Swiftsure Class Submarine
The ''Swiftsure'' class was a class of nuclear-powered fleet submarines in service with the Royal Navy from the early 1970s until 2010. Six boats were built and commissioned. ''Swiftsure'' was decommissioned in 1992 due to damage suffered to her pressure hull during trials. followed in 2004 after defence cuts caused a reduction in the size of the Royal Navy submarine fleet. was decommissioned in January 2006, with following on 12 September 2006. was decommissioned on 26 September 2008. The remaining boat in the class, , was decommissioned in December 2010. The six boats of the class were not replaced, although the seven boats of the successor ''Trafalgar''-class submarines are in the process of being replaced by seven boats of the ''Astute''-class submarines. A few were upgraded with the capability to launch Tomahawk cruise missiles in addition to their original armaments of torpedoes, mines and anti-ship missiles. They were also the first class of Royal Navy submar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers Shipbuilding And Engineering
Vickers Shipbuilding and Engineering, Ltd (VSEL) was a shipbuilding company based at Barrow-in-Furness, Cumbria in northwest England that built warships, civilian ships, submarines and armaments. The company was historically the Naval Construction Works of Vickers Armstrongs and has a heritage of building large naval warships and armaments. Through a complicated history the company's shipbuilding division is now BAE Systems Submarine Solutions and the armaments division is now part of BAE Systems Land & Armaments. History The company was founded in 1871 by James Ramsden as the Iron Shipbuilding Company, but its name was soon changed to Barrow Shipbuilding Company. In 1897, ''Vickers & Sons'' bought the ''Barrow Shipbuilding Company'' and its subsidiary the ''Maxim Nordenfelt Guns and Ammunition Company'', becoming ''Vickers, Sons and Maxim, Limited''. The shipyard at Barrow became the Naval Construction & Armaments Company. In 1911 the company was renamed ''Vickers Ltd'', and ...

Pump-jet
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs. The design also incorporates an intake to provide water to the pump and a nozzle to direct the flow of water out of the pump.http://www.hamiltonmarine.co.nz/includes/files_cms/file/JetTorque%2008.pdf Design A pump-jet works by having an intake (usually at the bottom of the hull) that allows water to pass underneath the vessel into the engines. Water enters the pump through this inlet. The pump can be of a centrifugal design for high speeds, or an axial flow pump for low to medium speeds. The water pressure inside the inlet is increased by the pump and forced backwards through a nozzle. With the use of a ''reversing bucket'', reverse thrust can also be achieved for faring backwards, quickly and withou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1982 Invasion Of The Falkland Islands
The Invasion of the Falkland Islands ( es, Invasión de las Islas Malvinas), code-named Operation Rosario (), was a military operation launched by Argentine forces on 2 April 1982, to capture the Falkland Islands, and served as a catalyst for the subsequent Falklands War. The Argentines mounted amphibious landings and the invasion ended with the surrender of Falkland Government House. Defence Governor Rex Hunt was informed by the British Government of a possible Argentine invasion on 1 April 1982. At 3:30 pm that day he received a telegram from the Foreign and Commonwealth Office stating: Forces involved The Governor summoned the two senior Royal Marines of Naval Party 8901 to Government House in Stanley to discuss the options for defending the Falklands. He said during the meeting, "Sounds like the buggers mean it." Major Mike Norman was given overall command of the Marines due to his seniority, while Major Gary Noott became the military advisor to Governor Hunt. The ...

