Quieter Electric Motors
Lowers Electric motors noise level from 88-95 dB to 82-90 dB (depending on speed setting).
Enemy escorts will now hear you from 750 meters or so at flank speed and within 150 meters at slowest speed.
Allows a bit more maneuverability inside convoys or during escape.
Beware: at higher speeds, propeller cavitation will add to your sub’s noise level if you’re too close to the surface. Stay at 25 meters or below for maximum stealth!
Requires a new save.
