About the Dassault Falcon/Mystère 50

The KAI FA-50 Fighting Eagle is South Korea's first indigenous supersonic fighter, a light attack aircraft derived from the T-50 Golden Eagle advanced jet trainer. Developed by Korea Aerospace Industries in partnership with Lockheed Martin, the FA-50 entered service with the Republic of Korea Air Force in 2013 and has since become a successful export platform, combining advanced training capability with genuine combat punch in a cost-effective package. Powered by a single General Electric F404 turbofan, the same engine that powers the F/A-18 Hornet, the Fighting Eagle can reach Mach 1.5 and carry a respectable weapons load including AIM-9 Sidewinders, AGM-65 Mavericks, and precision-guided bombs on seven hardpoints.

What distinguishes the FA-50 in the light fighter market is its modern glass cockpit with multifunction displays, Link 16 datalink capability, and AN/APG-67(V)4 pulse-Doppler radar, giving it beyond-visual-range awareness that rivals far more expensive platforms. The type has found favor with air forces seeking an affordable multirole solution: the Philippines, Thailand, Poland, and Malaysia have all ordered the Fighting Eagle, with Poland's 48-aircraft deal representing the largest export contract and marking the type's entry into NATO service. In the United States, a small number of FA-50s operate in civilian hands under experimental or restricted category certificates, often for adversary support training or private advanced jet operations, explaining the N-registered tails in the dataset.
