Cloaking technology
Look at wing commander. Cloaking tech was available I think to the Kilrathi in episode 2. Do we ever get it as a standard thing? Nope. Same for Starlancer. We get it as soon as you either get good enough to fly a shroud or you reach the mission where you fly the shroud or the enemy torp bomber. So if we are descendents from the people who fled earth and WHO had cloaking tech...and we have it in NPC ships (but we had to reinvent it using alien tech). Why?
