Pivot Mount
A pivot gun was a type of cannon mounted on a fixed central emplacement which permitted it to be moved through a wide horizontal arc. They were a common weapon aboard ships and in land fortifications for several centuries but became obsolete after the invention of gun turrets. History By mounting a cannon on a pivot, a much wider arc of fire could be obtained than was possible with conventional carriage-mounted cannons. Unlike the latter, however, pivot guns were fixed in one place and could not easily be moved outside of their horizontal arc; they could thus only really be used in fixed positions such as in a fort or on a battleship. There was no standard size of pivot gun, though they tended to be fairly substantial weapons. Like other cannons, they were usually muzzleloaders and could fire either shells or grapeshot (or other types of shot). Their calibers ranged from a few inches to the giant 11-inch Dahlgren guns used by the United States Navy in the mid-19th century. ...

68-pounder Gun
The 68-pounder cannon was an artillery piece designed and used by the British Armed Forces in the mid-19th century. The cannon was a smoothbore muzzle-loading gun manufactured in several weights, the most common being , and fired projectiles of . Colonel William Dundas designed the 112 cwt version in 1841 and it was cast the following year. The most common variant, weighing 95 cwt, dates from 1846. It entered service with the Royal Artillery and the Royal Navy and saw active service with both arms during the Crimean War. Over 2,000 were made and it gained a reputation as the finest smoothbore cannon ever made. The gun was produced at a time when new rifled and breech loading guns were beginning to make their mark on artillery. At first the 68-pounder's reliability and power meant that it was retained even on new warships such as HMS ''Warrior'', but eventually new rifled muzzle loaders made all smoothbore muzzle-loading guns obsolete. However, the large surplus stocks of 68- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Gunpowder
Gunpowder is the first explosive to have been developed. Popularly listed as one of the "Four Great Inventions" of China, it was invented during the late Tang dynasty (9th century) while the Wujing Zongyao, earliest recorded chemical formula for gunpowder dates to the Song dynasty (11th century). Knowledge of gunpowder spread rapidly throughout Asia and Europe, possibly as a result of the Mongol conquests during the 13th century, with written formulas for it appearing in the Middle East between 1240 and 1280 in a treatise by Hasan al-Rammah, and in Europe by 1267 in the ''Opus Majus'' by Roger Bacon. It was employed in warfare to some effect from at least the 10th century in weapons such as fire arrows, bombs, and the fire lance before the appearance of the gun in the 13th century. While the fire lance was eventually supplanted by the gun, other gunpowder weapons such as rockets and fire arrows continued to see use in China, Korea, India, and eventually Europe. Bombs too never c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chase Gun
A chase gun (or chaser), usually distinguished as bow chaser and stern chaser, was a cannon mounted in the bow (aiming forward) or stern (aiming backward) of a sailing ship. They were used to attempt to slow down an enemy ship either chasing (pursuing) or being chased, when the ship's broadside could not be brought to bear. Typically, the chasers were used to attempt to damage the rigging and thereby cause the target to lose performance. Bow chasers could be regular guns brought up from the gundeck and aimed through specially cut-out ports on either side of the bowsprit, or dedicated weapons made with an unusually long bore and a relatively light ball, and mounted in the bow. Stern chasers could also be improvised, or left permanently in the cabins at the stern, covered up and used as part of the furniture. Development In the Age of Sail, shiphandling had been brought to a high art, and chases frequently lasted for hours or sometimes days, as each crew fine-tuned their sails to ...

Apilan And Kota Mara
Apilan and kota mara are two Malay nautical terms which refers to the structure on a vessel where the cannon is installed. This term is used especially on Malay ships and boats. Apilan Apilan (or ampilan) is the wooden gunshield found in Malay prahus where cannons are placed. It has a hole to place long gun, and sometimes swivel gun can be placed over the top of the apilan. Apilan is not permanent, it can be assembled, disassembled, and moved. The crew of Malay prahu operated the long gun behind an apilan. The apilan usually situated at the bow of a prahu. This gun-shield was only put on when the ship went into action. Sunting apilan is the name given to two lelas or light guns standing on the gun-shield of a heavy gun. Etymology Apilan is a true Malay word, it was not descended from any word. It is also a standalone word, due to the fact that the syllable is api-lan instead of apil-an. Kota mara Kota mara is the breastwork or casement of Malay prahus. The functio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Artillery
Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for 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 fire-throwers. From the late Middle Ages onwards, warships began to carry 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 Years' War, was the first recorded Europ ...

