Daedalus-class 304 Battlecruisers (sometimes known as a Deep Space Carrier) are fictional spacecraft in the science fiction television shows, Stargate SG-1 and Stargate Atlantis.

The 304 is the second-generation line of Earth's battlecruisers, designed to combat massive ships such as the Goa'uld motherships, succeeding the Prometheus. There are currently two confirmed active spacecraft in the Daedalus class series: the USAF-operated Daedalus and Odyssey. The third ship in the class, the Russian Air Force-operated Korolev, was destroyed during the Battle of P3Y-229.

Alien technology

Template:Sgspoiler Template:Sgspoiler The Daedalus class is fitted with much of the same advanced alien technology as the Prometheus, only all integrated into the original design before construction, as opposed to being "tacked on after the fact" as was the case with the Prometheus, as Lt. Col. Samantha Carter put it.

Asgard

The Daedalus class is equipped with a great deal of Asgard technology, notably its intergalactic hyperdrive, shields, and beaming technology. In addition, the Daedalus itself has an Asgard engineer named Hermiod assigned on board to oversee its use.

While generous with propulsion, support, and defensive technologies the Asgard were more wary of providing offensive technologies that could be used against them, and so the Daedalus class does not have any Asgard weaponry. In addition, the beaming technology has in-built safeguards to prevent their use as weapons delivery systems (such as their being used to beam a nuclear weapon on board a Wraith Hive Ship). Despite this, the Asgard Hermiod has overridden these safeguards on board the Daedalus on numerous occasions and there have been instances of both the Odyssey and the Korolev beaming or attempting to beam nuclear warheads apparently without consulting an Asgard to override the safeguards.<

Although the Prometheus also had Asgard shield technology, it is implied that the Daedalus's shields are superior: The Ori satellite weapon installed over the planet Tegalus was able to penetrate the Prometheus's shields with a single shot, whereas the Daedalus class shields were able to withstand single hits from the main weapon of an Ori Battlecruiser, which appeared to shoot the same kind of beam as the satellite weapon. However, since it is unknown if the power output of the satellite weapon is the same as the Ori Battlecruiser weapon, this cannot be confirmed.

Goa'uld/Ancient

The Daedalus class ships also have the same ring transporters as Goa'uld vessels, which are now known to ultimately be an Ancient creation.

Weapons

The Daedalus class carries numerous Mark VIII tactical nuclear warheads and Mark III tactical nuclear warheads, and a large number of rail guns. Generally speaking, the primary armament used by the Daedalus is her missile complement which is fired using a vertical launch system with all her missile emplacements appearing at the bow of the ship. Unlike normal vertical launch systems, it is possible to access the loaded missiles from inside the ship to swap their warheads, or entire missiles. In Season 3's No Man's Land, Col. Caldwell ordered the safety protocols to be disabled so they could fire their Mk. III missiles the moment they exited hyperspace to increase the chance of them getting through and getting by the Wraith darts.

There is no Asgard weaponry on the Daedalus, with the Asgard going as far as to safeguard their beaming technology to prevent its use as a weapons delivery system.

Hangar Bay

The Daedalus class has two hangar bays on either side, but all the F-302's are in the port side hanger. The Daedalus is capable of carrying up to 16 F-302s, but so far its only been seen carrying 8 so that the other hanger can be used for various needs.

Design

As seen on Stargate Atlantis, the Daedalus has notable physical differences from the Prometheus. She is sleeker, without the large aft tower. She also has three additional engine emplacements on each side, making the rearmost part of the ship wider than the Prometheus. There is a large square structure on the ship's bow, its purpose is unknown. F-302 bays are located on both sides of the ship, below and out from the main hull along the rear. The Daedalus shields are also capable of standing up to multiple Wraith Hive Ships or Goa'uld motherships in combat.

