I get Steve's position about not allowing any special components usable by every ship but I kind of think that this is one that perhaps he should reconsider. Even here in the 21st Century, regular fighters and bombers are routinely mid-aired refueled and from a purely technological viewpoint, this is a scalable technology which could be expected to be used in future craft. 'Fighter Pods' are already a niche system and small versions of certain systems, not sure why the line should necessarily be drawn on the refueling side. I also look at it from the gameplay perspective - would it add 'fun' gameplay options? Absolutely. I would clearly design FAC sized tankers and base them on a carrier to extend the range of my fighters and bombers. It would add some interesting tactical options and strategies. I think this addition should be considered.
