US Approves $686 Million Tech Upgrade for Pakistan’s F-16 Fighter Jets

New Package Aims to Modernise and Extend Life of Aircraft

The United States has approved a $686 million technology upgrade package for Pakistan’s fleet of F-16 fighter jets. The approval was announced in a letter sent to the US Congress by the Defence Security Cooperation Agency (DSCA) on December 8, 2025.

The move will help Pakistan update its F-16 aircraft and keep them operational through 2040 with better communications and mission systems.

What the Upgrade Includes

The upgrade package will include:

• Link-16 tactical data link systems — secure digital communication used by US and allied forces.
• Advanced avionics and navigation equipment to improve jet performance.
• Encrypted communication and cryptographic gear for safe data exchange.
• Mission-planning hardware and software to help pilots prepare.
• Training, simulators, spare parts and long-term support for Pakistan’s air force.

About $37 million of the total goes toward defence equipment like Link-16 units and testing hardware. The rest pays for avionics, support services, parts, training and software.

Why the US Approved the Sale

According to the DSCA letter:

• The upgrades will help Pakistan modernise both Block-52 and Mid-Life Upgrade F-16s.
• The package is designed to extend the useful life of the jets through 2040.
• It will also help Pakistan’s Air Force operate more smoothly with the US and other partners during joint missions and training.
• The deal supports US foreign policy and security goals by strengthening the tools of a partner nation.

The DSCA also noted that the sale will not change the basic military balance in the region.

Who Will Carry Out the Work?

Lockheed Martin, the US defence company based in Fort Worth, Texas, is expected to be the main contractor for the upgrade programme. The work will include installation, testing, training and long-term support.

The US government has said no additional American military personnel will be posted in Pakistan as part of this arrangement.

What This Means for Pakistan’s Air Force

• The upgrades will help keep Pakistan’s F-16 jets relevant for years to come.
• Improved communication and navigation systems will make the aircraft more effective in modern operations.
• The extended service life gives Pakistan time to plan future aircraft purchases or development.

Regional Context

Pakistan has wanted F-16 upgrades for several years. The jets form a key part of its air force. Modernising them will help Pakistan keep pace with changing technology.

Neighbours and defence analysts will watch closely, as moves to upgrade fighter jets can affect regional defence dynamics. But US officials stress this package is meant to support Pakistan’s ongoing missions and maintain compatibility with allied systems.
