What is in the after torpedo room?

The after torpedo room includes:

1. Four torpedo tubes, which would normally be loaded.
2. Four reload torpedoes.
3. Torpedo loading hatch.
4. Crew’s bunks above the torpedoes.
5. A signal gun to send out flares. After WW2, it could also be used to release decoy devices.
6. There is no lower level in this compartment since the propellor shafts pass through the area below this space outside the pressure hull.
7. This space has the unique head that discharges directly over the side and cannot be used in port or when submerged. It requires an eight-step process to flush since the water level outside the boat is significantly higher than the water and waste in the bowl. If flushed incorrectly, the user gets to clean up the dirty water.
8. After escape trunk.
9. Charging unit for the Mark 18 electric torpedoes.
