At Aero India 2025, held at Air Force Station Yelahanka in Bengaluru, Russia has unveiled a groundbreaking proposal to India, marking a significant milestone in their bilateral cooperation.

Rosoboronexport and United Aircraft Corporation (UAC) have offered India the opportunity to locally manufacture the Su-57E, the export variant of Russia’s fifth-generation stealth fighter jet. This offer includes a comprehensive Transfer of Technology (ToT), which would allow India to integrate its own systems and subsystems into the Su-57E.

With this move, Russia is not only supporting India’s defense modernization but also its ‘Make in India’ initiative.

This offers India a unique opportunity to not only acquire advanced technology but also develop its own systems that can be used across its fleet, including the AMCA (Advanced Medium Combat Aircraft) program. The ToT is designed to enhance India’s self-reliance in defense technology, helping the country achieve its long-term goal of becoming a defense technology powerhouse.

The Su-57E is a versatile stealth fighter designed for air, ground, and naval strike missions. It features advanced avionics resistant to electronic warfare, supercruise capability for sustained supersonic flight, and high maneuverability. With 12 hardpoints, including 6 internal bays, it carries a maximum payload of 7,500 kg.

The aircraft has a combat range of 7,800 km with in-flight refueling and can reach speeds of up to 1,350 km/h. Its powerful engines provide 14,500 kgf thrust each, allowing it to operate 24/7 in high-intensity environments.

Engine Options and Future Prospects

A critical component of any fighter jet is its engine, and the Su-57E comes equipped with the AL-41F-1S engine, a highly capable turbofan designed to meet the demands of modern aerial warfare. This engine provides 9 tonnes of dry thrust and 14.5 tonnes with afterburner, enabling the Su-57E to achieve supersonic speeds while maintaining excellent maneuverability.

However, Russia has also hinted at the potential for a future upgrade to the AL-51 engine (also known as the Izdeliye 30). This next-generation engine offers supercruise capabilities, allowing sustained supersonic flight without afterburners. With a thrust rating of 11 tonnes dry and 17.5 tonnes with afterburner, the AL-51 engine would significantly enhance the Su-57E’s performance, providing a future-proof upgrade as India’s defense needs evolve.

Russia’s Role in Supporting India’s AMCA Program

In addition to offering the Su-57E, Russia has expressed its willingness to assist India in the development of its Advanced Medium Combat Aircraft (AMCA). As India faces delays in the AMCA program, partly due to engine procurement issues and technological challenges, Russia’s expertise in areas like stealth technology, advanced avionics, and weapons integration could help accelerate the program’s development.

This collaboration is expected to shorten the timeline for India’s indigenous fifth-generation fighter and align it with India’s long-term defense goals.
