In short, The Defense Ministry of Argentina has requested to include USD 664 million for the 2022 Budget for the acquisition of multipurpose fighter aircraft, but the budget has not been issued regarding the purchase of supersonic aircraft of any origin.
Conclusion: The claim that Argentina is buying JF-17 fighters from Pakistan is fake and misleading.
