Upgraded F-16 rejoins 8th FWPublished April 9, 2023

                    8th Fighter Wing Public Affairs
            **OSAN AIR BASE, South Korea (AFNS) --**After receiving the first phase of one of the largest **modernization efforts** in U.S. Air Force F-16 program history, an upgraded **F-16 Fighting Falcon** rejoined the 8th Fighter Wing, April 4.
Wolf Pack tail no. 021 returned to 8th FW operations after about seven weeks away for maintenance, where the **Air Force Life Cycle Management Center’s** **Post Block Integration Team** project, provided the aircraft with the first wave of 22 modifications designed to improve F-16 lethality to meet the needs of current and future operations.
Piloting WP 021 for its first operational flight back with the Wolf Pack, U.S. Air Force **Col. John D. Caldwell**, 8th FW vice commander, experienced firsthand what the updated systems brought to the platform.
“The upgraded equipment I flew with today greatly improved my situational awareness allowing me to receive and process information at a much faster rate than other F-16s in the past,” Caldwell said. “The information was quick, reliable and presented on the new displays in a way that reduced my workload and improved effectiveness for all aspects of the flight.”
The main feature of the PoBIT upgrade is the installation of the APG-83 Scalable Agile Beam Radar with active electronically scanned array and the Center Display Unit-technology that ultimately gives the F-16 and its pilot a clearer vision of the threat picture to increase both the survivability and accuracy of the weapon system.
“The F-16 is planned to continue service into the 2040’s, so this upgrade is critical to making sure we are keeping pace with the evolving threat environment,” Caldwell said. “The main components that I interacted with today [the CDU and APG-83 SABR] are both critical pieces that work together to bring the F-16 closer to fifth-generation capabilities, which will keep the F-16 relevant to the fight.”
Other notable upgrades to the platform’s avionics from this round of PoBIT upgrades included a programmable data generator, new-generation electronic warfare capability, a communications suite upgrade and a modernized mission computer.
“The avionics upgrades allow pilots to take full advantage of the jet's advanced weapons and sensors, it is capable of providing high speed data and/or high-resolution video and ultimately aids the pilot in tactical decision making,” said U.S. Air Force Capt. Michael C. Durham, 8th Operations Support Squadron weapons tactics officer. “The upgraded radar, specifically, allows us to track a greater number of targets at longer ranges in both cooperative and non-permissive environments while also improving the F-16’s all-weather capabilities by adding synthetic aperture radar mapping for target nomination and engagement.”
Durham, who took the lead on testing the jet’s system upgrades upon its return to the Wolf Pack fleet, said the upgrades will expand the F-16’s participation in future operations.
“These PoBIT upgrades play a large role in the future of F-16 support for combatant commanders across the area of operations,” Durham said. “The survivability and lethality improvements these modifications provide factor into determining which conflicts the F-16 will participate in and in what capacity, which greatly expands our leaders’ options in contingency planning to support national security objectives.”
The aircraft was the first **7th Air Force** F-16 to return to flight operations with PoBIT upgrades and, as the rest of the fleet follows suit, the modernization effort will improve the USAF’s ability to safeguard a free and open Indo-Pacific region and the stability of the Korean Peninsula.
“With regards to the Wolf Pack’s ‘Take the Fight North’ mission, these upgrades primarily allow us to keep pace with near-peer threats, but also have a large hand in the deterrence mission,” Caldwell said. “It will definitely be a part of the decision calculus for the Democratic People's Republic of Korea, because the more lethal and survivable we can make our forces here on the peninsula, the more likely we are to deter aggression. The goal is to present a force so capable, that [the DPRK] decides, instead of pulling a trigger, to pick up the phone to talk. Of course, if deterrence breaks down, the modernization program will significantly improve our ability to defend South Korea and take the fight north, if necessary.”
PoBIT upgrades for the F-16 fleet are being conducted in various phases over the next couple of years to provide the aircraft the necessary updates while ensuring operational requirements can still be met.LR
