[Oktoberfest]

About torpedoes launched to tons sunk, the problem would be for the americans at the early stage of the war till late 1942, when their torpedoes had very poor reliability compared to those of other nations.

I remember when the first silent hunter came out I've read an article about how they had problems with torpedoes sinking to low and going under the target, or hitting but not detonating, etc...
