In the second edition of the book, the author still considers the explosion of a hydrogen peroxide torpedo and detonation of ammunition to be the main version of the Kursk submarine's death, and provides new evidence to support it, including facts of deliberate concealment by the command of the Russian Navy, the Northern Fleet and the Main Military Prosecutor's Office of unsatisfactory preparation of the ship and crew for going to sea, design flaws project 949A, about which the general designer of the Central Design Bureau "Rubin" Igor Spassky is silent. We are talking about forgery of documents related to the training of the crew at the Training Center for Submariners and the condition of torpedo weapons. The versions of the collision of the Kursk with American submarines, the attack of the submarine by Russian surface ships and land-based missile launchers, which arose or were replicated after the publication of the first edition of the book, are refuted. The pages of the second edition describe the phantasmagoric story of the appearance of the additional resolution of investigator Arthur Egiev, which recognizes almost all the arguments of the defense and calls into question the fundamental expertise of Viktor Kolkutin and Sergey Kozlov. The role of some leaders of the country, the navy and the investigative bodies who determined the fate of the criminal case on the death of the Kursk and continue to hide the truth from society is being reviewed.
