I have read many of Viking's (and others) very informative various Luftwaffe technical what ifs, usually debated on their own. But what if MOST of them would have happened, like the Ju-89 and or Do-19 pursued further at least for maritime work, the Me-210 working the first time, He-177 working, Ju-288 and Jumo-222 being more or less on time, BMW and Bramo joining earlier (or perhaps not at all?), DB-603 and Jumo-213 given the required priority, same with jet engines and jet fighters and bombers which will start to be significantly deployed in 1944, V1 being ready earlier, and so on and so on, PLUS having a better manager in charge of aircraft production, this being the well known Udet dies in 1936, Milch is in charge TL.
Suppose the germans build approx 10,000 aircraft in 1939, aprox 15,000 each in 1940 and 1941, approx 25,000 in 1942, then aprox 35,000 in 1943 and 50,000 in 1944 - yes, i am fully aware of the argument of resource and manpower limitation (would there be a manpower limit given the wide use of slave labour happening in OTL though), but more aircraft built before the war means more exports possible to acquire the necessary resources, while during the war of course more aircraft should translate into more success and later reversals, thus keeping the available resources zones under control for longer.
So how would things go then in WW2, and how would Luftwafe look by mid 1945? How much of the above is reasonably likley of being succesful anyway, as for instance i think i have read that Milch wanted to kill the He-219, did same with He-280 and Heinkel's first generation jet engines etc. (so he didn't liked Heinkel?)
Now i would also add to all this a similar ATL for the much ignored Regia Aeronautica and the italian aeronautical industry of WW2, but details are more scarce about such a TL at least for me, did they had someone who could be their counterpart to Milch and who could do the best of the resources available, could they have say double their production by 1944, building by then say 30,000 aircraft and of better quality in instead of 13,000 OTL, and making better use of the tech provided by the germans? I have read about things like Balbo wanting to switch to all metal constructions in the early 1930s, or negotiations for B-17 licence with the americans (!?) before the war. What if they avoid the Ba-88 and SM-85 fiascos, sticking with biplanes for far too long, wrong conception of their MC-200 and G-50 etc. etc. (i'm thinking of the humped appearance which decreased performance greatly, accepting the inherent poorer visibility as most other contemporaray monoplane fighters of the day, they would have been sleeker and faster machines even with the engines available)?
Pertinent comments/ideas are most welcomed.
