The P-47 wing, or What am I looking at?

[JtD]

The Spiteful wasn't just a Spitfire with a laminar flow wing, it was a completely new plane. Maybe they were as similar as the 109E and the 109F. That's not a reference for relative performance, and neither will be Typhoon/Tempest nor P-39/P-63 nor P-40/P-51.

Try looking at size, weight, surface quality and plane particulars instead of the airfoil for the XP-47F.
