This question is too simple. The key depends on how you deal with it. Let me quote the other stuff from upstairs first:
Nationality, armor-piercing defense, high-explosive defense structure, defense torpedo defense
Country A 2 2 2 3
Country P 1 2 2 4
Country E 4 4 4 2
Country G 3 3 3 2
First of all, let’s talk about the UK: the British roof is not only strong but also light. For the Lion 5W drainage, it is generally no problem to install it up to 5.0. The standard is 4.8. Even if it is full of resistance and is fully hit, there is still a chance to retreat. Generally, it is installed on the side. 1.2 Mainly anti-fish, but the British fish armor is not good, so I often see submarines in seconds. The British artillery is indeed the strongest. As for the non-mainstream armor scheme, it is not recommended if it does not have PK, which means less equipment. The artillery shells are less loaded with troops. Even if it is installed to 12, it doesn't make much sense. British artillery battle armor is number one, especially when it comes to 5.2 1.2 0 2.
As for the United States, although the Montana Armor is not weak, the United States is recognized as a squishy ship, and Dana is no exception. Generally, the PCV team can directly dive in seconds, but except for internal situations, the basic defense is too If it's high, you don't even need much additional defense. The American line BB is relatively brittle and if it is hit by all, there is absolutely no chance of retreat. In fact, the defensive effect is also the worst. This is because the American line BB usually does not have air defense, and this level of armor cannot withstand aircraft at all. For the non-mainstream 3R or 2R Yamato, you can consider the tank configuration - -#
Japan Although Japanese ships are brittle, the Yamato is not as brittle as the Dana. Although the Japanese are junk in their small boats, they are nothing more than torpedo armor. It's obviously better than the others. I used to use Queen Victoria to hit Yamato and hit all of them with over half health and 2 critical hits with red blood. It should be because Japanese ships are equipped with anti-aircraft, so Japanese A is mid-range.
The German line was stronger at first and then fell behind. The 44 was not brittle in the first place. In fact, it was similar to the Dana, but the tonnage was too large. The larger the tonnage, the less resistant it was to armor-piercing attacks. From a BB perspective, the gun resistance was actually Not as good as Yamato, it is still relatively strong in the early stage.
I personally think that Britain-Japan-the United States-Germany are just relative to the BB's survivability and artillery combat attributes. I can't comment on CV because my CV skills are not good.
