Later in 1936, seven more Tarina class battleships were ordered, they were Vilstermann, Malatov, Romotov, Galland, Daitov, Hermann and Kuikov. They were all built to the 1934 variant.
However as time progress, these ships needed to catch up so in 1940-1941, all the Tarina class battleship were modernized which tripod mast replacing their lattice masts for the forward superstructure. The rear superstructure basically had the lattice removed and had hollow steel pillars in their place. Radar was also installed on the warships. Also two additional dual 5 inch gun turrets were installed. The battleships' hull were transformed so to fit torpedo bulges.
