The innovative features of the Gatling gun were its independent firing mechanism for each barrel and the simultaneous action of the locks, barrels, carrier, and breech. The ammunition that Gatling eventually implemented was a paper cartridge charged with black powder and primed with a percussion cap because self-contained brass cartridges were ...
The M134 Minigun is an American 7.62×51mm NATO six-barrel rotary machine gun with a high rate of fire (2,000 to 6,000 rounds per minute). [2] It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor.
The Bangerter machine gun uses a blow-forward operation and is the most complex example. The Slostin machine gun uses a similar operation but with gas pistons on each barrels. The GShG-7.62 machine gun and GSh-6-23, both use a more effective, simpler gas piston drive in the center of the barrel cluster.
Rotary-barrel firearms (or rotary guns for short) uses multiple paraxial barrels in a rotating assembly, with each barrel firing automatically when rotated to a designated position, to achieve a rate of fire proportional to the speed of the barrel rotation. Rotary guns are typically belt-fed, though the earlier versions used top-mounted box ...
When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or "rotary cannon", or if it uses a single with a rotating cylinder with multiple chambers, it is known as a "revolver autocannon" or "revolver cannon"; both of these systems are commonly used as aircraft guns and anti-aircraft guns.
This proven system was combined with a purpose-made mounting, capable of fast elevation and traverse speeds, to track incoming targets. An entirely self-contained unit, the mounting houses the gun, an automated fire-control system and all other major components, enabling it to automatically search for, detect, track, engage, and confirm kills ...
The M240 machine gun, officially the Machine Gun, 7.62 mm, M240, is the U.S. military designation for the FN MAG, [6] a family of belt-fed, gas-operated medium machine guns that chamber the 7.62×51mm NATO cartridge. [1] The M240 has been used by the United States Armed Forces since the late 1970s.
Early prototypes had six barrels, but a three-barreled configuration is now standard. The GAU-19/A was originally designed as a larger, more potent version of the M134 Minigun . Due to the loss of nine helicopters in Grenada , GE started building prototypes of the weapon in both a three-barreled and a six-barreled configuration.
