Initial take on a new Iberian carrier for 1945. Figure a sister would follow in 1946.
I'm basing it fairly closely off the previous Porto class from the mid-thirties. The main difference is the higher average freeboard, and consequently reduced deck armor. Displacement is also heavier. On paper, this looks like a bad trade-off, but I think it's a more accurate sim for a ship of this size than Porto's (with its 4.6 m freeboard aft).
There's natural temptation to spring for something larger, but this size of ship should be good for a couple of decades, and Iberia's got to be mindful of hull numbers in case it's got to curb-stomp China and Mexico at the same time.
