#two seats Su57
forest blade
Why? We already got the one seater
kind trellis
I dunno, maybe it could be a skin for the one seater Su57 or even better, the two seater will have some features that the one seat don't have, for example the two seater could be a better jet for electronic warfare while the one seater is only for air superiority and SEAD/DEAD operations.
of course the two seater will have super maneuverability but a bit worse than the one seater, instead in BVR it could be better than the one seater as it will have better technologies such as better radar jammer and better avionics such as radar and communication and even drones wingman that cooperates with the two seater Su57
