In 1939 theoretically B-135 could be entering service. Especially with bigger military/ economy behind the orders. OTL B-35 (not rectable gear) flew in September 1938. After Munich everything was downgraded but B-135 with retractable gears flew in 1939.Oh wow, I really like that. What was that model called? Would it be mass producible by 1940? I think Hurricanes would arrive to supplement the air force before these fighters can enter mass production. In this scenario the ones that went to Finland would have probably been more useful to the AH's and Poles. I know that PZL had prototypes and designs for contemporary monoplanes by the time of the invasion of Poland.
As for the B-534 I meant no disrespect. It was probably the best biplane fighter ever produced, I was using the BF-109 E as a benchmark for obsolescence, so really only considering low wing monoplanes. In experienced hands I can imagine the B-534's agility causing trouble for 109s and it'd probably still give the 110 a run for its money.
I think the K.u.K would be fascinating in general with squadrons from all over the empire, but probably dominated by the Czechs who would probably specialise in aviation. I believe they were already license building Amiots in 1938 so not a stretch to see them take on other French designs either.
Hm, as for the oil supplies, I considered getting the USSR involved in Poland, but in this scenario with Poland better able to resist and another ally in eastern Europe the Allies would be unable to admit anything other than being at war with the Soviet Union, and I think that the USSR and allies probably would have little appetite to have to commit to a full blown war with each other. Also, I think that the Nazi hatred for Russia and Communists might be a road block for a long term military alliance. What do you think?
I just imagine Romania to be trying their hardest to stay neutral and appease all sides as they did in OT in 1940. I think they'd probably have more sympathy to Poland and AH despite old grudges with the latter and might have more leeway to assist in some way without committing to war. All it'd take would be for the Ussr to join Germany and strategically Romania would be done for.
As for A-H markings, that would make for some interesting illustrations.
As to B-534, Slovak B-534 shot plane down in 1944 and Slovak used them in USSR in 1941.
109Es would be only entering production/ service in September 1939, wouldn’t they? Majority would be B, C, Ds.
Czechs were license building Bloch MB-200. Waste of money in my opinion and in 1938 started to built Soviet SB-2s. However Potez as well as Blenheim were considered and Czech Aero A-300 prototype was built in 1938.
Yes, OTL Poland and Romania were allied in defense against USSR.
Also wouldn’t borders with Germany be fortified as OTL Czechoslovak? With Czech-Austrian internal border being not issue A-H would have much bigger reserves. Especially with addition of Polish front German would be hard pressed to really advence so much as you described.
OTL they were planning to pincer Czechoslovakia from Vienna and from Silesia. And Czechoslovaks had some mobile reserves for this. Here border is much shorter and mountainous.
Honestly I think A-H should be doing much better. Especially if Romanians are indeed not belligerent towards A-H.
