The BC/DSC-304, also known as the Daedalus-Class warship, is a Deep Space Carrier or more appropriately, Battle Cruiser, built by the Tau'ri, and is the most advanced human-built series of vessels in the IOA Space Forces. As of 2011, nine Daedalus-class battlecruisers have been developed, seven commissioned, and two under construction. The Korolev, which was handed over to the Russian Federation, was lost in the battle with the Ori.
