For those of you who don't know about the daedalus...
The second generation of interstellar space craft developed by the United States military and its allies. 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-8 tactical warheads and a bay of F-302 fighters. It also possesses Asgard shielding and transporter technology, but none of their weapons. To assure that these technologies are not abused an Asgard presence is aboard the ship at all times in the form of an engineering expert from their species. Presently that role is given to the Asgard Hermiod.
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.
