The BC-303 is the production model of the X-303, which was introduced in 2003.

History

When the X-303 entered active service, it took the designation "BC-303" and the name Prometheus. It was the first, and for a long time, only deep-space battlecruiser constructed by the Tau'ri. In this capacity, it served as the flagship of the Tau'ri fleet under the auspices of the Office of Homeworld Security.

Though plans were made to construct an entire fleet of BC-303s, the introduction of the Daedalus-class battlecruisers rendered the craft obsolete, leaving the Prometheus as the sole vessel in its class. (SG1: "Enemy Mine", "Moebius, Part 1")

It played a major role in both the Tau'ri-Goa'uld war and Ori crusade until the Prometheus was destroyed in a battle over Tegalus in 2006. The BC-303 class has since been out of service. (SG1: "Ethon")

Technology

As with the X-303 the BC-303 was built using both Earth-based and alien technology, mostly of Asgard or Goa'uld origin.

Shields

The BC-303 utilized shields of Asgard origin, which were donated to them in 2003 as thanks for the help the Tau'ri had provided the Asgard in their conflict against the Replicators. Asgard shielding was first equipped to the Prometheus and eventually the Daedalus-class, allowing the Tau'ri to better defend themselves. (SG1: "Disclosure", "Memento")

These shields are among the most advanced shields known to exist within the known universe.

Asgard transporters

The Asgard first allowed the Tau'ri access to their beaming technology in 2005 during their conflict with the Wraith. However they placed a series of fail-safes into the transporters to prevent the humans from using the technology offensively. Despite this, the Daedalus used its transporters to beam nuclear warheads onto several Wraith hive-ships (with begrudging help from an Asgard), destroying them. The Wraith, however, were able to develop jamming codes that prevented the transporters from obtaining a lock, making the transporters all but useless against the Wraith. (SGA: "The Siege, Part 3")

Besides individuals and small objects, Asgard transporters are capable of beaming large amounts of matter, from complete skyscrapers to entire fleets of ships. (SG1: "Thor's Chariot", "Ex Deus Machina")

Asgard Sensors

The BC-303 must feature Asgard sensors, since they are used as a part of the Asgard transportation technology . These sensors are highly advanced as they can scan and pinpoint life signs from far away, and are also what allows the Asgard beaming technology to lock on to an object accurately.(SGA: "The Intruder")

Engines

Asgard hyperdrive

The BC-303 used hyperdrive technology engineered by the Asgard. The hyperdrive engine was given to the Tau'ri in 2003 as a thanks for their help in the fight against the Replicators. All Tau'ri built ships since has been ourfitted with these powerful engines, which are able to cross the distance between Earth and the Pegasus galaxy in 18 days (or 4 days, using a Zero Point Module). (SG1: "Disclosure")

Sublight Engines

The BC-303 possess relatively powerful sublight engines, which are installed on the Prometheus and the Daedalus-class ships. The sublight engines on the Prometheus were capable of accelerating to 110,000 miles per second, over half the speed of light. (SG1: " Prometheus", "Flesh and Blood")

Sublight engines have varying output which is controlled through the ship's helm. One such output was referred to as "emergency thrust" and was used when the Prometheus left Antarctica to meet Anubis's fleet in Earth's orbit. The second time this output was referred to was when the ship needed to get away from the segments of a Supergate which were on collision courses with the ship near the planet Kallana. (SG1: "Lost City, Part 2", "Beachhead")

Armaments

Railguns

The BC-303 is oufitted with several railguns, which have become standard on F-302s and all Daedalus-class vessels for ship-to-ship combat. Just a few shots are able to take out a Death Glider relatively quickly and deal a large amount of damage to Al'kesh and Ha'taks. However, Ori shields are significantly more difficult, practically impossible, to pierce. (SG1: "Prometheus Unbound", "Ethon")

Missile Batteries

The 303s have 12 missile batteries and naquadah enhanced nuclear warheads. These missiles are able to take out a Death Glider relatively quickly and deal a large amount of damage to Al'kesh and Ha'taks. Ori shields, however, are far more resistant than of most other races. (SG1: "Prometheus Unbound", "Ethon")

Battle Complement

The BC-303 is designed to carry a squadron of eight F-302 space intercept fighters. The fighters are kept in the cargo bay and hangar area at the front of the ship. (SG1: "Lost City, Part 2")
