German losses, on the other hand, were very high as well. Roughly 12,000 German day fighter pilots were killed or are still missing in action, with a further 6,000 being wounded. The "Zerstörer" (destroyer) pilots suffered about 2,800 casualties, either killed or missing in action, plus another 900 wounded in action. German night fighter losses were also high, in the magnitude of 3,800 pilots or crew members killed or missing and 1,400 wounded. Hans-Ulrich Rudel was the most decorated flying ace in the Luftwaffe, primarily as a ground-attack bomber pilot with over 800 vehicles destroyed in addition to his victories over opposing aircraft.
