So how did we get the designs comrade?
Weelllll, tovarisch, we hacked into lockheed martin and stole all the plans we could find. We then got drunk and put together the bits we thought were sexy.
This is the result?
Da.
Well done, have 50 roubles..
It looks like it has alot more similarities to the Su series it is to replace than any current US design, in fact there really isn't many similarities it shares with any of them (except some superficial commonalities with th YF-23). But if it helps the masses cope with a threat to their air superiority, then sure: it was the brainchild of a bottle of vodka and some stolen plans
