Is your source Haqeeqat TV??Just joking.From my source we can expect J-10 to fly in PAF before next March 23rd 2022 the deal is in the final legs. As per him it's capabilities are as good as F-16C.
We would have like 6 fighter's until Mirage and F 7 is retired.
I think this deal would be the same as VT 4 the crews would be in training right now in China and then in the end the planes would be revealed in an exercise or a parade.
