there is only one problem with this strategy.
the UK can build its Navy in a SZ that is 3 spaces away from your Fleet build
If you build fleet in the baltic, and put all your fighters in Norway, then UK can build in SZ8. if you put the fighters in France, they build in SZ2. if you split them up, you can’t kill a good UK build.
This means that the UK actually gets 2 turns of Navy builds before you can try to attack their new navy. Yes, you can win and sink their navy, but can you really afford to kill 60 ipcs of UK navy? What is the cost of German IPCs to kill that 60 ipc UK navy? Don’t count your subs you start with, they are made for this after all and you can’t turn them into ipc. Only count what you are purchasing as navy or losing as planes. I do not think it is worth it, and you will have a Russia owning Norway, Karelia, Western Russia, BeloRussia, Ukraine, and also one of either the Balkans or Eastern Europe.
Points for originality, and you should give it a shot, but I just do not think it is feasible (at least not without lucky rolls)
if i’m not mistaken you can non-com the 2 baltic subs to be within reach of any of the seazones (you also might have that 3rd one alive if you get lucky) and that should enable you to get atleast 4 fighters (2 could land on carrier) a bomber and 2 subs to attack and the uk will have 2 destroyers a carrier and 2 fighters (plus the russian sub or crusier). Thats not that great a set up, but you really just need 4 hits (and you should average more than 3 on the first round) so you kill the carrier and then you can just retreat. He should hit you slightly over 2x so you kill your subs and maybe 1 of your 6 fighters if he hits you that 3rd time and blam, no more uk navy and now w/e navy you bought round 1 is moved out and capable of striking any uk sz and your med bship might even get to link up.
