>>24587802The Yamato class had been the largest battleships ever made. Over 150 anti-aircraft guns, nine 18-inch guns (compared to the Iowa class's nine 16-inch guns), as much as over 2 feet of armor in some places, and some 70,000 tons in weight.
The ships had unfortunate ends in World War II (in the form of taking over a dozen torpedo hits and several bomb hits from turbospammed American planes when most ships would go down with a fourth or a fifth of what these ships took), but if anything that just makes the comparison stronger since the only thing that could bring Amour down at this point would be some incredibly major, powerful, or calamitous plot event. That is to say, they wouldn't be able to sink the ship subtly.
Similarly, when Yamato sank, all three of her ammunition stores detonated, which resulted in pic related. I imagine the fan reaction from amour being sunk would be quite similar.
