T-50 Completes 100th Test Flight

The T-50 Golden Eagle, an advanced supersonic trainer developed by Korea Aerospace Industries (KAI) with the assistance of Lockheed Martin , has completed its 100th test flight.

"The T-50 development program continues right on track, and we are beginning to accelerate our flight test program with our two aircraft," said No Sun Park, director & plant manager of KAI's Sachon plant. "We successfully accomplished three flights on the day we flew the 100th flight. On one of those flights, we reached a speed of Mach 1.2 [1.2 times the speed of sound] for the first time. These are both important milestones for the Republic of Korea's consideration of the Initial Production Authorization later this year."

The ground testing program is also on schedule. On April 25, the airframe durability vehicle completed one lifetime of testing, equivalent to 8,334 flight hours. The 100th test flight was completed on April 28. Durability testing is being conducted at the Agency for Defense Development testing laboratory in Taejon, South Korea, and began on schedule July 22 of last year. Testing continues on a second lifetime, which is expected to be completed in April 2004.

The T-50 Golden Eagle is being developed by KAI for the Republic of Korea Air Force. Lockheed Martin, as principal subcontractor to KAI, is providing technical expertise for the program and is responsible for developing the T-50 avionics system, flight control system and wings. The two companies are cooperatively marketing the T-50 internationally.

The T-50 Full-Scale Development program began in 1997 and will continue through 2005. Initial production authorization is planned for the latter part of 2003 with production deliveries to begin in 2005.

The T-50 will have the maneuverability, endurance and advanced systems to prepare future pilots to fly current and next-generation fighters like advanced F-16s, the F/A-22 and the F-35 Joint Strike Fighter. These same characteristics give it an excellent capability as a lead-in fighter trainer and potential light-combat aircraft derivative in many air forces.
