This looks interesting although I do get tired of every sub game being based on German boats U-Boote. SH4 was the exception but they eventually added one to that in the end.
That is because the Germans were and are the masters of "U-Boote".
My grandfather, who served in Kriegsmarine, said: Yay, the Italians... but you can never rely on them - as we found out the hard way (1943 he meant).
Reason?
Easy: Simply follow how embarrasing every encounter of the US Navy NOWADAYS still is with German U-Boote:

"In March 2013, U-32 crossed the Atlantic Ocean in order to join exercises on the east coast of the United States. During the journey the U-Boot remained submerged for 18 days, the longest time any German submarine managed to do so, yet."

But this ancestry/heritage/legacy is part of the miracle, the fun...
