Yamato, Musashi, Shinawatra, Bismarck and Iowa are most interested.

Theoretically, the thicker the armor, the larger the caliber of the artillery and the stronger the warship.

In ideal weather conditions, the strength is equivalent to one-on-one combat, and no battleship can pick Yamato and Musashi (Yamato and Musashi are sister ships of the same class, with basically the same firepower and armor, just like the four sister ships Iowa, New Jersey, Missouri and Wisconsin).

If it is a midnight battle, Iowa is the strongest, and the radar guides the main gun bombardment. Yamato can't accurately hit Iowa in a long-range night battle (the radar factor is very important in the night battle of World War II, and the Japanese fleet radar can be ignored, just like nothing).

The battleship Sinava was not in service at all, but it was changed into an aircraft carrier in the middle of construction, which also set a record-the aircraft carrier with the thickest armor. Unfortunately, the first voyage was hung up by an American submarine.

Bismarck is not a qualified warship at all. He can only be counted as battle cruiser. In terms of armored artillery, he can't compete with Yamato, and in terms of radar night fighting, he can't compete with Iowa. Bismarck's specialty is attacking merchant ships at sea.

The conclusion is that each has its own advantages, and no one is the strongest, because the use mode of these four battleships and the guiding ideology of the national strength/naval strategy of the producing country determine that these four battleships are biased, not the strongest, but the most suitable for the actual needs of the producing country.

Yamato and Musashi-the last pure battleships in the world.

The thickest armored aircraft carrier in the world.

Bismarck-Nazi Germany's combat cruiser.

Iowa-the most versatile, the strongest comprehensive combat effectiveness, the strongest air defense capability, the best cooperation with aircraft carriers, the highest honor, and the service time is rare in naval history. It is a perfect battleship, which has crossed the two war forms of bombing aircraft carriers by World War II battleships in the 1940s-shelling North Vietnam positions in the 1960s and 1970s-and launching Tomahawk cruise missiles at Iraq in the 1990s.

Unfortunately, it is also the last class battleship in the world. Although retired, it still has a place in modern wars, especially those against small countries.

If I had a choice, I would like Iowa.
