What is the standard of naval armor

https://community.gaijin.net/issues/p/warthunder/i/hv0uLxn7Mn2X
Armor plates made of the same material have different standards on different ships. For example, “HT steel” was considered an important component of protection on the Hiei and Mutsu in 1922, covering various hulls. However, on the Kongo and Nagato,the same class, they were all ignored. When you submit an error report, the administrator will reply to you like this:


So, why can the same steel, with a thickness of hundreds of millimeters, be completely ignored on some ships as not providing any protection, while on other ships it can provide proper protection? Does gaijin really have a unified standard for this? At the same time, why can hundreds of millimeters of steel be ignored and not considered a bug when even the coal storage on some battleships was considered part of the protection?

As I mentioned in this post, gaijin has no unified standard for whether to count as armor or not. It all depends on their own ideas. If they want, 16mm DS steel and class B structural steel can both be counted as armor, while 76mm or even thicker HT steel can also be considered as scrap iron that does not provide protection and only increases tonnage, as long as they do not want to.

If there is no unified standard for even the most basic protective armor, players will have no way of predicting how their ships will perform. Is it a fraudulent act to sale pre-order ships in this situation?

It provides protection as all hull, decks or bulkheads components.

it’s not like what u think in the game. You can compare the deck protection of hiei and kongo. hiei with multi-layer deck HT steel armor modeling has a normal armor equivalent thickness, while kongo only has a 25mm hull and nothing else. The same goes for Nagato. In Dev Server, due to the complete lack of horizontal armor modeling for the power compartment, a 140mm SAP can easily penetrate from the chimney all the way to its power compartment and destroy the boiler. However, on Mutsu with HT armor modeling, such an incident is impossible.

In the game, it appears that the Japanese Navy removed all of its underwater and horizontal protection after the Battle of Jutland, while other countries’ navies were strengthening these two directions at the same time, which is clearly not historical.
