WS-10C2 and it's successor engine is for J-20. Current production of J-20 is using it. WS-10C2 has incorporated the technologies of WS-15 in its new batches. WS-10C2 and it's New batches can be retrofitted into earlier 350 J-20 aircrafts by removing their inlet heat exchangers. It would give them enhanced range and speed.
Currently J-20A with WS-15 is going through testing and evaluation. It seems further fuselage redesign is sought to increase the weopens load, speed and range of J-20A. During that time production of WS-15 would be ramped up for J-20A. China is thoroughly testing the J-20A and WS-15. It always takes time. We would see the J-20A in Q2 2026, LRIP in Q3-4 2026 and production in 2027. China doesn't need to rush in unnecessarily. Redesign would take time to test and evaluate.
J-20A/S would see the light steadily. No short cuts would be sought. Every step would be evaluated and validated leading to production of the systems in J-20A/S including WS-15 engines, avionics and sensors.
