The Excalibur is one of two prototype ships built by Edgar Industries for the Interstellar Alliance. The other ship was the Victory. The two ships were intended to be the first in a fleet of Victory class heavy destroyer vessels. Despite being built for the Interstellar Alliance the ship is crewed by Earth Force personnel and not rangers during a Call to Arms & Crusade.

Excalibur features energy and particle beam weapons. The forward guns operate at two main power levels. Level One provides beams with little more fire power than a White Star. Level Two is much more powerful weapon, reverse engineered from Vorlon

The discharge is a pulse which originates from three emitters mounted on large "fin" structures at the ship's stern; the beams converge just forward of the bow into a single ravening blast that can destroy nearly anything in its path. The weapon is capable of destroying ground installations through the atmosphere of a planet. Firing this titanic weapon drains all the ship's power and the "Excalibur" is unable to maneuver, fire weapons or use long-range scanners for approximately one minute afterward.

 was able to convince Earth's government to mobilize a large fleet to protect Earth, Excalibur and Victory were able to join this fleet. Sheridan and Anderson were able to destroy the planet killer, however Victory was destroyed in the process. Destroying the planet killer distracted the fleet, and the Drakh were able to get close enough to seed Earth's atmosphere with a plague. On their withdrawal, the Drakh destroyed the construction dock - which prevented any further Victory type ships from being built in the near future.

 took command of the ship, and with his crew set out to find a cure to the plague before the plague activated five years later. The beginning of this quest to discover a cure was shown on the Crusade television series.

It is known from other Babylon 5 episodes set further along the time-line than Crusade, that Excalibur succeeds after around 18 months (half-way through what would have been the second season) in finding a cure to the plague. This discovery, however, would lead to the grand revelation of a deeper story line in classic Babylon 5 style: the attack on earth is just a single battle in a larger war. The ship's future has not been documented. It remains to be seen if the ship will make any future television or movie appearances.
