More strawmans and sidetracking lmao, you really are a Chinese bot
No one denies that the J-10C/E uses the WS-10B engine. We all know it does. It's literally the reason we are having this discussion.
No one is discussing the leap or the greater capabilities the J-10 provides to the PAF. We are talking about Chinese engine quality in relation to western counterparts.
Does the CCP training program include strawman and sidetracking once logical responses are not possible?
Let me repeat:
You have no evidence to prove that Chinese engines are at the same level as western counterparts. The only thing we can confidently assume is that they are reliable and sufficient enough to be used across multiple platforms in large numbers across the PLAAF.
Knowing Pakistan's desperate position to upgrade it's capabilities but also having restrictions in accessing western aircraft and also funding due to a declining economy, it's entirely possible that J-10 was only offered with Chinese engines without the possibility of Russian alternatives, so they went with it.