USS Kearsarge (1861)
USS ''Kearsarge'', a ''Mohican''-class sloop-of-war, is best known for her defeat of the Confederate commerce raider off Cherbourg, France during the American Civil War. ''Kearsarge'' was the only ship of the United States Navy named for Mount Kearsarge in New Hampshire. Subsequent ships were later named ''Kearsarge'' in honor of the ship. Hunting Confederate raiders ''Kearsarge'' was built at Portsmouth Navy Yard in Kittery, Maine, under the 1861 American Civil War emergency shipbuilding program. The new steam sloop-of-war was launched on 11 September 1861; she was sponsored by Mrs. McFarland, the wife of the editor of the ''Concord Statement'', and was commissioned on 24 January 1862, with Captain Charles W. Pickering in command. Soon after, she was hunting for Confederate raiders in European waters. ''Kearsarge'' departed Portsmouth, New Hampshire on 5 February 1862 for the coast of Spain. She then sailed to Gibraltar to join the blockade of Confederate raider , f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Wabash (1855)
USS ''Wabash'' was a steam screw frigate of the United States Navy that served during the American Civil War. She was based on the same plans as . Post-war she continued to serve her country in European operations and eventually served as a barracks ship in Boston, Massachusetts, and was sold in 1912. Pre-Civil War service ''Wabash''—the first U.S. Navy ship to bear that name—was laid down on May 16, 1854 by the Philadelphia Navy Yard; launched on October 24, 1855, sponsored by Miss Pennsylvania Grice; and commissioned there on August 18, 1856, Captain Frederick K. Engle in command. ''Wabash'' departed Philadelphia, Pennsylvania on September 7, 1856, stopping at Portsmouth, New Hampshire, to embark President Franklin Pierce for passage to Annapolis, Maryland. She arrived at New York on October 23, 1856, sailing on November 28, 1856 to become flagship of Commodore Hiram Paulding's Home Squadron. The squadron was instrumental in foiling the expedition against Nicaragu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RBL 7-inch Armstrong Gun
The Armstrong RBL 7-inch gun, also known as the 110-pounder, was an early attempt to use William Armstrong's new and innovative rifled breechloading mechanism for heavy rifled guns. Description The Armstrong "screw" breech mechanism used a heavy block inserted in a vertical slot in the barrel behind the chamber, with a large hollow screw behind it which was manually screwed tight against the block after loading. A metal cup on the front of the block, together with the pressure of the screw behind it, provided "obturation" and sealed the breech to prevent escape of gasses rearward on firing. The sliding-block was known as the "vent-piece", as the vent tube was inserted through it to fire the gun. In modern terms it was a vertical sliding-block. To load the gun, the vent-piece was raised, the shell was inserted through the hollow screw and rammed home into the bore, and the powder cartridge was likewise inserted through the screw into the chamber. The vent-piece was lowered, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Sidon (1846)
HMS ''Sidon'' was a first-class paddle frigate designed by Sir Charles Napier. Her name commemorated his attack on the port of Sidon in 1840 in the Syrian War. Her keel was laid down on 26 May 1845 at Deptford Dockyard, and she was launched on 26 May 1846. She had a fairly short career for a warship, but it included the rescue of the crew of the sinking P&O ship ''Ariel'' on 28 May 1848, and a trip up the Nile that same year, when her passengers included the explorer and botanist Joseph Dalton Hooker. ''Sidon'' served in the Black Sea in the Crimean War, 1854–55 under the command of Captain George Goldsmith. In April 1854, in company with HMS ''Firebrand'' (Captain William Houston Stewart), she blockaded the coast from Kavarna to the mouths of the River Danube. In September, in the Allied invasion of the Crimea, she was assigned to escorting the French troop transports, and assisted the French line-of-battleship ''Algiers'', which had gone aground in Eupatoria Bay. ...

Cannon
A cannon is a large- caliber gun classified as a type of artillery, which usually launches a projectile using explosive chemical propellant. Gunpowder ("black powder") was the primary propellant before the invention of smokeless powder during the late 19th century. Cannons vary in gauge, effective range, mobility, rate of fire, angle of fire and firepower; different forms of cannon combine and balance these attributes in varying degrees, depending on their intended use on the battlefield. A cannon is a type of heavy artillery weapon. The word ''cannon'' is derived from several languages, in which the original definition can usually be translated as ''tube'', ''cane'', or ''reed''. In the modern era, the term ''cannon'' has fallen into decline, replaced by ''guns'' or ''artillery'', if not a more specific term such as howitzer or mortar, except for high-caliber automatic weapons firing bigger rounds than machine guns, called autocannons. The earliest known depict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swivel Gun
The term swivel gun (or simply swivel) usually refers to a small cannon, mounted on a swiveling stand or fork which allows a very wide arc of movement. Another type of firearm referred to as a swivel gun was an early flintlock combination gun with two barrels that rotated along their axes to allow the shooter to switch between rifled and smoothbore barrels. Swivel guns should not be confused with pivot guns, which were far larger weapons mounted on a horizontal pivot, or screw guns, which are a mountain gun with a segmented barrel. An older term for the type is peterero (alternative spellings include "paterero" and "pederero"). The name was taken from the Spanish name for the gun, pedrero, a combination of the word piedra (stone) and the suffix -ero (-er), because stone was the first type of ammunition fired. Configuration Swivel guns are among the smallest types of cannon, typically measuring less than in length and with a bore diameter of up to . They can fire a variety ...
