T-50 Golden Eagle South Korean Lead-In Fighter Trainer (LIFT) Aircraft

The KAI T-50 Golden Eagle (골든이글) is a family of South Korean supersonic advanced trainers and light combat aircraft, developed by Korea Aerospace Industries (KAI) with Lockheed Martin. The T-50 is South Korea's first indigenous supersonic aircraft and one of the world's few supersonic trainers. Development began in the late 1990s, and its maiden flight occurred in 2002. The aircraft entered active service with the Republic of Korea Air Force (ROKAF) in 2005. The T-50 has been further developed into aerobatic and combat variants, namely T-50B, TA-50, and FA-50. The F-50 single-seat multirole fighter variant was considered. The T-50B serves with the South Korean air force's aerobatics team. The TA-50 light attack variant has been ordered by Indonesia. The Philippines ordered 12 units of the FA-50 variant. The T-50A was marketed as a candidate for the United States Air Force's next-generation T-X trainer program but failed to win. Thailand ordered 12 units of the T-50 advanced trainer variant. The T-50 Golden Eagle design is largely derived from the F-16 Fighting Falcon, and they have some similarities. KAI's previous engineering experience in license-producing the KF-16 was a starting point for T-50 development. The trainer has seating for two pilots in a tandem arrangement. The high-mounted canopy developed by Hankuk Fiber is applied with stretched acrylic, providing the pilot's good visibility. The trainer has been tested to offer the canopy with ballistic protection against 4-lb objects impacting at 400 knots. The altitude limit is 14,600 meters (48,000 ft), and the airframe is designed to last 8,000 hours of service. There are seven internal fuel tanks with a capacity of 2,655 liters (701 US gal), five in the fuselage and two in the wings. An additional 1,710 liters (452 US gal) of fuel can be carried in the three external fuel tanks. T-50 trainer variants have a paint scheme of white and red, and aerobatic variants are white, black, and yellow. The T-50 uses a single General Electric F404-102 turbofan engine license-produced by Samsung Techwin, upgraded with a FADEC system jointly developed by General Electric and KAI. The engine consists of three-staged fans, seven axial stage arrangements, and an afterburner. The aircraft has a maximum speed of Mach 1.5. Its engine produces a maximum of 78.7 kN (17,700 lbs) of thrust with an afterburner. The more powerful F414 and EJ200 engines have been suggested as the new engine for the T-50 family
