GAU-8 mounted in A-10. 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 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 USAF equips its HH-60/MH-60 Pave Hawk with one or two GAU-15/A, GAU-16/A, or GAU-18/A.50 caliber machine guns, and or GAU-2 series 7.62mm NATO Miniguns. Example; One .50 caliber MG in the floor, firing out of an open door and two 7.62mm NATO miniguns mounted in the door gunner positions.
The Minigun is a type of rotary machine gun. During the Vietnam War, the 7.62 mm caliber M134 Minigun was originally created to arm rotary-wing aircraft, and could be fitted to various helicopters as either a crew-served or a remotely operated weapon. It has a rate of fire from 2,000 to 6,000 rounds per minute [6] from a 4,000-round linked belt.
The resulting weapon used a smaller version of the GAU-8/A, designated the GAU-13/A, with only four barrels. Podded, the system weights 1,900 lb (860 kg) loaded with 353 rounds of 30 mm ammunition in two helical layers surrounding the gun (for reduction of overall size). The pod is completely self-contained with a rate of fire of 3,000 rpm. [19]
At 50 rps (3,000 rpm), a five-second burst from an M134 Minigun would use approximately 6.3 kilograms (14 lb) of 7.62 mm ammunition; this alone would make it an impractical weapon for infantry who have to carry a reasonable supply of ammunition with them. For this and other reasons, weapons with such high rates of fire are typically only found ...
30 mm (1.2 in) 7-barrel GAU-8 rotary cannon 40 mm (1.6 in) 2-barrel Bofors 40 mm: Rate of Fire 5,000 rounds per minute 10,000 rounds per minute 4,500 rounds per minute 4,200 rounds per minute 600/900 rounds per minute (optionally: proximity-fuse rounds) (effective/ flat-trajectory) Range 4,000 m (13,000 ft) 4,000 m (13,000 ft)
This target was hit six times in a one-second burst of 70 rounds. The GAU-8/A Avenger 30 mm , also used by the A-10 Thunderbolt II aircraft, was selected for the system. The 30x173mm cartridge has a greater projectile mass than the 20x102mm cartridge fired by the Phalanx CIWS M61 Vulcan , so it provides much greater destructive power and ...
