Adding a Japanese heavy tank named O-I ?

[Tirit]

Would the gamers of WT want to see this heavy tank ? We did lose the Maus, so i do doubt the O-I will arrive to the game. But i found it on google and found it pretty intresting. Please leave a comment ^^

Only problem I see with it is that there's no information out there on its cannon.

While it probably didn't exist I'd definitely like to see it in-game. Japan needs more tanks period.

I belive the main cannon was a 150mm, but you are right there issent much info out there...

Caliber alone doesn't really help in actual performance. As far as I'm aware, the gun wasn't even made yet, it needed a 105mm to stand in during trials

If the gun is too weak in relation to the armor, it'll be too hard to balance like the maus

It was built, there are documented tests of it albeit in an incomplete form.

So you want a worse ferdinand, I see.
200mm armor max and the thing is HUGE.

The O-I was a concept, an idea to try out, but they didnt had the time to do it.
Thy made some attempts, but they had too many problems, which are common to german heavy tanks, and thats the engine and the transmition. and the tank never had a turret
Games like WoT got it, but its mostly a troll tank, no much gameplay there

They did make it and test it, though they did so without the turret equipped. There are documents to prove it that were leaked back in 2017, but the rumoured picture and other documents of it is still held by FineMolds.

It has 150 mm thick armour, not 200 mm.

Indeed, Japan needs more tanks to be on par with larger nations*. I just don't think it needs tanks like O-I, and I don't think any tech tree needs fictional tanks. I still remember how when they added the first completely made up tank in WoT they were proudly saying that they've created it from scratch with their knowledge of how tanks are made. I also remember how disgusted I was at the notion.

Nevertheless, Gaijin said that they do (of course) remain open to implementing that (and any other) tank should the documentations with enough data resurface somehow. It won't be the first time either, that's how we have Ho-Ri. That doesn't change the fact that it's most likely a horrible fit for this game.

*The reality of the situation is that they'll probably never be on par when it comes to ground vehicles. It can't be helped, not without populating their tech tree with clones, which is not the answer.

The problem with the O-I is that, because of it's gun, and because of it's armour it'll end up at mostly the same BR as the Maus, or even worse, depending on how strong it is. We know how the Maus is.

And while I agree that Japan, among other nations, needs more vehicles, the problem with those is that they are mostly prototypes. And, as many prototype vehicles show us, they may be extremely bad, or extremely good.

And even if Gaijin decides to add only the O-I, who tells us that it won't be a tank alone in the middle of the tree? Or even worse, a premium. Or even worse, an exclusive tank from a "Battlefield Engineer" kind of event. Or even worse, a season exclusive from World War mode or a sh*tty tournament. I think it would be positive to investigate Japanese tanks to be able to propose an entire line of tanks with the sole purpose of justifiying the existence of the O-I in the tech tree.

You bring out alot of great points Billy :)

I could bring a lot more, like how Gaijin is focused mainly, specially on tanks, on modern vehicles or how would the O-I work with the little info we have about it. While tanks with little to no information are in the game, like the King Tiger 10.5cm, at the very least this tank had only one thing to work out and it was the cannon and the turret, and those could be easily imported from other tanks.
The O-I is a completely different beast, we have at the very least the 105mm gun from the Ho-Ri to work with but, what if it had an even bigger gun, or a new type of 105?
If you were to add a line exclusively with Japanese heavy tanks you could work with this diferences and try to make a "World of Tanks like" line for these vehicles.

But there's a problem if we add this vehicle. While prototypes are nothing new to the game, Gaijin has been "special" in how they add them. Meaning that prototypes are used more to fill spots within tech trees to offer a way to compete in certain times where the nation had no effective vehicles. Japan is able to compete without heavy tanks with it's current tree, and what many people could see as a "blatant adition of prototypes into the game", it would excuse the addition of more and more ludicrous prototypes into the game, and thus the game would become more "World of Tanks like".

Would it be fun to add the O-I? Absolubtely but, it's needed? Not really. Would it create an excuse to add a lot of grind filler into the game? Absolubtely yes.

I doubt it would go to 7.7, the armour is far worse than the Maus and is more comparable to the Churchill Mark VIII being only 2 mm thinner than that. That is not mentioning the fact it is much wider than the Maus and is just as tall and slightly longer. The gun would also be in no way comparable to the Maus as it is the low-velocity Type 96 howitzer. From what I can tell it would be comparable to the KV-2's howitzer as it has both high-explosive and armour-piercing/anti-concrete shells.

It wouldn't end up at the same BR at the Maus but much lower.

Edit: It would also get only 7.33~ hp/t.

This is from Wikipedia, so even I take it with a grain of salt. First of all there are two Designs for the O-I, one is the 100 ton from 1940, and then there's the 1943 one that weights at 120 tons. From what it says here it has a maximum of 200mm of armour, meaning that at the very least for armour it would be a tier 5 tank. The main armament would be a Type 92 105mm L45, so the gun is able to be used in 7.0 and upwards, because the Ho-Ri production if I remember correctly uses the same gun. It also has 3 7.7mm Type 97's and a Type 1 47mm gun as a secondary. And from what the diagram that's used in Wikipedia shows, it wouldn't be easy to kill.

From what I can see, which is completely open to speculation, it would be very slow but, very deadly if implemented in certain ways and, it would probably be an 8.0 tank just because of it's armour alone.

That's false information. The only legitimate documents of the O-I are held by FineMold, luckily some of those were leaked back in 2017 (or 2016, can't remember). The blueprint showed the O-I equipped with a 150 mm howitzer and there is no record of actual plans to equip it with a 105 mm except for unsupported assertions by engineers who apparently worked on the project. The secondary armament is equally wrong, the armaments were this:

• One 150 mm Type 96 howitzer in the main turret
  
• Two 47 mm Type 1 cannons each in separate turrets on the front of the hull
  
• Two 7.7 mm Type 97 tank machine guns in a dual turret atop the transmission in the rear

This is supported by Mai_Waffentrager as you can see in the suggestion[forum.warthunder.com] for it. In that same suggestion you can also find the blueprints I'm talking about.

Edit: The only design that existed was the 150 ton design, the 120 ton never did, and it only had 150 mm of armour which was to be composed of two 75 mm plates.

That's actually pretty good but, even then I don't see it being lower than 7.0.
