 Sevastopol ( Russian : Севастополь ) was the first ship completed of the Gangut @-@ class battleships of the Imperial Russian Navy , built before World War I. The Ganguts were the first class of Russian dreadnoughts . She was named after the Siege of Sevastopol during the Crimean War . She was completed during the winter of 1914 – 15 , but was not ready for combat until mid @-@ 1915 . Her role was to defend the mouth of the Gulf of Finland against the Germans , who never tried to enter , so she spent her time training and providing cover for minelaying operations . Her crew joined the general mutiny of the Baltic Fleet after the February Revolution and joined the Bolsheviks later that year . She was laid up in 1918 for lack of manpower , but her crew joined the Kronstadt Rebellion of 1921 . She was renamed Parizhskaya Kommuna after the rebellion was crushed to commemorate the Paris Commune and to erase the ship 's ' betrayal ' of the Communist Party .
