The lack of afterburner however suggests perhaps much longer wings with a subsonic flight design.
I hope they are working on optimised weapons for these aircraft... I would suspect a KAB-50 would be ideal from high altitude using laser homing, perhaps combined with satellite navigation to give very high accuracy. Very high accuracy would mean the combined high kinetic energy with a fairly decent HE capacity of 50kgs of HE should make it a very effective weapon able to destroy a vehicle without destroying the whole block. Equally it is a fairly small compact weapon that should be able to be carried in large numbers.
