HMS Moria

The HMS Moria is the Flagship of the Dwarven navy and the Command ship of the Mithril Fleet. Completed in 1488, the ship has been equipped with the most experienced crew and undergone 5 years of extensive war gams, and has been approved for operational use by the High King. The Ships stands a length of approximately 3,00ft long, with a beam of 460ft, making the ship rival some defense platforms. The Moria's Size is over 3 times larger than the Massive dreadnoughts that support it. The vessel maintains hundreds of weapons for naval combat and has a personal legion of marines aboard for any potential invasions or military actions that might be necessary. The ships has the potential to command the entire Dwarven navy with room for all admirals if necessary, however never more than half are allowed aboard for strategic reasons. The Ships houses 5 Rune Reactors to power the ship accommodations, including water, food, light, waste disposal, and communication. 
Due to the Ship's immense size, many traversal mechanisms span across the ship but are reserved for officers of the navy and military. The Ship retains a large contingent of enlisted blacksmiths and others for repairs and management of the interior of the ship and the Marine Legion. Much of the Ship's lower decks allow for extra storage and comfortable housing due to the lack of need for storing food, water, fuel, and other necessities. The complexities of managing the ship require a crew of 10,000 not including the Legion. Most of the crew serves military uses and management of critical infrastructure, and emergency repairs. Such overlap helps to ensure that the Ship can endure a hypothetical siege, and even disabled is a fortress needed to be conquered. 
The moria's Armament consists of the following; 3 Titan class heavy turrets = Quintuple barrel 9 Super heavy class turrets = Quadruple Barrel 21 heavy class turrets = Triple barrel 63 medium-class turrets = Double barrel 189 small-class turrets = Single barrel 567 Volley (anti-fighter) class turrets = Quadruple barrel 1,000 anti-boarding defense mechanisms = mixed weaponry (Fire, guns, blades, etc.)
2,000 ship security personnel- trained for anti-boarding and boarding combat 6,000 legionaries- trained for beach landings using onboard longships and Boarding Combat.  30 longships in the Cargo bay to be used for sea-to-land invasion 10,000 melee weapons for potential siege and boarding. 
At the Aft of the Ship are two docking hatches for the deployment and retrieval of 30 longboats stored within a specially designated cargo hold. 
The Ship also is equipped with 2 sequester generators to conceal the ship from divination magic and allow stealth operations for indefinite periods. The Many commodity generators ensure excess space which is used to further increase defenses and allow comfort. It also allows the ship to remain in use for an excessive period of time without the need for resupply. The Ships propulsion has multiple backups, with experimental propellers for Sea combat, Artifact Forges, and Runic Engines to provide atmospheric and astral propulsion. 
Due to the moria's excessive size and outfit, it is unlikely to see combat that could truly challenge it, especially with the supporting battlegroup, which it can also support if necessary. For this reason, its crew remains relaxed and confident, while the Military seeks to use the Ship as a deterrent against advanced nations invading, and as a command structure for military operations in far-flung lands. The Ships capability to also provide vertical perspective and serve as a mobile command base in land operations has ensured an Army command hub within the Ship for potential operations. Due to this 1,000 troops of the Rangers are assigned to the ship for "Special operations". This success has also instilled in the army to provide additional funds to create sister ships for the Moria.  Each of the further 7 ships is expected to take a decade to complete within the Fireforges and be named after the holds of the Old World. The ship is currently under construction within the forges and is to be named the HMS Lonely Mountain.
