The above point being that though the Atago did not fire her main guns in the battle of Leyte Gulf she was part of the center force and was sunk in the battle Certainly the sailors that died there or that were pulled out of the sea would feel they had participated Super battle ships There is some back and forth on the wording of the lead What is the contention Certainly the Yamato class were the largest in terms of tonnage but not the longest as that goes to the Iowa class I believe Is large tied to the ships length I believe that is the convention as that was how liners that competed for the distinction in the inter war years were described the largest liner being considered the one with greatest length As to powerful vs powerfully armed I would prefer wording them the most powerfully armed but the heaviest gunned might be the best descriptor Most powerful would that be determined on the basis of the caliber of her main armament the metal weight of her broadside or the rate of weight put out over a period of time It seems to me these terms are discussed somewhere and we should find a key and come to a consensus
