mark,

As I wrote I think that you greatly overestimated the PoW impact.
In real world, there iare frictions.
Even if 1900% of documents were recovered (and I think that 50 to 66% would be much more realistic) not only they could not be translated and processed very quickly but also they wopuld raise huge questions insibe both Japanese and German military establishments.

I don't think the German industry could produce in numbers centimetric sets before summer 44.
In OTL the total production of Berlin sets (both for LW and KM) did not exceed 80 sets...This is important because RLM Radar experts HAD understoood the potential of centimetric radar by summer 41 (BEFORE the PoW sinking in FFO) but the German industry was unable to produce magnetrons even using, from 43 on components of recovered allied magnetrons (from the H2S radar mainly). The scenario of a Greek Bodenplatte is completely unr ealistic by September 42.

About the Me-262. The problem is not just metals, it is the design of the centrifugal supercharger regulation. BMW was more advanced but refused to share its knowledge with Junkers (this is why the French post-war ATAR jet engine was developed from the BMW and not the Jumo design by the way...)

About Pz-IV:
The Wehrmacht discovers the T-43/KV-1 by May/June 42. Production of kits could not begin before August.
With the huge offensive planned for Ukraine Rommel is not to get may be 20 to 30 kits before October 42 at best.
