Kharkov air war for May 1942

[Nokose]

According to a Russian book that I read there was little impact (according to Russian records) made by the axis air forces in this campaign outside of the Luftwaffe. It had the 11th as a premptive strike against the Kharkov airfields. Priens JFV 9/III has the III/JG77 being the only German fighter unit in the area with Bf 109 F-4/R-1 (13 195) being 25% damaged by bombs at Kharkov-north. I've checked some of the VVS losses.
