SEOUL-<\/strong> South Korea<\/a> has rolled out the first series-produced KF-21 Boramae fighter jet, marking a major milestone in the country’s push for self-reliant defense. The ceremony took place at Korea Aerospace Industries (KAI) headquarters in Sacheon, just over five years after the prototype was unveiled in April 2021.<\/p>\n\n\n\n

President Lee Jae Myung attended the event and reaffirmed South Korea’s goal of becoming one of the world’s top four defense powers, highlighting the KF-21 as proof that the country can now defend its skies with domestically developed technology, TWZ<\/a> reported.<\/p>\n\n\n\n

South Korea’s KF-21 Boramae Enters Series Production<\/h2>\n\n\n\n

The KF-21 program was formally launched in 2016<\/strong>, with the first prototype rolled out in April 2021 and its maiden flight completed in July 2022.<\/p>\n\n\n\n

By May 2023, the jet was provisionally declared fit for combat. Six prototypes in total have been built and flown, including two two-seat variants.<\/p>\n\n\n\n

The first series-produced example is a two-seater, reflecting the growing importance of the two-seat configuration for future crewed\/uncrewed teaming missions. The Republic of Korea Air Force (ROKAF) plans to receive 40 KF-21s by 2028<\/strong>, with a full fleet of 120 aircraft in service by 2032<\/strong>.<\/p>\n\n\n\n

A “4.5-Generation” Fighter by Design<\/h2>\n\n\n\n

South Korea deliberately positioned the KF-21 as a 4.5-generation fighter<\/strong> rather than a full fifth-generation platform. This decision allowed KAI to avoid the costly and time-intensive stealth-focused design processes that have delayed programs like the F-35 and Russia’s<\/a> Su-57.<\/p>\n\n\n\n

Unlike the F-35, the KF-21’s airframe is not primarily shaped by stealth requirements, and its sensor fusion is less advanced. However, this is a calculated trade-off.<\/p>\n\n\n\n
