HMS Gorgon (1914)
HMS ''Gorgon'' and her sister ship were two monitors originally built as coastal defence ships for the Royal Norwegian Navy, as HNoMS ''Nidaros'' and respectively, by Armstrong Whitworth at Elswick. She was purchased from Norway at the beginning of the First World War, but was not completed until 1918 although she had been launched over three years earlier. She engaged targets in Occupied Flanders for the last several months of the war and fired the last shots of the war against such targets on 15 October 1918. She was used as a target ship after several attempts to sell her had fallen through before being sold for scrap in 1928. Background ''Nidaros'' was ordered by Norway in 1913 to supplement the older and classes of coastal defense ships. She would have been known in Norway as P/S ''Nidaros''; P/S stands for '' Panserskip'' ("armoured ship"), while ''Nidaros'' was the old name for the Norwegian city of Trondheim. However, when the First World War broke out, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armstrong Whitworth
Sir W G Armstrong Whitworth & Co Ltd was a major British manufacturing company of the early years of the 20th century. With headquarters in Elswick, Newcastle upon Tyne, Armstrong Whitworth built armaments, ships, locomotives, automobiles and aircraft. The company was founded by William Armstrong in 1847, becoming Armstrong Mitchell and then Armstrong Whitworth through mergers. In 1927, it merged with Vickers Limited to form Vickers-Armstrongs, with its automobile and aircraft interests purchased by J D Siddeley. History In 1847, the engineer William George Armstrong founded the Elswick works at Newcastle, to produce hydraulic machinery, cranes and bridges, soon to be followed by artillery, notably the Armstrong breech-loading gun, with which the British Army was re-equipped after the Crimean War. In 1882, it merged with the shipbuilding firm of Charles Mitchell to form Armstrong Mitchell & Company and at the time its works extended for over a mile (about 2 km) along th ...

Royal Norwegian Navy
The Royal Norwegian Navy ( no, Sjøforsvaret, , Sea defence) is the branch of the Norwegian Armed Forces responsible for naval operations of Norway. , the Royal Norwegian Navy consists of approximately 3,700 personnel (9,450 in mobilized state, 32,000 when fully mobilized) and 70 vessels, including 4 heavy frigates, 6 submarines, 14 patrol boats, 4 minesweepers, 4 minehunters, 1 mine detection vessel, 4 support vessels and 2 training vessels. It also includes the Coast Guard. This navy has a history dating back to 955. From 1509 to 1814, it formed part of the navy of Denmark-Norway, also referred to as the "Common Fleet". Since 1814, the Royal Norwegian Navy has again existed as a separate navy. In Norwegian, all its naval vessels since 1946 bear ship prefix "KNM", Kongelig Norske Marine (which accurately translates to Royal Norwegian Navy/Naval vessel). In English, they are permitted still to be ascribed prefix "HNoMS", meaning "His/Her Norwegian Majesty's Ship" ("HNMS" could b ...

Watertube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Triple Expansion
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a s ...

Anti-torpedo Bulge
The anti-torpedo bulge (also known as an anti-torpedo blister) is a form of defence against naval torpedoes occasionally employed in warship construction in the period between the First and Second World Wars. It involved fitting (or retrofitting) partially water-filled compartmentalized sponsons on either side of a ship's hull, intended to detonate torpedoes, absorb their explosions, and contain flooding to damaged areas within the bulges. Application Essentially, the bulge is a compartmentalized, below the waterline sponson isolated from the ship's internal volume. It is part air-filled, and part free-flooding. In theory, a torpedo strike will rupture and flood the bulge's outer air-filled component while the inner water-filled part dissipates the shock and absorbs explosive fragments, leaving the ship's main hull structurally intact. Transverse bulkheads within the bulge limit flooding to the damaged area of the structure. The bulge was developed by the British Director of N ...

Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Through their history they served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets. Origins and development The first small steam-powered cruisers were built for the British Royal Navy with HMS ''Mercury'' launched in 1878. Such second and third class protected cruisers evolved, gradually becoming faster, better armed and better protected. Germany took a lead in small crui ...

