Before comparing thrust-to-weight ratios or radar cross-sections (RCS), one must understand what each nation asked the jet to do.
Bottom Line: The F-35 wants to kill you before you know it exists. The Su-57 wants to kill you in a chaotic, close-in brawl if stealth fails.
| Domain | Winner | | :--- | :--- | | Stealth | F-35 (overwhelming) | | Avionics/Sensors | F-35 | | BVR Engagement | F-35 (80%+) | | WVR Dogfight | Su-57 | | Speed/Altitude | Su-57 | | Production/Sustainment | F-35 (by orders of magnitude) | | Cost | F-35 ($80M–110M) vs. Su-57 (~$35–40M internally, but real cost higher) |
Final Judgment: The Su-57 is a failed fifth-generation fighter—it sacrifices stealth for maneuverability at a time when BVR missiles have made dogfighting a secondary skill. The F-35 is a revolutionary battlespace manager that happens to carry weapons.
In a 1v1, the F-35 will win 7 times out of 10 by staying invisible and shooting from range.
In a real war, 200 F-35s will destroy every Su-57 on the ground, then bomb the factory that builds them.
The Su-57 is dangerous—but only if the F-35 makes the mistake of turning it into a knife fight. And no F-35 pilot will ever give it that chance.
The debate of Su-57 protiv F-35 is more than just a comparison of two fighter jets; it is a clash of two fundamentally different military philosophies. While both are categorized as fifth-generation aircraft, their designs reflect the distinct priorities of Russian and American air power: the Su-57 "Felon" is a heavyweight air superiority fighter built for speed and agility, while the F-35 "Lightning II" is a multirole "system of systems" optimized for stealth and networked warfare. Design Philosophy and Stealth
The most significant divide between these two aircraft lies in their approach to stealth (low observability).
F-35 Lightning II: Designed from the ground up to be nearly invisible to radar. It features an "all-aspect" stealth design, meaning it is difficult to detect from any angle. Its radar cross-section (RCS) is estimated at roughly 0.005 m², making it approximately the size of a metal marble on radar screens.
Su-57 Felon: Russian designers prioritized supermaneuverability and speed over absolute stealth. While it incorporates radar-absorbing materials and a faceted airframe, its RCS is estimated to be significantly larger, between 0.1 and 0.5 m². Russia's doctrine suggests that stealth is only one tool, and it can be countered by the Su-57’s unique L-band wing-mounted radars designed to detect stealthy targets. Flight Performance and Maneuverability
If a battle moves from long-range missiles to a close-quarters dogfight, the advantage shifts toward the Russian platform.
Kinematics: The Su-57 is a twin-engine beast capable of Mach 2.0 and can "supercruise" (fly supersonic without afterburners) at Mach 1.3. It features 3D thrust-vectoring nozzles, allowing it to perform extreme maneuvers that would stall other aircraft.
The F-35's Role: The F-35 is a single-engine aircraft with a top speed of Mach 1.6 and limited supersonic dash capabilities. It is not designed to win a traditional dogfight through acrobatics; instead, its goal is to "see first, shoot first" from a distance and vanish before the enemy knows it was there. Sensors, Avionics, and Networking
The modern battlefield is won by information, and this is where the Lockheed Martin F-35 excels.
Sensor Fusion: The F-35’s greatest strength is its ability to gather data from various sensors and "fuse" it into a single, easy-to-read picture for the pilot. It acts as a central hub, sharing data with other jets, ships, and ground forces in real-time.
Su-57 Radar: The Su-57 carries the N036 Byelka radar system, which provides a wider field of view (270 degrees) compared to the F-35’s forward-facing radar cone. While it has impressive raw hardware, it reportedly lags in the automated data integration that makes the F-35 so lethal in complex environments. Weapons and Payload

The story of the Su-57 Felon versus the F-35 Lightning II is essentially a tale of two different visions for modern air warfare: one that prioritizes brute force and agility (Russia) and another that bets entirely on stealth and data (USA). 1. The Design Philosophies
Sukhoi Su-57 (The Agile Hunter): 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.
F-35 Lightning II (The Invisible Quarterback): The F-35 is a multi-role strike fighter that prioritizes low observability (stealth) and sensor fusion. Its goal isn't to out-turn the enemy in a dogfight; it’s to detect them from hundreds of miles away and destroy them before the enemy even knows they are being tracked. 2.

F-35 vs Su-57 Comparison | Which is the BEST Stealth Fighter?
A comparison between the Sukhoi Su-57 "Felon" and the Lockheed Martin F-35 "Lightning II" reveals a clash of two distinct military philosophies: raw kinematic power versus high-tech stealth and data fusion.
As of early 2026, the F-35 maintains a massive lead in global deployment, with over 1,300 units in service across more than 20 nations, compared to roughly 30–32 operational Su-57s in the Russian Aerospace Forces. Su-57 vs. F-35: Technical Breakdown Su-57 "Felon" F-35 "Lightning II" Max Speed Mach 2.0+ (Supercruise at Mach 1.3) Combat Radius ~1,500 km (Ferry range ~5,000 km) ~1,100 km (Ferry range ~2,220 km) Stealth (RCS) Estimated 0.1 to 1.0 m² Estimated 0.001 to 0.005 m² Maneuverability Supermaneuverable (3D thrust vectoring) High agility (no thrust vectoring) Primary Focus Air superiority & high-speed interception Networked warfare & stealth strike Key Performance Differences
Russia’s Su-57 Felon vs. America’s F-35 Lightning II: Who Would Win?
Here’s a concise, balanced draft write-up for a comparison titled “Su-57 Protiv F-35” (Su-57 vs. F-35). It’s written in an analytical, defense-journalism style suitable for a blog, video script, or short article.
The F-35 wins before takeoff.
Even if the Su-57 were technically superior in a 1v1 (it isn’t overall), Russia cannot afford to lose them. The F-35 is a consumable weapon system in US doctrine.
