The Sverdlov-class cruisers, Soviet designation Project 68bis, were the last conventional gun cruisers built for the Soviet Navy, in the 1950s. They were based on Russian, German and Italian designs and concepts developed prior to the Second World War, but were modified to improve their sea keeping capabilities that allowed them to run at high speed in the rough waters of the North Atlantic. The basic hull was more modern and had better armor protection than vast majority of the post WW2 gun cruiser designs built and fielded by peer nations and they also carried an extensive suite of modern radar equipment and anti-aircraft artillery. This class of cruiser satisfied Stalin's and Soviet Navy leadership's desire to field a ship that was in keeping with a Soviet Naval doctrine that was focused on supporting the defense of the Russian coastline, operating out of naval bases worldwide and protecting Arctic, Baltic, Mediterranean and Black Sea interests. A secondary commerce raiding and political presence mission in the third world was also envisioned for this class of ship. They were considered obsolete by Soviet Premier Khrushchev, who believed they had a limited role in supporting strategic and tactical naval operations during 1955-1967 era, when theories of mutually assured destruction limited their use.

The Soviets originally planned to build 40 ships in the class, which would be supported by the Stalingrad-class battlecruisers and aircraft carriers. This represented a significant risk to the Royal Navy, especially in the North Atlantic. Britain responded by introducing the Blackburn Buccaneer, a carrier-based strike aircraft that had the performance required to approach and attack Sverdlov class ships at ultra low level, using toss bombing attacks to deliver nuclear ordnance, while remaining outside the 5km lethal range of the Russian 100mm/37m gun. When the building program was cut back and the battlecruisers and carriers were cancelled, the Sverdlovs were left dangerously unprotected when operating in areas outside the cover of land-based aircraft. Their secondary mission, operating on their own as commerce raiders was also compromised as they would be extremely vulnerable, in good weather, to USN Carrier Battle Groups equipped with modern strike aircraft and the few remaining Baltimore class conventional cruisers equipped with 8 inch guns. The Royal Navy's few remaining Colony and Tiger class conventional gun cruisers probably lacked the range and speed required to counter the Sverdlov, which was also true of the USN's Gearing and Forrest Sherman class destroyers.
