The Excalibur class star dreadnought is the follow on to the Arrowhead class.
The wedge shaped design of the Excalibur can be traced all the way back to the Antares class frigate. This is intended to provide maximum frontal firepower, though at the expense of broadside and aft fire. The hangar arrangement is similar to the previous Spear of Saturn and Arrowhead classes, with a large aperture on the lower surface surrounded by landing bays. The bridge is a larger design compared to previous ships, and feature improved command systems. Armament includes the usual 2040 gun batteries, 10.5 batteries forward, 40 MCM silos, and dooms day cannons aft.
- The Excalibur is only the second ship in Zahn's fleet to adopt the standard UAC livery of dark gray with white trim.
- Like most of Zahn's designs, the Excalibur's bridge can be jettisoned in an emergency, allowing Zahn to maintain command even if his ship is destroyed.
- Similar to the Valiant-class Super Heavy Cruiser Everest, Excalibur is used as Zahn's flagship despite being outclassed by other ships he commands.
