Submarine questions
When a submarine is running on the surface with both diesels on propulsion, does this mean he batteries are powering everything on board? Is there no other generator for lighting etc? How long would it take to charge up air and batteries at the same time? Would it be only one of the diesels connected to the dynamo or could both charge at the expense of propelling the vessel?
Also, if ballast is blown at a great depth would water need to be taken on on the way up to compensate for air in the ballast tanks expanding as the water pressure drops?

What type of submarine are you inquiring about?

With regards to the diesels then Uboats. But any submarine with regards the ballast question.

Fleet boats had a smaller engine/generator that could be used to power some of the support systems while on the surface.
BTW, you have a lot of nerve asking a legitimate submarine question here in GT. Don't you know that GT is for whining and illogical emotional comments only?

If you're talking about modern diesel submarines, I'm pretty sure they are all improved versions of the diesel-electric drives developed by the Americans prior to WW2. The diesel engines do nothing but drive the generators. The generators 1) Drive the motors which propel the sub, 2) power the boat's systems, and 3) recharge the batteries. Of course while submerged the batteries drive the motors and power the systems. There is also at least one small axhiliary diesel engine which drives its own generator to help supply power and ease the load of the main generators.

With regards to the boats in SH3, Where you have a choice of having a diesel drive the generator or propell the boat with the other one, would having both propell the boat allow the battaries to slowly drain on the surface due to powering lights etc while both diesels are driving the screws? I know the game is a simplification of reality but just wondered. Would a uboat have had a mini generator for when both diesels are propelling the boat? As there would still be electrical needs of course.
