A Russian source collected by Military Watch Magazine (MWM) shows that the Komsomolsk-on-Amur aircraft manufacturing plant is planning to put upgraded versions of the Su-57 fighter jet into production, with the designation Su-57M1.
According to information revealed by the United States Aircraft Corporation (UAC), the Su-57M1 will have a number of changes to improve performance, notably the extended fuselage to increase aerodynamic lift and improve stability when flying at hypersonic speeds. This design allows the Su-57M1 to maintain hypersonic flight capability without the need for an auxiliary incinerator.
Improvements to the chassis are also aimed at maximizing the outstanding flight performance that the new AL-51F engine brings. AL-51F is the first completely newly designed fighter engine that Russia has put into use in more than 40 years.
The Su-57M1 version will have a flatter fuselage and an internal weapons cabin to increase visibility. The aircraft will also be equipped with new radar, which will help reduce radar reflection and increase survival on modern battlefields.
Previously, the Su-57 was the only Russian fighter to use active phage radar (AESA) in the flap. The transition to a new generation of radar promises to significantly improve the ability to recognize and control situations.
In addition to the design and sensors, the Su-57's aviation electronic system has also been modernized. The manufacturer integrates artificial intelligence (AI) into the control system, allowing quick start with just one button - simplifying the pre-flight inspection process and increasing combat readiness.
The Su-57M1 is expected to carry a series of new weapons and systems, including a completed and mass-produced version of the long-range anti-aircraft missile R-77M - a type of weapon that aims to narrow the effective range with the US AIM-260 and China's PL 15.
In addition, Russia introduced a new generation pilot helmet wearing target sightseeing system in December 2024. The device projects flight information and target data directly onto the helmet, similar to the technology used on the US F-35 and China's J20.
With the Su-57 - also known as the "Cobra Maneuver" - long identified as Russia's most powerful tactical fighter, capable of destroying many types of targets thanks to its high-precision weapons system, the Su-57M1 promises to open up remarkable steps in both technology and combat performance.
