Does production Su-75 keep the reinforcement bar in the belly intake?
S-70 design should be more or less set in stone by now, probably has been for a while now. It's assembled at NAPO in Novosibirsk. Su-57 and presumably Su-75 are and will be assembled at KnAAPO in Komsomolsk-on-Amur. So while the design team has been and probably still is busy, production facilities are seperate.That is the real scale Su-75 aircraft model they built for testing cockpit integration etc. The one showed at exhibitions. But according to the patents they changed the airframe design since.
Sukhoi should be real busy. With the Su-57M, Su-75, dual seater Su-57, S-70 drone.
There is a revised design, which is a refined version of the initial design shown by the mock up. With more internal space, presumably for fuel to increase range, also changes to some control surfaces etc.Is there a production Su-75 already?
but I think its just an unrelease photo back when Rostec did a photoshoot with a Su-57
