A Chinese J-20A stealth fighter equipped with the new indigenous WS-15 engines has reportedly completed its first test flight, marking a major milestone for China’s aerospace industry.
This development represents the culmination of decades of research aimed at overcoming the "Achilles' heel" of Chinese aviation—high-performance jet propulsion—by replacing the interim WS-10 and Russian-made engines. The WS-15 is designed to match or exceed the performance of the U.S. F-22’s F119 engine, providing the "Mighty Dragon" with superior thrust, enhanced supercruise capabilities, and the electrical power necessary for future advanced systems.
This successful integration, alongside other airframe refinements like a redesigned radome and cockpit, signals that the J-20 is reaching its "ultimate form" and cements China’s growing strategic autonomy in military technology.
