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 and a
304, 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 Air Force and its allies on the two series.
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,
as was the case with the Prometheus.
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, which Samantha Carter describes as "truly amazing". In
addition, the Daedalus itself uses an Asgard engineer named
Hermiod, who is assigned to oversee integrated technology, until the
Asgard race commits suicide due to a genetic disorder.
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. These rings are compatible with rings onboard
Ori motherships as well as traditional
Goa'uld emplacements. When temporarily
genetically enhanced by Lantian technology, Rodney McKay wrote a formula on
how to enhance the shields on the Daedalus, it is unknown if it was
The Daedalus class carries numerous Mark III and
Mark VIII 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; only the
Odyssey has been seen with ventral hull emplacements. 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 Stargate Atlantis 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
intercepted 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.
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
mothership with several direct hits.
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.
The Daedalus' shields are also capable of standing up to multiple Wraith Hive-Ships or Goa'uld motherships in combat.
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
|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's succeeding commander is Colonel Davidson.
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 mothership's.
Appearing in the Stargate Atlantis season three finale, "First Strike", the Apollo, commanded by Colonel Abe Ellis, is used in a preemptive 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, the Daedalus is green, the Odyssey is orange, the Korolev is purple and the Apollo is Blue/Indigo.
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 until
Humans are entrusted to handle it on their own. 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.
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".
The Daedalus is launched from Earth after the
Zero Point Module is found in Egypt 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. 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.
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. 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.
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 "Camelot", 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 "The Pegasus Project", 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 dialed 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 maneuver 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
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.
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
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. 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.
The Asgard Legacy
The Korolev was a BC-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.
Assault on Asuran homeworld
The USS Apollo is a 304 commanded by Colonel Abe Ellis, and is later tasked to the second tactical wing. 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 Atlantis to another world begins.

|BATTLE OF P3Y-229|
|In the Season 9 finale, "Camelot", 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.
