You baptized the yak fighters flying tanks.All your claims are based on the unproven assumption that soviet archives are perfect
Definitely, the Soviet archives are not perfect. However _you_ have to proof, whether the imperfectness does not allow to draw conclusions on particular topic.
Soviet union never officially publiced a list of her casualties
Because the problem of Soviet causalities is much more complicated than it seems. Anyway. the problems of Soviet causalities and of the accounting of losses in the Soviet Air Forces are quite different, that should be considered independently.
Soviet union massively manipulated the lists of German pows perished in gulags
Could you please give an example?
What your russian archives report about katin?
Have you read the collection of Soviet archival documents on the execution of Polish prisoners? I have.
Do you know the soviets c
Do you know that soviet officers were execu for battle defeats?
They were tried and executed not for losing battles, but for the loss of control over the troops, cowardice and disobedience of orders. If we are talking about the top officers of the beginning of the war (Pavlov, Klimovskikh, Oborin, etc.), of course, they became scapegoats for Stalin's miscalculations.
For defeats, generals were transferred to lower positions and sent to command reserve units.
Aircraft designers send to Siberia for under performing aircraft designs
Could you give an example please? I have the opposite information - many convicted designers and engineers were released from imprisonment (in particular - from prison design bureaus). I am not aware of any cases when during the war they were shot for insufficient characteristics of armaments (before the war - known, but more likely for failure to meet deadlines).
All you do is to give personal statements that soviet archives are serious
They are very serious, but very closed. Even Russian researchers do not have access to all the archival materials. The declassification process was slow, something is processed and published even now. But I think most of the documents from the war will not be published in the next 50 years. Or maybe even 100. But i still keep a hope that at least in some cases the available information will be enough to restore the truth. In particular - to verify the enemy's claims.
Why nobody in soviet era,for 50 years, did not use these archives ?
Because in the Soviet era, these archives were only available to researchers from military academies. And they wrote dissertations, articles and monographs that were classified. Some of these became available in recent decades (I have scanned copies of some of these publications), but the Soviet system did not allow too truthful publications even under these conditions.
You never worked in the Soviet archives, but you assert indisputably that they contain false information. This is hardly a constructive approach to discussion.
