EspañolDAEDALUS CLASS BATTLECRUISER
The '''Daedalus''-class battlecruiser' is a fictional starship in the science fiction television series ''Stargate SG-1'' and ''Stargate Atlantis''. Also referred to as a Deep Space Carrier[1] and a 304,[2] the ''Daedalus'' class is the second generation of Earth battlecruisers and is designed to combat enemy ships, such as the Goa'uld ''Ha'tak''-class mothership. It succeeds the ''Prometheus'' as the main vessel operated by the United States military and its allies on the two series.
Four ''Daedalus'' have been built and three are in active service, including the USS ''Daedalus'', the USS ''Odyssey'' and the USS ''Apollo''. The Russian Air Force-operated ''Korolev'' is destroyed during the Battle of P3Y-229.[3]
Technology
The ''Daedalus'' class is equipped with much of the same advanced alien technology as the ''Prometheus'', only all integrated into the original design prior to construction, as opposed to being "tacked on after the fact", as Lt. Col. Samantha Carter puts it,[4] as is the case with the ''Prometheus''.
Asgard
The ''Daedalus'' class contains a great deal of Asgard technology, notably its intergalactic hyperdrive, shields and beaming technology. The ''Odyssey'' is also equipped with energy weapons, an Asgard computer core, and other technologies, with Samantha Carter describing the Asgard technology as "truly amazing". In addition, the ''Daedalus'' itself has an Asgard engineer named Hermiod assigned on board to oversee its use. When temporarily genetically enhanced, Rodney McKay enhanced the shields on the ''Daedalus''.
Goa'uld/Ancient
The ''Daedalus'' class ships also have the same ring transporters as Goa'uld vessels, which are known ultimately to be an Ancient creation.[5] These rings are compatible with rings onboard Ori motherships.
Tactical systems

''Odyssey'' fires energy weapons
The ''Daedalus'' class carries numerous Mark III[6] and Mark VIII[7] tactical nuclear warheads and a number of railguns. Generally speaking, the primary armament used by the ''Daedalus''-class vessels is the missile complement which is fired using vertical launching systems, with all missile emplacements appearing at the bow of the ship;[8] only the ''Odyssey'' has been seen with ventral hull emplacements.[9] Unlike conventional vertical launch systems, it is possible to access the loaded missiles from inside the ship, to swap their warheads, or entire missiles. In season three's "No Man's Land", Colonel Caldwell orders the safety protocols to be disabled so that it is possible for them to fire all their Mk. III nuclear missiles the moment they exit hyperspace to increase the chance of a missile achieving a direct hit and not being destroyed by the Wraith Darts.
In addition to a thick armor hull that is capable of withstanding brief but intense fire from a Wraith Hive-Ship, the ''Daedalus'' class vessels are fitted with advanced Asgard shielding that can defend the ship from incoming hostile fire.
There is no Asgard weaponry fitted to any ''Daedalus''-class vessels prior to the ''Stargate SG-1'' finale episode, "Unending", with the Asgard previously going so far as to safeguard their beaming technology by preventing its use as a weapons delivery system.4
During the series finale, however, the ''Odyssey'' is heavily upgraded with the latest Asgard technology, including an Asgard computer core and energy weapons capable of successfully destroying an Ori mothership with several direct hits to its shields.
Design
As seen in ''Stargate Atlantis'', the ''Daedalus'' has notable physical differences from the ''Prometheus''. It is sleeker and lacks the large aft tower. The ''Daedalus''-class also has four additional engine emplacements on each side, making the rearmost part of the ship wider than that of the ''Prometheus''. There is a large square structure on the ship's bow the purpose of which is unknown. F-302 bays are located on both sides of the ship, below and out from the main hull along the rear.

Hangar bay
The ''Daedalus'' class has a hangar bay on either side, but all the F-302s are in the starboard hangar. The ''Daedalus'' is capable of carrying up to 16 F-302s, but so far it has only been seen carrying eight so that the other hangar can be used for various needs. The hangars come with doors and shields to prevent decompression and expulsion into space.
Ships of the Line
The USAF operated ''Daedalus'' (Hull-marked 02) first appears in the ''Stargate Atlantis'' episode "The Siege, Part 3", commanded by Colonel Steven Caldwell. The ''Daedalus'' plays an instrumental role in defending Atlantis, and subsequently serves as an intergalactic ferry between Earth and Atlantis.
