In December 1941, the same month of the infamous Pearl Harbor attack in real history, the biggest and the most powerful battleship in the world, the IMS Yamato, was secretly commissioned. So secretly, in fact, that most of the people in Japan didn't even know of its existence until after World War II, when it no longer existed! The Yamato was designated as "Special Battleship Number 1" for most of those who actually got to see it during wartime. Only the crew and other special people knew its real name, taken from the old name for Japan and its people in the current province. The Yamato-Damashii, or "Yamato Spirit," is the cause the Japanese used to fight a desperate war; a war that they feared might end the Japanese as a race. With this conviction, the Kamikaze forces threw everything they had against the invading military, including the battleship itself. But in this altered war, the Yamato and her sister ships will fight an even more deadly game, because the United States was unable to prepare their atomic bombs against Hiroshima and Nagasaki.
