About the ships:
As you can see the left image is the "Atago" in the "Takao" class. The right one is the "Maya" from the same class. Yet the "Maya" has one turret less. So would there just be 1 model for the "Takao" class or would there be a more specific model for the Maya since it has 1 turret less?
Edit:
The turrets are not the only difference but i used those as an illustration of the situation.
