Sovereign Super Star Destroyer
The Sovereign-class Super Star Destroyer was a huge 15-kilometer-long warship. In terms of scale, they could be seen as successors to the Eye of Palpatine and the Kuati Star Dreadnoughts that preceded the New Republic era.
They were to be the penultimate Imperial weapon, surpassed only by the
Eclipse-class Super Star Destroyer. The Sovereign was essentially a smaller cousin to the
Eclipse-class design, with fewer weapons, a slower hyperdrive, and a smaller complement of starfighters and crew. Nevertheless, the
Sovereign-class ships were vastly larger than almost any other warships they might encounter, and designed to instill fear in any enemies of the Empire.
The main weapon aboard the Sovereign-class Super Star
Destroyer was the axial superlaser. A spine-mounted superlaser modeled on the main weapon of the Death Star itself. The Death Star's prime weapon was composed of eight individual lasers that could focus together, generating enough power to destroy an entire planet. By comparison, the Sovereign carries only a single laser, but recent focusing and generator advances make this ray much more powerful than the units used on the Death Star. The beam packs enough destructive power to shatter the most powerful planetary shields and devastate planets
Many Sovereigns were planned, with the first, Sovereign, undergoing construction at the time of the first defeat of the Emperor's clone. Only three additional ships were known to have been named at the time of the project's cancellation: Autarch, Heresiarch, and Despot. Whether any of these ships were actually built is unknown, but it is believed that all ships under construction were lost when Byss was accidentally destroyed by the Galaxy Gun.
