United Kingdom Of Great Britain And Ireland
The United Kingdom of Great Britain and Ireland was a sovereign state in the British Isles that existed between 1801 and 1922, when it included all of Ireland. It was established by the Acts of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland into a unified state. The establishment of the Irish Free State in 1922 led to the remainder later being renamed the United Kingdom of Great Britain and Northern Ireland in 1927. The United Kingdom, having financed the European coalition that defeated France during the Napoleonic Wars, developed a large Royal Navy that enabled the British Empire to become the foremost world power for the next century. For nearly a century from the final defeat of Napoleon following the Battle of Waterloo to the outbreak of World War I, Britain was almost continuously at peace with Great Powers. The most notable exception was the Crimean War with the Russian Empire, in which actual hostilities were relatively li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Off Texel
The Battle off Texel, also known as the Action off Texel or the Action of 17 October 1914, was a naval battle off the coast of the Dutch island of Texel during the First World War. A British squadron, comprising one light cruiser and four destroyers on a routine patrol, encountered the German 7th Half Flotilla of torpedo boats which was ''en route'' to the British coast to lay mines. The British forces attacked and the outgunned German force attempted to flee and then fought a desperate and ineffective action against the British force, which sank all four German boats. The battle resulted in the loss of the German torpedo boat squadron and prevented the mining of busy shipping lanes, such as the mouth of the River Thames. The British had few casualties and little damage to their vessels. The battle influenced the tactics and deployments of the remaining German torpedo boat flotillas in the North Sea area, as the loss shook the faith of their commanders in the effectiveness of t ...

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea, epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind energy, wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Viking Age, Vikings' rise. The Hanseatic League, the Dutch Golden Age, Dutch Republic, and the Kingdom of Grea ...

Harwich Force
The Harwich Force originally called Harwich Striking Force was a squadron of the Royal Navy, formed during the First World War and based in Harwich. It played a significant role in the war. History After the outbreak of the First World War, a priority for the Royal Navy was to secure the approaches to the English Channel, to prevent elements of the German High Seas Fleet from breaking out into the Atlantic, or from interfering with British maritime trade and convoys to the continent. Most of the major fleet units of the Grand Fleet had dispersed to the navy's anchorage at Scapa Flow or to other North Eastern ports to monitor the northern route from the North Sea into the Atlantic. Consequently, a number of patrol flotillas were organised along the south and east coasts of England, with commands established at several of the major ports in the region. The Dover Patrol was based at Dover, consisting mostly of destroyers, while a number of pre-dreadnoughts and cruisers were ba ...

The Nore
The Nore is a long bank of sand and silt running along the south-centre of the final narrowing of the Thames Estuary, England. Its south-west is the very narrow Nore Sand. Just short of the Nore's easternmost point where it fades into the channels it has a notable point once marked by a lightship on the line where the estuary of the Thames nominally becomes the North Sea. A lit buoy today stands on this often map-marked divisor: between Havengore Creek in east Essex and Warden Point on the Isle of Sheppey in Kent. Until 1964 it marked the seaward limit of the Port of London Authority. As the sandbank was a major hazard for shipping coming in and out of London, in 1732 it received the world's first lightship. This became a major landmark, and was used as an assembly point for shipping. Today it is marked by Sea Reach No. 1 Buoy. The Nore is an anchorage, or open roadstead, used by the Royal Navy's North Sea Fleet, and to its local Command. It was the site of a notoriou ...

3rd Destroyer Flotilla
The British 3rd Destroyer Flotilla, also styled as Third Destroyer Flotilla, was a naval formation of the Royal Navy from 1909 to 1939 and again from 1945 to 1951. History In 1907 the Channel Fleet had a large Channel Flotilla of destroyers in February 1909 when it was divided to form the 1st and 3rd Destroyer Flotillas. From March 1909 to May 1912 the formation was part of the Nore Division, 3rd Division Home Fleet. In May 1912, the Home Fleet was split into the First Fleet, with ships in full commission, and the Second and Third Fleets, composed of ships partly manned and laid up in reserve respectively. The 3rd Destroyer Flotilla remained part of the First Fleet until July 1914. On the outbreak of the First World War, the First Fleet became the Grand Fleet, and the 3rd Destroyer Flotilla joined the newly formed Harwich Force. In the summer of 1915 it was renumbered the 9th Destroyer Flotilla. It was reformed again from March 1918 as part of the Grand Fleet till November 1918 ...

Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is t ...

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] |
Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individ ...

Vickers Elia Mine
Vickers was a British engineering company that existed from 1828 until 1999. It was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law, and soon became famous for casting church bells. The company went public in 1867, acquired more businesses, and began branching out into military hardware and shipbuilding. In 1911, the company expanded into aircraft manufacture and opened a flying school. They expanded even further into electrical and railway manufacturing, and in 1928 acquired an interest in the Supermarine. Beginning in the 1960s, various parts of the company were nationalised, and in 1999 the rest of the company was acquired by Rolls-Royce plc, who sold the defence arm to Alvis plc. The Vickers name lived on in Alvis Vickers, until the latter was acquired by BAE Systems in 2004 to form BAE Systems Land Systems. History Early history Vickers was formed in Sheffield as a steel foundry by Edward Vickers and his father-in-law George Naylor in ...
