in recent years, I am carefully watching chinese engines;What engine is that? WS-10?
clearly ALL operational J16 & J20 are equipped with powerful chinese engines
currently china is switching more powerful chinese engine for J16 & J20
also, china is recently deploying J10C and J15 with powerful chinese engines
it NO longer uses old russian engine; it has better and more powerful engines
clearly NOT; and even technically impossible; AL31FN is too low thrust to maneuver such 20-ton heavyweight fighter; agile J20 CAN'T go with the old russian engineNo, clearly an AL-31FN
