BC-304/Oured-class Battle cruiser

The BC-304 class (also known as the Oured-class battlecruiser) is a class of deep space carrier built by Homeworld Command, and is the mainstay vessel of the United Earth Space Fleet. The ships are combination battle cruiser and carrier, with both strong offensive weapons systems such as plasma beams or ultra heavy railguns and the facilitates to launch/recover armed combat spacecraft. The capabilities offered by the Oured-class allow Homeworld Command to project power and conduct offensive operations across multiple galaxies without depending on local bases for staging operations.

Although referred to as "sister ships" to the BC-303 Enterprisa, the BC-304s differ significantly in their design and technology. While the Enterprisa was originally built with reverse-engineered Goa'uld technology and salvaged equipment, the BC-304s incorporated Asgard technology in their base designs. All BC-304s are equipped with Asgard derived shields, sensors, transporters, weapons systems, as well as intergalactic hyperdrive technology that allow the ships to make large intergalactic journeys in a matter of days.

As of 2020, 20 Oured-class warships have been built, with 19 currently in service. The Korolev, the only 304 to be lost in combat, was destroyed in combat with Ori due to the ship being rushed into service in a not complete state to reinforce the Khabovask during the First battle of the Supergate. The ships are split into three base sub classes with a fourth currently under development, the original Oured-subclass, the Hammond-subclass, and the  Aurora-subclass. With the current exceptions of Iran and Pakistan, every nation participating in the Stargate program operates at least one BC-304 under the authority of Earth Fleet Command.
