The US more or less kept their pre-Washington Naval Treaty battleships away from the front lines after Pearl Harbor. The Japanese, on the other hand, sent their dreadnoughts into battle, and got slaughtered accordingly.
The Battleship classes the US built after the WNT (North Carolina, South Dakota, and Iowa) were designed with much better AA systems than dreadnoughts, making them much more durable in the era of naval aviation. All of the Japanese capital ships in WWII were horribly outdated, save the aforementioned Yamato & Musashi, which sank without ever seeing a US Battleship.
Japan had no choice, the vast majority of the aging and about to be retired flotila of destroyers and other ships were at there end of service life and no retrofitting could fix
Ship maintance facilities could not even keep up with the demands of the exisiting fleet let alone keep up with new construction, essentialy Japan naval strength had peaked and many of the older ships just had to be used or shortly scrapped
Then the Japanese could not upgrade there ships with the new changing war demands such as more AAA, the Japanese never even managed to solve the problems with the exisitng triple AAA mount which would shake so much when firing that it would throw of accurate shooting. I think Japan only manage to put radar onto there main ships within the last year of the war
