Oscarsborg Fortress
Oscarsborg Fortress ( no, Oscarsborg festning) is a coastal fortress in the Oslofjord, close to the small town of Drøbak in Viken county, Norway. The best known part is situated on two small islets. The main artillery batteries are on the island Håøya and smaller batteries on the mainland to the west and east in the fjord and was military territory until 2003 when it was made a publicly available resort island. The fortress is best known for sinking the German heavy cruiser '' Blücher'' on 9 April 1940. In 2014, Oscarsborg Fortress was given protected status. Early history The narrows at Drøbak, called '' Drøbaksundet'', is a natural point for the naval defence of Oslo, the capital of Norway. The first defences were constructed during the reign of Christian IV of Denmark and Norway and were ready in 1644. The fortifications were however not involved in battle during the Hannibal War.National Fortresses of NorwayHistorical overview of Oscarsborg Fortress After the war ...

28 Cm MRK L/35
The 28 cm MRK L/35 was a German naval gun that was used in World War I as the primary armament of the Brandenburg-class pre-dreadnought battleships. It also saw use as a Coastal-defense gun during World War II. Design The 28 cm MRK L/35 gun was a built-up gun made from three layers of reinforcing hoops. It used a cylindro-prismatic horizontal sliding breech, but unlike later Krupp guns it didn't use a metallic cartridge case. Instead, it used separate loading bagged charges and projectiles. The four ships of the Brandenburg-class had a slightly unusual arrangement for their primary armament. Although the primary armament consisted of six 28 cm guns in three twin gun turrets that all fired the same ammunition, the fore and aft turrets had 28 cm MRK L/40 guns, while the amidships turret had 28 cm MRK L/35 guns due to space constraints. The ships did not have centralized fire control and each gun type had different ballistics. The L/35 guns had a muzzle velocity ...

Oscarshall
Oscarshall Palace is a ''maison de plaisance'' located in the small fjord Frognerkilen on Bygdøy in Oslo, Norway. History The palace was built from 1847 to 1852 by the Danish architect Johan Henrik Nebelong on commission from King Oscar I and Queen Joséphine of Norway and Sweden. In 1881, King Oscar II opened the palace to the public as a museum. The palace, with its secondary buildings and surrounding park, is considered to be one of the finest examples of neo-Gothic architecture in Norway and is one of the country's most important embodiments of the National Romantic style which was popular in Norway during the period. The interior was wholly constructed and decorated by Norwegian artists and artisans. The walls of the dining hall are decorated with paintings by Joachim Frich and Adolph Tidemand, while the decoration and furniture in the drawing room evokes the style of the old Norwegian guildhall. Oscarshall was sold by King Carl IV to the Norwegian state in 1863. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian IV Of Denmark
Christian IV (12 April 1577 – 28 February 1648) was King of Denmark and Norway and Duke of Holstein and Schleswig from 1588 until his death in 1648. His reign of 59 years, 330 days is the longest of Danish monarchs and Scandinavian monarchies. A member of the House of Oldenburg, Christian began his personal rule of Denmark in 1596 at the age of 19. He is remembered as one of the most popular, ambitious, and proactive Danish kings, having initiated many reforms and projects. Christian IV obtained for his kingdom a level of stability and wealth that was virtually unmatched elsewhere in Europe. He engaged Denmark in numerous wars, most notably the Thirty Years' War (1618–1648), which devastated much of Germany, undermined the Danish economy, and cost Denmark some of its conquered territories. He rebuilt and renamed the Norwegian capital Oslo as ''Christiania'' after himself, a name used until 1925. Early years Birth and family Christian was born at Frederiksborg ...

Robert Whitehead
Robert Whitehead (3 January 1823 – 14 November 1905) was an English engineer who was most famous for developing the first effective self-propelled naval torpedo. Early life He was born in Bolton, England, the son of James Whitehead, a cotton-bleacher, and his wife Ellen Whitehead née Swift. He trained as an engineer and draughtsman, and attended the Mechanics' Institute, Manchester. His first professional employment was at a shipyard in Toulon, France, for Philip Taylor & Sons, and then as a consultant engineer in Milan, Italy. He then moved to Trieste, on the Adriatic coast of Austria. Whitehead's work in Trieste was noticed by the owners of ''Fonderia Metalli'', a metal foundry in the nearby city of Fiume (today Rijeka, Croatia). In 1856, Whitehead became manager of the company, and changed its name to ''Stabilimento Tecnico di Fiume'' (STF). STF produced marine steam boilers and engines, which were the most modern products of that era. The Austrian Navy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trinitrotoluene
Trinitrotoluene (), more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene, is a chemical compound with the formula C6H2(NO2)3CH3. TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts. History TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not recognized for three decades, mainly because it was too difficult to detonate because it was less sensitive than alternatives. Its explosive properties were first discovered in 1891 by another German chemist, Carl Häussermann. TNT can be safely poured when liquid into shell cases, and is so insensitive t ...

Bergen
Bergen (), historically Bjørgvin, is a city and municipality in Vestland county on the west coast of Norway. , its population is roughly 285,900. Bergen is the second-largest city in Norway. The municipality covers and is on the peninsula of Bergenshalvøyen. The city centre and northern neighbourhoods are on Byfjorden, 'the city fjord', and the city is surrounded by mountains; Bergen is known as the "city of seven mountains".

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 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. 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 the submarine into the sea at the ambien ...

Hurum
Hurum was a municipality in Buskerud county, Norway. As of 1 January 2020 Hurum has merged with the municipalities of Røyken and Asker to form the new Asker Municipality located in the newly formed Viken county. The administrative centre of the municipality is the village Sætre. The municipality of Hurum was established on 1 January 1838 (see formannskapsdistrikt). The small village of Holmsbu was granted town status in 1847, but it did not become a municipality of its own. It lost its town status on 1 January 1964. Hurum was once suggested as the location for the new national airport of Norway. The plan was, however, abandoned, due to fears of too much fog in Hurum, and the main airport is now situated at Gardermoen in Akershus. Etymology Name The Old Norse form of the name was ''Húðrimar''. The meaning of the first element ''(Húð)'' is unknown and the last element is the plural form of ''rimi'' which means "ridge". Coat-of-arms The coat-of-arms is from modern times. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krupp
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, is notable for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars. Starting from the Thirty Years' War until the end of the Second World War, it produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The dynasty began in 1587 when trader Arndt Krupp moved to Essen and joined the merchants' guild. He bought and sold real estate, and became one of the city's richest men. His descendants produced small guns during the Thirty Years' War and eventually acquired fulling mills, coal mines and an iron forge. During the Napoleonic Wars, Friedrich ...

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 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 large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large ships without the need of large guns, though ...
