KAI Secures Additional KF-21 Fighter Jet Order and Engine Deal

In a major boost to South Korea’s indigenous fighter jet program, Korea Aerospace Industries (KAI) has secured a contract to produce an additional 20 KF-21 Boramae fighter jets for the Republic of Korea Air Force (ROKAF).

The deal, valued at 2.39 trillion won (approximately $1.75 billion), was awarded by South Korea’s Defense Acquisition Program Administration (DAPA) and is the second production batch following the initial order signed in July 2024 for 20 aircraft worth 1.96 trillion won (about $1.4 billion).

KF-21 Fleet Expansion Targets 120 Jets by 2032

Deliveries under the new contract will be completed by 2028, aligning with ROKAF’s long-term plan to field 120 KF-21s by 2032. Despite a noticeable cost increase between the two orders, the KF-21 remains cost-effective compared to other 4.5- and 5th-generation fighters, such as the Dassault Rafale, Saab Gripen, and Lockheed Martin F-35.

The rising interest from countries like Peru, the Philippines, and the UAE further highlights the KF-21’s emerging position in the global defense export market. However, the pricing dynamics have sparked some internal debates on the program’s long-term affordability and market competitiveness.

Advanced Capabilities and Strategic Role

The KF-21 Boramae is a 4.5-generation multirole fighter jet designed to replace South Korea’s aging F-4 Phantom II and F-5 Tiger II fleets. Developed under a $6.8 billion initiative launched in 2015, the jet features advanced avionics, limited stealth shaping, and multi-mission capability, offering both air superiority and precision strike functionality.

The KF-21 can carry a wide array of modern weaponry, including air-to-air missiles, precision-guided bombs, and a cannon. DAPA also recently confirmed a successful test of a domestically developed long-range air-to-surface missile, designed specifically for integration with the KF-21, further extending the platform’s deep-strike range.

Hanwha Aerospace Secures Engine Contract

In parallel with the fighter jet order, Hanwha Aerospace has signed a contract to supply 40 General Electric F414 engines—valued at 623.2 billion won ($450 million). This deal includes not just the engines but also spare parts and maintenance support, ensuring sustainable performance over the fleet’s life cycle.

The F414 engine, which also powers the F/A-18 Super Hornet and Gripen E/F, generates 44,000 pounds of thrust. With twin engines, the KF-21 can achieve speeds of Mach 1.8 (approximately 2,200 kilometers per hour), supporting high-speed interception and multirole combat operations.

A Milestone in South Korea’s Defense Modernization

These back-to-back contracts reinforce South Korea’s commitment to defense self-reliance and technological advancement. As the KF-21 program gains momentum, KAI and its partners—including Hanwha and DAPA—are positioning the Boramae as a powerful domestic asset and a promising export product.

With continued success in development, production, and testing, the KF-21 is set to become a key pillar of the ROKAF’s future air combat strategy and a notable competitor in the global fighter jet market.
