This article provides a list of most fictional technology made use of in the television shows Stargate SG-1 and Stargate Atlantis.

Each race also has a main list with greater detail and completeness.

After five or more years of researching alien technologies discovered on offworld missions, along with billions of dollars of work, several prototype models, and several failures, Earth was eventually able to construct its first glider vessel based on alien technology. That was the X-301, an Earth/Alien hybrid (chiefly because of its Goa'uld Deathglider components), that ultimately failed, because of its alien components. After the failed flight tests, the Air Force decided to attempt to build an all human built craft, with components based upon what they learned from alien tech, rather than actually integrating actual alien tech into it. This was the F-302, a small 2-man space-faring ship much like a highly advanced MiG or F-22 Raptor. F-302s are now the standard dogfighting attacker used by Stargate Program militia.

It was not long before Earth too was able to create its first (and for a long time, only) interstellar battlecruiser, the Prometheus. Whilst the F-302 is generally sufficient to successfully challenge its alien equivalent, the Prometheus was still far inferior to the highest class of battlecruiser owned by most other prominent races in the galaxy. Later, with the assistance of the Asgard, Earth was able to create a more advanced class of ship, the Daedalus-class Deep Space Carrier.

F-302: The standard interceptor used by U.S. Space Forces. It is space-capable and even hyperspace-capable for short distances (This is generally considered a failed system, and probably disabled in most F-302's. Also to accomplish that feat, it requires an amount of Naquadria to power the hyperdrive, which most fighters are unlikely to have because of the rarity and expense of the element). It carries modified air weapons. A large wing of these defended Earth against the fleets of Anubis in the season 7 finale, "Lost City", and was the first time that such attack was attempted.

BC-303 ''Prometheus'' Battlecruiser: The first experimental combatant ship produced as an Earth/alien-hybrid, designed to combat Goa'uld motherships such as the Ha'tak. The Prometheus uses missiles as primary weapons. The Prometheus was destroyed in Season 9. No more Prometheus-class vessels have been constructed in favor of the new Daedalus-class Battlecruiser.

BC-304 ''Daedalus''-class Battlecruiser: Earth's second-generation line of starships; the first ship of its class was named the Daedalus after Daedalus, the engineer and architect of Ancient Greek mythology. Much later, the second ship of the class was named the Odyssey with the registry number of 'PB3865' (first seen in 'Off the Grid'), after the Homeric poem of that name. The third, constructed only by the end of Season 9, was the Korolev, most likely named after Sergey Pavlovich Korolev, the Soviet Union's chief rocket engineer during the space race, between the U.S. and the U.S.S.R. In the Season 9 finale the Korolev was destroyed. Also, in the Season 3 finale of Stargate Atlantis, a new ship will be added called the Apollo. It is unknown if it is a Daedalus class battlecruiser or not.This class of starship is a significant improvement over the Prometheus design. It has a sleeker shape and a larger, more powerful array of engines than its predecessor. Its weaponry includes rail guns, dorsal tube-launched missiles, tactical nuclear weapons, and a cargo bay with a unit of F-302s. The biggest difference in the BC-304's design is its abandonment of much of the Goa'uld technology in favor of Asgard technology, including shields, sensors, beam technology, hyperdrive engine, and (at least in the case of the Daedalus,) an actual Asgard controlling the finer points of the ships operation. However, these ships still possess Ring Transports, which is in fact Ancient technology, rather than Goa'uld as was originally assumed.

The Mobile Analytic Laboratory Probe (MALP) is a remote-controlled, wheeled, robotic probe, used to explore alien planets without endangering SGC personnel. One is always sent through a gate first, if the planet is unexplored. MALPs contain equipment used to determine such things as the breathability of the atmosphere and the presence of a working DHD on a planet to be explored. The camera equipment allows video, including videoconferencing, between Earth and off-world SG teams.

