Dreadnaughts are currently the backbone of the United Alliance's Peace Keeping Force STAR COMMAND.
Mark ONE, TWO and THREE (see graphics below) anchor FLEET Operations while MARK FOUR (see graphic) are equipped with a detatchable BATTLE RING (see graphic) which provides the CRAFT greater flexibility.
When a Dreadnaught anchors in a Star System which is not an ALLIANCE member world it becomes a STARBASE for United Alliance operations in that theatre.
The differences between MARK ONE, TWO and THREE largely have to do with interior POWER DISTRIBUTION systems, Computer/System CORES with the SIDE WEAPON BANKS being the most obvious external indicator of the difference.
Many of the line have been destroyed but a few, most notably the UAC INDEPENDENCE (SCC-1776), have survived, been upgraded for modern operations and flourish.
Dreadnaughts MARK ONE, TWO and THREE were designed and built during the SOLAR GROUP ALLIANCE years of the MEG WAR for combat/theatre operations.

The detatchable BATTLE RING of MARK FOUR DREADNAUGHTS allow the CRAFT to depart the anchor zone and even engage in tactical operations while the BATTLE RING assumes the STARBASE function. In this respect the MARK FOUR has earned distinction as the preferred MOBILE STARBASE vehicle.
The DREADNAUGHT line is expected to be phased out with the introduction of both HARTWELL Star Systems' IDAHO Class DESTROYER's and RIJL Aerospace's soon to be launched EXPLORER Class Starships.
