I still don't believe u can make a 180 kn engine with meaningful t/w
Russians made al-41 20 years back but had lot of weight.
p and w f-135 has 190-200 kn and it was made only few years back so china cannot take such a leap so fast.
It will take 10 years imho.
140 KN is possible as u had al-31 and f-100 as template while 155-180 kn would be new designs and hence require extensive testing
Right now the basic model of WS-10 is 135kN, so 155kN is just an improvement.
While the 180kN WS-15 will be completely new successor generation of the WS-10 engine.
The AL-31F is 125kN, so 117 has 145kN. And don't get me wrong, 117 is not completely a new generation, but a AL-31F on steroid.
Right now, the only rival of the F119 will be the S-15, not anything else.
