The Daedalus in deep space.

The Daedalus-class battlecruiser (also known as the BC-304) is a Tau'ri capital ship. Based off the earlier Prometheus, the Daedalus was an improved design that was put into mass production. A Daedalus-class ship can carry up to sixteen F-302 fighter craft. It is capable of reaching the Pegasus Galaxy in eighteen days, suggesting a cruise speed of approximately 115 Light-years per minute. In 2007, the Daedalus-class was refitted using Asgard technology. The Daedalus was launched in 2005 to defend Atlantis from the Wraith. A Daedalus-class vessel is 611 meters long.[1]
