In 1976, after repeated sonar anomalies and crew reports from Northern Fleet submarines, Fleet Admiral Nikolai Smirnov ordered establishment of a confidential analytic section inside Naval Intelligence. Weekly digests summarised sightings, acoustic traces, and instrument failures for the Commander-in-Chief. The working circle drew on the Oceanographic Commission of the Academy of Sciences and inherited logs dating back to 1950s.1

By 1990 the analytic cell had catalogued more than twelve thousand naval cases—half involving oceans, one sixth large lakes. Though funding ended with the USSR, veterans continue to brief Russian Geographic Society and release material to civilian researchers.9
