Her turrets were modified to use a fixed loading angle of 6° and fitted with more powerful elevating motors which increased their rate of fire to two rounds per minute. Their maximum elevation was increased to 40° which extended their range to and they were redesignated as MK-3-12 Mod. She landed her old 'Lender' AA guns and replaced them with six semi-automatic "21-K" AA guns, three atop the fore and aft turrets. Three 34-K each were mounted on platforms on the fore and aft superstructures as well as a total of twelve DShKM machine guns. Her fire-control system was completely revised with a pair of KDP-6 fire control director, equipped with two Zeiss rangefinders positioned atop both superstructures. Her original Pollen Argo Clock mechanical fire-control computer was replaced with a copy of a Vickers Ltd fire-control computer, designated AKUR by the Soviets, as well as a copy of a Sperry stable vertical gyroscope. She also received the first stabilized anti-aircraft directors in the Soviet fleet, SVP-1s that were fitted on each side of the forward superstructure. They were manually stabilized and less than satisfactory as the men manning them had difficulties keeping their sights on the horizon while the ship's motions were violent.
