I have noticed that during WWII the Germans captured quite a few P-47s, P-51s, Spitfires, and other Allied aircraft. I know that they tested them extensively but wanted to know if they ever used them against Allied aircraft.
Not sure about the Germans, but the Italians used a P-38 (from the site 12 O'Clock High):
The piece about the P-38 captured by the Regia Aeronautica is extremely correct (at last, I was sick of reading accounts or questions mutuated from the complete fantasy of Martin Caidin...! ), except for one detail: the plane shot down on August 11, 1943 by Col. Angelo Tondi with the P-38 wasn't a B-24 but a B-17 instead...
and later on the same post:
This is extracted from the diary of 2nd Lt. James Franklin Boston:
"August 11, 1943-Mission to Terni, Italy 06:00. Carried 6000 lbs. demos. (demolition bombs). Flak moderate. Coming back 60 miles from Italy intercepted by ME-109 and captured P-38 with enemy flier flying it. Nobody fired at first, thinking it friendly. Saw it slip in a formation from behind and shoot down a B-17. Everybody fired at it then including myself but my gun jammed. 20mm shell came by my head while I was looking through astrodome and went into No. 2 engine. P-38 was not shot down."
Yes they did.
Kampfgeschwader 200 flew recon and supply missions in captured bombers.
Here's a good few more captured examples: German Warplanes 1939-1945, Captured Allied Aircraft in Luftwaffe service Among them:
- A Fairey Swordfish was maintained in serviceable condition for around six months, one has to ask why.
- A special squadron, the Zirkus Rosarius, went around training front-line squadrons against them, not sure if you'd regard that as "operational", but it is more than mere test and evaluation.
- Several examples are transports. Given the Kampfgeschwader 200 use of bombers in this role, it might seem unlikely that these others were never used in their intended role.
