A-10 Thunderbolt

The A-10 is literally built around its 30-mm GE GAU-8 Avenger seven barrel cannon, the most powerful gun ever fitted to an aircraft of this class. It was designed for high-survivability with a titanium cover surrounding both the cockpit, ammunition and fuel tank. Placement of the engines decreases the infrared signature lowering it's vulnerablity to heatseeking missiles and ground fire.
