Yamato standing in its end would dwarf most buildings, shes just shirt of skyscraper lengt
You know in real life it took six aircraft carriers in world War II to take out the yamato. Today the USA has 12 supercarriers which are thousands of times more powerful than the world War II ones .So if I had to say I would say she's pretty defeatable though the only issue is that it's going to take time for the carriers to arrive even if one is enough depending on the location it could take days but with the advancement of ballistic missiles I give her 2 hours before she's completely annihilated
