General Japanese Naval Forces Discussion HQ

You’re absolutely right, and I appreciate your point. Rather than roughly measuring values from drawings, it is certainly best to reference specific figures from published sources whenever possible.

Based on two books I consulted, I believe the thickness of the sloped armor near the No. 2 turret is 320 mm. Would this be considered an acceptable claim and source from the perspective of the Technical Moderator Team?

The angle of Yamato’s sloped armor is incorrect.

I also have a question. I reported that the angle of the 230 mm armor on the side of the Yamato is 77°, meaning it is mounted at an angle of 13°, but the manager said that the developers had previously rejected a report with the same content. (The manager responded to me politely, which I appreciated.) I think it is beyond doubt that the angle should be 83°, or 7°.
I believe the angle of the side of the second turret is 82° or 81°, but even so, the overall slope is too steep. Could it be that the 7° slope is only in one section, which I am unaware of? Or is it because the developers are expecting to receive official drawings from DMM, so the report is unnecessary? I would like to hear your opinions.

13°!?



everywhere(except No.2 turret...)


I just figured out how to use the document storage feature for the first time. Sorry for being hard to read before.

I also found a distribution diagram of horizontal armor that I had never seen before in Mr. Janus’s drawings. I seem to have poor spatial awareness, as I cannot imagine what shape it would take.

230mm

This diagram is either wrong, or it proves Gaijin’s implementation is actually correct. You don’t need good sense of space, but only elementary trigonometry:


We already know flat Q is higher than flat P, if X1 = X2, the inclination angle of the slope over X2 must be greater than the one over X1

If you want the slope angle over X2 to be the same as the one over X1, in this case 7°, X2 must be much greater than X1, i.e. the flat Q must be narrower than flat P

I’m sorry. I realized my serious oversight. The sloping armor on the side part of the No. 2 turret of the Yamato was modeled with a large area! My apologies… However, it still has a larger angle than the rest of the body, and this is made more serious by the excessive tilt angle of 13°.

Sorry...It's wide.


I hope that most of the 230mm armor on the live server will be corrected to a 7° angle…!

The distance between the second turret and the 155mm turret has been strengthened from 200mm to 230mm, meaning that the front and back measures have been taken against undulations, so why not deal with the left and right sides? This is a consideration without a point.
The truth without speculation is that “the slope is 7° and the vital part is a common defensive standard.”

So not only do i have to research all tier 5 and 6 ships i also lose the top rank bonus?

lmao

Yup… And even worse, Yamato is extremely easy to kill. I’ve got Gneisenau and killed numerous Yamatos already, in one battle, 3 in short succession of eachother, all because of a weakspot discussed here earlier, just seems unrealistic and unfair

It appears that this auxiliary ammo storage midship and above the waterline results in a OHK in the few battles I’ve had. There’s also no way of reducing the amount you take.

True, that seems to set it off quite often

Really only reason to get Yamato is for historical reasons/ fan of IJN naval ships/ or simply to finish the tree other wise its the worst of the new BBs and not really sure what gaijin could do to make it a bit more playable besides just dying in one shot every time.

tbf, this was known since the first dev server

How much ammo should one load on Yamato Mutsu and Amagi?

I wrote a report, but it doesn’t seem to be a bug. I thought my report might be lacking information, but it’s “not a bug”…report

A good read regarding the Yamato-class, from former IJN sailors. This article was from 1953, so there may be some errors.

Exactly what I’m doing… Very disapointed and hoping for future changes…

Because the slope between no.2 turret and the 155mm turret is about 15deg inclined according to one of the official drawings. Geometrically it is impossible for the side slopes to have 7deg angle in this scenario. According to my calculations earlier, the slope behind no.2 turret must be 7deg or less to allow side slopes to stay as 7deg, but this contradicts the official drawings.

This is pure math problem, unless you can prove official drawings being wrong for the slope behind turret no.2, or you have to admit that the slope at sides can’t be 7deg.

Yes, that’s right. What I don’t understand is which books the developers used as references when modeling the Yamato’s armor. The official blueprints for the Yamato class have mostly been lost, with the exception of some work records. Most of the blueprints currently in use are based on those reconstructed after the war by engineers who were involved in the ship’s construction, with various people adding their own interpretations. Therefore, I don’t think the blueprints the developers are using are perfect. I don’t think they are correct, but I can’t prove that they are incorrect, which is frustrating. In the end, no one truly knows the true appearance of the Yamato…

Do you have citations from Japanese sources discussing about the origin of the drawings and plans that we have access to nowadays? For example, the US “captured” Japanese ship plans and data recently digitalised on NDL
