Hello Cpt.Hissy! Towards the end of the war in the Pacific the Americans had planned to release the new Montana which was to be 5 super battleships with four turrets of three 406mm guns! Longer than the Yamato 260m against 280.57m and also more tonnage than the Japanese battleship: 65030 t against 66,040 t for the USS MONTANA and that with the same belt armor for both ships! You should also know that there are longer ships with more tonnage, eg Symphony of the Seas with 361m and a tonnage of 228,080 t !!! It's all about mass balance! 😉
