Mitsubishi began work on the aeroplane in April of the same year, and the aircraft finally emerged as an inherently unstable type with a triplex digital fly-by-wire control system tied into the standard control surfaces (modified with carbon fiber "flaperons" and leading edge flaps) as well as two movable canard surfaces on the inlet trunks forward of the wings and, in line with these surfaces but under the fuselage, a vertical fin.
Powered by two 7,066 lb (3,205 kg) st Ishikawajima-Harima TF40-IHI-801A (license-built Rolls-Royce Turboméca Adour Mk.801A) turbofans, the T-2CCV first flew in August 1983, and a successful test program yielded valuable results in control augmentation, relaxed static stability, maneuver load control, direct lift control, and direct side-force control."
