No air force for Germany??? In my games I would get just killed if I tried this. I always get a bit overwhelmed initially when invading Russia, but if I have keep a good tech lead, I eventually gain the upper hand, and actually start destroying their inferior planes. (the ai keeps using them even when org is very low, giving an opportunity to completely destroy). How many actual squadron's do you build. I aim for (with my 5 limit) 30 intercepter, 15 fighter, tac, and cas, 10 nav and 5 transport. 3x5 of the interceptors stay in France/Germany to minimize the allied strategic bombing raids, and the rest are for Russia.
My usual Germany-strategy:
- annex Denmark in 1938, build naval bases in Greenland and Iceland
- construct 150 submarine units
- land army focused on motorized and tanks, some infantry. AA-brigades to protect from air attacks
- plaster Western Europe with serial builds of flak. I always keep a reserve and deploy it where the a.i. strikes. If the a.i. strikes province x and repeats it, I'll deploy 10 levels of flak there. Flak alone will deal with the Allied bombing campaign.
- my air force is something like this:
4-8 interceptors, 4 fighters, 4-8 tac bombers, 4-8 nav bombers, 2 transport planes.
I completely ignore CAS (saves a lot of research as well), since CAS has too low of a range. My air force is enough for every pre-Barbarossa campaign, even for a potential Sealion (done it several times).
In Russia I gave up winning the air war. The cheat events used to gift Russia tons of air wings and their airforce is too huge and too modern anyways. It should be crap until 1944.
I hate air warfare anyways. In Russia your fighters don't have enough range and if you deploy them to conquered airfields, it takes months before they've reorganized enough.
It's usually easier to simply go for AA-supported land forces and destroy the Soviets in huge encirclements. I only use air strikes in local breakthroughs.