It has been noted on SG1 that the 304s come out of Area 51 one by one, but can be produced faster. In a teaser for the Atlantis Season three finale, it is stated that a new ship, the Apollo, will be entering service. It is unknown if the Apollo will be a Daedalus Class battlecruiser.

Daedalus

Overview

The Daedalus (a 304) is the first starship to be produced of the Daedalus class of battlecruisers, and carries an Asgard engineer (Hermiod) to oversee the ship's Asgard technology. It is believed that each ship takes about one year to construct and at least 3 Daedalus battlecruisers have been built with 2 being constructed in a year (The Korolev was rushed into service months before schedule).

Appearance on the show

The Daedalus was first mentioned on Stargate SG-1 in episode 8.19, "Moebius, Part 1", and on Stargate Atlantis in episode 1.20, "The Siege, Part 2". She made her first appearance in Stargate Atlantis episode 2.01 "The Siege, Part 3".

History

File:Daedalus in orbit of Atlantis.jpg

Daedalus orbits Atlantis

The Daedalus was launched from Earth after the Zero Point Module was found in Egypt and was used to send a force of Marines to Atlantis with it. It took the Daedalus only four days to reach the Pegasus Galaxy and Atlantis with the ZPM powering the ship's Asgard hyperdrive. This ZPM was removed and used to power Atlantis's shield. Without the Ancient power source, it takes Daedalus approximately 3 weeks to travel between Earth and Atlantis.

In addition to serving as an effective transport, the Daedalus has experienced marked success in its function as a warship. With the main threat in the Pegasus Galaxy being the Wraith, the Daedalus is usually pitted against Wraith Hive-Ships, which severely outclass the smaller ship in size, firepower, and the capability of carrying fighter craft. The overall size of the vessels make them difficult to destroy with anything less than nuclear weapons, which are carried in only limited numbers and are easily destroyed prior to detonation against a Hive-Ships hull. However, the advanced Asgard shielding aboard the Daedalus has allowed her to stay in a battle long after a Hive-Ship would have succumbed, and she has held her own in battle against the Wraith (sometimes against more than one Hive-Ship) and has scored numerous kills against the larger vessels.

The ship is named after the architect and engineer Daedalus of Ancient Greek mythology and is commanded by USAF Col. Steven Caldwell.

Odyssey

The USS Odyssey orbits Earth in "Off the Grid"

The second USAF production spacecraft of the Daedalus class Battlecruiser is called the Odyssey registry PB3865 Deep Space Carrier. Its design, weapons, and technological capabilities are identical to the Daedalus.

After the destruction of the Prometheus in "Ethon", the Odyssey became the primary vessel in Earth's defensive fleet.

Initial mission

During the shakedown cruise of the Odyssey, the commander of the vessel, Colonel Emerson, was sent by General Landry to rescue SG-1, who were captured by the Lucian Alliance on P6G-452. SG-1 had been captured after the Stargate on the planet was taken by Baal, preventing them from dialing home.

The ship traveled to the P6G-452 in hyperspace, and using implanted identification chips that were placed in all SGC personnel, the Odyssey was able to lock onto and beam them aboard. The ship was then immediately contacted by General Landry to go and reclaim the Stargates from Ba'al's mothership. SG-1 beamed aboard after Ba'al's ship was disabled and planted tracer beacons on all the Stargates and DHDs, while in the middle of fending off Ba'al's Jaffa. The Lucian Alliance showed up in a small fleet of Ha'tak vessels and ignored the Odyssey's hails, and they attacked Baal's ship. The Odyssey began to fire on the Lucian ships with rail guns in order to prevent them from destroying Ba'al's ship while SG-1 was aboard. The Odyssey then managed to beam all but one Stargate and DHD before the Lucian ships destroyed Ba'al's. That particular Stargate was being used by SG-1 to gate back to Earth, but Colonel Emerson and the Odyssey had to assume the worst and retreated after the shields were nearly drained and after doing no damage to the Lucian fleet.

During the Odyssey's first mission, its shields were untested and were not operating at 100%.

