The second generation of interstellar space craft developed by the United States military and its allies, and the pioneer in the Daedalus-class battle cruiser (BC-304 class). 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 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. Following the Asgard's extinction the ship, along with the rest of Earth's cruisers, was outfitted with the advanced beam weapon.

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.

With its sister ship Apollo the Daedalus was a major force in the war with the Replicators, culminating in an allied attack on Asuras and the destruction of the Replicators' homeworld.
