Hi Hitman,

thanks for the answer. Do you have some information about this:

@h.sie: I found more data about the submerged endurance of the VIIC. In the original 'U-Bootskunde' book for the VIIC from 1940 is a detailed description about the air cleaning mechanism with calculations about when the first oxygen has to be added...
At the end of the section it says:

'Der vorhandene Sauerstoffvorrat in Verbindung mit den Alkalipatronen ermöglicht, bei einer Besatzungsstärke von 37 Mann 72 Stunden ohne Unterbrechung unter Wasser zu bleiben.'

Usually, in SH3 more than 37 men are on board (Max. 51, Min. 32). Using a crew of 42 men, we can estimate a submerged endurance of 63 hours. So, I think we have historical information for the VIIC, IXC, and XXI. What is still missing is data about the type II.

To summarize:

Technical requirements for:
-IIA/D: ? maybe also 72 hours with xx men?
-VIIC: 72 hours with 37 men
-IXC: 72 hours with 44 men
-XXI: 150 hours with 50 men