A metallic barrier that can open and close over the Stargate, which blocks incoming traffic through the Stargate when closed; developed to prevent incoming hostile alien races, or weapons from reaching Earth. This is achieved by preventing molecular reintergration and reconstruction due to the close proximity of the Iris to the Event Horizon of the Stargate. The original Iris was made of pure titanium. Later versions of the Iris were made of a Titanium/Trinium composite (Primarily after the SGC accidentally dialed to a planet that was being pulled into a black hole, which pulled the original Iris into the gate). Trinium is not found on Earth, and so must be mined at offworld mining sites. The Iris can only be opened or closed by either a handprint detection device usually operated by one of the Gate Technicians, or a manual lever located in the Gateroom used primarily in case of emergencies such as a power outage at the SGC with a simultaneous incoming wormhole. SGC operationing procedures dictate that the Iris is closed for all incoming traffic, unless first identified by means of a special IDC transmitted by a device nicknamed the 'GDO' (Garage Door Opener). This ensures that only known friendlies are allowed safe arrival to Earth. On rare occaisons (and against SGC regulations), the commanding officer present has allowed entrance based on Radio communications alone. The Iris has never actually been breached by hostile forces while closed, although it did come close on one occasion by the attempt of a Goa'uld using a particle accelerator to melt through it. On the other hand, the Iris has been circumvented by aliens on more than one occaison (Thor, for example, managed to remotely disable the Iris before it was closed, and the Tollan appeared to do the same to allow the Nox to rescue them from Earth in the episode Enigma), but it has never actually been penetrated with the single exception of the friendly Tollan, Nerim, who used a Tollan Phase Shifting device to allow him to walk through the Iris, without actually damaging it.

The Asgard are both the founders of the Norse mythology (posing as Gods for benign purposes) and the accidental founders of the Roswell incident (which involved crashed Asgard). They possess a considerably higher level of technology than the Goa'uld, and are contempories of the Ancients. Their ships are capable of traversing thousands of light years of space in minutes, and are capable of operating with as few as one Asgard on board, suggesting that their ships possess highly advanced AI. They have also mastered advanced transporter and holographic projection technologies.

They do not reproduce in the strictest sense; continuity as a species is maintained through a process of cloning and mind transferral, although this has resulted in a decay of the Asgard genome. While the Asgard maintain a large fleet of ships with defensive capabilities, as a whole they are not a militaristic race, and they strongly disapprove of the use of technology for aggressive purposes.

The Goa'uld were for the longest time the major power of the Milky Way, and held an evil tyranny. They are a strictly parasitic race. They rely on hosts for life, Jaffa for strength, and deception for power. Their technology is no different. The Goa'uld are scavengers, and their technology is a conglomeration of the discoveries and ingenuity of multiple races, including the Ancients. Very few items they claim as their own were actually invented by them.

All (or the vast majority) of their technology contains, in some form or another, naqahdah, the material of which the Stargates are constructed. This material also flows in Goa'uld veins, and is often used as a key to their technology, much like the ATA gene of the Ancients. The devices of the Goa'uld, it will be noted, are mostly warlike in nature, reflecting the megalomanic nature of the species.

The Ori are essentially the same race as the Ancients. However, the two groups split millions of years ago to avoid a war. Thus, the Ori's technology is as advanced as the Ancients. As a body, the Ori are completely Ascended, and they often use this to further enhance the effects of their technology. Overall, all of their efforts, including their technology, are for the purpose of garnering worshippers. For every person who donates his or her free will to the Ori, via an extremely complex metaphysical process, the Ori gain power, and hope to wipe out the Ancients.

The Wraith were the bane of the Ancients, a species that literally sucks the life out of humans for its food, thinks of humans as cattle, and "culls" planets for its "herd." They existed in vast numbers in the Pegasus Galaxy, and the two races were at war for centuries. Although Wraith technology is highly advanced it did not surpass that of the Ancients; according to the records in Atlantis, the Ancients won almost every battle with the Wraith, but due to the Wraith's simply massive numbers, they managed to cause the Ancients to fall back to Atlantis and eventually leave the Pegasus Galaxy altogether.
