I know orig
and that is a large scale model, not the full size aircraft.
Initially they had static models that were smaller...but I thought this was a full sized demonstrator? The current prototype of the aircraft size is:
In July of 2014 it was announced that the ATD-X technology demonstrator had completed its static testing phase during 2013. The vehicle was then rolled out in May of 2014 to begin its formal evaluation to test its advanced design features - this will lead the program into 2016 and a flight test. Engines have been verified as 2 x IHI XF5-1 turbofan engines of 11,000lbs thrust each. The airframe is compared to the size of the Saab Gripen multirole fighter.
I think the idea is to test all of the relevant functions with this demonstrator/prototype and then lead to a F-3 fighter aircraft for actual production beginning in the 2020s.
Samurai?
This aircraft (and perhaps 1-2 more) would be used for a research prototype to determine whether Japan can produce the advanced technologies for a fifth generation aircraft that are viable.
The demonstrator is going to have 3D thrust vectoring using three paddles on each nozzle similar what Roockwell used on the X-31. An axis-symmetric thrust vectoring engine would be being developed for production aircraft.
Also, this prototype would have fly-by-optic flight control, using optic fiber instead of wires which means data transfer would be immune to electromagnetic measures.
It's going to have a new AESA radar called the 'Multifunction RF Sensor', with broad spectrum agility. Additional capabilities to be tested are new and capabilities for ECM, ESM, communications, and perhaps microwave weapon functions.
The Japanese want to also develop a "Self Repairing Flight Control Capability," to allow the aircraft to automatically detect failures or damage in its flight control and use other control surfaces, calibrate to retain controlled flight,
Pretty impressive plans.
