The first true class of battleships commissoned by the WAC goverment. The design is a logical outgroath of the Beaver Republics but includes several revolutionary features. It is the first ship designed that uses a turret on barbette. The guns are upgraded to 4 13" 35 caliber breach-loaders. The primary purpose of the class is to replace the Beaver Republic class ironclads as the main ships of the line for the WAC Navy. They are part of the 1885-1900 naval modernization and expantion program.
