HMS Patriot (1916)
HMS ''Patriot'' was a that served in the British Royal Navy. The destroyer entered service in 1915 during the First World War and saw service with the Grand Fleet. Following the war, the destroyer was declared surplus and in 1920, the ship was transferred to the Royal Canadian Navy. Recommissioned as HMCS ''Patriot'', the destroyer was used primarily as a training ship. ''Patriot'' was taken out of service in 1927, sold for scrap in 1929 and broken up. Design and description ''Patriot'' was a Thornycroft M-class destroyer that displaced and was long overall with a beam of and a draught of . The ship was propelled by three shafts driven by Brown-Curtis turbines powered by three Yarrow boilers creating . This gave the ship a maximum speed of . The destroyer carried of fuel oil.Gardiner and Gray, pp. 79–80 The destroyer was armed with three quick-firing (QF) /45 calibre Mark IV guns in single mounts. The No.2 4-inch gun was placed on a bandstand, unlike earlier M-clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steam Turbine
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] |
Action Off Lerwick
The action off Lerwick (, "Lerrick") was a naval engagement on 17 October 1917 fought in the North Sea during the First World War. The German light, minelaying cruisers and attacked a westbound convoy of twelve colliers and other merchant ships and their escorts, part of the regular Scandinavian convoy. The two escorting destroyers and nine neutral Scandinavian ships were sunk off Shetland, Scotland. Admiralty code breakers had uncovered the call signs of ''Bremse'' and ''Brummer'' and by direction finding knew that they had sailed from Wilhelmshaven to (Lister Deep) north of Sylt but an operation as far north as the Scandinavian convoy collier route was not anticipated by the British naval commanders because the Admiralty failed promptly to pass on the information. Both of the British destroyer commanders were commended for their bravery, though some members of the Admiralty felt that by leaving the convoy to engage a superior enemy force, they had left the merchant ships ope ...

Emden
Emden () is an independent city and seaport in Lower Saxony in the northwest of Germany, on the river Ems. It is the main city of the region of East Frisia and, in 2011, had a total population of 51,528. History The exact founding date of Emden is unknown, but it has existed at least since the 8th century. Older names for Emden are Setutanda, Amuthon, Embda, Emda, Embden and Embderland. Town privilege and the town's coat of arms, the ''Engelke up de Muer'' (The Little Angel on the Wall) was granted by Emperor Maximilian I in 1495. In the 16th century, Emden briefly became an important centre for the Protestant Reformation under the rule of Countess Anna von Oldenburg who was determined to find a religious "third way" between Lutheranism and Catholicism. In 1542 she invited the Polish noble John Laski (or ''Johannes a Lasco'') to become pastor of a Protestant church at Emden; and for 7 years he continued to spread the new religion around the area of East Frisia.

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...

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 some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
14th Destroyer Flotilla
The14th Destroyer Flotilla, or Fourteenth Destroyer Flotilla, was a naval formation of the British Royal Navy from April 1916 to 11 February 1919 and again from 1 June 1940 to January 1944. History World War One The flotilla was first established in April 1916 and operated with the Grand Fleet until November 1918. It was disbanded on 11 February 1919. Second World War The flotilla was reformed 1 January 1940 allocated to the Mediterranean Fleet until 28 January 1943. It was part of Force C at the Battle of Cape Matapan, 27 to 29 March 1941.

Ceremonial Ship Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Admiralty M-class Destroyer
The M class, more properly known as the Admiralty M class, were a class of 85 destroyers built for the Royal Navy of United Kingdom that saw service during World War I. All ships were built to an identical – Admiralty – design, hence the class name. 18 other vessels which were officially included within the 'M' class were built to variant designs by three specialist builders – 10 by Yarrow, 6 by Thornycroft (who also built another 6 to the standard Admiralty design), and 2 by Hawthorn Leslie; these are covered in other articles. The Admiralty design was based on the preceding L class but modified to produce an increase in speed by approximately . All ships built to the Admiralty design had three identical narrow, circular funnels (this did not apply to the 18 ships built by the specialist yards). Ships of the pre-war (1913–14) Programme Six vessels were built under the 1913–14 Naval Programme. These differed from the wartime vessels by being 1,010 tons full load, with ...

Bandstand
A bandstand (sometimes music kiosk) is a circular, semicircular or polygonal structure set in a park, garden, pier, or indoor space, designed to accommodate musical bands performing concerts. A simple construction, it both creates an ornamental focal point and also serves acoustic requirements while providing shelter for the changeable weather, if outdoors. In form bandstands resemble ornamental European garden gazebos modeled on outdoor open-sided pavilions found in Asian countries from early times. Origins During the 18th and 19th centuries this type of performance building was found in the fashionable pleasure gardens of London and Paris where musicians played for guests dining and dancing. They were later built in public spaces in many countries as practical amenities for outdoor entertainment. Many bandstands in the United Kingdom originated in the Victorian era as the British brass band movement gained popularity. Smaller bandstands are often not much more than gaze ...
