I see the graphic issue immediately. A ww2 sub visually tracked and fired on the target most of the time. Watches were stood on deck, on the surface a fair chucnk of each day. Ships were observed to have been sunk with Mark 1 eyeballs. Small craft were attacked with guns.
A cold war sim puts you underwater. The firing solutions are gathered passively, no eyeballes except looking at a CRT. Surface watches? Putting in to port. Kills? Not observed, the proper data gathered.
Unless you play with all kinds of externals on all the time in a 3d person view the pretty view would be entirely inside the boat.
