The Ultimate Battleship Battle: Japan’s Yamato vs. America’s Iowa

byMichael Peck

It would have been the ultimate duel of dreadnoughts. In one corner, Japan’s Yamato, weighing in at 65,000 tons, the biggest battleship in history. In the other corner, Iowa, at 45,000 tons the pride of America’s World War II battleship fleet. In reality, the two ships never met in battle. But what if they had, in a cataclysmic clash of seagoing titans?

One researcher can offer an answer, or at least a very educated guess. Jon Parshall, historian and author of the superb Shattered Sword: The Untold Story of the Battle of Midway has pitted the top battleships of various nations against each other at Combinedfleet.com, the go-to site for information on the Imperial Japanese Navy.

Among the battleships he compares are Yamato and Iowa, based on five criteria: guns, armor, underwater protection, fire control and “tactical factors” such as speed and damage control.
