every submariner will say that, but they don't know
we need a real war to really answer that question
in my mind, the germans have the best submarine but it can stay underwater for only a week or two

These boats use fuel cells to make electricity for the propulsion system. Fuel cells don't have any moving parts.
All of our boats are nuclear and with nukes you need to have a coolant pump to keep the reactor running. Coolant pumps make noise. Steam runs the propulsion turbines that turn the shaft thru a set of reduction gears. Steam also is needed to run the electric generators so you have electricity to run all the other equipment on the boat.
Nuclear boats have speed and they can stay at that speed indefinitally. The german boats in their elelement (the Baltic ocean) will rule supreme.
