Here is a request from the old Starfire guy. How about a mobile shipyard for building pdc's owp's, and for forward ship repair.
Maybe a smaller shipyard, like the small jump gate builder
One of the things I wanted to get away from in Aurora was Starfire's amazing mobile shipyards. With no supporting population or industry they can somehow build capital ships in the middle of nowhere

However, you can do some things in Aurora that replicate some of the Starfire abilities. For example, although you can't have "mobile shipyards" in the sense they have their own engines, the shipyards are mobile in the sense that you can move them with a tug. If you create a small colony in a forward area to provide the workforce and you have sufficient minerals, you can tow a shipyard to that planet and use it as a forward base. Also, don't forget your ships can self-repair using damage control. If you provide them with enough maintenance supplies, they can repair just about anything except armour. Repairs require double the maint supplies of preventative maintenance so a ship would need supplies equal to 2x its most expensive system in order to be assured of repairing everything.. Ships in a hangar can use the mothership's maintenance supplies so you could create a ship with a huge hangar and loads of maintenance supplies and use it as a repair bay, bringing ships into the bay to let them repair their own systems. That method gets around the problems suffered by ships with limited maintenance capacities. In fact, I should probably allow ships in hangars to use the mothership's damage control rating so you really could build true repair ships.
EDIT: In v4.8, any ship in a hangar will use the Mothership's damage control rating if it is higher than its own. Ships can already use the Mothership's maintenance supplies in v4.77. As well as allowing carriers to repair their fighters/FACs, this allows the creation of dedicated "Repair Ships" with large hangars, high damage control ratings and lots of maintenance supplies.
