• Timeline: Not a series summary as such; more a tracking of major events that have affected the program itself, and a way to keep track of which gate is where, when. I consider each season to be a calendar year. (See the note on the front page for details on timing.)
  • 0001 (or thereabouts): The stargate at Giza is buried. (Frozen) (Personal note: This is beyond absurd. We have extensive written records from the period, and people would have jotted down a note or two about hordes of godlike alien enslavers being thrown off the planet en masse by a widespread uprising of the downtrodden. Really.)
  • 1928: Dr. Langford discovers a stargate at a dig at Giza. (1969)
  • 1945: President Roosevelt orders tests done on the stargate to see if it could be used as a weapon. The experiments are headed by Professor Langford, Catherine's father. In January of that year, according to declassified documents from the Archives of the Joint Chiefs of Staff, gate activation occurred when Dr. Ernest Littlefield went through the gate to a destination later designated as P3X-972. After Ernest vanishes through the wormhole, the program is shut down. The gate is crated and sent to an armory, where the military could deny its existence. (Torment of Tantalus)
  • Late 1940s (post-WWII): Russian military takes a DHD away from the Germans, who had found it at Giza. They study it even without a gate to attach it to. (Watergate)
  • 1969: Time-travelling SG-1 hooks the gate up to a bunch of truck engines and creates a wormhole to send them back to their own time. (1969)
  • 1992 or 1993: After years of trying, Catherine Langford finally succeeds in petitioning the administration to reopen the project. The Stargate Project officially starts up as a secret project under Pentagon control, as they try to unlock the gate's secrets, under the command of General West. Some research is being done at Cheyenne Mountain with the gate itself, other research is being done at the Pentagon. Captain Samantha Carter is part of the Pentagon team. (Children of the Gods)
  • 1995: With the help of Dr. Daniel Jackson, the gate is opened and a team is sent through to Abydos -- Daniel, Colonel Jack O'Neill, Major Kawalsky, Major Ferretti, Lt. Brown, Lt. Freeman, Lt. Reilly, and Lt. Porro. After most of the survivors return home and declare the other end of the wormhole destroyed, the gate is covered with a tarp and the program is largely scrapped. (Stargate, the movie) (NB: I know the movie was 1994. This is fudging to make it fit with show canon, where Daniel -- who was recovered in early 1997 -- had been on Abydos for "over a year", but not two years. That puts the first Abydos mission in late 1995. Best I can do.)
  • 1996: General George Hammond replaces General West, assigned to oversee the secure shutdown of the program as his last act before retirement. (Children of the Gods)
  • 1997: The program is in the final stages of shutdown when Apophis comes through the gate and starts it back up again. Daniel is retrieved from Abydos and members of the SGC begin making regular trips through the gate, with Hammond remaining in command. The initial setup included nine teams, whose original (and continuing main) duties are to perform reconnassaince, determine threats, and if possible make contact with the peoples of the worlds they go to. The teams were to operate on a covert, top-secret basis, with only the Joint Chiefs and the president knowing of their existence. The initial briefing after Daniel was brought back from Aybdos was classified S.C.I. Top Secret. (Children of the Gods)
  • 1997: The stargate is covered with a retractable iris made of titanium, to prevent unwanted intruders. (Children of the Gods)
  • 1997: A presidential directive is issued to evaluate the scientific & cultural value of each mission -- ensuring that the SGC will never be a purely military operation. (Broca Divide)
  • 1997: A second stargate, complete with DHD, is discovered buried in Antarctica, and is retrieved and sent to Area 51 for storage. (Solitudes)
    • At some point soon after this, a research station is set up in the Antarctic at the site where the second gate was found. (Frozen)
  • 1997: Senator Kinsey cuts off all federal funding to the stargate, leaving Hammond with no choice but to shut the program down immediately (on orders from the president). This trapped Teal'c on Earth, despite his request to be allowed to leave to continue his fight against the Goa'uld. SG-1's actions -- against direct orders -- to stop Apophis' attack by ship despite the shutdown is enough to get the program reinstated. (Politics)
  • 1997: The SGC served as a command and control center for all USAF ops regarding the approaching Goa'uld ha'tak vessels. Had a link through AF SATCOM for encrypted communications to all AF bases and to NASA. (Within the Serpent's Grasp)
  • 1997: Alpha site is set up -- a planet that's held in reserve as a colony in the event of a catastrophic event or attack on Earth, meant to save the best and brightest of humanity (which translates into the best and brightest of US citizens who happen to have high clearances, and damned if I ever spotted anyone who looked remotely like a farmer in the group). (Within the Serpent's Grasp)
  • 1998: The second (Antarctic) stargate and the DHD are stolen from Area 51 and used to conduct a covert operation to gain as much technology as possible, with no regard to alliances or propriety. Once the program is shut down, the second gate is sealed again -- complete with welded-on solid cover -- and returned to storage at Area 51. No word on the DHD or where it went. (Touchstone) (NB: Four years after this aired, the audience was told that after a few successful times using it, the DHD simply died for no apparent cause -- presumably old age. [Frozen] This was the first mention of the DHD in that time.)