Falkland Islands
The Falkland Islands (; es, Islas Malvinas, link=no ) is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and about from Cape Dubouzet at the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland, and 776 smaller islands. As a British overseas territory, the Falklands have internal self-governance, but the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley on East Falkland. Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times, the islands have had French, British, Spanish, and Argentine settlements. Britain reasserted its rule in 1833, but Argentina maintains its claim to the islands. In April 1982, Argentine military forces invaded the islands. British a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Splendid (S106)
HMS ''Splendid'' was a Royal Navy nuclear-powered fleet submarine of the . From commissioning in 1979 to her decommission in 2004 she took part in many operations involving British forces around the globe. Construction HMS ''Splendid'' was ordered on 26 May 1976 as the sixth and last submarine of the ''Swiftsure'' class. The submarine was laid down at Vickers Shipbuilding Groups Barrow-in-Furness shipyard on 23 November 1977 and was launched on 5 October 1979 by Lady Eberle, wife of Admiral Sir James Eberle, then Commander-in-Chief Fleet. ''Splendid'' commissioned on 21 March 1981 under the command of Commander R. C. Lane-Nott. Operational history Her first major conflict came in 1982 during the Falklands War when Argentinian forces invaded the British Falkland Islands. ''Splendid'' was one of the first submarines to reach the islands, arriving mid-April, after sailing from Faslane. Unlike , ''Splendid'' did not directly engage Argentinian forces, however she shadowed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Spartan (S105)
HMS ''Spartan'' was a nuclear-powered fleet submarine of the Royal Navy's . ''Spartan'' was launched on 7 April 1978 by Lady Lygo, wife of Admiral Sir Raymond Lygo. The boat was built by Vickers Limited Shipbuilding Group (now a division of BAE Systems) at Barrow-in-Furness in Cumbria, England. She was decommissioned in January 2006. Operational history ''Spartan'' was ordered to sail south for the Falkland Islands two days before the Argentine invasion of the islands on 30 March 1982. ''Spartan'' was the first vessel to arrive in the islands and began to enforce a maritime exclusion zone imposed by the British. Shortly after, ''Spartan'' sighted Argentine merchant shipping mining the harbour at Stanley, but was not ordered to attack. This was partly due to British concerns about escalating the war too early, but also to avoid scaring off more lucrative targets such as the Argentine aircraft carrier . On 1 May, ''Spartan'' was marking ''Veinticinco de Mayo'', from just out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Sceptre (S104)
The fifth HMS ''Sceptre'' is a built by Vickers in Barrow-in-Furness. She was launched in 1976, with a bottle of cider against her hull.''Sceptre's Apple Bye'', Navy News, August 2010, p. 11. She was commissioned on 14 February 1978, by Lady Audrey White. She was the tenth nuclear fleet submarine to enter service with the Royal Navy. She was decommissioned on 10 December 2010, at which time she was the oldest commissioned vessel in the Royal Navy still available for service; in total around 1,500 men served aboard during her commission. In theory, she is replaced by the first in service, HMS ''Astute''. Service Collision with a Soviet submarine ''Sceptre'' has suffered several severe accidents in her career. On 23 May 1981 she collided with a Soviet submarine ('' K-211'') and her reactor's protection systems would have performed an automatic emergency shutdown (scrammed the reactor), but her captain ordered the safety mechanisms overridden (battleshort enabled).

HMS Superb (S109)
HMS ''Superb'' was a nuclear-powered fleet submarine of the serving in the Royal Navy. ''HMS Superb'' was built by Vickers Shipbuilding Group, now a division of BAE Systems Submarine Solutions. ''Superb'' was launched on 30 November 1974 at Barrow-in-Furness, Cumbria and commissioned into the Royal Navy on 13 November 1976. After being damaged in May 2008 in the Red Sea, she returned to HMNB Devonport where she was decommissioned slightly ahead of schedule on 26 September 2008. Operations She was the first British submarine to visit the Arctic Ocean and sail under the polar ice caps. During the Falklands War, ''Superb'' was spotted sailing from Gibraltar, which prompted press speculation that she was sailing to the South Atlantic to enforce a maritime exclusion zone. In fact, only was sailing south at that time but the speculation was useful to promote the apparent threat of the Royal Navy in the South Atlantic and was not corrected by the Navy or Ministry of Defence. ...

HMS Sovereign (S108)
HMS ''Sovereign'' was a nuclear-powered fleet submarine of the Royal Navy. Construction Construction of the boat began on 18 September 1970. She was launched on 17 February 1973 and commissioned on 11 July 1974. Operational history In 1976, ''Sovereign'' played a role in Operation Brisk; the submarine surfaced at the geographical North Pole on 20 October 1976 as part of the exercise, testing navigational systems and equipment performance in low temperatures. HMS ''Sovereign'' actually surfaced on 21 October 1976 about halfway between the Geographic North Pole and the northern tip of Ellesmere island. Brisk was a coordinated operation between the Royal Navy and the Canadian Forces Maritime Proving & Evaluation Unit (MP&EU) from CFB Summerside, Prince Edward Island. MP&EU was in a six-year project of evaluating airborne remote sensing devices including a SLAR, Satellite laser ranging, ILRS and a Laser Profilometer which were all used to do imaging during ''Sovereign''s through ...

Barrow-in-Furness
Barrow-in-Furness is a port town in Cumbria, England. Historically in Lancashire, it was incorporated as a municipal borough in 1867 and merged with Dalton-in-Furness Urban District in 1974 to form the Borough of Barrow-in-Furness. In 2023 the borough will merge with Eden and South Lakeland districts to form a new unitary authority; Westmorland and Furness. At the tip of the Furness peninsula, close to the Lake District, it is bordered by Morecambe Bay, the Duddon Estuary and the Irish Sea. In 2011, Barrow's population was 56,745, making it the second largest urban area in Cumbria after Carlisle. Natives of Barrow, as well as the local dialect, are known as Barrovian. In the Middle Ages, Barrow was a small hamlet within the parish of Dalton-in-Furness with Furness Abbey, now on the outskirts of the town, controlling the local economy before its dissolution in 1537. The iron prospector Henry Schneider arrived in Furness in 1839 and, with other investors, opened the Furness Railwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any pennants ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
