And the ultimate fate of the Yamato-class battleships. Astrodragon hinted that they would meet a slightly different end than OTL.
Well, I can't see a battleship-to-battleship duel. Halsey had every chance to let his battle force to charge in and take out the Yamato OTL.
The battle commander asked the air commander "Do you want to take 'em or shall I take him?" "I'll take him." For the possible loss of at most some 30-40 attack aircraft you're sinking a superbattleship.
But using the American battleline would mean risking one of those 18.1 " shells punching through the armor of a WWI battleship (or WWII if they are in position to engage), leaving the possibility of a Hood/Arizona level of a catastrophic detonation of the magazines, killing over a thousand men in an instant!
And the Yamato-class was faster than any US old BB and just as fast as any US WWII battleship other than the Iowa-class. Mind, I doubt VERY much a Yamato attacking a US task force would still be capable of full speed by the time she could actually engage the US battleline.
