Prometheus

The prototype of the X-303 series, Prometheus was hijacked before completion by rogue NID agents demanding the release of Colonel Frank Simmons and the Goa'uld infested Adrian Conrad. SG-1 managed to reclaim control of the ship, and were enlisted by the Asgard to help them trap the Replicators within a time dilation bubble. The Asgard thanked Earth by fitting advanced systems onboard the X-303.

The ship was subsequently finished and began a shakedown cruise. A problem with the Hyperdrive engines forced the crew to eject the reactor into space, stranding the ship on an alien world.

Prometheus remained there until she was fitted with the hyperdrive taken from a captured Al'kesh bomber. Unfortunately this meant that the ship was underpowered, since the Al'kesh reactor couldn't generate the power needed to fully operate Prometheus. She returned to Earth, but was attacked by an unknown alien ship en route and suffered damage while hiding from it inside a corrosive nebula. The damage was repairable, however.

Prometheus served in the defense of Earth from Anubis' forces, and was almost destroyed before the Ancient weapons found in the Antarctic Outpost were activated.

The ship is operated by the U.S. Air Force, and its crew consists of Air Force personnel. Operationally Prometheus (and her following sister ships) are under the Pentagon's "Office of Homeworld Security".

The Prometheus uses Asgard technology in its hyperdrive engine and in its weapons and shields (There may be other uses of Asgard technology installed). This technology was fitted by the Asgard in return for Earth's help in fighting the Replicators. It also relies on some Goa'uld technology the most notable being the transport rings, based on the Ancient's Stargate design.
