The Excalibur

Juggernaut SSD The Excalibur is the flagship of the Sith Imperator, Darth Mobius. It is over 15,000 kilometers long, even longer than an average planet! Darth Mobius constructed the ship, along with the Gyges and Kotos Super Star Destroyers, To form a near-indestructible dreadnought capable of taking out entire fleets with minimal effort. The Excalibur is armed with several powerful Superlasers, with its main cannon being powerful enough to destroy entire planets with a single shot. It was built over a period of 37 years by Mobius' Sith Engineer Droids, and is now used as a Superweapon to eliminate entire fleets at once, without leaving any traces of its existence. It is also used to force Separatist-Controlled Systems to switch sides to the Republic, to avoid getting crushed by the Excalibur.
