HMS Glatton (1914)
HMS ''Glatton'' and her sister ship were originally built as coastal defence ships for the Royal Norwegian Navy, as and respectively. She was requisitioned from Norway at the beginning of World War I, but was not completed until 1918 although she had been launched over three years earlier. On 16 September 1918, before she had even gone into action, she suffered a large fire in one of her 6-inch magazines, and had to be scuttled to prevent an explosion of her main magazines that would have devastated Dover. Her wreck was partially salvaged in 1926, and moved into a position in the northeastern end of the harbour where it would not obstruct traffic. It was subsequently buried by landfill underneath the current car ferry terminal. Background ''Bjørgvin'' was ordered by Norway in 1913 to supplement the older and classes of coastal defence ships. She would have been known in Norway as P/S ''Bjørgvin''; P/S stands for '' Panserskip'' ("armoured ship"), while ''Bjørgvin'' was ...

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 ...

Superfire
Superfiring armament is a naval military building technique in which two (or more) turrets are located in a line, one behind the other, with the second turret located above ("super") the one in front so that the second turret can fire over the first. This configuration meant that both forward or aft turrets could fire at any target within their sector, even when the target was in the same vertical plane as the turrets. History The history of large surface warships follow generic labels as battleships, and a further distinction between pre-dreadnoughts and dreadnoughts. The era of technical evolution occurred roughly from 1900 to 1945. Part of the technical evolution was driven by the need to compress as much large-gun firepower into the smallest space possible. In early designs, the large-caliber turrets were all located on the same plane firing to one side or the other. In firing ahead or to the rear, usually only the forward-most or rearmost turret could fire, especially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Yarrow
''Achillea millefolium'', commonly known as yarrow () or common yarrow, is a flowering plant in the family Asteraceae. Other common names include old man's pepper, devil's nettle, sanguinary, milfoil, soldier's woundwort, and thousand seal. The plant is native to temperate regions of the Northern Hemisphere in Asia, Europe, and North America. It has been introduced as a feed for livestock in New Zealand and Australia. Description ''Achillea millefolium'' is an erect, herbaceous, perennial plant that produces one to several stems in height, and has a spreading rhizomatous growth form. Leaves are evenly distributed along the stem, with the leaves near the middle and bottom of the stem being the largest. The leaves have varying degrees of hairiness (pubescence). The leaves are long, bipinnate or tripinnate, almost feathery, and arranged spirally on the stems. The leaves are cauline, and more or less clasping, being more petiolate near the base. The inflorescence has 4 to 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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] |
Bjørgvin
Bergen (), historically Bjørgvin, is a city and municipality in Vestland county on the west coast of Norway. , its population is roughly 285,900. Bergen is the second-largest city in Norway. The municipality covers and is on the peninsula of Bergenshalvøyen. The city centre and northern neighbourhoods are on Byfjorden, 'the city fjord', and the city is surrounded by mountains; Bergen is known as the "city of seven mountains". Many of the extra-municipal suburbs are on islands. Bergen is the administrative centre of Vestland county. The city consists of eight boroughs: Arna, Bergenhus, Fana, Fyllingsdalen, Laksevåg, Ytrebygda, Årstad, and Åsane. Trading in Bergen may have started as early as the 1020s. According to tradition, the city was founded in 1070 by King Olav Kyrre and was named Bjørgvin, 'the green meadow among the mountains'. It served as Norway's capital in the 13th century, and from the end of the 13th century became a bureau city of the Hanseatic Leagu ...

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] |
Dover
Dover () is a town and major ferry port in Kent, South East England. It faces France across the Strait of Dover, the narrowest part of the English Channel at from Cap Gris Nez in France. It lies south-east of Canterbury and east of Maidstone. The town is the administrative centre of the Dover District and home of the Port of Dover. Archaeological finds have revealed that the area has always been a focus for peoples entering and leaving Great Britain, Britain. The name derives from the River Dour that flows through it. In recent times the town has undergone transformations with a high-speed rail link to London, new retail in town with St James' area opened in 2018, and a revamped promenade and beachfront. This followed in 2019, with a new 500m Pier to the west of the Harbour, and new Marina unveiled as part of a £330m investment in the area. It has also been a point of destination for many illegal migrant crossings during the English Channel migrant crossings (2018-present) ...
