What could the Soviet Union have built by 1939?

At most six of the first eight capital ships would probably be in or near service, after construction lasting at least five or six years.

Two yards, one in the Baltic and one in the Black Sea, initially have the physical space for these ships, with two more nearby sites potentially expandable. The first four hulls could begin there, followed by another four after new Northern and Pacific capacity came online. Construction would take at least five or six years, leaving at most six of the first eight ships in or near service by 1939. The likeliest completion order is Baltic, Black Sea, then Pacific. Pacific construction would require its own industrial support, whereas Northern ships could be left competing for facilities already serving the Baltic and other western projects. Soviet-built hulls, armor, and guns would probably rely on foreign assistance and licensed engines, gearing, and possibly fire control.
