The Javelin functioned as a Harrower-class dreadnought and saw action throughout the Galactic War. During the Battle of Corellia, the Sith Empire deployed it in a scheme to eliminate the Rift Alliance Coalition Forces through an elaborate deception. The vessel was intended to appear as though it was guarding troop transports headed towards Corellia, but its true purpose was to detonate once the Barsen'thor and members of the Rift Alliance had boarded. Contrary to the Sith's plans, the Jedi, together with his companions, successfully seized control of the warship.
