90 years have passed since the Russian icebreaker steamship first passed the Northern Sea Route in one navigation. How close have we come to fully mastering the northern route? What historically directed Russia to the North? We will find out about this by going on an expedition of 3 at once on the nuclear icebreakers "Vaigach", "Ural", "Sibir", we will meet the "ice captains" and their professional teams.
