As we reported before, a new batch of J-10B fighters have joined Chinese air force, and according to latest photos shot by military fans, some new J-10B fighters are using homemade WS-10 engine (Taihang), instead of Russian AL-31FN, which is not stable for single-engine J-10 series.
So China Military is still making great efforts to develop homemade engines for J-10 jet fighters, and AL-31FN engine from Russia is only regarded as an alternative solution in the long run. Below are more photos of Chinese J-10B fighters with homemade WS-10 engine.
