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.
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 ...
However, due to the weight of the ammunition, sustained fire is constrained by ammunition payload, as many aircraft cannons only carry enough ammunition for a few seconds' worth of firing; for example, the F-16 Falcon and its variants carry 511 rounds of 20mm ammunition, and the F-22 Raptor carries a similar amount at 480 rounds, which equates ...
It has a rate of fire from 2,000 to 6,000 rounds per minute [6] from a 4,000-round linked belt. As the GAU-2B/A, the Minigun was also used on the U.S. Air Force AC-47, AC-119 and Lockheed AC-130 gunships. The AC-47 was known during the Vietnam War as "Puff the Magic Dragon" and was said to be "the only thing that scared the VC". This weapon was ...
The GAU-22/A's major difference is the use of four barrels, rather than the GAU-12/U's five barrels. The GAU-22/A is lighter and has a reduced rate of fire of 3,300 rounds per minute, but maintains the same, high accuracy of 5 milliradians, 80% circle [2] of the GAU-12 [3] and A-10's GAU-8. [4]
The GAU-13/A is a four-barreled rotary cannon based on the mechanism of the larger GAU-8, sharing the same massive 30 mm ammunition. Like the Avenger, it has a double-ended feed system with reverse clearing to remove unfired rounds. Unlike the GAU-8, however, it is pneumatically driven, giving it a rate of fire of 2,400 rounds per minute.
The first AC-130A Gunship IIs did away with the MXU-470/A mounts and instead used GAU-2/As, and not only had four 7.62mm GAU-2/A minigun mounts, but added four 20mm M61 Vulcan 6-barrel rotary cannons; this configuration was upgraded two years later in 1969 by removing two each of the GAU-2/As and M61s and adding two 40mm (1.58 in) L/60 Bofors ...
Most military use of depleted uranium has been as 30 mm ordnance, primarily the 30 mm PGU-14/B armor-piercing incendiary round from the GAU-8 Avenger cannon of the A-10 Thunderbolt II used by the United States Air Force. 25 mm DU rounds have been used in the M242 gun mounted on the U.S. Army's Bradley Fighting Vehicle and the Marine Corps's LAV-25.
