J7W2 (the paper plane that was about [■■■■■■■■□□] 80% complete, despite not being designed yet)

2 of very many, the bigger issue is does the tech-tree need it or not? I would argue that Japan has holes in their lineup, also sooner or later they will probably reach the bottom of the barrel…

R2Y2 just got removed for the reason they’re unrealistic (base on the Propelled R2Y1 project, that had been prototyped)

New players can’t got them anymore.

And F-16AJ is simply a F-16A ADF block 15, with some features of the F-16A Blk10 (ground attack) both of which existed, so data are realistic.

(The current F-16AJ project expected to add pylons for missiles onto Gear doors, thing that we don’t have in game, because it hasn’t been made onto any real F-16)

It is also a Gap aircraft that might get deleted once the Mitsubishi F-2 is added.

J7W2 or 3 have no blueprints at all,… as you said already, the J7W2 didn’t even got to Drawing boards.

I agree that the R2Y2 is a bit unrealistic the V2 and V3 looks like Korean War era designs, however I do not think removing these planes is the solution due to Japans lack of airplanes…

I think something more grounded in reality would be better Ki-162 is for example just a copy of He-162 there is few reasons that could not have worked for example. (that airplane is even less likely but still very realistic)

Edit: J7W1 proves it would work, Yak-15 needed more modifications than the J7W1 would need and yet it fly just fine.

Many other sub trees can get added, last one is Thailand, but a South Korean one can be aswell, to give japan some:

F-86F
F-5E
F-4D and E phantom II (some E were still in service up to 2024, so there might be some interesting upgrades)
T-33 Shooting Star (biplace F-80)
A-37 Dragonfly (already in game as BP event aircraft)

And for later aircrafts:
F-15K
F-16C blk 52
FA-50
F-35
KAI KF21 Boramae

And to replace R2Y2 the T-33 and A-37 would be plenty

Foreign planes is not really Japanese ones, the licence built ones are a bit better. Oh and I do not think adding Korean sub-tree to Japan will be taken to kindly… :s

However most of these except for the T-33 will not be low BR, that is where the issue is the most!

That’s not how it works, you either need prototype components specifically designed for implementing the jet engines, or an entire new airframe that was designed for these engines from the start. The potential for conversion of one design to another does not equal a prototype, as it is still entirely an unfulfilled paper plan.

In his own words, Kiyohara wrote, “At the ‘Shinden’ Prototype plan requirements in 5th of June 1944. Air Technical Arsenal’s engine department instructed, ‘Proceed with the design taking into consideration the use of a gas turbine engine.’”

Kunitake Kiyohara transelated words “I thought the Tomoe War era was finally coming to an end. Considering the engine arrangement of the Shinden, it didn’t seem that difficult to replace it with a jet engine. I remember feeling excited that it would be something I wanted to make happen as soon as possible. In the end, this did not come to fruition, but Kyushu Aircraft also prototyped the twin-engine jet attack aircraft, the Kikka, designed by Nakajima Aircraft, and the war ended when the first unit was almost complete.”

Edit: (added this image I drew to better prove my point about how easy it would be to install the engine)

I did draw this from memory but I am 95% sure it is accurate.

I feel like this plane will only need a photo of the prototype or some official diagram from WWII, like you said if it had built prototypes there’s the tiny chance that somewhere in Japan there might be physical media relating to this airplane just like the engine parts of the Ki-201 found more than 70 years after the war ended, I know it sounds crazy but one can only hope

South Korea should never be a subtree. It’d only really fit USA, and they aren’t lacking in vehicles at all. The only relations Japan and South Korea have is mostly negative. The only time that I can think of when SK and JPN worked together was recently, with China, against American Tariffs.

It’d also further isolate North Korea from the game. Ideally we’d get a United Korean Tree, and a Turkish subtree if Turkey themselves don’t get their own tree.

and the OI Tank tracks that were reportedly found (don’t take my absolute word for it)

Yeah that even passed as suggestion in 2024!

But they never proceeded with the engine swap no? The ability to easily swap the propeller engine for a jet one, regardless of if it was an idea thought up during the war, did not manifest in any sort of prototype, which puts it below the Ki-201 in terms of likeliness to be added.

You mean the singular link we already know of or a full length of track?

Yes by the rules it is unlikely however the facts are on the table, Gaijin can with these facts make a working realistic aeroplane for the game. It is very few things that is a mystery here, infact the Kikka got in despite having unreliable engines, the Karyu can get in but it has never flown granted it being a Me-262 variant means it probably would be able to fly if completed. J7W1 to J7W2 speed increase is not that much it would probably be kinda like how it went with the Yak-9 to Yak-15, including to that the He-162 is faster probably since it is made from wood!

It seems very doubtful to me that Gaijin would be interested in adding more paper aircraft right after removing the R2Y2s, but to each their own I suppose.

Yeah but there they did not even know where the weapons and engines where suppose to go and just stole ideas from other jets aicraft 262, F2H & MiG-9 etc etc. The J7W2 is at the very least has data to back up where everything should go, gameplay wise they would be nearly same but one being a bit faster and way more noisy… (also hit boxes is probably 99% same)

The R2Y2 V1 is actually somewhat of a real design as it had been proposed during the war, same as the J7W2. Both vehicles have around the same amount of supporting evidence and progress of design and Gaijin still chose to remove the former. So while you may find the J7W2 realistic enough, the no-blueprint planning level clearly isn’t enough to be added.

My problem with the R2Y2 is that the only realistic config is the V1 and that one may or may not have the engines in the correct spot, for all we know they could have mounted the 2 of them on the top like the He-162 or two of them on the back like the american A-10 tank buster… x-x

True, but the point being that the J7W2 isn’t all too different than the R2Y2 V1, and seeing as how Gaijin is removing it for the simple reason of being paper, it’s reasonable to assume that they would not add a similar vehicle back into the tree.
