If Stalin received a French-scale fleet in 1938

What changes if Stalin receives a fleet comparable to the French Navy in 1938?

Germany could lose freedom to deploy capital ships for raiding, while Japan would face a stronger Soviet maritime threat and Stalin would gain useful smaller warships and submarines.

A Soviet fleet equivalent to France's in 1938 would create new problems for both Germany and Japan. In the Baltic, the threat could tie down German capital ships and restrict their availability for surface raiding elsewhere. Japan would have to consider the Soviet force in the Pacific. The answer also stresses the additional cruisers, destroyers and submarines, rather than treating the change as only a battleship question.
