Yes you're right Kpt Lehmann in stock SH3 you can at least with type IX and type VIIB to maintain depth with very low speeds or at all stop at any depths.
Maybe my first post was specific to type VIIC/41 or I was interrupting a crash dive order.
Yea too bad SH3 doesn't take into account the compressed air used during depth changing. That would be so very cool. Anyone tried to mod this
?
I have another question more like an idea on modding 'rig for silent running' command, a simple one really but I think I prfer to start a whole new thread for it.
