The Bf 109 was flown by the three top-scoring fighter aces of World War II: Erich Hartmann, the top scoring fighter pilot of all time claiming 352 victories, Gerhard Barkhorn with 301 victories, and GŸnther Rall claiming 275 victories. All of them flew with Jagdgeschwader 52, a unit which exclusively flew the Bf 109 and was credited with over 10,000 victories, chiefly on the Eastern Front. Hans-Joachim Marseille, the highest scoring German ace in the North African Campaign, also claimed all of his 158 victories flying the Bf 109, against Western Allied pilots.
