Dwarven Battleships of the Mark

[Ithekro]

The Colony of New Beleriand built a few purpose built coastal defense battleships over the years. They are named after legendary Dwarven rulers of old.

Rohan developed a different kind of Armored Cruiser in 1889 to use the 11 inch gun and 9 inch guns together. This "Combat Cruiser" was designed to be faster and have a heavier punch than the other armored cruisers of the era. However these ships paid for it my having few heavy and medium guns. However the 9 inch secondaries were placed on top of the 11 inch turret. While this seemed like a good idea at the time, it later turned out to be a problem with the ammuniton handling and over crowding of the turrets and magazines in the forward part of the ship. However the designers had made such a good impression that six of these ships were ordered. Only three were finished as designed, the fourth was rebuilt into a radically different design. The fifth and sixth were reordered as a different class in late 1890.

Combat Cruisers are named after kings of Arnor and Gondor.

Reclassifed as Dwarven Battleships in 1905.

Elendur is a one off class. The fourth ship of the Tarondor-class originally. Her "secondary" turret was removed from the design and casemate 9 inch guns were placed on the hull along with two additional 6 inch guns. The ship's range and armor was reduced to allow for the speed and firepower to remain on the previous classes hull.

Sold before being reclassified as a Dwarven Battleship in 1905.

Elendur - laid down 1890, reconstructed on the slip. (Sold to California 1904.  Lost in earthquake and fire in San Francisco in 1907.)

With the introduction of the 4.5 inch quick fire cannons, the Combat Cruiser became a better cruiser. The Rohirrim were still trying to get too much firepower into there cruisers. However, this was the last years of Rohan ordering two Armored or Combat Cruisers in a year, as the cruisers and battleships were getting too big for the economy to handle.

Reclassified as Dwarven Battleships in 1905.
