Taihang engine is already in-production and in-service with the PLAAF. Note the yellow serial numbers on the vertical stabilizer. These are in-service aircraft.
the Taihang's 14,000 kgf of maximum thrust is enough to surpass the AL-31F M1 (13,500 kgf) and AL-31FN Series 3 (13,700 kgf) and it slightly below the 117S (14,500 kgf), but very close.

The fact that the PLANAF is willing to use the Taihang should at least give you a clue regarding its reliability. Only a fool would fly an unreliable engine over water.
