Russia’s fifth-generation stealth fighter, the Su-57, has successfully completed its maiden flight powered by the new Izdeliye 177 engine, marking a significant milestone in the aircraft’s development. This advanced engine, which promises increased thrust and improved flight performance, has transitioned from ground testing to actual flight, addressing previous concerns about its operational readiness. The Su-57, claimed by Russia to be the only combat-proven fifth-generation fighter, is positioned to attract international customers, particularly the Indian Air Force, which prioritizes engine performance and upgrade potential. As Moscow intensifies its export efforts, it remains to be seen whether the 177 engine will be part of the standard export package or contingent upon deeper industrial collaboration with India, potentially influencing future co-development agreements. The growing advancements in the Su-57 program highlight Russia’s ambition to remain competitive in the global defense market while offering India a pathway towards enhanced indigenous capabilities.
