A modernized version of the MK-6 cruiser project with gun mounts from the 1940s replaced with more contemporary ones—the main battery is represented by BL-109 guns instead of MK-18, and AA mounts represented by ZIF-31 and 4M-120 mounts instead of 66-K and 70-K, respectively. The project reflects a potential upgrade of the cruiser, which might have been carried out in the 1950s.
