Per Sukhoi itself claiming this.
Did you know the Su-57 Felon has the same RCS of a clean F/A-18 Super Hornet (and 1,000 times bigger than that of the F-35)?
The configuration of the
Sukhoi Su-57 Felon is an evolution of the Su-27’s shape adapted for the requirements of low visibility and
supersonic speed and agility.
According to Sukhoi, the Su-57’s
radar cross section (RCS) is reduced to an average figure of 0.3-0.4m2 compared to 15m2 for
the Su-27. As explained by
Piotr Butowski in his book
Russia’s Warplanes, Volume 1, the main solution to reduce radar visibility is internal carriage of weapons. Radar blockers reduce reflections from the engine inlet guide vanes and are installed in the engine air intake ducts. The shape of the airframe has been selected to reduce the number of directions in which electro-magnetic waves are reflected, and to ensure these directions are the safest.
