Armored Cruisers of the Mark

[Ithekro]

This class would be the last Rohirrim Armored Cruiser to follow the international standards of cruisers. Armed with additional 6 inch guns in turrets and with a very long range to assist them in getting round the Horn to the Eastern Coast of New Beleriand from Rohan, these cruisers were the best Rohan could muster until 1891.

Purchased in 1904 from the Confederacy to fill the gap of the soon to be redesignated older Combat Cruisers as Dwarven Battleships, the Hill-class was rebuilt to fill in with a superior vessel until more modern Combat Cruiser could be built.
