It's a FLANKER variant, as already suggested, probably one of the more recent versions, poss Su-35/37 - certainly not the bomber variant or the navalised one. The real freaky move where it stands on its tail before pitching forward is, I believe, the 'cobra' and was the initial party piece of thrust vectored aircraft when they first appeared on the scene.
Just think what could have been - ditch Typhoon and buy 232 Flankers, figher and bomber variants, preferably with licensed production over here with western avionics. Fraction of the price, rugged and relatively simple to maintain. My god, what a platform that would have been.
