Introduction
The current Su-57 is just the foundation. Russia’s Su-57M AI upgrade roadmap takes the Felon into 5.5-generation territory, where artificial intelligence does far more than assist a human pilot.
Slated for late 2026, the Su-57M variant will feature deeply integrated AI across all systems. A follow-on M2 version will push even closer to an autonomous operational framework. These upgrades are not speculative concepts; they are funded programs with confirmed timelines.
This post walks through the Su-57M AI upgrade roadmap step by step. You will see what changes with the M variant. You will learn about the new engine and enhanced stealth features. And you will understand how the M2 pushes autonomy further than any Russian fighter before it.
For the big picture on the current AI systems, see our pillar post on Su-57 fighter artificial intelligence . For details on the electronic co-pilot being upgraded, read our Su-57 AI co-pilot system guide .
The Su-57M: What Arrives in Late 2026
The first milestone on the Su-57M AI upgrade roadmap targets late 2026. This variant is not a clean-sheet design but a significant evolution of the existing airframe.
The most important change is deeper AI integration. The electronic co-pilot gains improved threat recognition algorithms and faster processing hardware. The sensor fusion engine will correlate data from more sources, including offboard sensors on drones and ground radars. Decision support becomes more automated, though the human pilot retains final authority.
Stealth characteristics also improve. The Su-57M incorporates revised surface coatings and treated engine inlets that reduce radar returns from the front and sides. These modifications address one of the long-standing criticisms of the baseline Su-57.
The cockpit receives a new helmet-mounted targeting system. This allows the pilot to cue weapons simply by looking at a target. The AI processes head position data alongside radar and infrared sensor inputs to prioritize threats in the pilot’s field of view.
The AL-51F-1 Engine: Power and Thermal Management
A critical component of the Su-57M AI upgrade roadmap is the new AL-51F-1 engine, expected around 2030.
The current AL-41F1 is a capable powerplant but generates significant heat that limits the aircraft’s infrared stealth. The AL-51F-1 addresses this with advanced thermal management, reducing the Su-57M’s heat signature. This matters because infrared sensors on modern fighters and air defense systems can detect hot engine exhaust at considerable ranges.
The new engine also provides more electrical power for the upgraded AI processing hardware and electronic warfare suites. More power means more capable systems without sacrificing range or payload.
The Su-57M2: Toward Autonomous Mission Planning
The Su-57M AI upgrade roadmap does not stop at the M variant. The proposed Su-57M2 pushes further into autonomous operations.
The defining feature is intelligent mission planning. The AI will optimize entire sorties, not just individual engagements. It will consider fuel consumption, threat locations, target priorities, and weather conditions. The system will generate a complete mission plan that the human pilot reviews and approves.
This shifts the pilot’s role further from operator to supervisor. The AI handles the tactical complexity. The human focuses on strategic decisions and ethical judgments that machines cannot make. If the Su-57M2 reaches production, Russia will field a fighter with a level of autonomy unmatched by any current Western aircraft.

What This Means for Export Customers
The Su-57M AI upgrade roadmap also has significant implications for export customers like India.
Russia has indicated that the M1E export variant will mirror many of the M’s upgrades, including the AI enhancements. If India proceeds with the Su-57E co-production deal, access to the continuously improving AI source code becomes a major long-term benefit. India would not just buy a static fighter; it would buy into an evolving platform.

Conclusion
The Su-57M AI upgrade roadmap reveals Russia’s long game. The current Su-57 is a capable fifth-generation fighter. The upcoming M variant pushes it to 5.5-generation status with deeper AI, improved stealth, and a new engine. The M2 concept challenges the very definition of a manned fighter.
Russia is betting that intelligent automation, more than raw speed or payload, will define the next era of air combat. The roadmap proves this bet is backed by concrete engineering, not just marketing brochures.
