The United States (US) has officially approved a significant sale of advanced technology and support for Pakistan’s F-16 fighter jets. Valued at $686 million, the deal aims to modernise the fleet and address critical safety concerns. The US Defence Security Cooperation Agency (DSCA) confirmed the details in a letter sent to Congress on December 8.
Lockheed Martin, based in Fort Worth, Texas, will serve as the principal contractor for this extensive project.
Inside the $686 Million Package
The total sale is separated into $37 million for Major Defence Equipment (MDE) and $649 million for other essential items.
The standout component involves 92 Link–16 data link systems. This advanced command and control network allows for real-time, secure communication between US and NATO forces. Furthermore, it is highly resistant to electronic jamming from enemy assets.
Beyond the Link-16 systems, the package includes:
- Cryptographic Equipment: This features KY–58M and KIV–78 cryptographic appliqués and AN/APQ–10C Simple Key Loaders.
- Avionics Updates: Comprehensive hardware and software modifications to support the Operational Flight Program.
- Testing Gear: Six inert Mk–82 500-lb general-purpose bomb bodies for weapons integration testing.
- Identification Systems: AN/APX–126 Advanced Identification Friend or Foe systems to distinguish between hostile and allied aircraft.
Additionally, the deal covers full-motion simulators, spare parts, and personnel training.
The US Strategic Rationale & Regional Impact
The DSCA letter clearly outlines the motivation behind this approval. Primarily, the sale supports US foreign policy and national security objectives. It ensures Pakistan retains interoperability with the US and partner forces during ongoing counterterrorism efforts.
Moreover, the upgrade extends the operational life of Pakistan’s F-16 fleet through 2040. The updates specifically target the Block–52 and Mid-Life Upgrade (MLU) aircraft. The DSCA emphasised that this refurbishment addresses critical flight safety concerns while enabling seamless integration between the Pakistan Air Force and the US Air Force.
Crucially, the agency asserted that this equipment will not alter the basic military balance in the region.
A Long-Awaited Upgrade
Pakistan originally requested these upgrades in 2021. However, diplomatic strains delayed Washington’s response.
Since then, the landscape has shifted. Pakistan is now less dependent on the F-16 platform, having acquired and developed other assets. These alternative platforms proved their value during the May 2025 air war, where they inflicted significant damage on the Indian fleet.
Despite this diversification, Pakistan welcomes the US offer. A diplomatic source noted that the deal enhances the “shelf life” of the F-16s significantly. The implementation of this sale will not require additional US Government or contractor representatives on the ground in Pakistan.
