I don't think this is in (I certainly haven't encountered it, but I'm fairly new to the game), but I was wondering how difficult it would be to add the ability to produce ordanance etc in deep space? As in, you have a shipboard module, a cargo hold full of of the necessary minerals, and if you give the order, it starts producing missiles. Right now, you can sort of approximate it by lugging factories around, dumping them on planets and then setting them to work, but it's less than ideal.
Basically, I want to be able tow a big fat ship out into deep space, and have it sit there, being fed minerals from my roving harvester fleets, which it converts into missiles, maintenance supplies, and I suppose fighters.
