Sukhoi Su-6

Armored ground attack aircraft, overshadowed by the Il-2. Su-6 was more advanced than the Stormovik, its air-cooled engine did not require armoring and provided more power. But Il-2 production was already 'in full steam', and switching to radically new aircraft could be harmful for production rate. Importantly, the Su-6 inherited chronic problem of the Su-4 - it relied on experimental engines.

Development started in 1939. Second Su-6-2 (improved) version was built in 1942, and the last one (Su-6-3), powered by liquid-cooled 2000hp AM-42 started flight testing early in 1944.

Kelly I think I would agree with you that the colour illustration is in fact an the Su-7. As I have stated elsewhere on this site the picture editing policy leaves much to be desired.
Bjorn as is common place with Russian designations the type numbers are often repeated as is the case here, there was both a radial engine Su-7 and the later jet powered model.

Kelly, a Sukhoi 7?? That is a jet my dear boy !

Kelly: All three illustrations are various forms of the Su-6. The radial engine Su-6M.82 was tested in both single seat and two seat configurations, same as the IL-2 and IL-2m, and the Su-6AM-42 was the inline engine version of the two seat Su-6M-82. It is with this latter, inline engine form that we are the most familiar.

I don't think that the color picture, nor the triple-view diagram, presently on this page are of the Sukhoi Su-6. Instead, I think that they are misplaced Sukhoi Su-7 aircraft pictures. The Su-6 looks a lot more similar to the Il-2 Sturmovik...just look at the top photo, which is the Su-6; it has an in-line engine, rather than a radial engine like that shown in the color picture and the diagram.

Do you have any comments about this aircraft ?
