The way fighters are now is really screwed up. The offense plus and defense plus of each fighter in the group stacks. Worse one additional multiple is added to every stack. A group of 10 small fighters has 880% defense plus benefit and a 550% offense plus benefit. No wonder nothing can hit a large group of fighters except PD. Even the same size Groups of fighters can't hit each other.
Fighters can be sort of fixed by giving the cockpit the bonus normally applied to the fighter hull. This makes it tough to differentiate between fighter sizes but it beats the alternative, fighters always having a 99% weapons to hit, and eliminates the benefit of large fighter Groups over small fighter Groups in fighter to fighter combat.
Fortunately you can only add one cockpit. If you try to add more you get a warning.
I guess if you were really dedicated you could try to create a small, medium and large cockpit but I don't know if that can be done.
