The Japanese defense ministry has published a new design for the country’s next fighter. Project code name - Godzilla (Just kidding). It is expected to be bigger than the F-22 with emphasis on greater payload and range.

The Japanese defense ministry has published a new design for the country’s next fighter, suggesting an even greater emphasis on range and payload than before.

An illustration of the design differs markedly in planform from the most recent that has previously been shown, which was called 26DMU and prepared in fiscal 2014. The new design is somewhat reminiscent of concepts for the proposed Future Combat Air System and Tempest fighter programs, the former led by France and Germany and the latter by Britain. The Tempest is a possible basis for NGF.

Whereas 26DMU had four tail surfaces, somewhat slanted, the NGF drawing in the budget report shows only two; they are mounted at perhaps 45 deg. to the vertical.

The mainplane also is dramatically different, with seemingly higher aspect ratio (slimness). The leading edge is straight, as before, but the trailing edge is swept forward inboard but aft outboard—as on the wings of the Tempest and FCAS concepts and, before them, the unsuccessful McDonnell Douglas submission for the Joint Strike Fighter program in the 1990s and the McDonnell F-101 Voodoo of the 1950s.

The trailing edge of the newly revealed Japanese design meets the fuselage at about the same point as the leading edges of the tail surfaces, as in FCAS concepts published by Dassault. In the Tempest concept that Britain has revealed, the mainplane, with much lower aspect ratio than the Japanese design, is extended as far back as the trailing edges of the tail surfaces.

IHI Corp. and the ministry have developed an engine of at least 33,000 lb. thrust, the XF9-1, for the fighter.

That looks like 24DMU ( Digital Models) :

The 23DMU, 24DMU and 25 DMU:

The 26DMU seems to be :

and

Therefore these (non digital) Models fit for Wind Tunnels:

Note : Above images were taken by google image search with the keyword "26DMU"

I think Japan's latest ( assuming 26 DMU is the latest one and there isn't a 27 DMU) shows little divergance from the design of F-35 or F-22.
So... is the model with the unique wing design ( like Voodoo ) the 27DMU ?

I think an estimate of the F-35 total development is $70 (seventy) billion (LOL I set aside its salami slicing into Blocks so that the Pentagon/LockMart can claim decreasing per-copy price), and off top of my head I don't know the F-22 total development cost, but the money I see in this and previous page are laughable

The japanese X-2 shinshin, which is a testbed of sorts that, personally i think, point to the ultimate lay of the land (or design) regarding the F3.

In fact, if the design was like the 24DMU, without horizontal stabilators, wouldn't there be that provision for X-2 shinshin ? A fighter jet with a V tail that doesn't have Horizontal stabilators are rare ( I know Delta wings like Mirage 2000, Tejas that are there, also not having canards). That more challenging for Japan who doesn't have any experience with such a configuration. But that can be undone by testing some prototypes BUT THEN...
Why would Japan, that has not so covertly expressed agony over funding issues, forfeit the chance for testing a V tail only design (similar to that of YF-23) by choosing to test the X-2 shinshin ? Has there been a change of design AFTER the X-2 flights ?

I want to know if this is the 27DMU. Is it the 28DMU. Why ?
Has there been an yet to be announced collaboration with UK tempest program? Is Northrop Grumman finally getting aboard the F3 project ?

This was floated by Jiji press when they were reporting the 2020 budget.

I'm more curious about the light colored patterns that is on the surface of this plane.
if they are electronic plasma generators then it could be

making the plane able to turn anyway it wants without the need of rudders or any other mechanical air flow displacement mechanism.
The thrust vectoring would work in tandem with it.

I was wondering too on those patterns. It is possible that the F-3 might incorporate those features as laminar flow technology has been progressing.
