Sol-class dreadnought

The Sol-class dreadnought is a class of eight vessels of the Terran Federal Navy. They were put into service in late 2645 towards the end of the Great War. They were designed to be so large as to neglect damage inflicted upon them by all but the heaviest of Allied weaponry. Of the initial twelve planned ships, only eight were built as focus shifted on the Jupiter-class supercarriers. 
The Sol-class is the largest combat-oriented class in the Terran or any other navy. The Surben Ved'ji-class heavy cruiser is only two-thirds of the Sol-class' length and half its volume. The Sol-class' largest weapons, the Rosenthal-made Longinus Superheavy Kinetic Accelerators, can pierce through any shielding currently available and is likely to destroy any frigate or smaller vessel in one hit. On the other hand, the Sol-class' heavy armour and shielding make it impervious to most forms of attacks.
