The North Carolina class battleship appears in both the Italian and Normandy campaigns as a fire support ship. In both times, her 9, presumably, 16 inch guns fire at shore and inland targets though it appears to do almost nothing to help.
In the Normandy campaign, you are ordered to hold your position along with St. Mare-Eglise and St. Come-du-mont. The battleship is then given orders to fire, which it does, however it does not do much at all.
Although it is a North Carolina class ship, none of the two of the class were present for the Italian or even Normandy landings as both the USS North Carolina and USS Washington were stationed at the Marianas Islands in the Pacific Theater.
