The United States has approved a modernization and support package worth approximately $686 million for Pakistan’s F-16 fighter jet fleet. The package includes advanced technology and equipment, training, logistics support, and secure communication and navigation systems. The objective is to upgrade Pakistan’s F-16 fleet to modern standards and keep it operational until around 2040. This decision further strengthens military cooperation between the United States and Pakistan, particularly within the broader South Asian security context. The approval was issued through a Congressional notification, and the implementation process is now underway.

India has expressed concern over the decision, as it is believed to potentially affect the regional balance of arms in South Asia. From Pakistan’s perspective, the package will enhance its military capability and security, especially by improving the safety, effectiveness, and interoperability of F-16 operations.

In recent developments, the U.S. Department of State has formally approved a Foreign Military Sales (FMS) package valued at nearly $686 million for the modernization and maintenance of the Pakistan Air Force’s F-16 fleet. Under this package, Mid-Life Upgrade (MLU) programs will be carried out on Pakistan’s existing F-16 Block-52 aircraft as well as earlier variants.

The upgrade program will be implemented by the American defense manufacturing company Lockheed Martin Corporation. Upon completion of the mid-life upgrade, Pakistan Air Force’s older F-16 fighter jets are expected to remain operationally effective until 2040.

One of the most significant elements of the package is the supply of 92 Link-16 data-link systems. Link-16 is a NATO-standard, secure, and jam-resistant tactical data-link system capable of exchanging real-time battlefield information among air, land, and naval units. In modern air combat, this technology plays a crucial role in enabling rapid decision-making.

Originally entering service in 1978, the U.S.-built F-16 Fighting Falcon has earned a reputation over the past four decades as one of the world’s most successful single-engine, multirole fighter aircraft. Its most advanced variant currently in service is the F-16V (Viper) Block 70/72, with an estimated international market price ranging between $100 million and $125 million per aircraft.

This single-engine fighter aircraft is powered by either a Pratt & Whitney F100-PW-229 or a GE F110-GE-129 afterburning turbofan engine. Its primary air-combat weapons include the AIM-120C-7/8 AMRAAM, AIM-9 Sidewinder, AGM-88 HARM, and AGM-84 Harpoon missile systems.

The aircraft’s advanced cockpit features multifunction displays and superimposed radar data visualization, significantly enhancing the pilot’s situational awareness. Additionally, the Block 70/72 variants incorporate upgraded avionics, the high-performance APG-83 AESA radar, conformal fuel tanks, updated mission computers, and new security systems.

Currently, around 25 countries worldwide operate various versions and blocks of the F-16 fighter jet. The U.S. Air Force alone operates approximately 897 F-16 aircraft. Other major operators include Turkey (243), Israel (224), Egypt (218), South Korea (167), Greece (154), Taiwan (137), United Arab Emirates (76), Pakistan (75), Singapore (60), Jordan (59), Belgium (53), and Thailand (50).

According to publicly available international data, between 670 and 685 F-16 aircraft have been destroyed or damaged in accidents or combat since 1978. However, considering the aircraft’s extensive global usage, high operational tempo, and large export numbers over more than four decades, these losses are generally regarded as relatively limited.

In recent years, orders for new F-16 aircraft have declined somewhat. The primary reasons include U.S. strategic and political conditions, restrictions on technology transfer, high costs, and concerns among user nations regarding operational autonomy. As a result, several countries are now considering alternatives such as China’s J-10CE, South Korea’s FA-50, or Sweden’s Saab Gripen light fighter aircraft.

Despite these limitations, the F-16 continues to hold its position as one of the world’s most effective and widely used fighter aircraft due to its versatility, reliability, and long operational track record. Consequently, the United States aims to keep upgraded F-16s in service alongside the F-35, equipping them with advanced technology, improved engines, modern radars, and especially upgraded avionics systems, to ensure operational relevance until around 2040.
