Valiant-class Submarine
The ''Valiant'' class were a class of nuclear-powered fleet submarines in service with the Royal Navy from the mid-1960s until 1994. They were the first fully British nuclear fleet submarine; the earlier used an American nuclear reactor. There were only two boats in the class, the first, ''Valiant'' (the nameship) commissioned in 1966 three years after ''Dreadnought'', and ''Warspite'' the following year. Both were built by Vickers at Barrow-in-Furness. Design The class were based on ''Dreadnought'', but were enlarged by 20 feet (6 m) and had a dived displacement of 4,900 tons compared to 4,000 tons. Improvements made since the original ''Dreadnought'' meant that they ran significantly quieter under main power, and also had a Paxman diesel-electric generator that could be used for silent running. In most other respects (outside the power plant), the ''Valiant''s were identical to ''Dreadnought''. According to former head of the Royal Corps of Naval Constructors R.J. Daniel, ...

Vickers Armstrong
Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977. History Vickers merged with the Tyneside-based engineering company Armstrong Whitworth, founded by William Armstrong, to become Vickers-Armstrongs. Armstrong Whitworth and Vickers had developed along similar lines, expanding into various military sectors and produced a whole suite of military products. Armstrong Whitworth were notable for their artillery manufacture at Elswick and shipbuilding at a yard at High Walker on the River Tyne. 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage and Wagon (MCCW); Metro Cammell. In 1935, before rearmament began, Vickers-Armstrongs was the third-largest manufacturing employ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paxman (engines)
Paxman is a major British brand of diesel engines. Ownership has changed on a number of occasions since the company's formation in 1865, and now the brand is part of MAN Diesel & Turbo. At its peak, the Paxman works covered and employed over 2,000 people. Early Paxman diesel engines (with "Comet" indirect injection cylinder heads, designed by Sir Harry Ricardo) carried the name Paxman Ricardo. History Davey Paxman Paxman was founded by James Noah Paxman, Henry and Charles Davey as Davey, Paxman & Davey, Engineers in 1865, later Davey, Paxman & Co. which became a limited company in 1898. In 1920 the company became a member of the Agricultural & General Engineers (AGE) combine. In 1932 AGE collapsed and Paxman emerged as Davey Paxman & Co (Colchester) Ltd. Davey, Paxman and Davey conducted business as general engineers and ironworkers. The company manufactured steam engines, boilers, agricultural machinery, and mill gearing. By the early 1870s the company was supplying mach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HMS Warspite (S103)
The latest HMS ''Warspite'' was the third of Britain's nuclear-powered submarines, and the second (and final) of the . After entering service in 1967 she collided with a Soviet submarine the following year. A mechanical failure associated with the submarine's nuclear reactor in 1991 led to the boat being laid up at HMNB Devonport where she awaits disposal. Operational history The second ''Valiant''-class submarine, to be called ''Warspite'', was ordered from Vickers-Armstrong's Barrow shipyard on 12 December 1962, and was laid down on 10 December 1963.Blackman 1971, p. 336. She was launched on 25 September 1965 by Mary Wilson, the wife of the then British Prime Minister Harold Wilson, and entered service on 18 April 1967. In October 1968 whilst following a Soviet boat identified as an Echo II-class submarine, ''Warspite'' collided with the stern and propellers of that boat. ''Warspite'' suffered damage to her fin but after surfacing to inspect damage was able to submerg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Valiant (S102)
The sixth and most recent HMS ''Valiant'' was the second of Britain's nuclear-powered submarines, and the first of the two-unit . Construction She was ordered on 31 August 1960 and laid down 22 January 1962 at Vickers-Armstrongs in Barrow-in-Furness. The basic design concept was to use the forward design of ''Dreadnought'' together with an aft end consisting of all British nuclear machinery based on the Dounreay prototype. She was launched on 3 December 1963 by Lady Thorneycroft, and finally entered service 18 July 1966. Operational history She was refitted in 1970, 1977 and 1989. In 1977 ''Valiant'' was trailing a Soviet submarine in the eastern Mediterranean when she suffered a salt water pipe leak, which flooded the reactor compartment with sea water. The reactor was shut down and the compartment pumped dry and after a clean-up of the compartment, the reactor was taken under power again. ''Valiant'' took part in the Falklands War in 1982, arriving in the war zone on ... [...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 ...

Falklands War
The Falklands War ( es, link=no, Guerra de las Malvinas) was a ten-week undeclared war between Argentina and the United Kingdom in 1982 over two British dependent territories in the South Atlantic: the Falkland Islands and its territorial dependency, South Georgia and the South Sandwich Islands. The conflict began on 2 April, when Argentina invaded and occupied the Falkland Islands, followed by the invasion of South Georgia the next day. On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with an Argentine surrender on 14 June, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders were killed during the hostilities. The conflict was a major episode in the protracted dispute over the territories' sovereignt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
