Since I'm the only one who is on the Surface Warfare Mod team, who, as far as I know, has a copy, I will make an unofficial statement as the second-in-command.
We have stated before that we want to build playable surface ships for SHV. once we get a couple more members on the bandwagon and figure out how to build playable ships, you should see some start popping up. I like the idea of a playable surface ship in campaign mode, with the truly dynamic campaign that is provided, one battleship can change the war faster than one U-boat. I have hopes we will get to talking about this on our private forums soon. I'll see if I can keep everyone updated.
