The Most Brutal Underwater Weapon of WW2

PO1 William "Chip" Nagel good day Brother William, always informational and of the most interesting. Thanks for sharing, have a blessed day!

A memory jogger. Back when I was in B-52s our wing had an anti submarine mission that we flew a couple times a year. Part of the training for that mission included the history around FIDO. I've got to think that what we would have dropped was an updated version of that weapon.

Do you know the story of the English female sailors who helped to create Atlantic convoy SOPs?
