Question: Can you confirm if the boats ran on their electrics all the time? It seems I read that the diesels were used just to drive the generators which in turn both charged the batteries and drove the electrics. There was typically no direct drive from the diesels to the screws.
Was curious if you know if this is correct.
THanks Again!!!

Yes, this is true.
This is what the propulsion was basically like:
Here is a good page:

For example:
The Cavalla was equipped with four big diesel engines. The engines were not for direct propulsion but to drive a direct-current generator on the back of the engines. The generator provided electrical current to drive motors that turned the propeller. When the Cavalla was converted to a submarine killer in 1952, one of the diesels was removed to make way for a sonar room.
