South Korea Orders Initial Batch of KF-21 Boramae Fighters, Marks Major Milestone"

 

South Korea has taken a significant step in its defense capabilities by ordering its first batch of KF-21 Boramae fighter jets, nine years after the project's inception. The government has signed a contract with Korea Aerospace Industries (KAI) for the production of 20 jets. KAI has reported that the fighter’s development is 80% complete.

The Defense Acquisition Program Administration (DAPA) awarded KAI a contract worth 1.96 trillion won (U.S. $1.41 billion) for the Block 1 batch of the KF-21, classified as 4.5-generation aircraft. The first delivery is scheduled for the end of 2026, with the final aircraft from this series expected by August 31, 2027.

KAI President Kang Goo-young acknowledged the collaborative efforts that have enabled the project to reach mass production. Jinseok Song, a member of KAI's KF-X program management team, stated last year that the company plans to produce 40 KF-21 Block I and 80 Block II aircraft. However, DAPA has initially ordered 20 jets, based on recommendations from the Korea Institute for Defense Analyses. The government may order an additional 20 jets next year after further performance verification. The KF-21 will replace South Korea’s retiring F-4 and F-5 fighters.

Block II production, slated for 2026-2028, will enhance the KF-21 with air-to-ground capabilities and expanded performance. About 2,200 test sorties are planned by 2026.

KAI has been preparing for this contract by establishing a supply chain with 600 domestic companies, building production facilities, and acquiring necessary tools. The company aims for a 65% localization rate, anticipating an increase in domestic production as the aviation industry ecosystem strengthens with the KF-21's mass production.

In addition, DAPA has signed a contract with Hanwha Systems for 20 active electronically scanned array radars worth 110 billion won. Hanwha Aerospace has also secured a 556 billion won contract to produce 40 General Electric F414-GE-400 engines and spares for the KF-21s. The first engine is expected by the end of 2025 from a new factory in Changwon, which aims to produce 300 engines annually.

Hanwha Aerospace has manufactured over 10,000 aircraft engines in the past 45 years, with 82% produced under license. This contract is seen as a stepping stone for developing next-generation engine technologies. Looking ahead, KAI plans to advance sixth-generation manned and unmanned system technologies.
