Personally I hope they find Sekrit documents that enable them to introduce a whole heavy line of OI versions. 

I'm sure there currently only 3 O-I variants I know about (from the thread and other places) one without the main turret, one with the turret and the last one with the additional bolt on armour, Mai has pretty much seen all the seckrit documents as far as I know.

As long as this tank get's an actually good gun, I'm all for it. Hell it got further into production then Maus tank and that's in game.. Hey even the E100 only had an incomplete hull completed. I really don't see a problem with this.. 

Lets all remember that the Germans also has the Panther 2 (never created past paper) and the Tiger 2 105 (the same). And we know how they all go in top tier matches against ATGM's, this thing should be 7.3 BR if it has a good gun or 6.7 if it gets the crappy gun.

A couple of things.

1. It got to the same production step as the Maus(fully functional prototype performing tests)
2. Panther 2 and Tiger B 105 had their hulls made, so they are at least 50% iron.
3. Type95 APHE shell,  540 m/s,average penetration of 125mm at a range of 230 meters (standard round)

[Nobidexx 367]

It should be 5.7 or 6.0, it could only go higher if it had some very good HEAT shells like the ISU-152 has for example.

 

It's basically a slower KV-2 (very similar gun), which is a 4.3 tank, but with much more armor and survivability. 5.7 would be fine because its gun is terrible at this BR but the armor is still good while not invincible (almost all tanks at this BR can penetrate it at least through weakspots). I guess something like 6.0 AB and 5.7 AB would make the most sense since tanks like that are much better in AB than RB.

 

Edit: I'm not sure if it's supposed to use the same type 95 APHE shell as the Ho-Ro, but if it is it's even worse than the KV-2's APHE. In-game it's got a bit less pen than Mai said, a lot less filler than the KV-2's APHE shell and terrible muzzle velocity (290 m/s). I wouldn't be surprised if some of its stats were still placeholder though.

if this tank was added it would be beast mode, but knowing war thunder it would be a premium vehicle http://www.tanks-encyclopedia.com/ww2/japan/O-I.php

[Asakaze 992]

I dont think it would be that great... its more like a heavier armored Kv-2.
Imo it wont be premium since there would be a hole in the already sparse heavy line

One more thing, it wont look like the one in the illustration you posted. It'll be much more boxy~

*drools all over keyboard*

 

yesssssssssssssss. with or without the 152mm top turret, i see this thing as being like a tier 3 T-35. great armament, decent-ish armor (flanking this thing is a no-brainer) but good god Hellen Keller couldn't miss this thing from a mile away wielding a WWI Kolibri pistol (look it up) with an arm tied behind her back... while facing the wrong way.

 

on a related note, what the size of the other 3 turrets?

Do you mean the caliber of the guns in the secondary turrets or the size of the turrets themselves?

 

The turrets have a diameter of around 150cm and are fitted with two 47mm guns, the same as the Chi-Ha Kai, and one MG, probaply a  Type 97 7.7mm MG.

considering the battle rating about 5.7.....
decentish armor? 150mm front is more than decent. the angled front plate has more effective armor than a king tiger, the whole tank can be perfectly well angled.

that's just the front plate. and while yeah i have no doubt it can still be angled, the whole tank is a giant brick. getting side shots won't be all that hard. with that beast it's more about shooting blindly into a cavern and hoping to kill a crewman or an ammo rack- which may not guarantee a kill itself since ammo rack explosions won't be instakills anymore.

i meant the guns. but thanks for both anyways!

You can't really angle the tank, because the sides are only 35mm (it's got additional 35mm side skirts, but if you angle it something like 30 degrees you can shoot the tracks and hit the weak side armor behind it without having to go through the side skirts).

 

Also, ammo racks are instakills 100% of the time. The main's gun ammo will probably be stored deep below the turret, but the ammo for the 47mm turrets might be easier to reach (it might be in the turret itself like for the T-35).

 No bruh. Panther II had it's hull completed. The Schmalturm was build and at least 1 still survives in Bovington. The 88 gun Panther II has saw service on other vehicles (Tiger II for example) so no it's not just paper. Similar story with Tiger 105

you can angle the tank. In total it has 150mm side armor, check the sensha article about the armor layout of that tank.
tracks can weaken the shells penetration too btw. I think it has a modifier of 0,7. so assuming the tracks might be 30mm thick there would be stil 21mm of armor + the other walls between the shells and the inside of the tank

you are right ammo racks are 100% kills. I dont understand why this is just "O-I regarded but keep in mind that you have to penetrate 150mm minimum before you can even think about reaching any ammo. even the small turrets have 150mm armor.

Where did you see that its side armor was supposed to be 150mm? That's what I saw:

 

 

The side armor on the hull superstructure was 70 millimeters thick. the base having standard thickness of 35mm, supported by an additional 35mm plate bolted on

 

 

It kinda makes sense anyway, it'd probably be as heavy as the Maus if it had 150mm side armor all around (still less armor than the maus, but the tank is much bigger and has extra turrets and guns).

 

If you add the tracks and angle the tank at 30 degrees it's still equivalent to 56mm at 60 degrees. That's easy to penetrate, and while it may not reach the ammo (it depends on whether the 20mm internal walls are modeled, sometimes internal armor isn't), it'll still kill most of the crew at the front of the tank (at least 4, maybe 6). And solid shots / sabot might be able to go through the internal wall as well and reach the ammo.

 

This having been said, I do agree the armor will be very good for its BR, though it has to be like this given how slow it is and how lackluster its gun will be for its BR (it's in the same situation as the churchill mk VII imo).

aye, it would be dumb if there was nothing which can penetrate it, thats why it wont end up at 6.3

here the sidearmor : The O-I was designed with 150mm of total armour thickness in both the front and rear of the vehicle. However, the production of the tank proved difficult to manufacture a 150mm plate, so to counter this crossroad, Mitsubishi split the plate into two separate slabs of 75mm armour thickness. The second 75mm plate would be bolted and sealed onto the existed plate on the vehicle to provide the expected over all thickness of the tank. The side armor on the hull superstructure was 70 millimeters thick. the base having standard thickness of 35mm, supported by an additional 35mm plate bolted on. There were eight wheel-supporting beams located on both sides of the suspension area which added an additional 40 millimeters of armor to specific locations on the side of the O-I. On the lwoer half of the side, a measurement of 110mm of armour thickness is present. 40 ladder pieces were placed around the tank to provide crew with the ability to climb onto of the vehicle with ease.

ahhh

 

panther II's turret would have never been able to handle a 88mm in there mate

[Nobidexx 367]

At 5.7 everything can already frontally penetrate it except the KV-220. At 6.3 even more so.

 

The overlapped 75mm plates mentioned in the quote above only apply to the front and rear of the vehicles, not to its sides.

It's got APCR, unlike the KV-220.

 

There's a 150mm flat section below the main turret, which leads directly into the turret crew and maybe the ammo. It's definitely the main weakspot.

The upper hull area has no crew behind it unless you consider the turret ring crew, protected by an  internal armour plate.

Go away with such a stupid and hideous tournament. Go away.

I just want it to be in the techtree, not premium, not tournament or event.
