Background
Although no specifications regarding this new ultimate weapon have yet been obtained from our Intelligence Agents in the Core Worlds, the following general characteristics have been identified. It is assumed the current Emperor's Hammer Flagship, the SSSD Sovereign, is a design primarily based upon technologies to be refined in the ESSD Eclipse...

The Axial Superlaser: The main weapon aboard the ESSD Eclipse is 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 Eclipse 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 sear whole continents in a flash.
