I know we have to level the subs just like the air ships, when can we build more of them? how many of us have 2 or more right now? it's been a minute since airships was new =D

I believe you'll need to reach specific sectors to unlock more submarines, similar to airships. I have 2 subs going, but they're on separate FCs.