Breastwork Monitor
A breastwork monitor was a modification of the monitor, a warship which was first built in the United States in 1861, designed by John Ericsson and distinguished by the first rotating gun turret, designed by Theodore Timby. The modified design known as a breastwork monitor was introduced by Sir Edward Reed, the Chief Constructor of the Royal Navy between 1863 and 1870. The original monitors were very stable, and difficult to damage by gunfire, because of their very low freeboard. This, however, caused them to behave, some said, as a "half-tide rock", with the ever-present risk of being swamped in a sea should water gain access to the interior through hatches, turret bases or other openings in the deck. Reed proposed to overcome this risk by the addition of an armoured breastwork. This was an armoured superstructure of moderate height ( in ), centrally placed on the ship and containing within its armoured circumference the gun turrets, bridge, funnels and all other upper deck ...

Elswick, Tyne And Wear
Elswick ( ) is a district and electoral ward of the city and metropolitan borough of Newcastle upon Tyne, England, 1.9 miles west of the city centre, bordering the River Tyne. Historically in Northumberland, Elswick became part of Newcastle upon Tyne in 1835. Elswick is home to the Newcastle Utilita Arena; and Newcastle College, with approximately 45,000 students. History In Roman times the Vallum, a defensive barrier behind Hadrian's Wall, reached its easternmost limit in Elswick. The Wall itself carried on as far as Wallsend. The township of Elswick had originally formed part of the Barony of Bolam and was owned by Tynemouth Priory from 1120-1539, with a fishery present on the site. One of the earliest references to the coal mining industry of the north east occurs in 1330, when it was recorded that the Prior of Tynemouth let a colliery, called Heygrove, at "Elstewyke" for a rent of £5 per year. Elswick Colliery had 3 pits working from 1860 onwards. Elswick was owned by t ... [...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] |
Trondheim
Trondheim ( , , ; sma, Tråante), historically Kaupangen, Nidaros and Trondhjem (), is a city and municipality in Trøndelag county, Norway. As of 2020, it had a population of 205,332, was the third most populous municipality in Norway, and was the fourth largest urban area. Trondheim lies on the south shore of Trondheim Fjord at the mouth of the River Nidelva. Among the major technology-oriented institutions headquartered in Trondheim are the Norwegian University of Science and Technology (NTNU), the Foundation for Scientific and Industrial Research (SINTEF), and St. Olavs University Hospital. The settlement was founded in 997 as a trading post, and it served as the capital of Norway during the Viking Age until 1217. From 1152 to 1537, the city was the seat of the Catholic Archdiocese of Nidaros; it then became, and has remained, the seat of the Lutheran Diocese of Nidaros, and the site of the Nidaros Cathedral. It was incorporated in 1838. The current municipalit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nidaros
Nidaros, Niðarós or Niðaróss () was the medieval name of Trondheim when it was the capital of Norway's first Christian kings. It was named for its position at the mouth (Old Norse: ''óss'') of the River Nid (the present-day Nidelva). Although the capital was later moved to Oslo, Nidaros remained the centre of Norway's spiritual life until the Protestant Reformation. The Archdiocese of Nidaros was separated from Lund (in Scania) by the papal legate Nicholas Breakspeare in 1152, and the shrine to Saint Olaf in Nidaros Cathedral was Northern Europe's most important pilgrimage site during the Middle Ages. Archbishop Olav Engelbrektsson led Norway in its attempted resistance against the Danish Reformation, and was forced into exile by King Christian III in 1537. The archdiocese was abolished and replaced with a Lutheran diocese. Pre-Reformation The Christianization of Norway was begun by Haakon the Good (d. 961) and was continued by Olaf Trygvesson (d. 1000) and Saint Olaf ...

Coastal Defence Ship
Coastal defence ships (sometimes called coastal battleships or coast defence ships) were warships built for the purpose of coastal defence, mostly during the period from 1860 to 1920. They were small, often cruiser-sized warships that sacrificed speed and range for armour and armament. They were usually attractive to nations that either could not afford full-sized battleships or could be satisfied by specially designed shallow-draft vessels capable of littoral operations close to their own shores. The Nordic countries and Thailand found them particularly appropriate for their island-dotted coastal waters. Some vessels had limited blue-water capabilities; others operated in rivers. The coastal defence ships differed from earlier monitors by having a higher freeboard and usually possessing both higher speed and a secondary armament; some examples also mounted casemated guns (monitors' guns were almost always in turrets). They varied in size from around 1,500 tons to 8,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
