SELECTOR,
So having:
1939: Spitfire Mk Ia (+6lbs boost, saw no combat)
1940:
1941:
1942: Spitfire Mk Vc (+16lbs boost), Spitfire F.Mk IXc (Merlin 61, only 300 built, +15lbs boost), Seafire Mk IIc (+16lbs boost, less than 300 built)
1943:
1944: Spitfire F.Mk XIV (+18lbs boost, fails to match historical climb rates and is highly perked)
1945:
is fine?
Why would you want a Spit VII? It was practically nonexistant.
