F6F's loss ratio was inevitably assisted by the fact that by late 1943 most of the decent Japanese stickmen were dead or (rarely) captured, and the aircraft were obsolete or obsolescent. The few decent aircraft the Japanese were able to field were hamstrung by tactics, inexperience and a lack of Avgas.
Yup, any type would perform well in a turkey shoot.
The same could be said for the F15 kill ratio - have they ever come up against quality opponents backed up by their own AWACS etc?
Strange - no one has mentioned the F3 yet...
