Later in the war, acoustic homing torpedoes were developed, which steer themselves automatically towards the propeller noise generated by the target ship. Spare torpedoes were carried both internally, and externally beneath the outer hull. If the submarine needs to be moved at the surface, seawater is rushed out of these tanks and in place of sea water, compressed air is inserted into the tanks. possibly both.
