History

The Province-class Armored cruiser was the last generation of Armored Cruisers built for the Imperial Hrydonian Navy. It numbered 8 ships, with the first one being built in 1906 CE and the last one being built in 1910 CE. The Eastmarch is a typical member of the class, and usually the one considered as the ideal of the class. The last one was decommissioned in 1937 CE and scrapped after nearly 30 years of service; the class was mainly considered obsolete by then in comparison to the newest cruisers then entering service with foreign navies, as reported by the naval and military attaches of the time.

Armament

The Province class was armed with 4 254 mm main guns, 8 203 mm secondary guns, and 20 127 mm tertiary guns. Most naval historians, in view of the lack of files on why the 20 127 mm guns were required, consider them intended for use against torpedo boats or nearly anywhere the rate of fire would be more useful than the weight of fire.
