Fairchild A-10A Thunderbolt II

Called the Warthog by its pilots and ground crews the A-10 is not the prettiest aircraft ever built, but it is extremely good at its job -- killing tanks. Designed around a massive 30mm rotary cannon capable of firing up to 4,200 rounds per minute and with large amounts of titanium armor around the cockpit and engines the A-10 is almost a flying tank itself. The A-10 proved its capabilities in the 1990-91 Gulf War by destroying several thousand Iraqi tanks, and other vehicles.
