Which is better, the Japanese battleship Yamato or the American battleship Iowa?

Of course, Iowa is even better. Otherwise, why are hundreds of millions of modern modifications of each ship used in the Gulf War? First of all, the Iowa class was developed as a fast battleship, which was faster than some destroyers at that time, and the Yamato class was too slow! Secondly, the gun-making technology in the United States was much more advanced than that in Japan at that time. The rate of fire of the Iowa MK7 is much faster, almost twice as fast and more accurate. That is to say, if the two ships are antagonistic, more shells will land on the Yamato at the same time. Iowa was already aided by radar, and Yamato was completely blind in bad weather. Daiwa adopted key armor protection, thus reducing the number of watertight compartments. What armor can resist torpedo bombing, so the watertight cabin is king! However, the waterproof and anti-sinking performance of Daiwa is not as strong as that of Nagato. If you want to achieve the anti-sinking performance of Nagato, Yamato's waterproof cabin should be 40% less!
