During their exploration of the Arctic Circle, the A-6 team discovered a craft of unknown origin. As they investigated the crashed vehicle and its crew, later identified as Borg drones, the members of the team were assimilated, along with their ship, into the Borg Collective. The new drones then attempted a journey in Arctic One to the Collective's territory in the distant Delta Quadrant. While not normally armed with weapons, the Borg assimilated the Arctic One had developed cutting beams and proton bursts.
