List of German World War II night fighter aces: A flying ace or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat.  German day and night fighter pilots claimed roughly 70,000 aerial victories during World War II, 25,000 over British or American and 45,000 over Soviet flown aircraft.  103 German fighter pilots shot down more than 100 enemy aircraft for a total of roughly 15,400 aerial victories.

Another 500 fighter pilots claimed between 20 and 40 victories for a total of 15,000 victories.  According to Obermeier, it is relatively certain, that 2,500 German fighter pilots attained ace status, having achieved at least 5 aerial victories.  453 German day and "Zerstörer" (destroyer) pilots received the Knight's Cross of the Iron Cross.  85 night fighter pilots, including 14 crew members, were awarded the Knight's Cross of the Iron Cross.

Victor Fyodorov: Lieutenant Viktor Georgiyevich Fyodorov (11 November 1885 - 4 March 1922) was a Russian World War I flying ace credited with five aerial victories while flying with the French military air service.  Having left Russia for Belgium in 1908, with a further move to France, Fyodorov was still living in the latter when World War I began.  On 21 August 1914, he volunteered for the French Foreign Legion, and served with them until wounded and invalided from infantry service.  After preliminary duty as a chauffeur, he became a pilot on 27 November 1915.

He claimed a total of 63 aerial victories—that is, 63 aerial combat encounters resulting in the destruction of the enemy aircraft—achieved in 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 possibly in aviation history.  However this score is a matter of controversy; research of Royal Air Force losses suggests Welter overclaimed Mosquito victories considerably.
