IOWA class

The Iowa-class battleships were not the ones with the largest guns or the greatest armor, these records are held by the gigantic Japanese Yamato class, however, it is indisputable that their design achieved such a balance that they became the best battleships in naval history. Their exceptional qualities allowed them to be modernized on several occasions and to have a career that lasted until the 1990s. After being definitively withdrawn from the reserve in 2006, the four members of this class have become impressive floating museums that allow us to continue enjoying her impressive appearance.