By the time of Template:Sgcite, the Odyssey was among several other Jaffa/Asgard/Human/Tok'ra ships to form a fleet tasked with destroying the Ori supergate. Along with the Russian cruiser, Korolev, the ship engaged in combat with the Ori once the first wave of the enemy fleet breached the supergate. The ship suffered heavy damage, but was one of the few ships to survive the battle. Her crew was able to repair most systems in time to rescue the members of SG-1 and Bra'tac before Bra'tac's Ha'tak was rammed into an Ori battlecruiser in orbit of Chulak.

The Pegasus Project

In Template:Sgcite, the Odyssey was dispatched to the Pegasus galaxy in an attempt to create a stable wormhole between Pegasus and the Ori Supergate in the Milky Way galaxy, to prevent the Ori from sending more ships through it. Attempts by the Asgard to dial out of the gate had already failed; the Supergate could only be dialled into from another Galaxy, and there was insufficient energy produced by a standard Stargate to establish a connection. The Odyssey positioned a Stargate near a black hole in Pegasus and, using the black hole as the Stargate's power source, established a connection with a Stargate that had been placed in close proximity to the Supergate. Once established, the Odyssey beamed shaped nuclear charges in front of the Stargate in an attempt to force the outgoing wormhole to jump to the Supergate, thus forming a connection to it. With a black hole powering the Stargate, the connection could be maintained indefinitely.

The Odyssey performed several unsuccessful attempts to jump the wormhole to the Supergate before a Wraith Hive-Ship detected the nuclear detonations and attacked the Odyssey. Performing a slingshot manoeuvre around the black hole's gravity well, the Odyssey beamed its remaining nuclear warheads into the Hive Ship that was pursuing them just as it passed by the Stargate. When the weapons were detonated, the resulting detonation of both warheads plus the Hive Ship sent enough energy through the Stargate to cause the wormhole to jump to the Supergate. In addition, the massive unstable vortex produced by the activation of the Supergate engulfed an Ori battlecruiser, destroying it.

Lucian Alliance hijacking

In the episode "Company of Thieves", the Odyssey was dispatched by Stargate Command to investigate the possibility of another Ori Supergate. Once they arrived on-scene, however, they were ambushed by several Ha'tak vessels and forced into a minefield which, because their shields were weakened by a nearby neutron star, rendered the ship disabled. Soon boarded and seized, it is revealed that their assailants were members of the Lucian Alliance who had been sent to destroy or capture the vessel. Demanding that Col. Carter repair the damage and disable the distress beacon revealing their location, the members of the Alliance kill Colonel Emerson when he orders her to not assist them in any way.

Acting as though she was repairing the ship, Carter attempted to stall the hijackers until an escape attempt could be made, an opportunity which afforded itself when Daniel and Vala were likewise captured and brought to the Odyssey. After retaking the ship and killing the leader of hijackers in the process, the crew returned the Odyssey to Earth for repairs.

Korolev

The Korolev was a 304 given to Russia by the USA in exchange for continued use of the Russian Stargate, and was commanded by Colonel Chekov. Just prior to the Battle of P3Y-229, Korolev was rushed to duty in order to defend against an invasion fleet of Ori battlecruisers. The ship was only partially finished, with a year of construction remaining; however, her major systems were complete and she was fully space worthy.

Korolev carried a compliment of F-302's, having also acquired their plans in the Russian Stargate exchange. She was equipped with Asgard beaming technology, as demonstrated on Dr. Jackson and Col. Mitchell.

In the Russian language sequences of "Camelot", the ship's name was spoken correctly as Karalyov, commemorating Russian rocket scientist Sergey Korolyov. In the English language sequences, it was pronounced as it is written in English, which is incorrect. This could be ascribed to the American characters not knowing the correct pronunciation, except that Daniel Jackson, who speaks excellent Russian, also makes this mistake; however, this could have been intentional so as to avoid confusion.

