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] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

The Engineer (UK Magazine)
''The Engineer'' is a London-based monthly magazine and website covering the latest developments and business news in engineering and technology in the UK and internationally. History and description ''The Engineer'' was founded in January 1856. It was established by Edward Charles Healey, an entrepreneur and engineering enthusiast with financial interests in the railways whose friends included Robert Stephenson and Isambard Kingdom Brunel. The journal was created as a technical magazine for engineers. ''The Engineer'' began covering engineering including inventions and patents during a high point of British economic manufacturing power. In the 19th century it also published stock prices of raw materials. Together with the contemporary ''Engineering'' journal the work is considered a valuable historical resource for the study of British economic history. On 10 July 2012 the magazine announced its final print edition, the editor Jon Excell citing "increasing distribution and ...

Oriflamme F Destroyer
The Oriflamme (from Latin ''aurea flamma'', "golden flame"), a pointed, blood-red banner flown from a gilded lance, was the battle standard of the King of France in the Middle Ages. The oriflamme originated as the sacred banner of the Abbey of St. Denis, a monastery near Paris. When the oriflamme was raised in battle by the French royalty during the Middle Ages, most notably during the Hundred Years War, no prisoners were to be taken until it was lowered. Through this tactic they hoped to strike fear into the hearts of the enemy, especially the nobles, who could usually expect to be taken alive for ransom during such military encounters. In French, the term "''oriflamme''" has come to mean any banner with pointed ends, by association with the form of the original. Legendary origin The Oriflamme was mentioned in the eleventh-century ballad the ''Chanson de Roland'' (vv. 3093–5) as a royal banner, first called ''Romaine'' and then ''Montjoie''.
