The Odyssey was summoned to Orilla by the Asgard to receive a massive upgrade of all Asgard technology as well as receiving all the Asgard's knowledge. The ship received an Asgard computer core, presumably newly improved shields, and Asgard plasma beam weapons, among other upgrades. However, being able to detect the new Asgard upgrades through subspace, three Ori warships became aware of their location and emerged from hyperspace to attack. (SG1: "Unending")
