As in most submarines the supply of current for driving the electric engines is derived from storage batteries charged by dynamos driven from the petrol engines while the vessels are running on the surface.

The twin screws of the "B's" are placed below the centre line of the vessel and consequently operate in deeper water when the vessels are cruising on the surface. This gives them better surface cruising qualities, as in a sea-way the propellers

Their cruising range on the surface is 4,000 miles, and when submerged 120 knots at 7 knots an hour.
