The Su-57 is marketed as stealth fighter but radars have between 6 to 10 times greater detection range against the Felon compared to F-22 & F-35. Here’s why.

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.
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.
Another group of stealth measures concern the fighter’s equipment. The surfaces of the NO36 radar arrays are deflected from the vertical plane, thus deflecting the enemy radar’s radiation aside. The domes of the arrays are selective — they let their own signal pass through and block other frequencies. In addition, the compartments for these arrays feature radar-absorbent coatings on their edges to absorb ‘freak waves’ (which occur when a wave is amplified after multiple reflections within an enclosed space). In order to reduce their total number, the available arrays are used by multiple systems…
