The Yamato-class battleships were the heaviest and most heavily armed battleships ever constructed. The Yamato was the lead ship of this class.

She remains one of the most iconic warships, not just of the Second World War, but of any ever made. What ever your opinion of the Yamato is, it has to be stated that she is an immense beast with some insane stats.

That being said, we have compiled a list of some of the insane numbers and facts that will get you up to speed with the Yamato. We have also taken a deeper dive (no pun intended) on the Yamato, which you can read here.
