Ovo je najveća razlika. F-35 je dizajniran od nule sa stealthom kao primarnom karakteristikom. Njegov radarski presek (RCS) se procenjuje na (veličina metalne loptice za golf). Su-57, sa druge strane, ima RCS od 0.1–1.0 m² (veličine veće ptice ili malog televizora).
Russia built the Su-57 to be an "air dominance" heavyweight. It is designed for high-speed, aggressive maneuvering. With 3D thrust vectoring , it can pull off extreme "nose-high" maneuvers that defy standard aerodynamics. su 57 protiv f 35
The Su-57, on the other hand, offers a more traditional approach to air combat, with a focus on maneuverability and payload capacity. While it is a capable aircraft, it may not be as effective in a modern battlefield, where stealth and network-centric warfare are becoming increasingly important. Ovo je najveća razlika
