Does anyone have any idea by what significant margin the F-35B will fall short of the performance standard of the F-35A and F-35C?
Biggest short coming of the B vs A & C is internal weapons bay. Much smaller so it can't handle internally many of the weapons the other two can handle. Second is range. Less fuel and more drag. But its much much much better than Harrier or any other STOVL, so things are relative.
