M. Voznesensky's book is an independent journalistic investigation of one of the tragedies of the Soviet submarine fleet. Under mysterious circumstances, in March 1968, a K-129 missile submarine with a crew of 97 people died near the Hawaiian Islands. The very fact and circumstances of the death of a submarine that had nuclear weapons on board were hidden in the USSR for a long time. But in the West, journalists wrote in detail about what happened. Especially much noise in 1975 was made by an article in the Los Angeles Times, which revealed the details of a unique secret CIA operation undertaken to raise the boat. The book will be of interest to all lovers of the history of the submarine fleet.
