1. Quality of acoustical and radio equipment calibration for waterside security. Historical mistakes
and international conflicts: “Whiskey-on-the-rock” submarine C-363. New documents
Irina Bjørnø and Leif Bjørnø†

2. How all started -L.B archives

3. Map of event from 25.10.1981

4. Сalibration mistake: 100 miles

In an interview in 2006, Vasily Besedin, the political
officer on board, explained the happening . The
vessel had dual navigation systems, a well-trained
crew and the captain Pyotr Gushchin was amongst
the best. On board was staff officer Joseph
Avrukevich who was trained in security techniques.
Besedin claimed the incident was caused by an error
in calculations by the navigation officer due to
miscalibration of acoustical system.

13. Navigation system was hybrid “Dekka” plus “Loran”
Why accidents possible?

14. Map of event

17. International collaboration and open sources platforms will help us to
prevent such crisis. As historical documents were opened and available for
public, the role of scientific collaboration was cleared.
Only together can make our world more secure place to be. We have only
one planet. We all - Human being.
We should learn form the mistakes of past.
