The United States has approved a $686 million Foreign Military Sales (FMS) package to modernize Pakistan’s F-16 fighter jet fleet. The Defense Security Cooperation Agency (DSCA) formally notified Congress after the proposal cleared the 30-day review period without objections. Lockheed Martin will serve as the primary contractor, providing hardware and software upgrades, maintenance, and technical support.

According to DSCA, the package includes 92 Link-16 data-link systems, avionics modernization, secure communication tools, and training equipment. Of the total cost, $37 million will cover major defense items, while $649 million will go toward maintenance and modernization services. The upgrades aim to extend the operational life of Pakistan’s Block-52 and Mid-Life Upgrade F-16 aircraft to 2040 and maintain interoperability with U.S. and allied forces.

Washington emphasized that the sale aligns with U.S. foreign policy and national security interests, supporting counterterrorism cooperation without altering the regional military balance. Pakistan first requested the upgrade in 2021–22, but the process only advanced under the Trump administration in late 2025 after previous delays.
