RML 7-inch Armstrong Gun
The RML 7-inch Armstrong Gun was a rifled muzzle loading gun. It was an export version of the British Royal Navy's RML 7-inch gun. The RML 7-inch Armstrong Gun was produced by William Armstrong's Elswick Ordnance Company. Context The Armstrong gun In 1859 the United Kingdom adopted rifled breechloading guns, the so called Armstrong guns, designed by William Armstrong, 1st Baron Armstrong. Armstrong then became engineer of rifled ordnance. The Armstrong guns would be produced at the Royal Works at Woolwich as well as at the new Elswick Ordnance Company founded in Newcastle on 1 January 1859. The latter was founded with government support. It was to guarantee the separation of Armstrong's interests as a civil servant and his interests as a machine builder. For the navy, the Armstrong breechloaders came in 40-pounder (4.75 inch), 70-pounder (6.4 inch) and 110-pounder (7 inch) caliber. In combat and trials, the guns up to and including 40-pounder caliber, proved to be very suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Gun
Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for naval gunfire support, shore bombardment and anti-aircraft roles. The term generally refers to tube-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines. Origins The idea of ship-borne artillery dates back to the classical era. Julius Caesar indicates the use of ship-borne catapults against Britons ashore in his ''Commentarii de Bello Gallico''. The dromons of the Byzantine Empire carried catapults and Greek fire, fire-throwers. From the late Middle Ages onwards, warships began to carry cannon, cannons of various calibres. The Mongol invasion of Java introduced cannons to be used in naval warfare (e.g. Cetbang by the Majapahit). The Battle of Arnemuiden, fought between England and France in 1338 at the start of the Hundred Y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
178 Mm Artillery
Year 178 ( CLXXVIII) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Scipio and Rufus (or, less frequently, year 931 ''Ab urbe condita''). The denomination 178 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Naval Guns Of The Netherlands
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, 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 broa ...

Pontianak-class Gunvessel
The ''Pontianak'' class was a class of steam screw gunvessels of the Royal Netherlands Navy. The Dutch colonial navy in the 1870s In the 1870s the navy in the Dutch East Indies consisted of an auxiliary squadron of four ships from the Netherlands, and the colonial navy of 22 ships. The auxiliary squadron was primarily responsible for external defense. The ships of the colonial navy (''Indische Militaire Marine'') were meant for transport and flotilla services. In the early 1870s the demands that a war against Aceh would place upon the colonial navy were severely underestimated. When the Aceh War The Aceh War ( id, Perang Aceh), also known as the Dutch War or the Infidel War (1873–1913), was an armed military conflict between the Sultanate of Aceh and the Kingdom of the Netherlands which was triggered by discussions between represe ... actually erupted in 1873, its ships proved to be too defective and too few in number.

RML 9-inch 12-ton Gun
The RML 9-inch guns Mark I – Mark VIMark I – Mark VI = Mark 1 through to Mark 6. Britain used Roman numerals to denote Marks (models) of ordnance until after World War II. Hence this article describes the six models of RML 9-inch guns. were large rifled muzzle-loading guns of the 1860s used as primary armament on smaller British ironclad battleships and secondary armament on larger battleships, and also ashore for coast defence. It should not be confused with the RML 9-inch Armstrong Gun, used by the Dutch navy, the Spanish Navy, and other navies. Design The rifling was the Woolwich pattern of a relatively small number of broad, rounded shallow grooves : there were 6 grooves, increasing from 0 to 1 turn in 45 calibres (i.e. 405 inches). Mark I, introduced in 1865, incorporated the strong but expensive Armstrong method of a steel A tube surrounded by multiple thin wrought-iron coils which maintained the central A tube under compression, and a forged steel breech-piece. 190 ...

RML 9-inch Armstrong Gun
The RML 9-inch Armstrong Gun was a rifled muzzle loading gun, used in substantial numbers by the Dutch navy, the Spanish Navy, and other navies. It should not be confused with the RML 9-inch 12-ton gun, used in the British Royal Navy. Context The rifled breechloader The United Kingdom would adhere to smooth bore guns for a rather long time. In 1850 it held trials with existing foreign rifled breechloading guns designed by Wahrendorff and Cavelli. The outcome was that the government thought that the practical advantage of using these on board ships was limited. Therefore, the United Kingdom primarily adhered to grenade guns and 68 and 32-pounder smooth bore guns. When France started to rifle and reinforce her old cannon, Britain ordered a similar conversion of 300 of its old cannon. This conversion totally failed during the first trials. The Armstrong gun Meanwhile William Armstrong, 1st Baron Armstrong, inventor and owner of a large machine factory, had developed another ...

Chilean Corvette Magallanes (1873)
The corvette ''Magallanes'' was ordered by the Chilean government after the disastrous consequences of the War against Spain in 1864-1866 and the rising border conflict with the neighboring countries at the end of the 1870s. In the extreme southern region of Chile In 1874 she was ordered to travel to the Strait of Magellan to produce charts of the ''Angostura Inglesa'' in the Messier Channel, and of the Bahia Possession in the strait. In January 1876, during patrols off the extreme southern region of Chile and under the command of Juan José Latorre, the French ship ''Jeanne Amelie'' was seized off the coast of Rio Negro as they loaded guano without a Chilean license. By the attempt to bring the ship to Punta Arenas, the ''Jeanne Amelie'' sank on 27 April 1876 at the eastern entrance of the Strait of Magellan. Later the American ship ''Devonshire'' was also seized. In 1877, also under the command of Juan José Latorre, the crew of the corvette put down "''El motín de los ar ...

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 inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to 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 mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Netherlands Navy
The Royal Netherlands Navy ( nl, Koninklijke Marine, links=no) is the naval force of the Kingdom of the Netherlands. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers. The Batavian Navy of the later Batavian Republic (1795–1806) and Kingdom of Holland (1806–1810) played an active role in the Napoleonic Wars, though mostly dominated by French interests. After the establishment of the modern Kingdom of the Netherlands, it served an important role in protecting Dutch Empire, Dutch colonial rule, especially in Southeast Asia, and would play a minor role in World War II, especially against the Imperial Japanese Navy. Since World War II, the Royal Netherlands Navy has taken part in expeditionary peacekeeping operations. Bases The main naval base is in Den Helder, North Holland. ...
