Evertsen-class Coastal Defence Ship
The ''Evertsen'' class or ''Kortenaer'' class was a class of coastal defense ships of the Royal Netherlands Navy. The class comprised ''Evertsen'', ''Piet Hein'' and ''Kortenaer''.Jane (1900), p. 158. History The protection of the Dutch East Indies came into the spotlight at the end of the nineteenth century. Many countries began expanding their battle fleets. In 1887, two medium-sized Chinese battleships became operational and were considered superior to the Dutch defence. This led to a reassessment of the defence of the Dutch East Indies. In April 1892, the foundations for modernisation were formulated by a committee consisting of three officers J.H. Kromhout, F.J. Haver Droeze and G. Kruys. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rijkswerf (Amsterdam)
The Rijkswerf (Dutch: ''State shipyard'') in Amsterdam was a Dutch shipyard that build a significant amount of warships for the Royal Netherlands Navy. Predecessors of the Rijkswerf Shipyard of the Amsterdam Admiralty In the time of the Dutch republic naval affairs were handled by 5 local admiralties. The Admiralty of Amsterdam was the most important of these. The First Anglo-Dutch War proved the need for a professional navy. On 12 August 1655, the admiralty therefore got the entire western strip of Kattenburg island for the construction of an arsenal and ship yard. The arsenal was quickly constructed on the southern extremity of Kattenburg island in 1656. It was called 's Lands Zeemagazijn and now houses the National Maritime Museum. The rest of Kattenburg island stretches north along the Kattenburgerstraat. On the west side of this street the former yard is still enclosed by a very long seventeenth century building and a long old wall that reaches almost to the north end of ...

Rear Admiral
Rear admiral is a senior naval flag officer rank, equivalent to a major general and air vice marshal and above that of a commodore and captain, but below that of a vice admiral. It is regarded as a two star " admiral" rank. It is often regarded as a two-star rank with a NATO code of OF-7. The term originated in the days of naval sailing squadrons and can trace its origins to the Royal Navy. Each naval squadron was assigned an admiral as its head, who commanded from the centre vessel and directed the squadron's activities. The admiral would in turn be assisted by a vice admiral, who commanded the lead ships that bore the brunt of a battle. In the rear of the squadron, a third admiral commanded the remaining ships and, as this section was considered to be in the least danger, the admiral in command of it was typically the most junior. This has continued into the modern age, with rear admiral the most junior admiralty of many navies. In most European navies, the equivalent ran ...

Flushing, Netherlands
Vlissingen (; zea, label= Zeelandic, Vlissienge), historically known in English as Flushing, is a municipality and a city in the southwestern Netherlands on the former island of Walcheren. With its strategic location between the Scheldt river and the North Sea, Vlissingen has been an important harbour for centuries. It was granted city rights in 1315. In the 17th century Vlissingen was a main harbour for ships of the Dutch East India Company (VOC). It is also known as the birthplace of Admiral Michiel de Ruyter. Vlissingen is mainly noted for the yards on the Scheldt where most of the ships of the Royal Netherlands Navy (''Koninklijke Marine'') are built. Geography The municipality of Vlissingen consists of the following places: * City: Vlissingen * Villages: Oost-Souburg, Ritthem, and West-Souburg * Hamlet: Groot-Abeele History The fishermen's hamlet that came into existence at the estuary of the Schelde around AD 620 has grown over its 1,400-year history into th ...

Barbette
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. ...

Harvey Armor
Harvey armor was a type of steel naval armor developed in the early 1890s in which the front surfaces of the plates were case hardened. The method for doing this was known as the Harvey process, and was invented by the American engineer Hayward Augustus Harvey. This type of armor was used in the construction of capital ships until superseded by Krupp armor in the late 1890s. The Harvey United Steel Company was a steel cartel whose chairman was Albert Vickers. The year 1894 would see the ten main producers of armor plate, including Vickers, Armstrong, Krupp, Schneider, Carnegie and Bethlehem Steel, form the Harvey Syndicate. Predecessors Before the appearance of compound armor in the 1880s, armor plating was made from uniform homogeneous iron or steel plates backed by several inches of teak to absorb the shock of projectile impact. Compound armor appeared in the mid-1880s and was made from two different types of steel, a very hard but brittle high-carbon steel fro ...

