I have no idea if it's true but don't know what the fuss it's about, and have no problem believing it either.
Even F22 get beaten in dogfights by non-stealth jets sometimes. Others with generational gaps like F15/16 getting beaten by F5/A4/Mig21 etc in WVR is not uncommon as well.
And with exercises, rules of engagements are often less than 100% real life anyway.
PAF pilots are after all among the best dog-fighters there are. I'd even put them above USAF. I don't think they'll compare too badly against the Israelis either.
I completely disagree.. Mirage III got lock more times in BVR by J-10 and shot down more is acceptable.
But a 60's Mirage III vintage that is famous for lack of turns and agility shot down more of J-10 in WVR is laughable.
We are not talking about J-7PG. J-7PG despite carry the Mig-21 legacy has modify crank wing that helps in low speed turn and much powerful engine which still makes it fearsome in dogfight.
The Mirage III uses by PAF is essential now has no physically different of any help in agility from the 60s design .
