The second half of the 20th century was marked by the confrontation of superpowers. It went on land, at sea and in space, but of all the fronts of the Cold War, the submarine was the "hottest"... The collection is dedicated to distant ocean voyages and the combat service of the ships of the domestic fleet. It provides little-known, and often inaccessible to the general reader, information about secret campaigns and the participation of Soviet ships in local conflicts. The authors of the collection personally took part in them, being in command positions.
