Keeping up with the Soviet narrative, here are a few ideas. Assuming if they only get 3 slots and we stick to histroical units
SU-2 Cheap early war bomber that was sometimes used as an emergency fighter. Lembit Survived an barrage of 50 depth charges. Dubbed the Immortal Submarine Komintern or Marte Last 'large' ships that fought in the war. Very unglamorous, slow 1 minelayers.
If the Soviets get more than 3.
IL-10 Late war dive bomber. L-3 Very Successful mine laying submarine.
And for straight fantasy.
UP-41 Battleship. Designed for by the Italians, similar to the Roma Class. Frunze 4th Gangut class Battleship. Gutted by fire in the 1920s, was considered to be rebuilt as a 'fast' battlecruiser. One of the turrets would have been removed. Either the Fruze or Izmail Carrier Conversions. Su-2 and LL hurricane operations.
The Canadian prince henry could be an option for this, not sure on the date though. I think the UK have more pressing Aux choices but the US is an option.
