Washington/Islamabad– The United States has formally notified Congress on December 8 of a $686 million foreign military sale to upgrade and sustain the Pakistan Air Force’s F-16 fleet, triggering the mandatory 30-day Congressional review period.
The Defense Security Cooperation Agency (DSCA) stated that the package includes advanced Link-16 data-link systems, secure cryptographic equipment, avionics upgrades, pilot training, spare parts, and long-term logistical support. The upgrades will extend the operational life of Pakistan’s Block-52 and Mid-Life Update F-16s through 2040 while addressing critical flight-safety issues.
“This proposed sale will support the foreign policy and national security objectives of the United States by allowing Pakistan to retain interoperability with U.S. and partner forces in ongoing counterterrorism efforts,” the DSCA letter read. It added that the enhancements would enable “more seamless integration” between the Pakistan Air Force and U.S. Air Force during combat operations, exercises, and training.
The decision comes amid a year after the Trump administration unfroze $397 million in Foreign Military Financing for Pakistan’s F-16 sustainment programme in February 2025, with the explicit condition that the jets be used only for counterterrorism and not against India.
Relations between Washington and Islamabad have visibly warmed since President Donald Trump’s recent meetings with Prime Minister Shehbaz Sharif and Chief of Defence Forces Field Marshal Syed Asim Munir.
The notification revives memories of the 2019 Balakot crisis when Pakistan was accused of using U.S.-supplied F-16s in an aerial engagement with India, prompting temporary suspension of security assistance. U.S. officials say the new package includes stricter end-use monitoring provisions.
Congress now has until early January 2026 to block or modify the sale, though no formal objections have been announced yet.
