Ok. I have balance for the bombers, gunships and strike craft.
All have unique performance and behaviors.
Strike craft are similar to dive bombers (continuing my WWII analogy). They come in very fast and pack a wallop of damage--enough to usually take out a single scout out in two passes--which they can just do in the time it takes a scout to cross the grav well. They only have 15 hull, a weapon cool-down of 7.5 seconds and a rebuild time of two minutes. This keeps them from being used as throw away uberbombers. They also are much weaker versus heavier armored ships--showing a significant decrease in effectiveness even against light frigates. Enemy fighters make toast of them once they catch them. Interceptors are primarily designed to stop scout reconnaissance and non-antistrike defended small forces behind lines.
I swapped tactics and made the strikecraft more maneuverable so gunships make huge truns and roar in at high speed, heavy bombers make large slow turns and crawl right on top of targets and interceptors shoot in and do hi speed maneuvers "in the thick of it".
Once again, I seem to have mixed some files from a corrupted mod so I am backtracking and cleaning up right now.
