As another thought, would the sub have emergency bilge pumps for the removal of flood water? I ask because to rapidly estinguish a fire in the fore torpedo room that I couldn't seal off due to the bulkhead door being destroyed, I locked all adjoining doors, opened the torpedo room vents and flooded the room. This put the fire out fast but i am unsure how to remove the excess water from the boat, which was now sitting on the sea bed at 30M deep.
