USAF F-16s in South Korea are starting to receive the APG-83 AESA radar upgrade

USAF F-16s stationed in South Korea are receiving major upgrades to their radar and avionics systems as part of the Post Block Integration Team project. The project is aimed at improving the lethality and survivability of the F-16s to meet the needs of current and future operations. The APG-83 Scalable Agile Beam Radar (SABR) with active electronically scanned array and the Center Display Unit (CDU) are the main components of the upgrade that will give pilots a clearer picture of the threat environment, ultimately increasing both the survivability and accuracy of the weapon system.

One upgraded F-16C, # 89021, has already rejoined the 8th Fighter Wing after receiving the first wave of 22 modifications, including avionics upgrades, a new-generation electronic warfare capability, a communications suite upgrade, and a modernized mission computer. The upgraded systems provide pilots with improved situational awareness, reduced workload, and improved effectiveness for all aspects of flight.

According to Col. John D. Caldwell, 8 FW vice commander, the upgrades will keep the F-16 relevant to the fight, as the F-16 is planned to continue service into the 2040s. The upgrades will also expand the F-16’s participation in future operations, playing a large role in the future of F-16 support for Combatant Commanders across the area of operations.

The PoBIT upgrades for the F-16 fleet will be conducted in various phases over the next couple of years to provide the necessary updates while ensuring operational requirements can still be met. The upgrades are critical to keeping pace with the evolving threat environment and maintaining the F-16’s relevancy in the fight.
