Uh source?

JF-17 is a multirole attack aircraft, F-16 is a multiple air superiority fighter.

PAF has been very adamant that nothing they have tried compares to the F-16 in performance. Their last air skirmish was an F-16 that shot down an IAF MiG-21 in 2019. Even the J-10s they recently bought are still considered inferior.

The real joke here is expecting an F-16 to actually reach Ukraine lmao. Pakistan had to basically play double agent to convince the USA to even open F-16 sales. There's a 0% chance they're going to give Ukraine F-16s for free, or even let them be leased from other countries.
