The J35 project, according to the AI result, is moving along well.

However, there are other results on WS 19. Like us, getting a working engine is a problem.

The WS-19 engine for China's J-35 fighter is in testing, with first public reports suggesting it's designed to provide significantly more thrust than the WS-13 and WS-21 engines on earlier J-35 prototypes, but it may not be in widespread production for operational service yet. While the J-35 aircraft itself has entered service, the WS-19 engine is expected to be the definitive, more powerful engine for the aircraft but is still undergoing testing and integration.
WS-19 Engine Status
Under Development & Testing: The WS-19 is a key, advanced engine intended for the J-35, but it is still undergoing testing to meet its full performance and reliability requirements.
Improved Thrust: It is expected to offer a significant increase in thrust compared to the interim WS-13 and WS-21 engines used on earlier J-35 prototypes.
Critical for Operational Readiness: The engine's development is critical for the J-35 to achieve its full potential and for the aircraft to be considered truly combat-ready.
J-35 and Engine Relationship
Early Prototypes: Early J-35 prototypes were fitted with less powerful engines like the WS-13 and WS-21, which were not adequate for the heavier, redesigned airframe.
Planned for Deployment: The J-35, powered by the more advanced WS-19 engine, is intended to be a crucial component of China's growing aircraft carrier fleet.
Future of the Aircraft: The full operational capability and performance of the J-35 will depend on the successful development and integration of the WS-19 engine.
