South Korea has unveiled plans to significantly expand its air combat capabilities with the domestic production of up to 120 KF-21 Boramae fighter jets by the early 2030s. As part of the phased production schedule, the first batch—consisting of about 20 aircraft—is expected to be delivered to the South Korean military between 2026 and 2027. This initiative is a cornerstone of Seoul’s push for defense self-reliance and modernization of its aging aerial fleet.
The KF-21, developed as an indigenous multirole fighter, is poised to replace the aging fleet of American-made F-4 Phantom and F-5 Freedom Fighter aircraft currently in service. Boasting modern specifications, the aircraft measures 17 meters (57 feet) in length, with a wingspan of 11 meters (36 feet), and it can hold up to 6,000 kilograms (13,228 pounds) of fuel.
Equipped with two Hanwha/GE F414 engines, the jet delivers a combined thrust of 110,000 horsepower, allowing for high-speed and long-range operations. It can reach speeds of Mach 1.8 (2,223 km/h or 1,381 mph) and operate at altitudes as high as 16,700 meters (54,790 feet). With an operational range of 1,500 nautical miles (2,778 km), the KF-21 is expected to play a crucial role in ensuring regional air dominance for South Korea well into the next decade.
