More than half a century ago, our Motherland, together with its allies, triumphantly ended World War II. The Soviet Navy also contributed to the cause of the common Victory. The assessment of his activities has always been unambiguous. This encyclopedia is the most complete publication devoted to Soviet surface ships during the Second World War, and has no analogues both in Russia and abroad. For the first time in Russian literature, not only the tactical and technical elements of the ships of the Great Patriotic War are presented here, but also the characteristics of navigational, artillery, mine-torpedo, anti-submarine, radio-technical, aviation and chemical weapons, as well as optical surveillance and communication equipment are presented.
