An advanced Asgard space vessel, serving as the template for a new class of Asgard battleship. The Asgard named the craft after Colonel Jack O'Neill after a very effective impression, as the Asgard saw humanity's potential in him.
The vessel was equipped with advanced weapons and defenses that surpassed any of the previous Asgard starships -- the most advanced ship ever constructed by the Asgard. This was enough to make Replicators pursue it. A trio of Replicator-infested Asgard ships gave chase to the remotely controlled vessel, leading them away from an Asgard world under threat. Once in hyperspace, the O'Neill was blown up, oblitarating the Replicator-controlled ships that had been in pursuit.
