South Korea is accelerating the development of the KF-21 Boramae, a next-generation fighter jet designed to strengthen its air capabilities and reduce dependence on foreign aircraft.
Produced by Korea Aerospace Industries (KAI), the jet represents a significant technological leap for the country and draws comparisons with the F-35 Lightning II from Lockheed Martin.

The KF-21 Boramae is equipped with an AESA (Active Electronically Scanned Array) Radar, one of the most advanced technologies in military radars. This system is one of the key differentiators of the South Korean fighter jet, providing greater detection and tracking capabilities compared to conventional radars.
Comparison with the F-35
| Feature | KF-21 Boramae | F-35 Lightning II |
|---|---|---|
| Generation | 4.5+ | 5th generation |
| Stealth | Partial | Full |
| Speed | Mach 1.8 | Mach 1.6 |
| Engines | 2x GE F414 | 1x Pratt & Whitney F135 |
| AESA Radar | Yes | Yes |
| Weapon Capacity | External | Internal and External |
| Estimated Price | US$ 65 million | US$ 100-120 million |
Interesting Facts
- The name “Boramae” means “Hunting Falcon” in Korean.
- Indonesia initially financed 20% of the project but faced difficulties maintaining payments.
- The KF-21 may eventually include an internal weapons bay to enhance stealth capabilities.
- The fighter jet has greater maneuverability compared to the F-35 due to its twin-engine design.
Conclusion
The KF-21 Boramae represents a significant advancement for South Korea’s aerospace industry. Although it does not directly rival the F-35, it offers a more accessible and independent option. If South Korea develops future versions with greater stealth and autonomy, the KF-21 could become an even stronger competitor in the global market.
