US EditionRussia's Stealthy Skies: The Su-57 Fighter's Engine Upgrade
The Su-57’s new AL-51F engines offer increased thrust and fuel efficiency, marking a key advancement after 15 years of development, Rostec said.
- On December 22, reports said a production-series Sukhoi Su-57 fighter completed its first flight powered by two izdeliye 177 engines mounted in its two nacelles.
- Long-Standing delays meant the T-50 prototype first flew in 2010 using interim AL-41F-1 engines while Ufa Engine Production Association developed the izdeliye 30, first flown on December 5, 2017, with deliveries projected for 2023.
- The new engine should, according to designers, produce 17–18 tons of thrust with better fuel efficiency, enabling supercruise and meeting original speed and range specifications.
- Foreign customers' interest is high and export deliveries are underway, while Sukhoi is modernizing the Su-57 using Special Military Operation zone experience to expand weapons and systems.
- The step narrows gaps but highlights Russia's propulsion lag as the United States and China push ahead with sixth-generation designs, while izdeliye 177's performance remains below forecasts.
