Updates for the Piranah Project 865 midget submarine.
The first model p.865 carries four torpedoe tubes, not two. It also has other sensors such as sonar that are currently not in the game model.
1. Aft (rear) light
2. Rudder
3. Steerable shrouded propeller
4. Hydroplanes
5. Recesses for folding masts
6. Electronic Warfare mast (folding, port side)
7. Snort mast for diesel engine (folding, center)
8. Communication antenna (folding, starboard side)
9. 21” (533mm) torpedo tubes (4 in total)
10. Navigation light (green = starboard, red = port)
11. Main access hatch
12. Fair weather conning tower for surface use
13. Folding watershield
14. Radar antenna
15. Periscope
16. Forward light
17. Torpedo tube doors
18. Sirena-UM 2-man Swimmer Delivery Vehicle (x2 in torpedo tubes)
19. Latouche 400mm active-passive anti-ship torpedo (x2)
20. Bow hydroplanes (fold aft)
21. Diver lock-out chamber with ‘moon pool’ hatch in floor
22. Flooded outer hull
23. Passive sonar array
24. Fiberglass sonar dome
25. Sonar dome for active sonar array
26. Diver access hatch in outer hull
27. Spetsnaz diver
28. APS underwater assault rifle
29. IDA-71 rebreather
30. Command center
31. Habitation space
32. Batteries

Successor designs
Piranha-T - small attack submarine variant with mix of 533mm and 400mm torpedo tubes. Limited diver capability (possibly exit via torpedo tubes).
U-130 - smaller dual-role attack and special forces submarine. Retains diver lock-out chamber with moon pool
Piranha-2 - updated special forces submarine. Extended hull may allow AIP (air-independent propulsion). Appears to sacrifice 533mm torpedo tubes for 400mm which would preclude the Sirena-UME SDV and some DPVs
Piranha-M - very few details.
Added 2 UUV/ROV facilities to model outer torp/UUV tubes.
Will keep digging for more info on sensors and torps.
