Generally in U.S foreign arms sale government-to-government agreements, the United States requires the receiving country to allow American officials to inspect the equipment regularly to ensure that the inventory of arms is accounted for and protected.
One of the senior U.S. defense officials with direct knowledge of the count said that Pakistan invited the United States to physically count its F-16 planes after the incident as part of the agreement. Although most of Pakistan’s F-16s are from USA, some are sourced from Jordan.
“If you are a user of American defense products, you need to go through a very clear process to send those weapons to a third party,” explained said Richard Aboulafia, an analyst with the Teal Group, an aerospace and defense firm. The United States has a rigid process in place to try to ensure its equipment does not fall into the hands of “hostile actors.”
Air Vice Marshal RGK Kapoor in a press conference showed slides of radar blips of the allegedly downed F-16 Falcon disappear. Also, multiple sources including various Pakistan officials corroborated that there were two ejections during the dogfight, one was Wing Commander Abhinandan who was apprehended across the LoC in PoK, the second has to be an unidentified PAF pilot who was immediately hospitalized.
The Pakistan government seems to be keeping quiet about the loss as they have always tried to uphold an invincible image to overcompensate for their defeat in all the wars between the neighbors.
Although US officials have stated that there were no clauses in the agreement of Foreign Military Sales for the F-16 Falcon that said the PAF couldn’t use the fighters in combat, Pakistan’s denial that it never used F-16 in the attack and the irrefutable evidence provided by the IAF refuting it will greatly maim its credibility.
