Operation Ivy Bells | DoD

In 1970, Captain James Bradley had a daydream - a daydream that inspired one of the most audacious aquatic espionage missions of all time.

Operation Ivy Bells gave the USA unprecedented access to Soviet undersea communications cables, and hastened the end of the nuclear stand-off between the two nations. Sophia Di Martino joins journalists Christopher Drew and Sherry Sontag for a thrilling and often claustrophobic tale of covert submarine warfare.
