HNLMS Draak
HNLMS ''Draak'' (Dutch: ''Draak'') was a monitor (Dutch: ''rammonitor 1e klasse''), built by the '' Rijkswerf'' at Amsterdam for the Royal Netherlands Navy in the late 1870s. Design and description In early 1875, the Dutch Navy in the home waters consisted of 4 ram turret ships, 10 monitors and 16 gunboats. All but two of these were armed with 23 cm muzzle loading guns. This is probably why the Dutch preferred to stick with the 23 cm gun. When England finally admitted the superiority of breech-loading guns over muzzle-loading guns, the Dutch government followed suit. The switch from 23 cm muzzle-loaders to 28 cm breech-loaders would have strong effects on the design of Dutch monitors. The contract for the preceding monitor ''Luipaard'', ordered in July 1875, only called for a change to breech-loaders, not to an overall redesign. The result was a monitor nearly identical to the previous ten monitors, but armed with 1 breech-loading 28 cm gun instead of two 23 cm muzzle-loaders. '' ...

Roadstead
A roadstead (or ''roads'' – the earlier form) is a body of water sheltered from rip currents, spring tides, or ocean swell where ships can lie reasonably safely at anchor without dragging or snatching.United States Army technical manual, TM 5-360. Port Construction and Rehabilitation'. Washington: United States. Government Printing Office, 1964. It can be open or natural, usually estuary-based, or may be created artificially. In maritime law, it is described as a "known general station for ships, notoriously used as such, and distinguished by the name". Definition A roadstead can be an area of safe anchorage for ships waiting to enter a port, or to form a convoy. If sufficiently sheltered and convenient, it can be used for the transshipment of goods, stores, and troops, either separately or in combination. The same applies in transfers to and from shore by Lighter (barge), lighters. In the days of sailing ships, some voyages could only easily be made with a change in wind dir ...

Naval Ships Of The Netherlands
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applicati ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag Inclusion (mineral), inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to structural failure, failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welding, forge welded, but is more difficult to welding, weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is Carbon steel#Mild or low-carbon steel, mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krupp
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, is notable for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars. Starting from the Thirty Years' War until the end of the Second World War, it produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The dynasty began in 1587 when trader Arndt Krupp moved to Essen and joined the merchants' guild. He bought and sold real estate, and became one of the city's richest men. His descendants produced small guns during the Thirty Years' War and eventually acquired fulling mills, coal mines and an iron forge. During the Napoleonic Wars, Friedrich Kr ...

Werkspoor
Werkspoor N.V. was the shortened, and later the official name of the Nederlandsche Fabriek van Werktuigen en Spoorwegmaterieel. It was a Dutch machine factory, known for rolling stock, (ship) steam engines, and diesel engines. It was a successor of the company Van Vlissingen en Dudok van Heel, later named Koninklijke Fabriek van Stoom- en andere Werktuigen. In 1954 Werkspoor was merged with Stork. Founded as Nederlandsche Fabriek van Werktuigen en spoorwegmaterieel In March 1890 the predecessor of Werkspoor asked for an automatic stay. After many years of heavy losses the financial world lacked confidence in this predecessor, the Koninklijke Fabriek van Stoom- en andere Werktuigen. What was needed was a radical restructuring and new leadership. Because of the national and city interest, authorities intervened to bring this about. The mayor of Amsterdam G. van Tienhoven succeeded in engaging C.T. Stork (owner of the machine factory Stork) in the operation and to provide a good ...

Zuiderzee
The Zuiderzee or Zuider Zee (; old spelling ''Zuyderzee'' or ''Zuyder Zee'') was a shallow bay of the North Sea in the northwest of the Netherlands, extending about 100 km (60 miles) inland and at most 50 km (30 miles) wide, with an overall depth of about 4 to 5 metres (13–16 feet) and a coastline of about 300 km (200 miles). It covered . Its name is Dutch for "southern sea", indicating that the name originates in Friesland, to the north of the Zuiderzee (cf. North Sea). In the 20th century the majority of the Zuiderzee was closed off from the North Sea by the construction of the Afsluitdijk, leaving the mouth of the inlet to become part of the Wadden Sea. The salt water inlet changed into a fresh water lake now called the IJsselmeer (IJssel Lake) after the river that drains into it, and by means of drainage and polders, an area of some was reclaimed as land. This land eventually became the province of Flevoland, with a population of nearly 400,000 (2011) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
