The U.S. Air Force has begun moving F-16 Fighting Falcons from Osan Air Base back to Kunsan Air Base in South Korea, reversing part of a year-long force posture experiment on the peninsula. Imagery released on 28 September showed the latest phase of the relocation, which follows an aircraft departure from Osan on 15 September and restores a more distributed fighter layout across the two bases.
The move ends the “Super Squadron” test that concentrated additional F-16s at Osan to examine whether a larger fighter formation could improve sortie generation, maintenance, training and logistics. The reset returns Seventh Air Force to a three-squadron structure split between Osan and Kunsan, with the 8th Fighter Wing at Kunsan regaining combat airpower after the experiment had drawn aircraft south-east towards Osan.
The posture shift is intended to improve operational flexibility and sustain readiness by avoiding over-reliance on a single location during a crisis. It also fits the wider U.S.-South Korea defence posture on the Korean Peninsula, where F-16 units remain central to the “Fight Tonight” mission. Pacific Air Forces had already judged the test complete earlier in 2026, paving the way for the phased return of aircraft to Kunsan.
