O And P-class Destroyer
The O and P class was a class of destroyers of the British Royal Navy. Ordered in 1939, they were the first ships in the War Emergency Programme, also known as the 1st and 2nd Emergency Flotilla, respectively. They served as convoy escorts in World War II, and some were subsequently converted to fast second-rate anti-submarine frigates in the 1950s. Design The O and P class were based on the hull and machinery of the preceding J class, but with more sheer forward to counter the poor riding qualities of the Js. These ships used the Fuze Keeping Clock HA Fire Control Computer.Destroyer Weapons of WW2, Hodges/Friedman, O class The O-class ships were built in two groups of four. The first group had 4.7 inch guns. They were in low-angle mounts which could elevate to only 40 degrees, and were additionally fitted with a 4 inch anti-aircraft gun in place of one set of torpedo tubes. The second group had guns in high-angle mounts and were fitted to act as minelayers; they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Cashmore Ltd
John Cashmore Ltd (also known as J Cashmore, or simply as Cashmore's or other derivations) was a company operating largely in Newport, Monmouthshire, Wales. It became best known for ship breaking and scrapping redundant British railway locomotives. History The company was founded in 1872 by a member of the Cashmore family in Horseley Heath, Staffordshire. While eventually the large part of the business was in Newport, with a business address at the Old Town Dock, the headquarters was in Great Bridge, Tipton. Scrapping of steam locomotives from the LMR, ER and WR, also took place at Gold's Hill, Great Bridge. The shipbreaking business was closed in October 1976, and the remaining business was incorporated into the Gynwed Group. Ship breaking It ran a ship breaking business on the banks of the River Usk, which had a very high tide enabling large vessels to be moved upstream. It scrapped many ex-Royal Navy ships including the following: * (Destroyer - 1914) * (Destroyer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Brown & Company
John Brown and Company of Clydebank was a Scottish Naval architecture, marine engineering and shipbuilding firm. It built many notable and world-famous ships including , , , , , and the ''Queen Elizabeth 2 (ship), Queen Elizabeth 2''. At its height, from 1900 to the 1950s, it was one of the most highly regarded, and internationally famous, shipbuilding companies in the world. However thereafter, along with other UK shipbuilders, John Brown's found it increasingly difficult to compete with the emerging shipyards in Eastern Europe and the far East. In 1968 John Brown's merged with other Clydeside shipyards to form the Upper Clyde Shipbuilders consortium, but that collapsed in 1971. The company then withdrew from shipbuilding but its engineering arm remained successful in the manufacture of industrial gas turbines. In 1986 it became a wholly owned subsidiary of Trafalgar House (company), Trafalgar House, which in 1996 was taken over by Kvaerner. The latter closed the Clydebank en ...

Fairfield Shipbuilding And Engineering Company
The Fairfield Shipbuilding and Engineering Company, Limited was a Scottish shipbuilding company in the Govan area on the Clyde in Glasgow. Fairfields, as it is often known, was a major warship builder, turning out many vessels for the Royal Navy and other navies through the First World War and the Second World War. It also built many transatlantic liners, including record-breaking ships for the Cunard Line and Canadian Pacific, such as the Blue Riband-winning sisters RMS ''Campania'' and RMS ''Lucania''. At the other end of the scale, Fairfields built fast cross-channel mail steamers and ferries for locations around the world. These included ships for the Bosporus crossing in Istanbul and some of the early ships used by Thomas Cook for developing tourism on the River Nile. John Elder & Co and predecessors Millwright Randolph & Elliott Charles Randolph founded the company as Randolph & Co. He had been an apprentice at the Clyde shipyard of Robert Napier, and at William ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Denny And Brothers
William Denny and Brothers Limited, often referred to simply as Denny, was a Scottish shipbuilding company. History The shipbuilding interests of the Denny family date back to William Denny (born 1779), for whom ships are recorded being built in Dumbarton as far back as 1811 such as the sailing sloop ''Alpha''.) By 1823 the company name had changed to William Denny & Son. The first ship it built under this name was the paddle steamer ''Superb''. From 1845 the company became Denny Brothers (this being William jnr, Alexander and Peter), and in 1849 the firm was reconstituted as William Denny & Brothers, this being William, James and Peter Denny. Although the Denny yard was situated near the junction of the River Clyde and the River Leven, the yard was on the Leven. The founder developed the company's interests in ship owning and operation with interests in the British & Burmese Steam Navigation Company, the Irrawaddy Flotilla Company and La Platense Flotilla. The Company built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Barents Sea
The Battle of the Barents Sea was a World War II naval engagement on 31 December 1942 between warships of the German Navy (''Kriegsmarine'') and British ships escorting convoy JW 51B to Kola Inlet in the USSR. The action took place in the Barents Sea north of North Cape, Norway. The German raiders' failure to inflict significant losses on the convoy infuriated Hitler, who ordered that German naval strategy would henceforth concentrate on the U-boat fleet rather than surface ships. Background JW 51B Convoy JW 51B comprised fourteen merchant ships carrying war materials to the USSR — some 202 tanks, 2,046 vehicles, 87 fighters, 33 bombers, of fuel, of aviation fuel and just over of other supplies. They were protected by the destroyers , , , , and ; the s and ; the minesweeper ; and trawlers and . The escort commander was Captain Robert Sherbrooke RN (flag in ''Onslow''). The convoy sailed in the dead of winter to preclude attacks by German aircraft, like those that d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers
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.

Anti-aircraft
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...

Fuze Keeping Clock
The Fuze Keeping Clock (FKC) was a simplified version of the Royal Navy's High Angle Control System analogue fire control computer. It first appeared as the FKC MkII in destroyers of the 1938 ,''Tribal Class Destroyers'', Hodges, p. 27 while later variants were used on sloops, frigates, destroyers, aircraft carriers and several cruisers. The FKC MkII was a non-tachymetric anti-aircraft fire control computer. It could accurately engage targets with a maximum speed of . Operation The FKC received vertical reference information from a ''Gyro Level Corrector'' and aircraft altitude, range, direction, and speed input information from the ''Rangefinder-Director'', and output to the guns the elevation and deflection data needed to hit the target, along with the correct fuze timing information, so that the shells fired would explode in the vicinity of the target aircraft. Most guns controlled by the FKC had ''Fuze Setting Pedestals'' or ''Fuze Setting Trays'' where the correct fuze timin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
J, K And N-class Destroyer
The J, K and N class consisted of 24 destroyers built for the Royal Navy beginning in 1938. They were a return to a smaller vessel, with a heavier torpedo armament, after the that emphasised guns over torpedoes. The ships were built in three flotillas or groups, each consisting of eight ships with names beginning with "J", "K" and "N". The flag superior of the pennant numbers changed from "F" to "G" in 1940. The ships were modified throughout their wartime service, particularly their anti-aircraft (AA) guns; they were also fitted with radar. Design history The design was intended as a smaller follow-on from the preceding Tribal class, and incorporated one radical new idea that was a departure from all previous Royal Navy destroyer designs. That was the adoption of a two boiler room layout. This reduced hull length and allowed for a single funnel, both reducing the profile and increasing the arcs of fire of the light anti-aircraft (AA) weapons. However, this also increased vu ...

Anti-submarine
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
