Just got a bunch of documents from the USAF Historical Archives.
These figures are for USAAF Day fighters ONLY. They do not include the RAF, RCAF, or any other allied air force. They only include the USAAF fighters engaged in western Europe.
Some telling statistics for 1944:
USAAF Day fighter Losses - 4,897 planes lost in combat
Pilots Lost in combat - 2,801
Aircraft of all types claimed destroyed in Air to Air Combat - 5608
Sorties Flown - 365,284
Escort Sorties - 207,532
Above sortie figures does NOT include 30,706 non-effective sorties that turned back due to weather, technical problems, or other reasons.
Average Number of USAAF fighters vs. Luftwaffe fighters in engagements - 8.6: 1
Total number of sorties flown by the Luftwaffe in all fronts during 1944 - 66,300
Roughly 75 percent of the Luftwaffe day fighters on the Western Front in 1944 were FW-190A's. For the majority of time in 1944, the predominate FW-190 was the FW-190A8.
