The Submarine That Tapped Soviet Deep Sea Cables In Complete Secrecy

Four hundred feet beneath the freezing, storm-lashed waters of the Sea of Okhotsk, the United States Navy pulled off one of the most daring acts of espionage in human history. Operating deep inside the Soviet Union's most heavily guarded naval sanctuary, a modified American nuclear submarine bypassed surface destroyers, sonar nets, and sub-zero waters to locate and tap the Kremlin’s most secure undersea military communication cables. In this deep-dive documentary, explore the complete, declassified story of Operation Ivy Bells: • The Visionary Gamble: How civilian intelligence analyst James Bradley cracked the search location using childhood memories of Mississippi River cable markers. • The Ghost Vessel: How the USS Halibut (SSN-587) was converted into an underwater espionage laboratory equipped with oceanographic skids and saturation diving facilities. • The Engineering Breakthrough: How Bell Labs and the NSA built a massive 20-foot non-invasive titanium collar to record unencrypted Soviet conversations using electromagnetic induction. • The Ultimate Betrayal: How veteran NSA specialist Ronald Pelton sold the entire operation to the KGB for $35,000, bringing a decade of unmatched deep-sea intelligence to an abrupt end.
