Mermaid-class Destroyer
Two ''Mermaid''-class destroyers served with the Royal Navy during the First World War. They were three-funnelled turtle-backed destroyers with the usual Hawthorn funnel tops. Built in 1896–1898, and were launched by R. & W. Hawthorn, Leslie & Company from their Hebburn-on-Tyne shipyard. Their Thornycroft boilers produced 6,100 hp to given them the required and they were armed with the standard 12-pounder gun 12-pounder gun or 12-pdr, usually denotes a gun which fired a projectile of approximately 12 pounds. Guns of this type include: *12-pounder long gun, the naval muzzle-loader of the Age of Sail *Canon de 12 de Vallière, French cannon of 1732 *Cano ... and two torpedo tubes. They carried a complement of 63 officers and men. In 1913 the pair - like all other surviving three-funnelled destroyers of the "30-knotter" group - were reclassed as s. The almost identical ships built subsequently at the same yard differed only by having Yarrow boilers. References ... [...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] |
Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

QF 12 Pounder 12 Cwt Naval Gun
The QF 12-pounder 12-cwt gun (abbreviated as Q.F. 12-pdr. (12-cwt.)Gun drill for Q.F. 12-pdr. (12-cwt.) gun (Land service) 1925 the War Office, 1925) was a common, versatile caliber, calibre naval gun introduced in 1894 and used until the middle of the 20th century. It was produced by Armstrong Whitworth, Elswick Ordnance Company, Elswick and used on Royal Navy warships, exported to allied countries, and used for land service. In British service "12-pounder" was the rounded value of the projectile weight, and "12 cwt (hundredweight)" was the weight of the barrel and breech, to differentiate it from other "12-pounder" guns. As the Type 41 3-inch (7.62 cm)/40 it was used on most early battleships and cruisers of the Imperial Japanese Navy, though it was commonly referred ...

British 18 Inch Torpedo
There have been a number of 18-inch torpedoes in service with the United Kingdom. These have been used on ships of the Royal Navy and aircraft of both the Fleet Air Arm and Royal Air Force, while Royal Navy surface ships and submarines use 21-inch torpedoes. The British "18-inch" torpedoes were in diameter, beginning with the "Fiume" Whitehead torpedo of 1890. 45 cm "Fiume" (Whitehead) torpedo First introduced into British service in 1894. * Year : about 1888 * Weight : * Length : * Warhead : wet gun-cotton * Performance : for * Propulsion : Compressed air Mark V Used on the River-class and 1905 Tribal-class destroyers. * Year : about 1899 * Weight : * Warhead : including pistol * Propulsion : Compressed air Mark VI Used on destroyers of the early 1900s. * Year : about 1904 * Performance : for or for * Propulsion : Compressed air Mark VII and VII* Introduced on the 1908 members of the 1905 Tribal class destroyers.

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] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawthorn Leslie And Company
R. & W. Hawthorn, Leslie and Company, Limited, usually referred to as Hawthorn Leslie, was a shipbuilder and locomotive manufacturer. The company was founded on Tyneside in 1886 and ceased building ships in 1982. History The company was formed by the merger of the shipbuilder A. Leslie and Company in Hebburn with the locomotive works of R and W Hawthorn at St. Peter's in Newcastle upon Tyne in 1886. The company displaced its locomotive manufacturing interests in 1937 to Robert Stephenson and Company, which became ''Robert Stephenson and Hawthorns Ltd.'' Perhaps the most famous ship built by the Company was HMS ''Kelly'', launched in 1938 and commanded by Lord Louis Mountbatten. In 1954, the shipbuilding and marine engine activities were put into separate subsidiaries, Hawthorn Leslie (Shipbuilders) Ltd. and Hawthorn Leslie (Engineers) Ltd. In 1968 the Company's shipbuilding interests were merged with that of Swan Hunter and the Vickers Naval Yard to create Swan Hunter & Tyne ...

Thornycroft Boiler
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler. The fundamental characteristic of the "three-drum" design is the arrangement of a steam drum above two water drums, in a triangular layout. Water tubes fill in the two sides of this triangle between the drums, and the furnace is in the centre. The whole assembly is then enclosed in a casing, leading to the exhaust flue. Firing can be by either coal or oil. Many coal-fired boilers used multiple firedoors and teams of stokers, often from both ends. Development Development of the three-drum boiler began in the late 19th century, with the demand from naval ships that required high power and a compact boiler. The move to water-tube boilers had already begun, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
