I was thinking such a fictional sitiuation in which the 2 Iowas that could be were recomissioned and sent to guard an aircraft carrier maybe?
Anyway I was also thinking it could be manned... so like 1 person per turret and a person using the tomahawks, and if possible for the ship to move a captain using it.
Even if the ship was Static the guns could fire like artillery strikes on postions, it could also fit 1 helicopter on the back of the ship so men could spawn on it as well as the aircraft carrier? Also if it is static i think it should be destroyable after maybe be hit by 3 tank shells in the front of the ship because of the curved hull, 2 in the middle, and 1 in the back because of the weak engine room or the 1 in the back could simply disable it and same with middle?
Here's a few pics of the Iowas in action
