I agree with Howdidudothat and VARoadstter for two reasons.
a) this is the kind of kill relation we have come to expect from sci fi. look at space shooters like freespace or x-wing etc. fighters dont kill big ships. in fact they dont even make a dent (I spent 15 minutes trying to kill a damaged shivan corvette once because I just wanted that kill). bombers do. thats about the only thing they do. they are a tad slower, less agile, but heavier and have the bigger guns. period.

there is an option to keep strikecraft docked. so, this could in effect become a pretty nice strategy. knowing you have several squads of bombers that could shred the enemy fleet apart, but first you need other ships to take down enemy fighters and flaks. maybe keep fighters undocked but close by for defensive action. then, if you manage to knock out enough enemy anti strike craft capacity, you can send them on their nasty mission.
maybe a nerf on another point might be interesting as well. maybe it should take more antimatter to replace strikecraft, so they are still a powerful unit, but not so much of a throwayay unit. currently, you can send them in because they get replaced reasonably fast. if you keep them as powerful as they are, but with a much longer rebuild time, this could make for a very different, and much more exciting balance. and its a very soft change, compared to some voiced who suggested resource cost for strike craft similar to sc carriers.
