The A-10's unofficial nickname is the Warthog.P.S. The official name for the A10 "Warthog" is the "Thunderbolt II."
It was named after the WW2 era P47 Thunderbolt because both of them were most famous as low level attack and tactical ground support aircraft.
And both of them were tough as nails and could get shot up badly and still fly the pilot home safely.
The P-47's unofficial nickname was the Jug. When they were brought over to England, the British thought that was short for Juggernaut (which is the way they would have named things). Actually, the Americans named it that because of was difficult to learn to control; if you weren't careful with the wheel brakes, it would stand on its nose. Looking like a milk jug.
