If it's going to actually be Joint, then it has to be able to land on a cv and an airfield. Hence: don't build the A. (And for air superiority, build more F-22's FFS).
OK. So really only the B is Joint since it is the only one that can land on a CV, an LHA, a long runway, and a very short/no runway. And I totally agree with the F-22 point, but it would seem that ship has sailed and is not turning back. And no F-22s are Joint.
