The range of the F-35 is too low for the Navy, because it sits in the F-16 concept. But there is no fighter/interceptor split in the AF either, and the range is too low for AF as well.
So now we have the F-47, a very belated ack that the F-35 has short legs. But it also won't fix the problem because it is too focused on the F-22 role, absolute air dominance against e.g. J-20.
No one should call it success. It is what it is.
