South Korea's Indigenous Fighter Program Enters Operational Service Amid Global Interest

South Korea is preparing to deliver the first production KF-21 Boramae fighter jets to the Republic of Korea Air Force (ROKAF) in 2026. The deliveries mark the transition of the country’s flagship combat aircraft program from development to operational service. According to South Korean media, the first serial-production aircraft are expected to be handed over following the completion of acceptance testing. The KF-21 program has been one of South Korea’s most ambitious defense projects, aimed at replacing aging F-4 Phantom II and F-5 Tiger II fleets while reducing reliance on foreign combat aircraft. AeroTime reports that the initial deliveries will consist of Block I aircraft optimized primarily for air-to-air missions.
