Just finished the book "Thunder Below" by Admiral Gene Fluckey who commanded the USS Barb on 5 cruises during WW2. It was a Gato class submarine. They mentioned having to 'Degauss' the submarine right before leaving Midway (after fuel/torpedo reload) for the sea of Okhotsk. I knew degaussing was a counter measure against magnetic mines but really didn't know how they did it.
Many ships were retrofitted or built with the degaussing generators & wiring on board. The USS Barb was built without it and, from what I understand, had to degauss every 6 months. I still don't understand the process, not much info online.