Naval Armour
Naval armour refers to the various protections schemes employed by warships, and is distinguished from other kinds of armour. Naval sailing ships have had protection from weaponry since at least ancient times, when Greek and Roman warships used simple cladding. As weapons evolved and became more destructive, naval armour became an important part of warships. Korean and European ships began to use some iron plating in the 1500s. The first ironclad warship was created in 1859, and the pace of armour advancement accelerated quickly thereafter. The emergence of battleships around the turn of the 20th century saw ships become increasingly large and well armoured. Vast quantities of heavily armoured ships were used during the World Wars, and were crucial in the outcome. The emergence of guided missiles in the last part of the 20th century has greatly reduced the utility of armor, and most modern warships are now only lightly armored. Naval armour consists of many different designs, dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reciprocating Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is i ...

Dutch Caribbean
The Dutch Caribbean (historically known as the Dutch West Indies) are the territories, colonies, and countries, former and current, of the Dutch Empire and the Kingdom of the Netherlands in the Caribbean Sea. They are in the north and south-west of the Lesser Antilles archipelago. Currently, it comprises the constituent countries of Aruba, Curaçao and Sint Maarten (CAS islands), and the special municipalities of Bonaire, Sint Eustatius and Saba (BES islands). The term "Dutch Caribbean" is sometimes also used for the Caribbean Netherlands, an entity consisting of the three special municipalities forming part of the constituent country of the Netherlands since 2010. The Dutch Caribbean has a population of 337,617 as of January 2019. History The islands in the Dutch Caribbean were, from 1815, part of the colonies Curaçao and Dependencies (1815–1828) or Sint Eustatius and Dependencies (1815–1828), which were merged with the colony of Suriname (not considered par ...

Squadron (naval)
A squadron, or naval squadron, is a significant group of warships which is nonetheless considered too small to be designated a fleet. A squadron is typically a part of a fleet. Between different navies there are no clear defining parameters to distinguish a squadron from a fleet (or from a flotilla), and the size and strength of a naval squadron varies greatly according to the country and time period. Groups of small warships, or small groups of major warships, might instead be designated flotillas by some navies according to their terminology. Since the size of a naval squadron varies greatly, the rank associated with command of a squadron also varies greatly. Before 1864 the entire fleet of the Royal Navy was divided into three squadrons, the red, the white, and the blue. Each Royal Navy squadron alone was more powerful than most national navies. Today, a squadron might number three to ten vessels, which might be major warships, transport ships, submarines, or small craf ...

Damen Schelde Naval Shipbuilding
Damen Naval is a Dutch shipyard, and a continuation of the Koninklijke Maatschappij De Schelde, responsible for a number of ships used by the Royal Netherlands Navy. It is owned by the Damen Group. Damen Naval is situated in Vlissingen. History The company was founded October 8, 1875, as the ''NV Koninklijke Maatschappij De Schelde'' (KMS) after shipbuilder Arie Smit had taken over the ''Marine Etablissement'' the wharf owned by the Dutch navy. Besides shipbuilding and repair, the company also builds machines, engines, steam turbines, airplanes, and light-metal products. Koninklijk is a royal title granted by the Dutch Crown. In 1965 the company merged with the NV Rotterdamsche Droogdok Maatschappij (RDM) and the NV Motorenfabriek Thomassen of De Steeg, which resulted in the founding, on March 4, 1966, of the Rijn-Schelde Machinefabrieken en Scheepswerven NV (RSMS). Pressured by the Dutch government the Verolme Verenigde Scheepswerven NV was added, and this was the start of Rijn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
