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''. The earliest known depiction of cannons may have appeared in Song dynasty China as early as the 12th century; however, solid archaeological and documentary evidence of cannons do not appear until the 13th century. In 1288, Yuan dynasty troops are recorded to have used hand cannons in combat, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caliber
In guns, particularly firearms, but not #As a measurement of length, artillery, where a different definition may apply, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms), bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters]ref name=barnes2016-p9> In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a US "45 caliber" firearm has a barrel diameter of roughly 0.45 inches (11.43mm). Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise spe ...

Great Turkish Bombard
The Dardanelles Gun or Great Bronze Gun ( or simply ''Şahi'') is a 15th-century siege cannon, specifically a super-sized bombard, which saw action in the 1807 Dardanelles operation. It was built in 1464 by Ottoman military engineer Munir Ali and modelled after the Basilic, the bombard crafted by Orban that was used for the Ottoman siege of Constantinople in 1453. History The Dardanelles Gun was cast in bronze in 1464 by Munir Ali with a weight of 17 tonnes and a length of , being capable of firing stone balls of up to ). The powder chamber and the barrel are connected by the way of a screw mechanism, allowing easier transport of the unwieldy device. Such super-sized bombards had been employed in Ottoman warfare and in Western European siege warfare since the beginning of the 15th century. According to Gábor Ágoston, the technology could have been introduced from other Islamic countries which had earlier used cannons or from Europe. The Ottoman army successfully ...

Fire-lance
The fire lance () was a gunpowder weapon used by lighting it on fire, and is the ancestor of modern firearms. It first appeared in 10th–12th century China and was used to great effect during the Jin-Song Wars. It began as a small pyrotechnic device attached to a polearm weapon, used to gain a shock advantage at the start of a melee. As gunpowder improved, the explosive discharge was increased, and debris or pellets added, giving it some of the effects of a combination modern flamethrower and shotgun, but with a very short range (about ), and only one shot (although some were designed for two shots). By the late 13th century, fire lance barrels had transitioned to metal material to better withstand the explosive blast, and the lance-point was discarded in favor of relying solely on the gunpowder blast. These became the first hand cannons. Design The first fire lances consisted of a tube, usually bamboo, containing gunpowder and a slow match, strapped to a spear or other po ...

Autocannon
An autocannon, automatic cannon or machine cannon is a automatic firearm, fully automatic gun that is capable of rapid-firing large-caliber ( or more) armour-piercing, explosive or incendiary ammunition, incendiary shell (projectile), shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal ballistics, terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns, or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single gun barrel, barrel.

Automatic Weapon
An automatic firearm or fully automatic firearm (to avoid confusion with semi-automatic firearms) is a self-loading firearm that continuously chambers and fires rounds when the trigger mechanism is actuated. The action of an automatic firearm is capable of harvesting the excess energy released from a previous discharge to feed a new ammunition round into the chamber, and then igniting the propellant and discharging the projectile (either bullet, shot, or slug) by delivering a hammer or striker impact on the primer. If ''both'' the feeding and ignition procedures are automatically cycled, the weapon will be considered "fully automatic" and will fire continuously as long as the trigger is kept depressed and the ammunition feeding (either from a magazine or a belt) remains available. In contrast, a firearm is considered " semi-automatic" if it only automatically cycles to chamber new rounds (i.e. self-loading) but does not automatically fire off the shot unless the user m ...

Mortar (weapon)
A mortar today is usually a simple, lightweight, man-portable, Muzzleloader, muzzle-loaded cannon, consisting of a Smoothbore, smooth-bore (although some models use a Rifling, rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a Sight (device), sight. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. Historically mortars were heavy Siege, siege artillery. Mortars launch explosive shell (projectile), shells (technically called Bomb, bombs) in high arching Projectile motion, ballistic trajectories. History Mortars have been used for hundreds of years.
