KAI T-50 Golden Eagle
KAI · Advanced Jet Trainer / Light Combat / Advanced Jet Training / Lead-in Fighter Training · South Korea · Modern (1992–2009)
The KAI T-50 Golden Eagle is South Korea's first domestically developed supersonic aircraft, a lead-in fighter trainer and single-engine supersonic aircraft designed by Korea Aerospace Industries with technical assistance from Lockheed Martin. The programme launched in 1997 after South Korea concluded that training its KF-16 and F-15K pilots on subsonic jets such as the T-38 Talon left a performance gap before transitioning to Mach 2 frontline fighters. First flight was on 20 August 2002; the Korean Air Force took delivery of the first production aircraft in February 2005.
A single General Electric F404-GE-102 turbofan produces 17,700 lbf with afterburner, propelling the T-50 to Mach 1.4 at altitude and 48,000 ft service ceiling. Maximum take-off weight is 27,000 lb; the aircraft carries a 20 mm cannon and five hardpoints for gun pods, air-to-air missiles, and practice bombs. Range is 1,151 miles. Unit cost is approximately $30 million, competitive against the BAE Hawk 200 and Alenia Aermacchi M-346. The Republic of Korea Air Force has accepted 60 T-50 trainers plus 60 TA-50 lead-in fighters.
The FA-50 is the combat-capable light attack variant, with an Israeli Elta EL/M-2032 pulse-Doppler radar, air-to-air refuelling probe, and compatibility with AIM-9 Sidewinder, AIM-7 Sparrow, and AGM-65 Maverick. The Philippine Air Force operates 12 FA-50PH aircraft purchased in 2015 for $421 million and used them in combat against ISIS-affiliated militants during the 2017 Battle of Marawi — the first combat deployment of the type. Iraq acquired 24 T-50IQ aircraft configured similarly. Indonesia ordered 16 T-50i; Poland contracted 48 FA-50s in 2022 at $3 billion, the largest export order in the programme's history.
KAI's export marketing frames the T-50 family against the BAE Hawk 128 and Leonardo M-346 in the supersonic jet trainer segment and against the Textron AT-6 Wolverine in the light attack role. South Korea is developing the KF-21 Boramae as the T-50's eventual successor in the light-to-medium combat role; the T-50 family itself continues in production with deliveries to Poland and a prospective Malaysian order under evaluation in 2026.
For Kids — a shorter, friendlier version
The KAI T-50 Golden Eagle is a supersonic jet trainer made in South Korea. A jet trainer teaches pilots to fly fast jets before they move to real fighters. South Korea built the T-50 together with the American company Lockheed Martin. It first flew in 2002.
The T-50 has two seats — a student pilot in front and an instructor behind. It can break the sound barrier, going faster than a rifle bullet at top speed. Very few trainers in the world can do that. This lets it teach the skills pilots need for the fastest jets in service today.
A version called the FA-50 carries radar, missiles, and bombs. Countries like the Philippines, Poland, and Iraq fly it as a fighter jet. South Korea's Black Eagles team uses a display version at air shows.
The T-50 is a big achievement for South Korea. It shows the country can design and build a world-class fast jet. Today it is sold to air forces around the world.

Kids’ Questions
Why do fighter pilots need a special trainer jet?
Learning to fly a jet is done in steps. Pilots start on slow propeller planes to learn the basics, then move to faster and more powerful jets. A supersonic trainer like the T-50 bridges the gap between a basic jet trainer and a full fighter. Pilots practice handling high speed, high G-forces, and complex instruments before they are trusted with the most expensive frontline jets. Skipping these steps would be like going from a bicycle straight to a racing car with no practice in between.
What are G-forces?
G-force is the feeling of being pushed into your seat when a plane or car accelerates quickly. In normal life you feel one G — the pull of gravity. A fighter pilot pulling out of a steep dive or turning sharply might feel six or seven Gs — like six times their body weight pressing down on them. At high G, blood is forced away from the brain, and pilots can briefly lose vision or consciousness. Special G-suits squeeze a pilot's legs and belly to keep blood in the brain and are practised in trainer jets before combat flying.

Frequently Asked Questions
What is the difference between the T-50 and FA-50?
The T-50 is a pure trainer with no fire-control radar or combat avionics. The TA-50 adds a basic fire-control suite and weapon hardpoints for lead-in fighter training. The FA-50 is a full light combat variant with an Elta EL/M-2032 pulse-Doppler radar, air-to-air refuelling probe, and compatibility with AIM-9 Sidewinder, AIM-7 Sparrow, and AGM-65 Maverick air-to-ground missiles.
What was the T-50's first combat use?
Philippine FA-50PH aircraft flew combat sorties against ISIS-affiliated Maute Group militants during the Battle of Marawi from May to October 2017. The FA-50 conducted close air support and armed reconnaissance missions in support of Philippine Army ground forces. It was the first armed conflict use of the T-50 family and demonstrated the FA-50's practical light strike effectiveness.
Why did Poland buy the FA-50?
Poland contracted 48 FA-50PLs in 2022 at $3 billion as an interim strike aircraft after retiring its Soviet-era Su-22 fleet following Russia's invasion of Ukraine. Poland's F-35As were not due until 2024–2026, leaving a gap the FA-50PL was purchased to fill. Poland also ordered 32 additional FA-50PLs in an enhanced configuration for longer-term service.
How does the T-50 compare to the <a href="/v/bae-systems-hawk.html">BAE Hawk</a>?
The T-50 is supersonic (Mach 1.4) while the Hawk tops out at Mach 1.2 in the 128/200 combat variant. The T-50/FA-50 carries a more capable radar and heavier avionics suite than the Hawk 128, reflecting its dual role as a trainer and light fighter. The Hawk is cheaper per aircraft at around $20–24 million versus $30 million for the T-50 and has a longer global service history.
What is the T-50's relationship to the <a href="/v/f-16-fighting-falcon.html">F-16</a>?
Lockheed Martin provided significant technical assistance to KAI for the T-50 programme, including fly-by-wire flight control software derived from the F-16's system, cockpit avionics designed to replicate F-16 procedures, and overall aircraft configuration guidance. The T-50 was deliberately designed to transition ROKAF pilots smoothly to the KF-16, and later to the F-15K and future KF-21 Boramae.
