The T-50 was developed by Korea Aerospace Industries, Ltd., with cooperation and global marketing support from Lockheed Martin. Both firms were aware that many training aircraft fleets are aging, even as higher-performance fighters demand trainer aircraft that can keep up. The Korean government needed a fleet of trainers, and saw an opportunity to give their aerospace sector a strong boost in the process. Total investment in the T-50’s RDT&E program amounted to more than $2 billion: 70% from the Korean government, 17% from KAI, and 13% from Lockheed Martin.
With a length of 43 feet and a wingspan of 30 feet, the 2-seat T-50 is about 4 feet shorter than the F-16; overall, it’s only about 80% of the F-16’s size. The relative size of the control surfaces and tails are larger, however, to improve handling characteristics at lower speeds and make the aircraft easier to land. Larger landing gear is also fitted, to absorb harder landings, which is to be expected from student pilots. Its form’s resemblances to Lockheed Martin’s F-16 are suggestive, and include the blended mid-set wing, complete with leading-edge root extensions and rear ‘shelf’ fairings ending in F-16-style split airbrakes.
The air intake layout on the sides is somewhat similar to the F/A-18 Hornet or Northrop’s excellent but ill-fated F-20A Tigershark, and the aircraft is powered by the same engine: GE’s popular, reliable and fuel-efficient F404, with slight improvements over the F404-GE-402 to enhance single-engine redundancy and reliability.
The T-50 trainer carries a basic navigation / attack system, which gives it some multi-role capability. The aircraft can carry Sidewinder missiles on the wingtips, as well as fuel, rockets, or qualified bombs on its 5 underwing and center pylons. the center pylon and 2 inner underwing pylons are “wet,” and can accommodate 150 gallon fuel drop tanks.
The T-50 family’s empty weight is 14,000 pounds, and maximum takeoff gross weight is 29,700 pounds; the F404-GE-102 engine produces 17,700 pounds of thrust. Maximum rate of climb is 39,000 feet per minute; and the maximum speed is Mach 1.5. Service ceiling is 48,500 feet, the design load factor is 8gs, and the trainer airframe is designed for up to 10,000-hour service life
