I was thinking of the possibility of a group of smugglers/pirates using a (smaller-ish) capital ship as a mobile base of operation.
First, I was thinking of the smallest ship with fighter carrier capacity. Perhaps the Nebulon-B frigate? I am not looking for a firepower base, but merely a ship that can carry, repair and resupply a smuggling/pirate fleet.
Second - and thats the fun part - what would be the consequences of owning that sort of large ship? Are you more likely to be trapped by the Empire? Do you think they could be the target of rival criminal groups that would figure its an easier target to capture compared to Imperial/Alliance similar ships?
How costly is such a ship to operate? How much parts, fuel, crew do you need to keep that thing flying?
