Asgard starships
The starships of the Asgard are among the most advanced ever encountered by the SGC. All Asgard vessels in the series are depicted as being operated by only a single Asgard, although Thor makes a reference to evacuating his crew in "Nemesis". Mothership
An Asgard mothership, from "Small Victories". The Asgard mothership is the first type of Asgard vessel seen in the series. In "Thor's Chariot", the Beliskner is the ship of Thor, Supreme Commander of the Asgard Fleet. It appears near the end of the episode to remove the forces of the Goa'uld Heru'ur from Cimmeria. The Beliskner is destroyed in the third season episode "Nemesis", where SG-1 crashes it into Earth's ocean after it becomes infested with Replicators. Several ships of this type also appear in "Small Victories", some of which are controlled by the Replicators. Asgard motherships are equipped with intergalactic hyperdrives, two rear thrusters for sublight propulsion, and a forward-mounted deceleration drive to control planetary reentry. They are also equipped with Asgard beaming technology. The ship is powered by four neutrino ion generators. Armed with advanced energy weapons and protected by powerful shields, Asgard motherships can comfortably expect victory against Goa'uld Ha'taks even if outnumbered. However, Anubis develops enhanced shielding based on Ancient technology that is resistant to the mothership's weaponry. Asgard motherships utilize cloaking devices that render them invisible to radar, and have internal dampening fields that prevent explosives from detonating inside the ship. Each ship has automated medical treatment systems, including medical stasis pods that can be used in dire emergencies. There are advanced AI systems onboard that allow the ship to be operated by a single crew member, and the main computer stores all the collected knowledge of the Asgard. O'Neill-class vessel
 The O'Neill under construction, from "Small Victories" The O'Neill is the most advanced starship ever constructed by the Asgard, incorporating all of their latest technology, and is designed specifically to fight the Replicators. Its hull is composed of an alloy of trinium, carbon and naqahdah. Its armaments and defenses are substantially superior to earlier Asgard motherships. The O'Neill dwarfs the Earth-built Prometheus in size. It is equipped with intergalactic hyperdrives and beaming technology. The first ship of this type, the O'Neill, is named after Colonel Jack O'Neill of SG-1, in recognition of his actions on the behalf of the Asgard, particularly against the Replicators. The incomplete O'Neill is the Asgard's last hope against a Replicator invasion. However, Samantha Carter suggests instead using the O'Neill as bait to draw the Replicators away, giving the Asgard time to evacuate their civilization. The Replicators pursue the O'Neill into hyperspace, where their shields will not function, and are destroyed by the O'Neill's self-destruct. More O'Neill-type ships appear in later episodes; three ships of this type force Anubis to retreat in "Revelations", and six ships, led by the Valhalla, ambush Fifth's Replicator ship over Orilla. The last appearance of this ship is in battle against the Ori in "Camelot". The ship's fate is unknown, though its pilot Kvasir survived. Science vessel
The Asgard science vessel is first seen in "Fragile Balance", used by the renegade Asgard scientist Loki. Another ship of this type, the Daniel Jackson, is Thor's ship in "New Order". Due to a Replicator threat, Thor takes the Daniel Jackson to Earth for Jack O'Neill and the knowledge of the Ancients in his mind, from which he synthesizes a Replicator disruptor and incorporates it into the Daniel Jackson to eliminate all the Replicators on Orilla. Thor and the Daniel Jackson return in "Reckoning", to assist SG-1 during the Replicator invasion of the Milky Way. The ship is infested by Replicators, and Thor sends it into deep space to protect Earth before abandoning it. The science vessel is comparable in size to a Goa'uld Ha'tak. Like other Asgard vessels the ship is equipped with beaming technology, intergalactic hyperdrives, and shields, though they are ineffective against Replicator blocks. Minor ships
Pegasus Asgard vessel The Stargate Atlantis episodes "First Contact" and "The Lost Tribe" depict a splinter group of Asgard in the Pegasus galaxy willing to experiment on humans to solve their genetic deterioration. Their ships are hyperspace-capable, can pass through the Ancient shields of Atlantis, and are equipped with energy weapons. |
