Yarrow M-class Destroyer
The Yarrow M class was a class of ten destroyers built for the Royal Navy that saw service during World War I. They were generally similar to the standard , but were instead designed by the builder, Yarrow & Company. Generally, they had two instead of three shafts, as well as two funnels and a straight stern, with the bridge set well back from the forecastle. The first trio were two knots faster than the Admiralty M type, despite less installed power and one less shaft; the installed power was increased for the later vessels.

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 unatte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbines
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QF 4 Inch Naval Gun Mk IV, XII, XXII
The QF 4-inch gun Mk IVMk IV = Mark 4. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. This was the fourth model of 4-inch QF naval gun. Variants Mk XII = Mark 12, Mk XXII = Mark 22. was the main gun on most Royal Navy and British Empire destroyers in World War I. It was introduced in 1911 as a faster-loading light gun successor to the BL 4 inch Mk VIII gun. Of the 1,141 produced, 939 were still available in 1939.Campbell, ''Naval Weapons of WWII'', p.59. Mk XII and Mk XXII variants armed many British interwar and World War II submarines. Mk IV gun Mk IV armed many British destroyers and some cruisers in World War I. It was used to arm merchant ships in World War II. The guns armed the following warships : * ''Forward''-class scout cruisers as re-gunned in 1911 * ''Sentinel''-class scout cruisers as re-gunned 1911-1912 * ''Pathfinder''-class scout cruisers as re-gunned 1911-1912 * ''Adventure''-class scout cruisers as re-gunned 19 ...

QF 2 Pounder Naval Gun
The 2-pounder gun, officially the QF 2-pounder ( QF denoting "quick firing") and universally known as the pom-pom, was a British autocannon, used as an anti-aircraft gun by the Royal Navy.British military of the period traditionally denoted smaller guns in terms of the approximate weight of the standard projectile, rather than by its bore diameter, which in this case was 40 mm. References to 40-mm anti-aircraft guns invariably mean the Bofors gun, while references to 2-pounder anti-aircraft guns mean this gun. The name came from the sound that the original models make when firing. This QF 2-pounder was not the same gun as the Ordnance QF 2-pounder, used by the British Army as an anti-tank gun and a tank gun, although they both fired , projectiles. Predecessors - Boer War and the Great War QF 1 pounder The first gun to be called a pom-pom was the 37 mm Nordenfelt-Maxim or "QF 1-pounder" introduced during the Second Boer War, the smallest artillery piece of that war.

British 21 Inch Torpedo
There have been several British 21-inch (533 mm) torpedoes used by the Royal Navy since their first development just before the First World War. Torpedoes of 21 inch calibre were the largest torpedoes in common use in the RN. They were used by surface ships and submarines rather than aircraft, which used smaller 18-inch torpedoes. Mark I The first British 21-inch torpedo came in two lengths, "Short" at , and "Long" at . The explosive charge was of gun cotton increased later to . Mark II The Mark II, chiefly used by destroyers, entered service in 1914. Apart from some older British ships, it was used with the old US (destroyers-for-bases deal) Town-class destroyers provided to the UK during the early part of the Second World War. The running speed was reduced from (over 3,000 yards) for better reliability. The Mark II*, an improved Mark II, was used by battleships and battlecruisers. A wet heater design, it could run for at . Mark IV From 1912, used by destr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Class
A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, is a nuclear aircraft carrier (ship type) of the (ship class). In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in a class often have names linked by a common factor: e.g. s' names all begin with T (, , ); and s are named after American battles (, , , ). Ships of the same class may be referred to as sister ships. Naval ship class naming conventions Overview The name of a naval ship class is most commonly the name of the lead ship, the first ship commissioned or built of its design. ...

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 ... [...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 List of wars and anthropogenic disasters by death toll, 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 Ocean, 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 in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 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 French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...

Jane's Fighting Ships
''Jane's Fighting Ships'' by Janes Information Services is an annual reference book of information on all the world's warships arranged by nation, including information on ships' names, dimensions, armaments, silhouettes and photographs, etc. Each edition describes and illustrates warships of different national naval and paramilitary forces, providing data on their characteristics. The first issue was illustrated with Jane's own ink sketches--photos began to appear with the third volume in 1900. The present title was adopted in 1905. It was originally published by Fred T. Jane in London in 1898 as ''Jane's All the World's Fighting Ships'', in order to assist naval officers and the general public in playing naval wargames. Its success eventually launched a number of military publications carrying the name "Jane's". It is a unit of Jane's Information Group, which is now owned by IHS. Ten early editions of Jane's (those of 1898, 1905-06, 1906-07, 1914, 1919, 1924, 1931, 1939, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kite Balloon
A kite balloon is a tethered balloon which is shaped to help make it stable in low and moderate winds and to increase its lift. It typically comprises a streamlined envelope with stabilising features and a harness or yoke connecting it to the main tether and a second harness connected to an observer's basket. Kite balloons are able to fly in higher winds than ordinary round balloons which tended to bob and spin in windy conditions.Ege, 1973, pp.128–129 They were extensively used for military observation during World War I and similar designs were used for anti-aircraft barriers, as barrage balloons in both world wars. Design and development Developed in Germany from 1893 by ''Parseval'' and ''Sigsfeld'', the main component of a kite balloon is its tubular-shaped envelope, similar to that of a non-rigid airship, giving it its British and French nicknames of "sausage". This was inclined at a nose up angle to about 30–40° from the horizontal, which resulted in it producing som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
