Korea Aerospace Industries (KAI) has marked a historic milestone, rolling out the first production KF-21 Boramae fighter jet. The event, occurring less than two years after construction began and four years after the maiden flight of its first prototype, underscores Seoul’s rapid advancement in solidifying its defense capabilities.
National Aspirations Forged in Steel and Technology
The aircraft, a two-seat jet bearing the serial number 26-001, was unveiled on Wednesday at KAI’s facilities in Sacheon during a grand ceremony attended by South Korean President Lee Jae Myung. The leader emphasized that the KF-21 program „embodied the country’s aspirations to be reliant in self-defense.”
„The government will leverage this success as a solid foundation for advancing Korea into one of the top four defense-industrial nations,” President Lee stated, pledging continued heavy investment in the development of advanced aircraft engines, materials, and components. This rollout represents a significant development for the KF-21 program, which also achieved another major benchmark in January with the completion of its flight test program.
A Two-Decade Journey to the Skies
The concept for an indigenous fighter program first emerged in South Korea 25 years ago, though final approval for development was only granted in 2015. Beyond KAI, this national endeavor involves other key stakeholders, including South Korea’s Agency for Defense Development and the Korean defense giant Hanwha.
The KF-21 is classified as a 4.5 generation fighter jet and will be equipped with a mix of indigenous and Western sensors and weapons in service, notably including the KGGB precision glide bomb and the European MBDA Meteor air-to-air missile, according to South Korea’s Defense Acquisition Program Administration (DAPA).
Ambitious Plans for Air Fleet and Export Markets
South Korea has already placed an order for 40 KF-21 jets in the Block 1 configuration, primarily intended for air-to-air roles. Development is also underway for the Block 2 variant, which will expand the type’s air-to-ground capabilities, with a reported 80 additional Block 2 aircraft contracted for the Republic of Korea Air Force (RoKAF).
KAI is also actively pursuing export sales for the type, with potential markets including Indonesia – a development partner for the KF-21 – and the Philippines. The KF-21s will initially be used to replace the RoKAF’s aging F-4 Phantom and KF-5 Tiger II fighter jets. The F-4s were already retired from South Korean service in 2025, and the KF-5s are expected to follow in the coming years, marking a complete transition towards a modernized and self-reliant air force.
