The A-10 attack aircraft, officially the Thunderbolt II but unofficially the Warthog, is the U.S. Air Force's ugliest plane by far but also its toughest. During Desert Storm, which I served on Temporary Duty on the USS McKee ( AS-41 ), the aircraft was first used then and it became the infantryman's favorite aircraft for it can fly low and slow and loiter for a long time and support the foot soldier much better than the supersonic fighters the Air Force really likes which is one reason the Air Force has been trying to kill it for years but the Army and Congress have denied them the opportunity to do so. I remember talking to an Air Force aircraft mechanic and he stated it was the easiest aircraft to work on because it is relatively simple AND it can be jerry rigged unlike the F-16 or F-15's that he worked on. While the other aircraft can only be patched up with the manufacturer's expensive parts for fuselage repairs, he told me the A-10 fuselage could be patched up with .... beer cans. Because they fly low, the aircraft get damage from light firearms like rifles and even handguns but the bullet holes can be patched up by cutting up the beer can, flattening to fit in the area and riveted in place because they don't interfere with the aerodynamics so much because the aircraft isn't so fast. Try that on a F-15.
It's most impressive weapon is it seven barrel, 30 MM Gatling gun which fires depleted uranium shells which penetrate all known tank armor with its massive kinetic force.
