Thanks so much for your help and so far the only thing I modded in your XXI is to boost the speed a little to match a nuke sub's speed. Out of curiosity I boosted its speed to 50 knots which makes diving really fast but its almost impossible for the plainsmen to level off in time. (If 50 meters is ordered the sub dives down to 130 before rising back up to 50.) So I made the surfaced speed 33 knots and underwater speed 25 knots maximum.


Maybe I'll be able to mod one of the torpedoes and turn it into a cruise missle and hit RAF targets with it :hmmm: Gotta love games where mods can literally create a whole new world.
