The Russians are now showing their SU-35 Flanker derivative prototype to air force officials and foreign representatives.

Note that, somewhat confusedly, this is the second aircraft designated Su-35.

It will feature a glass cockpit

Thrust vectoring to replace canards and nose strakes on earlier models for high AoA controllability.

The airbrake has been removed, with differential actuation of flight controls now handling the task reducing weight and allowing for more fuel

And the engines have been upgraded to the tune of about 4000 lbs more thrust each.

These changes, along with other weight reductions in the airframe are supposed to, among other things, give supercruise capability, and it is expected to be fitted with some form of phased array radar.

I’m inclined to believe that the supercruise will be meaningful in air to air mode, if just because the aircraft carries so much fuel internally anyway that it will only be carrying 8 or so missiles in that configuration.

I think that the desire for supercruise is what drove them away from canards, likely increased transonic and supersonic drag a bit, though I am not an aerodynamicist.

It’s also has a new fly by wire flight control system, and so I’m a bit surprised that they haven’t reduced the size of the vertical tails a bit to cut down on weight and drag.

It should be an impressive aircraft, and competitive, particularly on price, in the export market.