  • 1998: The Giza stargate (and the program) is nearly destroyed when it's inadvertantly connected to a black hole. (A Matter of Time)
  • 1998: The Giza stargate's iris is replaced with a new one, with trinium enhancing the titanium. (A Matter of Time)
  • 1999: The stargate program is nearly shut down when the Asgard negotiate a treaty with the Goa'uld that at first includes a section insisting that the Tau'ri stay on Earth. Only Goa'uld internecine squabbling saves the program. (Fair Game)
  • 1999: An alien incursion nearly succeeds in taking over the SGC, with aliens (disguised as Jack and Daniel using mimic devices) even getting offbase and across the country. (Foothold) Because of the seriousness of the security breach, all official records are purged of all info about it by presidential order. (Smoke and Mirrors)
  • 1999: The Giza gate is beamed aboard Thor's ship and used to transport SG-1 to safety, then crashes into the ocean along with Thor's rapidly exploding ship. (Nemesis)
  • 1999: The Antarctic gate is unsealed and installed at the SGC, to become the program's sole stargate. Hooked up to the computer, just like the original gate. (Nemesis/Small Victories)
  • 2000: The Russians salvage the Giza gate from the ocean's floor and begin their own stargate program, using the Giza DHD to dial addresses. The program is active for more than a month before the SGC finds out about it, and is then shut down. The Russians retain control of the Giza gate and DHD, but agree not to use them. (Watergate)
  • 2000: Hammond retires (ostensibly of his own free will, actually because he's being blackmailed into doing so), and is replaced with General Bauer. After some fairly disastrous proceedings (during which Bauer nearly blows up the entire planet) and some serious string-pulling by Jack to get Hammond clear of his blackmailers, Bauer is relieved of command and Hammond is reinstated. (Chain Reaction)
  • 2001: To save Teal'c's life, the SGC requests, and receives, a loan of the Giza DHD from the Russians. The process used to save Teal'c creates an energy backlash that destroys the DHD. (48 Hours) (NB: When this episode aired, there had been no mention of the Antarctic DHD since Touchstone aired (1998); to all appearances, it had been shipped back to Area 51 and totally forgotten about. It's not until the season after 48 Hours that the audience finds out the Antarctic DHD failed after only a few uses.)
  • 2002: Antarctic gate, locked open and rapidly building up dangerous levels of energy due to an attack by Anubis, is removed and sent through a wormhole, and explodes 3 million miles away from Earth. The program is shut down completely for a brief period to prevent a repetition of the attack, then re-opened when Teal'c arrives via cargo ship and announces that Anubis' weapon has been destroyed. The Giza gate is rented from the Russians and lowered down to take its place, and once again becomes the SGC's only stargate. (Redemption, part 2)
  • 2002: Approximately three and a half months elapse between the events of Shadowplay and Sight Unseen (in the latter, Jack says it's been "more than three months" since Jonas got a clean bill of health regarding his naquadria exposure; that exam happened in Shadowplay) (Sight Unseen)
  • 2002: The SGC discovers that there's another dimension co-existing with ours, apparently inhabited entirely by bugs of one sort or another, which can be seen with the aid of an Ancient device. Colorado Springs is quarantined (with a cover story of a chemical spill that's causing hallucinations in anyone exposed) while the SGC deals with the problem. (Sight Unseen)
  • 2002: A Goa'uld ha'tak vessel (Anubis' abandoned ship) crashes into the Pacific ocean and explodes through an auto-destruct. Thor's consciousness had been trapped on the ship, but SG-1 safely removes it and returns him to his people to be transferred into a new clone body. (Descent) The Russians concoct a cover story with the Americans to explain the explosion to the rest of the world: one of their missile subs, the Rostov, was only 75 kilometers away from a "meteor" that struck the ocean, and was so badly damaged by the shockwave that it sank to the bottom. Before the deep-submergible rescue vehicle sent from Pearl Harbor ("in the spirit of international cooperation") could reach it, its reactor went critical, and it exploded. (Disclosure)
  • 2002: The stargate program is disclosed, in full (as far as I can tell) to the governments of Great Britain, France, and China (along with the US and Russia, they make up the five permanent members of the UN Security Council). None of these governments had believed the cover stories put forth by the US and Russia for various events, but none of the ambassadors was initially prepared to believe the truth. (Disclosure)
  • 2002: The Prometheus (X-303) goes out on its shakedown mission. Everything works properly, but due to an unexpected passage through intense gravity waves while in hyperspace, part of the machinery failed, and the reactor had to be jettisoned. The ship landed on a planet with a stargate, and presumably a replacement reactor was sent through and installed so the ship could return home. (Memento)
• A team, including Dr. Catherine Langford, Dr. Gary Meyers (who did the initial, incorrect, translation on the stargate's capstone) and Barbara Shore at the stargate facility, and Dr. Sam Carter at the Pentagon, spent two years trying to make the stargate work. Catherine brought Daniel in on the project when he was at his rope's end; he immediately retranslated (correctly) the capstone (correct translation: "A million years into the sky is Ra, the Sun God, sealed and buried for all time, his Stargate.") and within two weeks had figured out what the symbols in the center of the capstone (and on the stargate itself) really meant, and the gate was activated. (Stargate the movie)