USS ''Odyssey'' first appears in the ''Stargate SG-1'' episode "Off the Grid", and becomes Earth's primary-defense when the ''Prometheus'' is destroyed in "Ethon". ''Odyssey'' is commanded by Colonel Paul Emerson from "Off the Grid" till "Company of Thieves" when he is killed in the line of duty. The ''Stargate SG-1'' episode "Family Ties" reveals ''Odyssey''
The Russian ''Daedalus'' class vessel ''Korolev'' appears in the season nine finale, "Camelot", under the command of Colonel Chekov. The ''Korolev'' is destroyed in battle by two Ori motherships.
Appearing in the ''Stargate Atlantis'' season three finale, "First Strike", the ''Apollo'' (Commanded by Abe Ellis) is used in a pre-emptive attack against the Asurans.
The map color behind the colonel's chair and the lighting on each of the ships appears to be color coded. The ''Prometheus'' is white,[10] the ''Daedalus'' is green,[11] the ''Odyssey'' is orange,1 the ''Korolev'' is purple3 and the ''Apollo'' is Blue/Indigo.8
''Daedalus''
The ''Daedalus'' 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 four ''Daedalus'' battlecruisers have been built with two being constructed in a year (the ''Korolev'' is rushed into service months before schedule). This may be a result of the funding change that Military Appropriations enacted at the beginning of season nine of SG-1, where 70% of the SGC funding is transferred to 304 production.
First mentioned in the ''Stargate SG-1'' episode "Moebius, Part 1" and in the ''Stargate Atlantis'' episode "The Siege, Part 2", ''Daedalus'' makes its first appearance on ''Atlantis'' in the episode "The Siege, Part 3" at the beginning of season two. Since then, it has become one of the regular components of the series, primarily serving as a carrier between the Pegasus and Milky Way galaxies.
''Daedalus'' is also mentioned in several ''Stargate SG-1'' episodes, including "Ethon", "Company of Thieves", "Camelot" and "The Shroud" (where the ship is engaged in a joint operation with the ''Odyssey'' to destroy a Pegasus Stargate using a Mark IX tactical warhead for the purpose of disengaging the Ori Supergate).
History
The ''Daedalus'' is launched from Earth after the Zero Point Module is found in Egypt[12] and is used to send a force of Marines to Atlantis with it. It takes the ''Daedalus'' only four days to reach the Pegasus Galaxy and Atlantis with the ZPM powering the ship's Asgard hyperdrive, and while installed, the ZPM provides a significant increase in shield power.[13] This ZPM is removed and used to power Atlantis's shield. Without the Ancient power source capable of powering the Asgard hyperdrive at full power, it takes ''Daedalus'' approximately three weeks to travel between Earth and Atlantis.[14]
Hermiod, the ship's Asgard technical advisor, is able to temporarily run the hyper drive at much greater level so as to increase hyperspace speed enough to make it back to Atlantis in time to warn them about a Trust plot. This action places ''Daedalus'' at great risk of burning out the ship's engines.[15]
In addition to serving as an effective transport, the ''Daedalus'' has experienced marked success in its function as a battleship. 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, fire-power and fighter craft carrying capacity. The overall size of the vessels make them difficult to destroy with anything less than nuclear missiles, which are carried in only limited numbers and are easily intercepted by sacrificial Wraith darts long before reaching the Hive-ship. However, the advanced Asgard shielding aboard the ''Daedalus'' has allowed it to stay in a battle long after a Hive-Ship would have succumbed, and ''Daedalus'' has held its own in battle against the Wraith (sometimes against multiple Hive-Ships) and has scored numerous kills against the larger vessels.
''Odyssey''
The second USAF production spacecraft of the ''Daedalus'' class battlecruiser is called the USS ''Odyssey''. Its design, weapons, and technological capabilities are identical to the ''Daedalus''; however, due to the use of the ZPM and changes made by Daniel Jackson, ''Odyssey'' is now capable of cloaking itself.[16] The Asgard make substantial technological upgrades to the ''Odyssey'' in the ''Stargate SG-1'' series finale, "Unending". The ''Odyssey'' is now equipped with the knowledge of the Asgard and various Asgard technologies, such as an Asgard power core.
After the destruction of the ''Prometheus'' in "Ethon", the ''Odyssey'' becomes the primary vessel in Earth's defensive fleet.
It is reported in the Atlantis episode "Echoes" (and confirmed in the ''Stargate SG-1'' episode "The Shroud") that one of the ZPMs left by the Asurans who invaded Atlantis is now powering the ''Odyssey'' to be used against the Ori.
Initial mission
During the shakedown cruise of the ''Odyssey'', the commander of the vessel, Colonel Emerson, is sent by General Landry to rescue SG-1. They have been captured by the Lucian Alliance on P6G-452 after the Stargate on the planet is taken by Ba'al, preventing them from dialing home.
