How many of the Lost 52 have been found so far?
An interesting video game related to this is silent hunter 3.
It's a German u boat simulator.
They did their best to keep it historically accurate.

Yeah ... Getting them to go boom reliability never really happened. They just improved.So the Germans had issues with their torpedoes that the USN did?
