All submarines have at least 2 methods of propulsion; with nuclear power, steam generated moves the turbines/main engines, and also makes electricity for battery storage in case of main propulsion failure (electric motor propulsion). A backup Diesel-Generator is also aboard for making electricity if the reactor is down.

Diesel-Electric boats run on electric motors (battery powered) submerged, and on their diesel engines while surfaced.
