why do you want it faster, it was designed for 12kts and to conduct a search for 30 minutes. It was an effective torpedo for a homing torpedo. In real life if you made it faster, and they tried, you would over power the acustic seaker with its own propulsion unit. Remember this thing was a passive homer torpedo, and i think they did a half way decent job of modelling it here.

Is this a modification for the Cold War campaign mod? Some of the other guys have been trying to create or modify existing torpedoes to make more advanced cold war versions.
