30mm GAU Cannon

The GAU-8/A Avenger is an American 30mm Gatling cannon produced by General Electric and is the primary armament of the A-10 Thunderbolt II. Using a combination of armor-piercing incendiary depleted uranium rounds and high-explosive incendiary rounds, the system is designed to defeat heavily armored vehicles.

Similar weapon systems include the Russian Gryazev-Shipunov GSh-6-30.

Battlefield 4
The 30mm GAU Cannon is the sole primary weapon for attack jets in Battlefield 4. It inflicts great damage against ground vehicles, capable of completely destroying one in a single gun run. It is a separate weapon from the 30mm Cannon available for other vehicles.

Unlike other appearances of attack jets in the Battlefield series, the 30mm GAU Cannon in BF4 has slight drop over range due to gravity. It also has slight spread, but does not lose accuracy as the stealth jet cannons do. It has a very high fire rate of 2000 rpm—same as the 20mm Cannon, while inflicting much more damage.
