I am not very sure if there has been threads on this before but I just thinking about planetary defense. What I am thinking is that maybe there should be ground defense into space, kind of like stawars EAW. I think that the planetary defense should have one defense per planet (Example - Ion cannon for TEC). This will use up tactical slots and you can not have it along with the planetary shield as the shield would just block the shot. The defense will also have a warm up period and the range will not extend as far as the planet space goes, but more around the area of the planet. The warmup period will happen as soon as ships move into the planets space or when they entering the Phaseline.(presuming you have the radar tech)

Does this sound like a good idea?
