmonde
Lieutenant Commander Eugene Esmonde, (1 March 1909 – 12 February 1942) was a distinguished Irish pilot in the Fleet Air Arm who was posthumously awarded the Victoria Cross (VC), the highest award for gallantry in the face of the enemy awarded to members of Commonwealth forces. Esmonde earned this award while in command of a torpedo bomber squadron in the Second World War - in an action known as Operation Fuller, the 'Channel Dash’. Early life Esmonde was born on 1 March 1909 in Thurgoland, Yorkshire, near Barnsley. His mother, Eily O’Sullivan, was his father's second wife. Dr John Joseph Esmonde (1862–1915) had married her in 1904, after his first wife died in 1901. Dr. Esmonde was an Irish Catholic, a former Irish MP, who was in general practice in Yorkshire. Esmonde had six natural siblings (including a twin brother) and six half-siblings - three male, three female - from his father's first marriage to Rose McGuinness. The natural siblings were: Owen, Donal, John Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
825 Naval Air Squadron
825 Naval Air Squadron is a Royal Navy Fleet Air Arm Naval Air Squadron which was re-commissioned on 10 October 2014 and currently flies the AgustaWestland Wildcat HMA2. It was a carrier-based squadron that was formed on 8 October 1934 from the aircraft and personnel of 824 Naval Air Squadron. It operated in most of the theatres of the Second World War, carrying out a number of attacks on prominent German warships, including the battleship in the Atlantic and the pocket battleships and and heavy cruiser during their Channel Dash. The squadron also saw action in later conflicts, including the Korean War and the Falklands War. History Pre-war history 825 Squadron's first assignment after commissioning was to board the aircraft carrier for service on the China Station. This was short-lived, and by January 1935 both the squadron and the carrier were in the Mediterranean. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biplane
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. The term is als ...

Fairey Swordfish
The Fairey Swordfish is a retired biplane torpedo bomber, designed by the Fairey Aviation Company. Originating in the early 1930s, the Swordfish, nicknamed "Stringbag", was principally operated by the Fleet Air Arm of the Royal Navy. It was also used by the Royal Air Force (RAF), as well as several overseas operators, including the Royal Canadian Air Force (RCAF) and the Royal Netherlands Navy. It was initially operated primarily as a fleet attack aircraft. During its later years, the Swordfish was increasingly used for Anti-submarine warfare, anti-submarine and Trainer (aircraft), training duties. The type was in frontline service throughout the World War II, Second World War. Despite being obsolescent, the Swordfish achieved some spectacular successes during the war, including sinking one battleship and damaging two others belonging to the ''Regia Marina'' (the Italian navy) during the Battle of Taranto, and the Last battle of Bismarck, famous attack on the German battleship ...

Swordfish On HMS Victorious Before Strike On Bismarck
The swordfish (''Xiphias gladius''), also known as the broadbill in some countries, are large, highly migratory predatory fish characterized by a long, flat, pointed bill. They are the sole member of the family Xiphiidae. They are a popular sport fish of the billfish category. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of , and exceptionally up to depths of 2,234 m. They commonly reach in length, and the maximum reported is in length and in weight. Taxonomy and etymology The swordfish is named after its long pointed, flat bill, which resembles a sword. The species name, ''Xiphias gladius'', derives from Greek (''xiphias'', "swordfish"), itself from (''xiphos'', "sword") and from Latin ("sword"). This makes it superficially similar to other billfish such as marlin, but u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Finisterre
Cape Finisterre (, also ; ; ) is a rock-bound peninsula on the west coast of Galicia, Spain. In Roman times it was believed to be an end of the known world. The name Finisterre, like that of Finistère in France, derives from the Latin , meaning "end of the earth". It is sometimes said to be the westernmost point of the Iberian Peninsula. However, Cabo da Roca in Portugal is about farther west and thus the westernmost point of continental Europe. Even in Spain Cabo Touriñán is 124 metres (135 yards) farther west. Monte Facho is the name of the mountain on Cape Finisterre, which has a peak that is above sea level. A prominent lighthouse is at the top of Monte Facho. The seaside town of Fisterra is nearby. The Artabri were an ancient Gallaecian Celtic tribe that once inhabited the area. Geography Cape Finisterre has several beaches, including O Rostro, Arnela, Mar de Fora, Langosteira, Riveira, and Corbeiro. Many of the beaches are framed by steep cliffs leading down ...

Scapa Flow
Scapa Flow (; ) is a body of water in the Orkney Islands, Scotland, sheltered by the islands of Mainland, Graemsay, Burray,S. C. George, ''Jutland to Junkyard'', 1973. South Ronaldsay and Hoy. Its sheltered waters have played an important role in travel, trade and conflict throughout the centuries. Vikings anchored their longships in Scapa Flow more than a thousand years ago. It was the United Kingdom's chief naval base during the First and Second World wars, but the facility was closed in 1956. Since the scuttling of the German fleet after World War I, its wrecks and their marine habitats form an internationally acclaimed diving location. Scapa Flow hosts an oil port, the Flotta oil terminal. In good weather, its roadstead (water of moderate conditions) allows ship-to-ship transfers of crude oil product. The world's first ship-to-ship transfer of liquefied natural gas (LNG) took place in Scapa Flow in 2007 transferring 132,000m³ of LNG. This occurred in 2007 by ...
