"Mine would have to be the ugly duckling that never got a chance to take on the Germans, but tore through Japanese fighters like crap through a goose and later served in Korea: the F4U Corsair."
Fleet Air Arm Corsairs took part in the raids against the Tirpitz docked in Norway..but encountered no air opposition.
I believe there was one encounter between FAA F-6F Hellcats and a mixed bag of Fw-190s and Me-109s..the Brits shot them all down with no loss..I'll see if I can find the actual reference.

Corsair JT404 of 1841 squadron. Involved in anti-submarine patrol from HMS Formidable enroute to Scapa after Operation Mascot against the German Battleship Tirpitz, in company with Barracuda of Wing Leader Lt Cdr RS Baker-Falkner. Emergency landing in a field at Sorvag, Hameroy, near Bodo, Norway on 18 July 1944. The pilot Lt Mattholie taken POW and the aircraft captured intact with no damage. The german authorities made attempts to get the pilot to explain how to fold the wings so as to transport the aircraft to Narvik. Aircraft was ferried by boat for further investigation. It is not known if the Corsair was taken to Germany. This was probably the first Corsair captured by the Germans. Aircraft is listed at Rechlin for 1944 under repair.
