F-35 has lots of problems, but it does not cost a billion a piece to build. And I&#x27;m not sure that drones vulnerability to ECM will ever be solved, so quite likely there is always going to be a role for a manned fighter.<p>Whether F-35 should be that fighter is another question, there is a lot of disagreement on that one among people far more qualified than me, so I have no opinion there.
