I have asked this exact question in the forum for Ten for the Chairman. No answer last week, so hopefully CR bites this week.No valuable contribution here- just jumping on the Carrack hype train, CHOO CHOO!
But seriously, this is the sexy beast that got me in to larger ships. So damn cool. And I'm really interested in the snub-fighter; for some theory crafting, what if the parasite ship could fly through small points itself- not go very far mind you, and with the Carrack on the immediate other side, but it would be like a little fishing line cast in to the deep. Map with the Carrack's computers, send the snub through to check, come back and give the all clear to allies in other ships near you!
My point was that the Carrack is a dedicated exploration ship. It doesn't make sense to not be able to send something through small jump points. Hence the snub should definitely have a jump drive.
