Hi Hooligan,
>It seems to me the spitfire airframe underwent a lot more development as time passed compared to what happened with the 109.
Actually, the opposite is true. New Spitfire versions were created by mounting a new engine on the original aircframe, with few changes (usually just an increase of the radiator size).
The Me 109 on the other hand was completely re-designed with the Friedrich, with new wings, radically different radiators, and a completely new tail section.
So in 1945, the Me 109 had a much more modern airframe than the Spitfire, yet noone considered the Spitfire outdated (at least, not more than any other propeller fighter).
>This lack of airframe advancement is probably why late model 109s are capable of entering compression at the top end of their level flight speed.
Utter nonsense (or you greatly overstimate the Me 109's level speed :-) The Me 109 could dive to Mach 0.79, about the same as the Fw 190 and the P-51, and considerably better than the P-47 and the P-38.
>To address the original question: Losing wars catastrophically is very bad for k/d ratios. Almost all of the 35,000 109s made were destroyed so their k/d ratio is undoubtably horrible.
According to Edward Sims' "The Fighter Pilots", the Luftwaffe claimed about 70000 victories, for the loss of 8500 pilots KIA, 2700 POW and 9100 wounded in action, for a total of ca. 20000 losses. Not knowing the real numbers, we could speculate there were another 20000 pilots who bailed out OK, that we arrive at a 70000:40000 kill ratio for the Luftwaffe, or 1.75:1. That's not bad at all considering the catastrophic finale.
