Pearl class Star Dreadnought

The Pearl class is a class of Dreadnoughts of the Interdimensional Navy. It's one of the strongest starships avaliable due to their massive Gluon cannon.

History
The Alliance High Command requested a fast and powerful ship capable of housing a new experimental weapon. The first proposals appeared on 2033 of a medium sized but decently armored vessel capable of housing the massive gun. On mid 2034 the Gründehr Inc. came with the first design. It was called XM-001, and it measured about 600 meters and weightened almost 150.000 tons but, the design had a drawback: When the Gluon cannon was equipped, no other weapon could fit on the ship, even if was simple 75 mm cannons. After that, the XM-001 project was archived. In 2036, the Federation forces initiated a siege of Terra 22, isolating the capital, Inkopolis, from any external contact. They decided to take an aging model, the Beaver class Battleship, as the selected to house the gun. In only 3 months, 45 Beaver class were modified and the version carrying the Gluon cannon was then called Pearl class Star Dreadnought

Appearance
The first prototypes of the ship looked like a mix between the Ryuko class Cruiser and a Mako class Destroyer. The cannon was placed on the lower side of the hull. The weapon generator was envolved into a thick layer of Uranium composed armor (900 mm). The biggest drawback of the prototype was that when the gun was fitted, no other heavy weapon could be installed, even small 25 mm cannons wouldn't fit. The Beaver class however, had enough space to house the Gluon cannon and several other heavy weaponry. The appearance of the ship looked a heavily modified Yamato class Space Battleship, lacking it's turrets and front hull

Use on the Battlefield
The Pearl class was highly renowed by the allied commanders because of her capacity of dealing a colossal amount of damage against the enemy while providing herself with a decent defensive firepower. The only drawback was when the gun fired, it needed 5 minutes to shoot another round, but the gun could fire in a constant rate of fire, but the chances of malfunction were bigger. During the tarling invasion of 2038, the Pearl class was heavily used against infected fleets of smaller battleships, wiping out in a fraction of second almost 30 ships per shot. Aprox. 2 ships had fallen on the tarling control. they are now considered high priority targets due to their raw firepower
