Rash? Fair enough, and that's interesting. I guess that explains the seeming lack of stealth principles, (surface coatings, exhausts, dodgy cowl, etc). And although you might be able to fool a radar like that, I'd hazard a guess that infra-red is a different story?
And can't the F-22 have something similar? There's clearly a lot of secret technology on it - I imagine that's why the US doesn't sell any. Surely there's some secrets that Jane's etc hasn't uncovered?
Ultimately, in the event of a clash between the two, I'd suggest the price-tag/technology level is going to decide the outcome, (as opposed to pilot skill, at least) and would seem obvious that Russia can't really compete on that basis.
Edit: It seems that by using the SU's radars to spoof it's location, it would blind itself to it's enemy's location. Perhaps dogfighting will make a come back...
Edit2: Seems they've lasers to handle the infra-red as well. You can't underestimate those crafty Russians.... (Shane! ). Adrian, I take that back...
