Considering that Fleet Carriers are meant for Squadrons in the currently planned implementation it's certainly more like an aircraft carrier than your personal car trailer.
In case you missed it, just a short recap of the discussion:
A: 'Fleet Carriers should be balanced around Solo players because they have fleets as well.'
B: 'They are more like car collections than fleets.'
A: 'But the term fleet is used for car collections as well.'
B: 'But that's probably not what Frontier meant when they called them Fleet Carriers.'
I went back and read the discussion, but thanks very much for the recap.
I agree that they're more like aircraft carriers than say a mobile garage, but I don't think they will be as combat-oriented as an aircraft carrier is. I see these things more like a C-130 or a bulk carrier.
