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.
Later editions of Jane's Infantry Weapons claimed a theoretical cyclic rate of up to 6,000 rpm. George Chinn, author of The Machine Gun Volume V, contended that the XM214 prototype had a rate of fire of up to 10,000 rpm, but the man-portable Six-Pak was limited to 4,000 rpm. General Electric tested it successfully at 12,000 rpm. [3]
In April 2017, Raytheon tested a new electric gun for the Phalanx allowing the system to fire at varying rates to conserve ammunition. The new design replaces the pneumatic motor, compressor, and storage tanks, reducing system weight by 180 lb (82 kg) while increasing reliability and reducing operating costs.
It is also the basis of the GPU-2/A gun pod, which incorporates the cannon, a battery and electric drive motor, and 300 rounds of linkless ammunition. In the Cobra, the weapon is supplied with a magazine of 700 linked rounds, with a total capacity including feeder system of 750 rounds. It has a cyclic rate of fire of 730+-50 rounds per minute.
The Avenger's rate of fire was originally selectable, 2,100 rounds per minute (rpm) in the low setting, or 4,200 rpm in the high setting. [2] This rate was later changed to a fixed rate of 3,900 rpm. [3] At this speed it would take 18 seconds of sustained fire to empty the magazine.
The round is fired by an electric priming system where an electric current from a firing lead passes through the firing pin to the primer as each round is rotated into the firing position. [ 11 ] The self-powered version, the GAU-4 (called M130 in Army service), is gas-operated , tapping gun gas from three of the six barrels to operate the gun ...
Gun regulation has been one of the main topics in the recent months due to a series of unfortunate events that forced the nation to reconsider the current policies.
The Profense PF 50 is a 12.7 mm electrically driven (non gas-operated) chain gun produced by Profense LLC, with a maximum rate of fire of 650 rpm. This weapon is very similar to the M2HB machine gun, however it differs in operation system. It works with an electric motor as on the Bushmaster gun produced by ATK. [1]