The ship travels to the P6G-452 in hyperspace and is able to lock on to and beam SG-1 aboard using implanted identification chips that have been placed in all SGC personnel. The ship is then immediately contacted by General Landry to go and reclaim the Stargates from Ba'al's mothership. SG-1 beams aboard after Ba'al's ship is disabled and plants tracer beacons on all the Stargates and DHDs, while fending off Ba'al's Jaffa. A small fleet of Lucian Alliance Ha'tak vessels arrive and, ignoring the ''Odyssey's hails, attack Ba'al's ship. The ''Odyssey'' begins to fire on the Lucian ships with its railguns in order to prevent them from destroying Ba'al's ship while SG-1 is aboard. The ''Odyssey'' then manages to beam all but one Stargate and DHD before the Lucian ships destroy Ba'al's ''Ha'tak''. That particular Stargate is being used by SG-1 to gate back to Earth, but Colonel Emerson and the ''Odyssey'' assume the worst and retreat after the shields are nearly depleted with no significant damage done to the Lucian Alliance ships.
During the ''Odyssey''
"The Pegasus Project"
The ''Odyssey'' is dispatched to the Pegasus Galaxy in the ''Stargate SG-1'' episode "The Pegasus Project", in an attempt to create a stable wormhole between the Pegasus Galaxy 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 dialed into from another Galaxy, and there is insufficient energy produced by a standard Stargate to establish a connection. The ''Odyssey'' positions a Stargate near a black hole in the Pegasus Galaxy and using the black hole as the Stargate's power source, establish a connection with a Stargate that has been placed in close proximity to the Supergate. Once established, the ''Odyssey'' beams 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'' performs several unsuccessful attempts to jump the wormhole to the Supergate before a Wraith Hive-Ship detects the nuclear detonations and attacks the ''Odyssey''. Performing a slingshot maneuver around the black hole's gravity well, the ''Odyssey'' beams its remaining nuclear warheads into the Hive-Ship that is pursuing them just as it passes by the Stargate. When the weapons are detonated, the resulting detonation of both warheads plus the Hive-Ship sends 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 engulfs an Ori mothership, destroying it.
Lucian Alliance hijacking
With the possibility of another Ori Supergate in the Milky Way Galaxy, the ''Odyssey'' departs Earth to investigate in the ''Stargate SG-1'' episode, "Company of Thieves". On arrival, however, they are ambushed by several ''Ha'tak''-class vessels and are forced into a minefield, which, because their shields are weakened by a nearby neutron star, render the ship disabled. Soon boarded and seized, it is stated that their assailants are members of the Lucian Alliance who have been sent to destroy or capture the vessel. Demanding that Colonel 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 is repairing the ship, Carter attempts to stall the hijackers until an escape attempt can be made, an opportunity which affords itself when Daniel and Vala are likewise captured and brought to the ''Odyssey''. After retaking the ship and killing the leader of hijackers in the process, the crew returns the ''Odyssey'' to Earth for repairs. While the repairs are under-way, the ''Odyssey'' is fitted with a ZPM recovered after Atlantis had been retaken from the Asurans, after their occupation.[17]
Sangraal
The ''Odyssey'' is part of a plan to deliver Merlin's weapon to the Ori galaxy for the purposes of destroying the Ori outright. Daniel Jackson used his Prior abilities to take control of the ship and transport the crew safely to the surface. After bringing Jack O'Neill on board the ''Odyssey'', they set course for P3Y-229 while the ''Daedalus'' enters a parallel position over the Pegasus Galaxy Stargate that is maintaining the Supergate connection.
During the course of the trip, Jackson modified the ship's systems to generate a cloaking field, claiming "Having a ZPM helps". After the weapon is sent through the Supergate on an Ori ship and SG-1 had been evacuated with Asgard transporters, Jackson returns to his original form. Carter had a great deal of difficulty deactivating the cloaking device.
Other operations
Following the successful retrieval of Daniel Jackson from the Ori and the deployment of the Sangraal, command of the ''Odyssey'' is given to Colonel Davidson. Under his command, the ''Odyssey'' transports SG-1 to a planet being used by a group of rogue Jaffa under the command of Arkad as a base so that SG-1 could prevent Teal'c from killing Arkad.[18] Later, the ''Odyssey'' deploys ground-strike weaponry against a number of naqahdah filled cargo ships destined to be used against Earth by the rogue Jaffa in Arkad's army.9
''Odyssey'' is instrumental in the capture of Adria from a mothership under the command of Ba'al. The ''Odyssey'' utilizes the cloaking technology Daniel Jackson and Merlin installed in the vessel during the events of "The Shroud" and is used to hold Adria and prevent her escape using Anti-Prior technology. The Tok'ra are summoned to the ''Odyssey''
The Asgard legacy
''Odyssey'' attacks an Ori mothership
The ''Odyssey'' visits the Asgard home planet Orilla in the ''Stargate SG-1'' finale episode "Unending" at the behest of the Asgard. Thor explains that the Asgard are giving humanity all of the knowledge of the Asgard, as a disease they have contracted is causing their bodies to degrade rapidly; consequently, the Asgard will soon become extinct. As the Asgard finish the upgrades to the ''Odyssey'', several Ori motherships exit hyperspace nearby. The Asgard return to Orilla and as their last act destroy the planet, leaving the ''Odyssey'' as their legacy. Soon after the planet's destruction, the ''Odyssey'' has no choice but to fight, and, after a number of hits with its new Asgard weaponry, successfully destroys an Ori mothership.
