I'm trying to figure out all the holes that a submarine has that have to penetrate the pressure hull. Don't ask me why, I just have to know because I'm an obessive-compulsive type ok? I just need to know!
So far I've got (staring from front to back)
1. Torpedo tubes
2. Cable relay from the bow sonar array
3. Forward weapons loading hatch
4. Forward escape hatch
5. Sail access hatch
6. Trim tanks/ballast tank ports
7. XBT launcher
8. Seawater coolant flow hatch? in a SSN that is.
9. Inlet for the seawater to freshwater conversion tanks
10. Aft escape hatch
11. Countermeasure launcher
12 Main drive shaft
13. Maybe a waste disposal hatch? To dump sewage?
Anything I'm missing?
EDIT: Stuff I forgot.
14. Sail penetrating mast like the scope, exhaust, snorkle, hole, etc.
15. Auxillary seawater intake
16. Hydraulics for control surfacts (I didn't realize these were originating inside the pressure hull.
17. Other stuff that I don't even know what they do.
