CHIBA -- Mitsubishi Heavy Industries (MHI) is working on a next-generation military trainer jet with an eye on overseas sales as other nations begin to take an interest in Japan's efforts to increase defense exports and create a sustainable defense industry.

The T-X concept jet was unveiled during DSEI Japan, a three-day defense equipment trade show that started on Wednesday. The two-seater, twin-engine subsonic trainer is being pitched as a successor to the current T-4 jet. The Japanese Ministry of Defense is expected to select the contractor in the coming years.
