Even 1925 and they had fears about the new ones being "unreliable".:lol:
Unbelievable that 50 year old designs are used even though new models were made and equipped. Someone spent time and money on R&D, building, equipping, training and testing with new torpedos and in the end the submarine commander is like "No, we'll use the old ones. They're better."
