First off, I'd like to say the USS Ohio mod is excellent.
Reminds me of the movie Crimson Tide. I've toy'd around with the mod a little bit trying to figure out how to make the top SLBM hatch doors open and close and act as functioning torpedo tubes. I've figured out how to put a tube door on top, but there is no tube chamer as a part of the ship's shell on top, but only in the front. It's to my assumption the tube chambers are necessary so the torpedo won't explode inside your submarine. (Please correct me if I'm wrong. I'm trying to figure it out as I go along) If anyone has ideas or suggestions to this idea, I'd be very interested in them.
