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.
