The Russian replacement Su-57 fighter will have a flat nozzle.

Despite the fact that relatively recently, American F-22 fighters criticized for the presence of a flat nozzle, noting that in this case there is no question of complete control of the engine's thrust, Russian aircraft designers, for unknown reasons, decided to install such a nozzle on a heavy impact drone C-70 "Hunter", considered a replacement for the Russian Su-57.

“The same product that is represented in the model, at least that conceptual look reflected in it, is, of course, the development of the theme of the current prototype demonstrator, only in a form suitable for serial production and for operation according to the tasks of the Ministry of Defense "- the representative of Sukhoi reports in an interview with Zvezda.

For what reason it was decided to install a flat nozzle on a heavy impact unmanned aerial vehicle, and how it will improve the capabilities of a combat drone is unknown, however, experts note that in future, a flat nozzle will seriously affect the maneuverability of an unmanned aerial vehicle and an unmanned fighter the sixth generation, created on the basis of this model.
