Historical Record

Provenance & Service

General Electric's GAU-8/A Avenger is a 30 mm hydraulically-driven Gatling cannon firing 3,900 rounds per minute. The A-10 Warthog was, famously, designed around the gun rather than the other way around. Its depleted-uranium PGU-14/B armour-piercing round made the Avenger the definitive Cold War tank-buster.
