Well, now, that's a different issue: there's no reason why fighters in WC couldn't take off any way they like. Mind you, a couple of WC sources - I think the WC4 novel was the main culprit - did add the preposterous notion that ships did need catapults or at least take-off assistance rockets, and that launching without them could be deadly, but we can dismiss that as the writer just being really silly. That said, catapult launches are obviously preferable, because it means the launching fighter doesn't need to worry about being picked off by enemy ships before picking up speed.@Quarto actually, because it's space, there's no reason other than safety one supposes, that they couldn't all launch at once. Cinematic reasons probably trump that anyway.
