Related fact: the first Goodyear blimp was a repurposed ex-Navy submarine hunter, that likely had a MAD device fitted. You can see the restored gondola from it in the New England Air Museum.
- nradov 2y agoMAD has fallen out of favor. Detection range is very short so it really only works when the aircraft is low and the submarine is shallow. There are techniques to greatly reduce a submarine's magnetic signature. The P-8A doesn't even have a MAD built in.
