The GAU-8 Avenger is not a gun to play with. It’s so massive that the rest of the airplane has to be built around it. The primary function of the weapon is to take out enemy tanks. This is done by its incredibly high firing rate. The GAU-8 Avenger fires a whopping 3,900 rounds per minute. Because of this, the Avenger holds the record for largest gun in a combat jet.
The heavy gun was introduced into combat in 1977 after a lengthy development by GE. 40 years later, the GAU-8 Avenger remains an important piece of military technology and very impressive to see in action. You definitely don’t want to be in a tank if you see one of these flying overhead.
