Petropavlovsk (Петропавловск) was the lead ship of the Petropavlovsk class of pre-dreadnought battleships built for the Imperial Russian Navy. Petropavlovsk participated in the Boxer Rebellion, and during the Russo-Japanese War was the flagship of the First Pacific Squadron, taking part in battles against the Imperial Japanese Navy. On 13 April 1904, the battleship was sunk after striking two mines near Port Arthur. 652 men and 27 officers died, including the Vice Admiral Stepan Makarov and renowned war artist Vasily Vereshchagin. The loss of Petropavlovsk and Makarov greatly hindered the Russians in the war

Battleship “Marat” was considered a symbol of the naval power of the Soviet Union.
She was the most-described and filmed ship of the Country of the Soviets. In her 40-year service, rich in events, she survived four wars, but only in one of them – the Civil War – she used her main guns in an engagement with enemy warships. Only once in her career. In other conflicts, she served as a monitor rather than a battleship, shelling mainly land targets and carrying out counter-battery fire. At the end, she fell victim of the destructive power of German dive bombers. From that moment, she was a battleship only on paper. Mutilated and devoid of propulsion, she was still biting at the Germans from her remaining guns, and after the war, young pupils of the maritime craft appeared on board.
