A-10 Thunderbolt aka ‘Warthog’

The A-10 Thunderbolt II, a snub-nosed ground-attack plane nicknamed the “Warthog,” is outfitted with a seven-barrel Gatling gun the size of a Volkswagen Beetle in its nose. The Cold War-era plane has a reputation for tearing apart armored tanks and clearing the way for troops on the ground with its massive 30-millimeter rounds of ammunition.
