Russia has unveiled a potential stealth enhancement for the Su-57 fighter jet, focusing on advanced engine nozzle modifications aimed at reducing radar detection. The demonstration took place on an export model, the Su-57E, displayed at the Dubai Airshow 2025, highlighting ongoing efforts to modernize the aircraft’s propulsion system for international buyers.
The original Su-57, introduced in 2010 and featuring axi-symmetric nozzles behind its AL-41F engines, entered service in 2020. Recent developments include a telescoping nozzle design with side panels, which could significantly improve the aircraft’s radar profile. This upgrade signals Russia's strategic intent to enhance its export offerings amidst a competitive defense market.
The display, organized by United Aircraft Corporation, indicates that such stealth nozzle technology is being offered to potential customers, including Algeria. Experts suggest that these updates could make the Su-57 more attractive to nations seeking advanced, stealthy fighter aircraft, potentially impacting regional defense dynamics.
Military aviation analyst Steve Trimble noted that these developments reflect Russia's broader strategy to maintain and expand its export influence through technological upgrades. The Su-57E's new nozzles exemplify Russia’s commitment to providing modern, competitive fighter aircraft to the international market, bolstering its position in the global arms industry.
