I was just wondering if this mod changes how the game handles the defective American torpedoes? The Mark 14 torpedo was really bad and had like a 50% failure rate. The problem wasn't fixed until September 1943 I think. They had three major defects that had to be found and fixed.

It shouldn't be easy to fix. Should probably require Political Power and Navy XP and be in three stages.

There was also a torpedo shortage.
