30mm round from a General Electric GAU-8/A Avenger, which is a hydraulically driven seven-barrel Gatling-type auto cannon that arms an A-10 Warthog. The Avenger fires these anti-tank rounds at a rate of 3,600 rounds per minute
The GAU-8 Avenger fires up to sixty one-pound bullets a second. It produces almost five tons of recoil force, which is crazy considering that it’s mounted in a type of plane (the A-10 “Warthog”) whose two engines produce only four tons of thrust each. If you put two of them in one aircraft, and fired both guns forward while opening up the throttle, the guns would win and you’d accelerate backward. To put it another way: If I mounted a GAU-8 on my car, put the car in neutral, and started firing backward from a standstill, I would be breaking the interstate speed limit in less than three seconds.
