Same source has Arkansas having shells of 870 lbs while the Alaskas had shells of 940 lbs (HC) or 1140 (AP). Seems like totally new and not interchangeable shells.

I'm not sure if it's the same situation as the North Carolina, South Dakota, and Iowa class ships being able to interchange shells (maybe the Colorado class as well?)
