Thank you for your interest about my late topics.
Following my research and the previous discussion about IOWA against YAMATO in the begining of the year, I would just say a little about it.
It' a fact that the IOWA were not conceived for a reponse against the YAMATO class, but were just new design of a new battleship class, called often the fast battleship capable of following the new generation of carriers.
At the time they were conceived, the YAMATO were unknow in the rest of the world.
Even in US nobody had knew that these battleship were armed with 460mm guns until the end of the war.
The only thing that was beleived is the fact that the japanese had made new design of big ship after they left the 1936 treaty.
If you compare the two ship class they were extremely well conceived regardless the poor control gun fire of the YAMATO ( and the lack of a good radar control system).
I think, when you read the litterature about the ballistic of the 460 mm, no US ship even the IOWA were a good place when you were the target of these guns and its related that the spread at 40.000 yard of a salvo was under 200 meter, so nine 460mm shell could fall in the same time on the hull of a IOWA.
The MONTANA was may be the answer of the YAMATO power, but the successor of the YAMATO class ( only at the stage of the evaluation drawing circa 1940) was featured to be armed with three or four turrets of two 508mm guns in a hull well over 100.000 tons.
Its reported that a prototype of these gun was found by the US in the end of the war.
There is a good anticipation of the kind of battle these ships could have done at the following links:

The web adress of the Kure museum in Japan with
a 1/10 model of the YAMATO and also a replica of 190meter made for a movie of the foward part of the ship in .....1/1scale, check the home page.
