Would it have been economical for the Soviet Union to build an interwar line of heavy cruisers derived from Rurik II?
Short answerProbably not. The necessary industrial infrastructure would make the idea uneconomical, even though the Soviets would continue pursuing other cruiser types.
NotesA recurring heavy-cruiser design would still require the industrial base to produce it. Building that capacity would cost the interwar Soviet Union enough to make a Rurik II-derived line impractical. Soviet experimentation with other cruiser types would continue, so the objection applies to this proposed lineage. The scenario turns on shipyard and industrial readiness as well as hull characteristics.
