This publicity photograph shows crew members of a Soviet submarine, including an officer (right) while their vessel cruises on the surface.

Throughout the Cold War, Soviet submarines posed a significant threat to the North Atlantic Treaty Organization (NATO), its warships, and the North Atlantic convoys that would have been required in the event of war. Post-1945 developments, including nuclear-powered submarines with longer-range torpedoes and submarines carrying anti-ship missiles, presented an even greater danger than had German submarines during two world wars.
