Also take into consideration, in 1941 according to some sources only 25 of Soviet fighters were modern, all others were I-16 or I-153. According to same sources, around 2000 soviet planes were destroyed on the ground. And just for comparison. For example Slovak fighter in 1941 didn't accumulated to much kills in 1941 while still flying on bi-planes B-534 but after change to Bf-109 they were able to do so.
Other side of the coin is, if Soviet advanced just 150 miles in first big operations, they bombers (Pe-2, Tu-2) would be able to easily reach factories in Silesia, Prussia, Protektorate and Slovakia. But fall of the Romania would be probably enough to considerably cripple German war effort. So LW would be flying much less sorties and Soviets would gain same superiority as they gained in 1944/45. And I can imagine rising resistance in some occupied countries, maybe even Poland, as Katyn would be not known. 150 miles means Soviets will get behind Visla, "liberate' Warsaw, conquer huge parts of Romania, Hungary and Slovakia. Even Wienna Me factories would be close enough for Soviet bombers. Masses of Soviet il-2 attacking German reinforcements. Losses would be high? Who cares? Attrition rate would be always worst for Nazis. Between July and August 1943 LW lost around 1000 planes on the eastern front. Sure Soviets lost much more, but they could handle it. If something like this happened in 1942, + surprise attack, LW losses would be much worst. So I don't thin Nazis will gain air superiority over advancing Soviets. Maybe localy but it is not going to help them. And btw till 1942 even light AA defense of the Soviets army could get better, They would have plenty of T-26 anf BT to built on. Sure there would be plenty of Soviet planes shoot down, but Stalin don't care. And plenty of Hartmanns would be later after war able to tell their stories, how good fighter pilots they were. Well, they were, but it was not war winner.
