This originally was a coastal defense gun on the American east coast.I think the bore diameter is 16".Imagine three of these side by side and you have an Iowa class turret.Let me see if I can come up with some more info for you.
... and remember that the IJN Yamato and Musashi each had 3 triple gun turrets with 18.1" guns - largest guns ever afloat.
army gun this gun was an army design that was never put into production. perhaps the most powerful 16" gun ever built. when the washington treaty went into effect there was a large number of naval guns surplused by cancelled ships. they were not quite as powerful but would do the job so they were wsed instead.
Hey you gotta love IOWA hehehehehe but you tink it would fire a massive corn stalk or something of that matter
LOL think of the long reload time u need a machine to do it pplz jsut arent strong enought to lift something that biug un;les.........
