To prevent a possible advantage of the Turkish Fleet over the Black Sea Fleet during World War I, the fourth dreadnought of the Black Sea Fleet, Imperator Nikolai I, was laid down in the city of Mykolaiv in 1914. The initial armament composition of the ship was revised to speed up her construction—it was planned to mount 305 mm guns on the battleship instead of 356 mm ones. The ship was launched in 1916; however, further work was halted due to a lack of the required mechanisms and equipment. The Soviet authorities renewed their plans to complete the battleship construction in the 1920s, but they were never fulfilled.
