Le démonstrateur Shinshin X-2 de Mitsubishi

https://en.wikipedia.org/wiki/Mitsubishi_X-2_Shinshin

The ATD-X will be used as a technology demonstrator and research prototype to determine whether domestic advanced technologies for a fifth generation fighter aircraft are viable.[19] The aircraft features 3D thrust vectoring capability. Thrust is controlled in the ATD-X by three paddles on each engine nozzle similar to the system used on the Rockwell X-31, while an axis-symmetric thrust vectoring engine is also being developed for the full-scale production model.[19]
