The improvements to the advanced Su-57 have been described in detail in military aircraft diagrams before, but the brief summary is that it is a change of aircraft" Products - 30" turbofan engine, replacement of hydraulic actuator with electro-hydrostatic actuator, new display, expansion of airborne weaponry systems these four major improvement items. At present, the technical appearance of the advanced Su-57 fighter has been determined, with the exception of the engine profile, the basic aerodynamics of the advanced Su-57. The shape will be identical to the current Su-57.
There is another interesting detail about the advanced Su-57. The advanced Su-57 is officially called "Su-57 Stage 2", while the Russian military and manufacturers have given it the official nickname "Su-57". Super Sukhoi" (Супер-Сухим). There is no official nickname for the Su-57, but NATO gave it the nickname "Felon", which is the name of the "Super Sukhoi". A malicious nickname, compared to the Russian Defense Ministry's "Super Sukhoi" sounds much more normal.

The nickname "Super Sukhoi" is interesting, as it may indicate the Su-27 "Flanker" family, of which the Sukhoi Design Bureau is proud. It's about to officially end after the Su-57 generation. Although the Su-57 is classified as a fifth-generation fighter, the aircraft's aerodynamic layout and design philosophy is still inextricably linked to that of the Su-27. Many people are accustomed to treating the Su-57 as a flattened version of the Su-27, which is not entirely unjustified. If the Su-35 is the "top of the flank", then the Su-57 can indeed be called the "Super Sukhoi". The Sukhoi Design Bureau's next fighter will be an all-new series, after which the flanker series should be finished anyway.
It is planned that the Super Sukhoi will go into production in 2024, and until then the Russian Aerospace Manufacturing Group will supply the Russian Air Force with a limited number of Su-57s in a low production mode.
