"Project 69-I" ("Importnyi" – Imported) modified the two ships to use the German guns, even though they still lacked data for the turrets and their barbettes. The detailed design was supposed to be completed by 15 October 1941, but it was rendered moot when the Germans invaded the Soviet Union in June. Neither ship had progressed very far at that time and both had been damaged during the war, so they were ordered scrapped on 24 March 1947 after some thought had been given to completing "Kronshtadt" as either an aircraft carrier or a mother ship for whalers.
