Now that we're talking about the Spanish, how about the next article being about their older brother, Portugal? Once a huge naval power that ruled the Indian Ocean and defeated the Ottoman empire in a naval war. I feel the NRP Afonso de Albuquerque could be a cool Tier II-III premium ship (even though it might be difficult to balance "Avisos" in the game).
Edit: The NRP Dão could be a Tier VI premium destroyer. Afonso de Albuquerque and Dão have a close history, as both rebelled against Salazar's pro-Franco regime and tried to flee Lisbon and fight for the Spanish Republic. Both were shot at and grounded by coastal batteries at the mouth of the Tagus river.
