For classification, this is a "transitional" ship from "classical" sea-capable monitors like "Dictator" to ocean ironclads like "Devastation". The ship has a armoured "parapet" in the central part, covering the base of the Ericcsonian turret and raising the location of guns. In the bow - unarmored superstructure, to improve sea-capability.
The ship is about 5500 tonnes, and armed with 2 280-mm rifle breech loaders.
