as you can see all very experienced units and put them up against your much lesser experienced units and I would think that would have an effect on the outcome. I know your typhoons and spitfire mark V's cant have much more than 20-30 xp, since you recently teched up to them.
Now some hints to help that I have learned the hard way.
first never have your fighters escort bombers on a attack unless you absolutely cant help from doing that. Always send in fighters on recon until the defenders fighters stop intercepting then send in your bombers with a small escort maybe. I have found that escort fighters always take huge losses. If you have been following my air attacks on you with the history tab then you may have noticed that when I send in my bombers they are almost always alone. Now to send in enough fighters on recon you have to build fighter units with 6 or more fighters in them just for this purpose.
another hint
look closely at your Hawker Typhoons and you will see that they have excellent strike abilities in fact they are as good as my Stukas. Build a couple units of just them for ground attacks and you have a unit that is all fighters and capable of nasty ground attacks. then send those units with some spitfires to do air strikes and you will find that they do a lot better and take less losses because they have no bombers to try and defend.
and the other thing i have found is that fighters do much better when defending then attacking (you will be able to defend Britain fine) so I have grown to expect higher loses when i attack and try to make sure I limit those loses. The key is recon missions I feel like that's the way they can attack the best with less losses. I have a couple more tricks i do but i cant tell you everything or you will kick my butt [:D]
so to sum it up
you where up against my best pilots.
you where trying to fight them and defend bombers at the same time. <---- the main reason for the high losses from my experience.
and the HQ unit had some flak to assist my fighters.
here is a look at the battle from my history
I hope this helps bro and maybe grumpy can shed some light on the air combat from a designer point of view.
