Japan's phantom multi-turret heavy tank Oi vehicle

So just to confirm this is an exact model of what the tank would’ve looked like?

My concern is how many documents we actually have that can provide the necessary information to model the vehicle in-game accurately. Since the documents are being witheld by FineMolds

the lack of photos of Japan’s special tanks is due to several factors
1.they were secret projects
2. At the time of field tests, it was incomplete because it did not have a main tower
3.Japan lost the war so existing photos were destroyed
4. the hull was scrapped before the surrender, so the Americans couldn’t take a photo of it

this model is exactly according to the company’s plans. They write about it in the manual






sorry for the poor quality of the photos

a good example with photos of Japanese special tanks is the Ka-Ha electric tank, which was also a secret project and its existence is confirmed by only one photo

Wasn’t this an April Fools joke?

The Japanese also write about it, so either it is a real vehicle or a very good joke

Not sure I get the comparison. TOG was built and tested with dozens of variations.

The only major historical issue with the TOG in-game is the “GWP” modification, which is optional, remove that and it’s pretty much the TOG II* that can still be seen in the Tank Museum today.

"Also, copy/paste from MaiWaffentrager:

Hello everyone. This photograph has been around on the Internet for nearly 12 years now. Until recent years it has been most associated with the Japanese O-I superheavy tank. However as of late it has been confirmed this photograph was taken around Kotoh Fortress in Manchuria, 1945. After the O-I project was ended in 1943, Japan continued another project with an improvised heavy design. Little information is known however by the end of the war the tank had been disassembled and the turret was used as a stationary mount for the fortress protecting the mainland. Soviet troops after taking the fort took notes and blasted the remains of the tank along with the other bunkers and heavy guns. Technically as this is the second Super heavy tank Japan designed, it would have been labeled O-Ro (Big Second). As standard heavies occupied the name Ju."

I have a feeling this image is fake. Here’s the exact same image but without the soldiers. Looks like they were added in. If that image is fake, what’s not to say this image isn’t fake either?

"2020 post by MaiWaffentrager confirmed that this was a coastal artillery installation part of the Kotou fort, thus a naval gun. to quote:

The photograph is taken at the Japanese fortress of Koto on the Manchurian coastline. Soviet forces captured the fortress containing one of the last remaining Japanese holdouts in the region. Various coastal defense turrets were positioned at Koto fortress for the invasion. These turrets consisted of thinly armoured, housed naval batteries alongside the Manchurian coastline. While the turret photographed is likely to have been real, it is also likely that it belonged to no such tank project. The Imperial Japanese army would not have used Japanese naval guns in their vehicles. Due to standards and regulations, only army equipment was permitted to be used within the army. “

Isn’t Mai the one who fabricated documents to get vehicles added into the game?

Since the sloping on the armor is minimal, anything like the US 90mm and stronger will just LOLpen it. Also, you can’t angle it, because (to my knowledge) the armor behind the tracks are just 35mm.
If they implement it, it would be around 5.7-6.3, where it would regularly meet things, like IS-2s.

here is a cross-section of the armor of an OI tank

I don’t see a problem with the armor of the OI tank because probably like almost every super heavy tank it will be a premium vehicle which is almost always underpriced.additionally, its history as an OI tank begins only on the test ground, and previously it was known as the MI-TO tank and did not have these additional 75mm armor plates installed until the end of its existence.in this case they can add the MI-TO tank with 75mm armor to the tech tree and the OI tank as premium with 150mm armor

You might be confusing the O-I with the completely unrelated, and most likely fictional, Type 4.

Sure, in the flat areas that would be possible, however this is not so easy. The lower frontal hull is highly angled, while the upper frontal hull is also at a slight angle, and more importantly largely hidden behind the two frontal secondary turrets. The main turret also offers angled armor, assuming the turret is pointed at the enemy.

It is, however there is an additional 35mm of armor in front of the tracks, bringing it up to 70mm. That isn’t much less than a Tiger I and the significan increase in frontal armor more than makes up for that.

I don’t think it’ll end up higher than 6.0, where it would share a BR with the Tiger I (that is already well armored), but with even higher protection.

Sure, it could face cannons that can destroy it, but that is supposed happen. Nobody wants invincible enemies. And most would still need to flank it to get a chance.

Yes.

I was responding to O_Ho. They posted the picture.

I wasn’t referring to O-I at all.

But from the front, the 35mm side would be exposed.

The upper plate is ~15 deg. So, in WT, using the Tiger 2 hull (150mm) at that angle, we get:


The turret (in the middle) is at 32 deg, giving the protection of (and APCR goes through it with the US 90mm):

Against common, stronger guns, like the soviet 100/122mm guns, the long 88mm, the 128mm (on the Emil), they will pen it from a km:



The Emil will pen it from almost 2km!

Nope. The issue with minor nations, especially with Japan, is that many of their vehicles are way overtiered.
Do you think, that the Chi-Nu and the Pz 4 F2 are equivivalent?
Or even the Chi-To being at 4.7, while Panzer 4 H/J are 4.0, while the german tanks are even just better.

Since I still believe it is best suited for a BR similar to that of a Tiger I, I don’t believe these would be such a big issue. The strongest guns of the BR range, often found on tank destroyers and/or limited by long reloads would be necessary to destroy it frontally. Otherwise careful aim for specific areas or flanking would be necessary.

Compared to a Tiger I the O-I provieds much greater frontal protection, a hard hitting main gun, secondary guns that can come in handy against lighter oponents and a higher crew count. Meanwhile the tradeoff for those benefits would be slightly lower side armor, a lower velocity and significantly lower mobility. Additionally the track weakpoint appears when angled, allowing experienced players a way to take out the angled O-I in many situations with some weaker guns.

With that I’d say sharing a BR with the Tiger I would seem fair. I’d propose a BR of 5.7, but depending on performance that might be adjusted later.

While this is an issue, simply refusing a vehicle won’t help.

I’d also argue that vehicles like the Chi-To are exactly where they belong, and that is is outliers like the Panzer 4 H that need to be moved up. Generally the game seems to compressed when looking at the vehicles performance increase throughout major nations tech trees, while trees like Japan seem to have more gradual, natural seeming progression. But I understand that this doesn’t make the situation any better.

Generally, I’d say the O-I at ~5.7 would be a very useful tank to have that, while not invincible, could use its armor quite effectively. And even beyond armor itself the high crew and additional cannons will likely be of good use in what would otherwise be problematic situations for the average tank at the BR.

The Ho-Ri prototype is 6.7 (IIRC), and it has worse armor, and a gon the requires aiming (as opposed to a derp gun), so i can easily see them putting it in at 6.3 or higher.

While it would be great at 6.0, or 5.7, sadly i don’t think it will be there.
Also, that BR range sees nothing but constant uptiers, so you would not really use the armor, since everything would just piss right through it.

While it’s not the lowest velocity 150mm, it’s should still be quite lackluster at range. At least the APHE round shouldn’t detonate to foliage, fences and tracks like HE, but at 6.0 and above 130mm penetration isn’t going to be helpful, so you’ll need to lob it top or bottom.

There aren’t really good tanks to compare it to. TOG, Brummbär and T30 perhaps? I think 5.7-6.3.
