I would love to be wrong, if JF-17 gets WS-13E. That would mean a lot of things, foremost being that WS-13E is mature & a good bit of improvement over RD-93. JF-17 needs all the dry thrust it can get to ensure that avionics have ample power to operate to their limits. More options can only be good for the program.Why? I would actually love for you to be right. Previous post was MY guess work. And my reasoning for it was that PAF has never given any official indication about wanting the RD-93 MA or any other engine, and have infact always said they are satisfied with the existing engine. And of course I could be wrong about finances being the reason and I hope I am.
Obviously neither of us knows the real reason, only PAF knows the real reason.
