It will be very hard and expensive to sort out all the problems and getting the F-35 combat ready and combat efficient. It is of course hard for any of us to know exatly what it is capable of but from what is heard the overall performance is so far a disapointment and it is a little worrying that it seems to have problems even on a basic level with aerodynamic and maneuverability. If so it will be almost impossible to fix it without a complete redesign if the plane. Software issues etc can be sorted out along the way but the basic airframe design must work.
