@Oscar @messiach I might be misreading the situation, but is the PAF basically shifting development resources now to the 5th-gen fighter (FGF)? There's no mention of a JF-17 variant after the Block-III, and the PAF basically dismissed any thought of enlarging the JF-17 airframe. Are they now preparing to move away from the Thunder (at least in terms of development) and expediting to the FGF?
Interestingly, early in 2017 Mikoyan had floated the idea of a lightweight single engine 5th-gen fighter using a new version of the RD-33 turbofan engine.
