(Capital) RT-class Dreadnought
A super-capital class warship deployed by the Aquarian Imperial Navy. RT-class vessels are built upon the design of the UAS's 'Retribution-II' class dreadnoughts, incorporating many improvements and upgrades as they transition to Imperial Navy service. This class of Warship is the cornerstone of Imperial Terran military might, and the presence of one on a system is usually enough to quell most insurrections before they even start.

The largest and most powerful single military warship currently in service with the Aquarian Imperial Navy. RT-class dreadnoughts get their name from the 'Retribution' designation of the second class to carry that name, the UAS Navy's Retribution II class dreadnought, itself based on the ancient pre-fall Retribution-class Battlecruiser employed by the UTN Navy before being replaced by the well-known Endeavour-class hull still in service today as the ED-class designation.
The RT-class builds upon the solid foundations of the Retribution II it is based on; with an overwhelming emphasis on directed, long-range firepower and immensely powerful shield generators for withstanding the most extreme punishment thought possible to delivery by potential enemies of the Aquarian Imperial States. This transition back to the 'big-gun' warships of the CEG Wars era, itself from the dreadnoughts of the Old Earth water-navies, highlights the importance of directed military might in the 45th century and beyond.
As of 4421 A.D, the Imperial Navy operates six RT-class Dreadnoughts, with two more under construction and another four planned; for a total of twelve warships expected to be in operational service by the end of the half-century.
