For the Daedalus Class, see BC-304.

The Daedalus could be considered a sister ship to the USS Prometheus and was the first in the line of the second generation of interstellar capital ship developed by Earth.

It was originally commanded by Colonel Steven Caldwell and was the main support vessel for the Atlantis Expedition until the arrival of the USS Apollo. The Daedalus had participated in many major battles in the Pegasus Galaxy before its decommissioning in 2020. It was Commanded by Colonel Kevin Marks, long time 304 crewman, during the last year of it's career. It was decommissioned and recycled, with several components, such as it's port hanger bay, Ancient Core and Asgard Weapons going on to be used on newer ships.


The USS Daedalus is named for the fabled engineer and creator of the maze of Knossos, home of the Minotaur. For creating the maze, he was imprisoned within a cell with his son, Icarus, so that he could never reveal it's secrets. To escape the cell, he built wings of feathers and wax for he and his son (Icarus), who fell to his death when the sun melted the wax on his wings when he dared fly too close to the sun.

The space-faring USS Daedalus (X/BC-304-1) is the second military vessel to carry the name, the first being the USS Daedalus (ARL-35), a repair vessel for supporting amphibious landing craft. Launched and commissioned in 1945 in the waning months of World War II, the vessel was decommissioned in the years following the war, in 1947. The ship was sold to a private company in 1960, with it's fate unknown after that.

Alternate TimelinesEdit

  • In an alternate timeline, the USS Daedalus (under the command of Colonel Maria Sobel, USAF) was affixed with a prototype drive, and a Subspace Capacitor, causing it to accidentally jump between universes on a regular basis.
  • In an alternate timeline, the USS Daedalus remained in service until at least 2039, where one of its helmsman was Estragon Turner.
