8. Operation Ivy Bells (1970s)
Operation Ivy Bells embodied the covert technological battles of the Cold War era. U.S. Navy divers, working in complete secrecy, tapped into Soviet underwater communication cables in the Sea of Okhotsk, gathering invaluable intelligence. This operation showcased not only the lengths nations would go for information, but also the ingenuity required for underwater espionage. Ivy Bells remains a prime example of how technology and secrecy intersected in the superpower rivalry.
