Mexican NavyEdit

The Mexicana class represents the locally produced licensed version of the Espana produced by Mexico and then refurbished with oil instead of coal boilers by Spain under agreement with the shipyards in Costa Rica. These ships represent the first battleship construction done in Mexico as opposed to purchase on the wider market.
