The United States has approved a major defence upgrade for Pakistan. The US Defence Security Cooperation Agency (DSCA) notified Congress of a $686 million package. This funding will modernise the Pakistan Air Force’s (PAF) F-16 fighter jet fleet.
The DSCA’s official letter triggered a mandatory 30-day congressional review. US lawmakers will now debate the proposed upgrade during this period. The agency stated the sale supports US foreign policy and national security objectives. It aims to maintain Pakistan’s interoperability with US forces.
This interoperability is crucial for ongoing counterterrorism cooperation. It also prepares for potential future contingency operations. The upgrade package includes several key advanced systems. Among them are secure Link-16 tactical data-link networks and modern cryptographic equipment.

Link-16 is a secure, encrypted network used by NATO and partners. It enables aircraft, ships, and ground units to share real-time battlefield information securely.
The DSCA letter detailed the upgrade’s specific benefits. It will modernise Pakistan’s Block-52 and Mid-Life Upgrade (MLU) F-16 aircraft. These updates enable more seamless integration with the US Air Force during joint exercises and operations.
The refurbishment will extend the operational service life of these jets through 2040. It will also address critical flight safety concerns identified in the ageing fleet. The agency expressed confidence in Pakistan’s ability to absorb this technology.
