Hans Ulrich Rudel destroyed 519 Soviet tanks mostly on his Stuka...He was so successful that I think he was consulted by the Americans when they designed the famous A10 Thunderbolt the worthy successor of the JU87 Stuka and Henschel H129s.

Rudel flew 2,530 combat missions claiming a total of 2,000 targets destroyed; including 800 vehicles, 519 tanks, 150 artillery pieces, 70 landing craft, nine aircraft, four armored trains, several bridges, a destroyer, two cruisers, and the Soviet battleship Marat.[1]
