The carrier is a complete rebuild of the Minas Gerais class battleship and the second is a cruiser concept for escorting the new carriers. However, there's no guarantee that either class will be built, or rebuilt in the first instance, simply because I have no idea what my build schedule is going to be like in the 40s outside of the two capship classes.
