I agree run electric on surface ca n be a tactical advantage.

But I do not understand the advante of run one shaft forward and one back on a sub. They have only to shafts because the engine power of one diesel was "low". If it would such a big point they would not change design to one screw in modern subs, isnt?

Call be dumb but compared to the lenght and mass of a sub the two screws are very close together. Will the water flow not create 90% carvitation and only a 10% turning advantage in trade off a big loss of speed?

..even you will outturn mostly all surface threads with only rudder actions...

I mean isnt it better go as far as possible before these cans detonate?

Ok, you can conserve fuel by running only on one screw...in trade of speed.
