The Prometheus (also known as the X-303 and later BC-303) was a US military spacecraft and the first Tau'ri capital ship. It was originally planned for several more ships of the Prometheus-class to be constructed, but instead the Daedalus-class battlecruisers were designed.
The sole ship in her class, the Prometheus was a prototype, serving as a testbed for reverse engineered technology which was later used in the more advanced Daedalus-class. The ship was launched in late 2002, whereupon it was hijacked by rogue NID agents.
In early 2003, the Prometheus temporarily lost hyperdrive capability when it was forced to eject the naqauadria reactor powering its hyperdrive over Tagrea. Later that year, the Prometheus recieved a new reactor from an Al'kesh stolen by Jack O'Neill and Teal'c. After returning to Earth, the Prometheus underwent a refit to replace the hyperdrive and Al'kesh reactor.
In late 2004, the Prometheus was placed under the command of Lt. General George S. Hammond during the Battle of Antarctica. During the battle, General Hammond ordered the Prometheus to ram Anubis' Flagship. Howerever, it proved unneccesary as SG-1 managed to locate the Ancient outpost under the ice of Antarctica and use it to destroy Anubis' Fleet.
Afterwords, the Prometheus was refitted with various Asgard technologies as well as railguns. After its refit, General Hammond took the Prometheus on a mission to the Pegasus galaxy though it never after being attacked by several Al'kesh and gliders which damaged the ship. In 2005, it was part of a force that stopped the Ori from gaining a beachhead on Kallana. In early 2006, the Prometheus was destroyed by an Ori Satellite Weapon over Tegalus.

- Mark Nine Naquadriah enriched nuclear warheads.
The Prometheus' original hyperdrive was capable of achieving at least 237,383.28c. After losing the naquadriah reactor, it was given the reactor of an Al'kesh which allowed it get home. The intergalactic hyperdrive on the Prometheus could achieve speeds of over 50,000,000c allowing it to get to the Pegasus galaxy in three weeks, though the Prometheus tended to cruise around at 1,314,900c when inside the Milky Way
