Thanks, I know that.
My problem, that I obviously didn't clearly express, is that I have a drone/missile with a range of over 4 billion klicks. Designing a missile fire control that goes over 4 billion klicks is pretty expensive, RP-wise, and it will be expensive to build.
Now, I seem to remember that there is a way to fire missiles from a PDC without fire controls, as long as the target is a planet or a jump point. I am asking how that is done - through which window, with what button.
Or alternatively, that I remember wrong and that MFC is always required.