''Korolev''
The ''Korolev'' is the third ''Daedalus'' class battle cruiser. Given to Russia by the USA in exchange for continued use of the Russian Stargate,2 it is under the command of Colonel Chekov.3 Just prior to the Battle of P3Y-229, ''Korolev'' is rushed to duty in order to defend against an invasion fleet of Ori motherships, though all major systems are complete and the ''Korolev'' is fully space worthy.
''Korolev'' carries a compliment of F-302's, having also acquired their plans in the Russian Stargate exchange. The ship is equipped with Asgard beaming technology, as demonstrated on Dr. Jackson and Col. Mitchell.
Six members of ''Korolev''
''Apollo''
''Apollo's Horizon missile platform deployed
The USS ''Apollo'' is a 304 commanded by Colonel Abe Ellis. It arrives at Atlantis with a weapons platform, code named Horizon, which contains six Mark IX "Gatebuster" warheads and 4 decoy warheads. In conjunction with the Atlantis team, Colonel Ellis and the ''Apollo'' successfully deploy the Horizon weapons platform against the Asuran homeworld, targeting key military sites where new warships are being constructed. They are successful in destroying all the Asuran vessels, along with most secondary targets.
Following the attack on the Asuran homeworld, ''Apollo'' returns to Lantean orbit. There it attempts to destroy a stripped down Asuran satellite-ship that arrives in orbit over the city containing a Stargate through which an energy beam is sent from the Asuran homeworld. The beam is momentarily turned on the ''Apollo'' immediately after it attempts to engage. The vessel's shields are heavily drained by the Asuran energy weapon. After that point Colonel Ellis pulls his ship back but remains in the vicinity of Atlantis. ''Apollo'' fires a number of missiles, but these prove ineffective against the satellite-ship's shields.
With no way for ''Apollo'' or Atlantis to disable the satellite-ship, a plan is devised by Doctor McKay and Colonel Sheppard to bring an asteroid from the area around Lantea, which they had previously assumed was left from a second, since destroyed, moon, into the path of the Asuran weapon long enough to allow Atlantis to fly to another world. F-302's, launched from ''Apollo's'' fighter bays under the command of Major Lorne, latch onto the asteroid and maneuver it from the system's debris field into the energy weapon's path. ''Apollo'' transports all non-essential personnel off the city just before the attempt to fly the city to another world begins. "First Strike" does not state if the ''Apollo'' enters hyperspace before Atlantis takes flight, or if the ship remains to monitor the satellite.
Bomb Bay
The ''Apollo'' is equipped with a bomb bay with an attached observation and control deck. From this bay, it can deliver such payloads as the Horizon Weapons System.8
Battle of P3Y-229
A ''Daedalus''-class ship absorbs fire
The season nine finale, "Camelot", sees the ''Odyssey'' and the ''Korolev'', 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-229.3 The Lucian Alliance ships are shown to arrive late into the battle. The Asgard vessel is an ''O'Neill'' class, piloted by the Asgard Kvasir. En route, the ''Korolev'' is ordered to collect SG-1 and report immediately to the Supergate. Their standing orders are 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 are far better at withstanding the opening attacks from the Ori vessels. Although the episode did not show the Asgard vessel being destroyed, it is seen fighting the Ori ships and taking numerous hits which appeared to be absorbed by its advanced shielding. However, as the engagement continues, both Earth vessels lost main power systems and main engines, rendering them "sitting ducks" to the Ori mothership's weapons.
Nearing the conclusion of the battle, with most of the vessels opposing the Ori destroyed, both ''Odyssey'' and ''Korolev'' remain largely intact (though incapable of continued combat), until two of the Ori vessels concentrated their fire on the ''Korolev'', cutting through the vessel's already failing shields before the ship explodes.
At least one F-302 from the ''Korolev'' survives its destruction and is retrieved by the ''Odyssey'' following the conclusion of the engagement. Only six members of the ''Korolev''
