The ship was hijacked in early 2617, under mysterious circumstances. Of the total 50,000 serving crew members only the acting captain, Anthony Hawke, survived.

After its hijacking, Dragon disappeared from all galactic surveillance systems; its current whereabouts or fate, a mystery. Around June 2617, it was tracked moving around a number of uninhabited independent-declared regions of space.

The battleship was one of the main targets of Operation Menelaus. The Confederation aimed to recover it by using an in-built fail-safe: a remote deactivation system. The attempt failed when the Pandoran forces occupying the vessel purposely complied with the de-activation request and lured the allied forces into a trap. It then turned its main gun, an antimatter cannon, on Grendel, destroying the ship.

It was summoned as back-up by Anthony Hawke when he failed to destroy Griffin, with Julian Rissard at the helm. The ship's attempt to turn its anti-matter cannon on Griffin failed when it was engaged by the White Knights and five ATAFs. After being hit by the combined forces of five plasma accelerator beams, Dragon was forced out of combat.

Dragon was a latecomer to Coyote, only arriving after the Pandoran forces had evacuated Mythos and had nuked the planet. The battleship's opening act was to immediately take down Erik the Red and another UNF warship, driving into between the two and delivering the full power of its port and starboard accelerator beams to destroy the ships in seconds. It then made to eliminate the more powerful CSN and UNF vessels, targeting Griffin immediately with its anti-matter cannon. It never succeeded, however, the imminent destruction of Grendel's Mother and the danger posed by the explosion of the Tachyon Star Bombs forcing it to abandon its attack. It fled Coyote shortly after the incident.
