Babylon 5 Xill Saucers

Xill Saucers

With the added hull space of a cruiser, the Xill battle saucer is a bewildering ship, as it possesses both strong firepower in every possible arc or angle and exceptional maneuverability. The design originally dates back to the Dilgar Invasion, but the Vree have had it constantly tested and upgraded to use their highest forms of technology. The current antimatter and antiproton weaponry are the best versions they have invented to date, and most races are aware of the mighty firepower of the Xill.

Using the favored hull to create their first true command asset for war purposes, yet retaining the exceptional maneuverability of the mainline Xill, the Xaak is one of the most powerful vessels to be found in any Vree fleet – commercial or military. The original design saw this major internal update and was modified to become a sledgehammer of antimatter weaponry built around a mobile command center and fully functional market base. The Xaak has always been kept, in the minds of the Spacer’s Guild masters, at the forefront of Vree naval design. It is, therefore, a far more expensive ship to build and deploy than other Vree hulls and so tends only to be called upon outside of Conglomerate space in the most important missions.
