However this did not help either ship as they attempted to provide fire support for the defenders of Leningrad. had her bow blown off and was badly damaged by multiple bomb hits in September. The former was sunk, but later raised and became a floating battery for the duration of the Siege of Leningrad while the latter spent over a year under repair, although this was lengthened by subsequent bomb hits while in the hands of the shipyard. Both ships bombarded German and Finnish troops so long as they remained within reach, but Oktyabrskaya Revolyutsiya did not venture away from Kronstadt for the duration of the war. Parizhskaya Kommuna remained in Sevastopol until forced to evacuate by advancing German troops. She made one trip to besieged Sevastopol in December 1941 and made a number of bombardments in support of the Kerch Offensive during January–March 1942. She was withdrawn from combat in April as German aerial supremacy had made it too risky to risk such a large target.

Both were reclassified as 'school battleships' (uchebnyi lineinyi korabl) in 1954 and stricken in 1956 after which they were slowly scrapped. There were several plans (Project 27) to reconstruct Petropavlovsk using the bow of Frunze, but they were not accepted and were formally cancelled on 29 June 1948. She was renamed Volkhov in 1950 and served as a stationary training ship until stricken in 1953 and subsequently broken up. Frunze was finally scrapped beginning in 1949. Imperatritsa Mariya class The Imperatritsa Mariya-class ships were the first dreadnoughts built for the Black Sea Fleet. All three ships were built in Nikolayev during World War I. Two ships were delivered in 1915 and saw some combat against ex-German warships that had been 'gifted' to the Ottoman Empire, but the third was not completed until 1917 and saw no combat due to the disorder in the navy after the February Revolution earlier that year. was sunk by a magazine explosion in Sevastopol harbor in 1916. , having been renamed in 1917, was scuttled in Novorossiysk harbor in 1918 to prevent her from being turned over to the Germans as required by
