I was intrigued by this image, that brought me to wonder if and how much this was true.
Actually, it has precise reference:
although not for A-1 variant, and finds a good match in Chris Goss' book:
whose bottom photo undoubtedly shows a FW 190A-1, without MG 151/20 protruding from wing root and no cooling slots on engine cowling side. While previous photo may be arguable:
since showing engine cooling lattice, which could belong to an A-2 or higher variants.
Same book states that FW 190 JABO attacks started on 7 July 1942, so could have involved variant A-2, but what about its predecessor, the A-1? It looks there's no evidence, but if so, why to have an /U1 subvariant? In addition, I think to recall that JABO capabilities where already given to latest Bf 109E, performing attacks against RAF airbases, so why discontinuing this practice?
The question is: did early two variants of FW 190A perform JABO missions against allied targets during 1941-42?
Thanks for any help.
