Kurt Welter (25 February 1916 – 7 March 1949) was a German Luftwaffe fighter ace and the most successful Jet Expert of World War II. A flying ace or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat. He claimed a total of 63 aerial victories—that is, 63 aerial combat encounters resulting in the destruction of the enemy aircraft—achieved in only 93 combat missions. He recorded 56 victories at night, including 33 Mosquitos, and scored more aerial victories from a jet fighter aircraft than anyone else in World War II and potentially in aviation history.
