More of the plenty of vessel choices below destroyer size including an Sch type sub. We have a top heavy Russian fleet in conflict with actual historical use.
Hopefully others with more knowledge can come up with some suggestions.
Edit: Just seen nrnstraswa's suggestion of this in another thread which I like the look of (good picture too):
Sukhoi Su-2 - Early-war Soviet light bomber: used for reconnaissance, bombing runs, and was even used as an emergency fighter against superior German aircraft.
I'm all for more early war aircraft across the board and less fighters.
Destroyer Zhivuchiy, ex USS Fairfax - Best of the lend lease Wickes Class
Planes Su-2 - Soviets need a cheap dive bomber, with possible emergency fighter abilities. If a Soviet Carrier makes it through, SU-2 would be a great option Beriev Be-2 - Weak fighter, but seabasing and spotting ability A-20 Havoc - Important LendLease bomber, sunk the Niobe and knocked Z-39 out of the war.
Other Izmail - Can we finally get this battlecruiser a card. Been a very deserving choice for some time Frunz Carrier Conversion - Most sensible and realistic Soviet Carrier option. Shch 307 - Costal class not yet represented, sunk U-144 with a torpedo Kommetrin/Marti - Either as an option for a forward placed mine layer. Kommetrin a bit better armed and armored. Chapayev - Launched but not finished till after the war light cruiser.
A-20B Havoc Patrol bomber - Thirded. Soviets used them for low level attacks on German convoys.
3)Other Units:
Izmail BC - second squint's nomination S-101 submarine - It torpedoed and sank U-639. It's a smaller coastal type sub we don't have for the Soviets yet.
The IJN Carrier Liberation Force - "Because We Care" Join the IJNCVLF. Service Guarantees Citizenship!

S-101 is the same class as S-13. Saw that an remembered to add the Shch-307, which as well sunk a German sub with a torpedo.
