Japan's National Aerospace Laboratory plans to fly a remotely piloted supersonic-transport test model by 2002. It will fly at a speed of Mach 2 and be used to test fluid dynamics, structural characteristics and systems integration. The scaled 8-8.5m long vehicle, would be powered by one, or two, 4.45kN (1,000lb)-thrust class engines. Candidate power plants include the Teledyne YP69-T-406, the Ishikawajima-Harima Heavy Industries F3-30 and the General Electric 85-21.
