Pakistan has welcomed the US approval of advanced technology and support for its F-16 fighter jets, a $686 million package aimed at upgrading the aircraft and extending their operational life until 2040.

The announcement was confirmed by a letter from the US Defense Security Cooperation Agency (DSCA) to Congress on December 8, 2025.

Details of F-16 upgrade

The US sale package includes:

Link-16 data systems for secure communications
Cryptographic equipment and avionics upgrades
Training, simulators, spare parts, and full logistical support

The upgrade will modernize Pakistan’s Block-52 and Mid-Life Upgrade F-16 aircraft, ensuring they remain operational and effective in current and future scenarios.

Strategic importance

According to the DSCA, the sale aligns with US foreign and national security objectives, helping Pakistan maintain interoperability with the US and its allies in counter-terrorism operations.

A Foreign Office spokesperson welcomed the decision, stating that the package will strengthen Pakistan’s defense capabilities, improve the security of its fleet, and enable safe and effective operation of the aircraft.

Financial and technical details

Total package value: $686 million
Major defense equipment: $37 million (92 Link-16 systems and six unexploded Mk-82 bomb bodies)
Other equipment and support: $649 million (identification systems, cryptographic modules, software and hardware upgrades, training, simulators, and technical support)

Lockheed Martin will serve as the prime contractor, and no additional US personnel will be deployed in Pakistan for the implementation.

Pakistan first applied for the F-16 upgrade in 2021, but the process was delayed. While Pakistan is increasingly relying on other fighter platforms, this upgrade is welcomed as it extends the operational life of the F-16 fleet to 2040 and ensures continued readiness in regional security operations.
