raiders are easy if their ships are becoming to difficult to deal with go after the hq and that will stop anymore ship from coming. mission 5 should be only one their become a problem in as 6 you have so much science you can easy over whelm any raiders that drop by
well i find a easy way to deal with the mission 5 raiders ships destroy their HQ at the start and you don't have to worry bout their ships anymore. 1Y 5M not a single raider ship has showed up
