Russia's SU-35 seems to be a world beater. Now that supposed stealth invincibility is being rapidly degraded through new technology counter-measures, you have to wonder how a marginal performer like the F-35 would fare against the Russian jet? Actually you might try to figure out how long the F-35 would last.
I've seen a lot of jet fighters going back to the F-86 Sabre and the CF-100 and pretty much everything since but I have never seen one that performs like the Russian SU-35. To the Sukhoi, a flat spin is a maneuver, not a lethal emergency. Here's the Russian jet at this year's Paris Air Show.
