I'm not trolling at all. I just point something obvious
You are somewhat right. Japanese Surface combatants could be considered AB derivatives as they share a lot of U.S systems as well as basic Hull design. But they are also indigenous in the sense that many subsystems and armaments are either japanese license production variants, improved japanese variants or is truly indigenous. I wouldn't call them an "AB with a japanese flag" though. That's a bit out there.
There is no elitism here in this forum. If there is, it could be earned by contributing new original information/posts regarding the topics discussed.
I wanted a separate thread for the Japanese i3 fighter program. Japan has made good progress regarding many specific subsystems related to the program. I think the Japanese project may come out with a big bang. Make sure that we aren't the bit surprised that we create a sperate thread for i3 / future Japanese stealth Air Combat platform?
Bit like Sino Flankers, they're somewhat same case. Thats why J-11 is called Flanker L and there is nothing bad at all. Maybe I surprised by the aesthetics of Asif. Akizukis i believe are more beautiful even though the passe AB outfit

You are right in that Japan is making good progress in maturing the various important technologies associated with their NG fighter i.e. the F-3. The current plan is to have a prototype flying by 2025. Their 2020 fiscal budget would likely officially kick off the program even though there are unresolved residual politics concerning key program requirements like range and radar capabilities.
Some of the progress made to-date concerning key components include :
Concept Design Planform
The indigenous design may perhaps be based on the twin-engine 26DMU. The latest concept design of Japan’s proposed indigenous fighter may have moved a little away from the bias toward long-range and endurance over flight performance. The main change relative to the 25DMU design appears to be a reduction in the span of the wing and, as a result, its unusually high aspect ratio. The leading-edge sweep of 26DMU looks unchanged, but the trailing edge is different: It now has a forward instead of rearward sweep. Associated with that change, the chord at the wing roots looks longer, again implying a reduction in aspect ratio. Higher aspect ratio improves range and endurance but worsens drag in supersonic flight.
Sensors
Japan has flight tested an integrated suite of sensors for its NG fighter, creating a single fusion system from a gallium-nitride radar, a passive radio-frequency (RF) sensor and an infrared camera. The unnamed system was built into a MHI F-2 and tested in the air from May to July 2019.
The developmental system is the product of a 10-year effort aimed at overcoming the difficulty of detecting stealthy targets.
Weapons Bay
Japanese engineers have overcome the challenge of designing a weapon bay for supersonic release of stores. The Japanese ministry has reported release tests were conducted at Mach 1.4. A critical design objective has been achieving high but undisclosed speed in the four-step cycle of door opening, weapon ejection, launcher retraction and door closing.
The internal bay is expected to be able to carry six Meteors
Engine
The engine is derived from the IHI XF9-1 technology demonstrator. Government defense engineers since July 2017 has begun ground testing of the proposed XF9-1 engine. Specifically, the XF9-1 engine, built by IHI has reached its required dry rating of 11,000 kg (24,000 lb.) and afterburning output of 15,000 kg, according ATLA, which is overseeing the program. The XF9-1 is capable of supersonic cruise.
In fiscal 2019 the demonstrator is scheduled to be moved to Chitose, on the northern island of Hokkaido, for altitude testing—still on the ground. This is intended mainly to confirm the engine can be restarted in flight, but some details on performance at altitude will be acquired as well.
The most notable feature of the engine design is that it does use a diverter, which splits the turbulent boundary layer from the air that enters the inlet in contrast to the diverterless design of the F-35.
Structure
The skin of a modern fighter may be made of carbon-fiber-reinforced plastic, to save weight, but underneath there is still a lot of metal. Japanese engineers, working on replacing fasteners with glue, are applying composite to the substructure as well as to the skin.
A full-scale midfuselage has undergone strength testing as part of the technology acquisition effort. The test specimen is built up from modules in which composite skin is glued to composite frames and beams that are themselves joined to each other with adhesive.
Evaluation results have not been disclosed but so far no major problem has arisen, says an official of the defense ministry’s ATLA, which is undertaking the work in partnership with MHI. Testing is due to end on March 31, 2019. The technology is difficult, says the official, suggesting more time may be needed.
