The second generation of interstellar space craft developed by the United States military and its allies, and the pioneer in the Daedalus
-class battlecruiser. Commanded by Colonel Steven Caldwell
, her original mission was to render aid to the Atlantis expedition
trapped in the Pegasus Galaxy
and defeat a convoy of Wraith hive ships
bent on destroying the Ancient city.
The Daedalus is armed with rail guns, Mark XIII tactical warheads and a bay of F-302 fighters. It also possesses Asgard shielding and transporter technology, but (at least initially) none of their weapons. Prior to the Asgard's mass extinction an Asgard scientist, Hermiod, was assigned to the ship in order to assure that their technologies are not abused.
Propulsion consists of standard thrusters as well as an Asgard hyperdrive engine, capable of traveling one way between Earth and Atlantis in 18 days. The ship's primary mission is now to ferry personnel and supplies from Earth to Atlantis, and then to travel back again, but the Daedalus often stays in the vicinity of Atlantis for some time before making another loop.
