In the undeclared 40-year "cold war" in the seas and oceans, dozens of Soviet submarines carried out hundreds of campaigns in designated areas of the World Ocean. The crews were subjected to significant physical and moral overloads, and the equipment did not always withstand. In the context of a tight campaign schedule, there were cases of sending ships with malfunctions to the sea with crews that did not undergo proper training... As a rule, this got away with the commanders and chiefs who remained on the shore. But sometimes it ended badly or very badly for both the ship and the crew... and the bosses who sent them to a deliberate risk subjected the survivors to military "justice." The author of the book is Hero of the Soviet Union, submariner, Vice Admiral E.D. Chernov talks in his documentary story about duty, courage, conscience and responsibility, about the disastrous consequences of impunity and careerism brought to the Soviet fleet in the late 80s of the last century.
