I’m not sure either. It’s only my opinion, but my reasoning is simple.
Main German bombers, He 111H, Do 217, Ju 87 and Ju 88, roughly 25.000 built.
Main German transport (Ju 52) roughly 5.000 built.
Main German fighters (Bf 109 e 110, Me 410, Fw 190) more than 60.000.
Total of these types built: 90.000.
Almost all of them were lost by war’s end, when Eastern Front reached Berlin, and Russians seized what remained of Luftwaffe.
I consider as combat-related losses aircraft destroyed or damaged beyond repair in air combat, by A.A. fire, or on the ground by strafing and bombing. I consider as combat-related losses also aircrafts captured by advancing ground forces.
This leaves out only aircraft lost in non-combat related accidents, or that reached end of service life. I guessed this number at 20% of total aircraft losses (18.000). This number seems reasonable to me, but obviously I can be wrong.
I guessed also that Luftwaffe suffered “more than half” of its losses on Eastern Front. I’ve read that the actual ratio was 1.7 times of Western Front losses, but even considering a lower percentage, say 60%, the end number is near 43.200.
And that’s it.