The Korolev was destroyed by two concurrent hits from Ori ships. Only 6 of her crew were saved by beaming to the Odyssey; it is unknown who survived. Dr. Jackson escaped by ringing aboard one of the Ori ships and Col. Mitchell made it to a F-302.

Apollo

The Apollo is the name of the new Earth ship, which will be appearing in the Stargate Atlantis Season Three finale "First Strike"'.

Apollo is sent to Pegasus with new orders: her captain, Colonel Abe Ellis, will be commanding a preemptive strike against a fleet of Asuran vessels that is under construction. The Daedalus will be fighting alongside Apollo against the Asuran ships.

Very little other information on the Apollo is availible so far, including whether it is or is not indeed a Daedalus class ship or a new class of ship.

Battle of P3Y-229

File:Deadalus Class Ship -- Absorbing fire.jpg

Odyssey absorbs fire.

In the Season 9 finale, Template:Sgcite, the Odyssey and Korolev were both a part of a combined Tau'ri, Jaffa, Asgard, Tok'ra and Lucian Alliance fleet sent to intercept and stop the Ori fleet from arriving through a Supergate constructed around P3Y-229. The Lucian Alliance ships are shown to arrive late into the battle. The Asgard vessel was an O'Neill class battleship piloted by the Asgard Kvasir. En route, the Korolev was ordered to collect SG-1 and report immediately to the Supergate. Their standing orders were to destroy the Supergate by any means necessary.

The episode shows both the Odyssey and Korolev faring better than the Jaffa vessels in the opening moment of the engagement; apparently, their Asgard-designed shields were far better at withstanding the opening attacks from the Ori vessels. Although the episode didn't show the Asgard vessel being destroyed, it was seen fighting the Ori ships and taking numerous hits which appeared to be absorbed by its advanced shielding. However, as the engagement continued, both Earth vessels lost main power systems and main engines, rendering them sitting ducks to the Ori weapons.

Nearing the conclusion of the battle, with most of the vessels opposing the Ori destroyed, both Odyssey and Korolev remained largely intact (though incapable of continued combat), until a number of Ori vessels concentrated their fire on the Korolev, cutting the vessel's hull in half before the ship exploded.

At least one F-302 of the Korolev survived its destruction and was retrieved by the Odyssey following the conclusion of the engagement. Only six members of the Korolev's crew were beamed aboard the Odyssey. Daniel Jackson used a set of the Korolev's rings to escape onto an Ori ship and Colonel Mitchell used an F-302 to escape the Korolev. Colonel Chekov's fate is unknown.

Trivia

• Daedalus was a mythical inventor from ancient Greek Mythology, who fashioned wings for himself and his son to fly away from Greece. This name is fitting for the Daedalus as it is the first vessel designed by humanity to travel between galaxies. It may also be a nod to Project Daedalus.
• The Korolev is probably named after General Designer Acad. Sergey Pavlovich Korolev, who was the head engineer and designer in the Soviet Sputnik and Vostok programs, moon program and ICBM development.

• Each of the ships appears to be color coded. The Prometheus was Blue, the Daedalus is Green, the Odyssey is Orange and the Korolev was Purple; this is indicated by the maps colour behind the colonel's chair and the lighting of the ship. Just as well each ship also has color coded lights on the sides of the fighter bays where the name of the ship is, the Daedalus has blue lights, the Odyssey has green and the color of lights of the Korolev is indeterminable.

• Odyssey carrying the U.S.S. prefix is technically in volation of U.S. Military regulations. U.S.S. or United States Ship specifically denotes a vessel owned and crewed by the United States Navy. It does not cover the entire armed forces. Vessels belonging to other armed services are given their own prefix such as U.S.C.G.C. for a Coast Guard cutter and U.S.A.V. for an Army owned ship. Given their Army heritage, United States Air Force Vessel (U.S.A.F.V.) would be the correct prefix.
