I want to focus for a second on the Baltic. Just a military digression from our current discussion of France, but I feel it's worth discussing.
The Soviet navy is a shadow of the Imperial armada. It is unpopular at the moment, being liquidated bit by bit, and lacking much of the heavy numbers that made the Tsar's fleet imposing. It also has three battleships, and a metric ton of lighter ships that will mess up our fleet. Furthermore, we cannot really counter this heavy force with force of our own-it'll take years to get a fleet half the size the Ruskies have going. The Russians also have a sub fleet, which is rather distressing. All in all, the Russians will always win on the open seas, with the exception of the miracles of RNGesus. And there isn't really a way to counter them with bigger guns and tougher hulls. But we can counter them.
In 1918-1919, the British launched a naval campaign, with the aid of the Baltic countries, to hinder Russian naval operations in the Baltic. On August 18, 1919, British motor torpedo boats, with aerial support from a carrier, attacked the Russian naval base at Kronstadt, during nighttime. The aircraft were inconsequential, but three boats- CMB 88, CMB 79, and, CMB 31, found success. Under heavy fire which killed her captain, CMB 88 sank the Gangut class battleship
Petropavlovsk, while the undamaged CMBs 31 and 79 sank another Gangut and the submarine depot ship
Pamyat Azova. All in all, the raid lost three boats, and sank three capital ships.
If we are to have a navy worth a damn vs a Soviet menace, we ought to replicate the British success. MTBs are fragile, and their undersea counterpart U-Boats are countered both by destroyers, and we can't make a navy entirely ought of them, of course. We still need destroyers for escort and cruisers for intermediate tasks and long-range operations. But MTBs and U-Boats, are a very much useful tool to have in our inventory considering the Soviet fleet makeup, and destroyers have their weaknesses, not being able to protect port raids, for instance. The Soviet fleet is expensive and vulnerable to cheap counterattacks, and we ought to exploit this as much as possible. Modern technology on cheaper platforms is the best way forward if the German navy wishes to fight the Soviets for the time being, seeing as we're in the opportune moment where the torpedo net has been obsoleted due to speed, but the Soviets have older ships without torpedo bulges and belts.
I got this mostly from R.G Grant's
