Kursk sank to a depth of 100 meters in the Barents Sea, the B-1 was lost in a part of the Norwegian Sea that is over 1000 meters deep. As hard as it may sound, the VMF and the Admiralty had certainly other priorities than to search for a single submarine that was reported missing - about 100 Soviet and 76 British submarines had been lost during the Second World War.

In your first post of this thread you asked about any updates from British archives about this incident. Bruce and I provided the latest historical findings from primary British and German sources about this event, but you keep speculating vaguely about something I still don't understand. If Fisanovitch sent radio messages about his concerns to VMF it should be possible to find them in Russian archives to know what he worried about.