• First mission to Abydos included Colonel O'Neill, Major Kawalsky, Major Ferretti, Lt. Brown, Lt. Freeman, Lt. Reilly, and Lt. Porro (Stargate the movie)
• The Seeker project was being discussed/initiated (unclear whether it was still just on the drawing table or if it was being implemented) as a way to detect a Goa'uld ship's "footprint" along the path taken by Apophis' ships to reach and attack Earth. (Apparently working on the assumption that that particular corridor of space is the most direct route to Goa'uld-occupied space, and thus the most likely approach vector for more Goa'uld ships.) Although it's not made completely explicit, the implication was that Sam wanted to use P5C-629, a planet within that corridor, as a platform to do this observing/detecting. (Thor's Chariot)
• Unconfirmed: A secondary SGC base was to be established offworld as a backup, with O'Neill in command, but the Pentagon didn't grant the backing. Very possibly just part of Jack's cover story. (Shades of Grey) Jack was definitely supposed to take command of the alpha site in the event SG-1 couldn't prevent an asteroid from destroying Earth. (Failsafe)
• Teams: The SGC began with nine teams (Children of the Gods), then expanded to twelve (In the Line of Duty), then to fifteen (Into the Fire). As of Ascension, it's up to at least sixteen teams. As of Proving Ground, it's up to at least seventeen teams. As of Metamorphosis, a Russian team has been operating as part of the SGC for a while. See SG units for details.
• Considered setting up a permanent research station on MC4-862 (a moon orbiting a gas giant), but after six weeks of uneventful existence, the scientists there were attacked by tiny glowy energy beings and forced to abandon everything. (Prodigy)
• The Groom Lake Facility in the Nevada desert at Nellis, known as Area 51, is where all technology brought back through the gate is sent for study, including the notes from "Heliopolis" and the two death gliders. Colonel Maybourne was reassigned there in 1998. (Touchstone)
• Four NID men escaped through the second gate to an unknown location. (Touchstone) They were later found and arrested. (Shades of Grey)
• Research station in the Antarctic (White Rock Research Station), established after the second gate was found. The Pentagon re-evaluates their presence every year. (Frozen)
  • Headed by Dr. Michaels, and included Drs. Woods and Osbourne. (Frozen)
  • Facility housed a research lab, observation room, and quarantine room, along with quarters (bunkbeds), a rec room, and storage rooms. (Frozen)
  • The team dug up the two Jaffa stuck in the ice when they arrived. In four years of looking after that, they found nothing until finally discovering "Ayiana" -- a (very) humanoid female who was effectively in cryogenic stasis for several million years. (Frozen)
• Acquired a substantial supply of naquadria when SG-1 took a stolen cache from Kelowna. (Shadowplay)
• The entire program was disclosed in 2002, apparently in full, to the ambassadors to the US of Great Britain, France, and China (together with the US and Russia, these countries make up the five permanent members of the UN Security Council). (Disclosure)
  • Hammond and Major Davis were the US military representatives; Kinsey showed up as the US political representative; Colonel Chekhov was the Russian representative. (Disclosure)
  • Prior to the disclosure, none of these countries had come close to figuring out what was really going on, despite not believing any of the cover stories being put forth by the US or Russia.(Disclosure)
  • The reasons for the disclosure were not adequately explained, at all [nb: personal opinion, obviously] -- Earth was not in especially imminent, or greater-than-usual, danger from anyone when this meeting was called and held. The only reason given was that the Chinese government had threatened to air evidence disproving one of the US's cover stories -- but that's hardly enough reason to go (relatively) public with the program after so many years of successful secrecy. All the evidence would prove was that it was a cover story for something, not give away what was being covered for. (Disclosure)
    • Much of the push for disclosure seemed to be coming from Kinsey, but it's unclear how he could be in a position to force this.
  • The Chinese ambassador was the first to announce that Hammond's reasons for insisting on secrecy were insufficient for him, and attempted to leave to inform his people of what was going on. He said the only way he'd accept the deal would be if control were taken away from the US military (he was not happy to find about the X-302 and X-303 already being in US control).
  • When the Chinese ambassador objected -- rather strongly -- to the stargate program remaining under US military control, the French ambassador suggested moving the stargate to a neutral location and creating a permanent staff drawn from all five regions -- Hammond refused. (Disclosure)
  • Before everything could fall completely Kinsey's way, Hammond's trump card showed up: Thor transported in and chatted for a few minutes about how the SGC, Hammond, and Jack O'Neill were good friends to the Asgard, and how it was "preferred" -- although not necessary -- that the SGC stay under the same control. The ambassadors were quite impressed, and agreed to leave Hammond in command, with the SGC remaining at Cheyenne Mountain. (Disclosure)

With thanks for some of this to the official MGM Stargate FAQ, at http://www.stargate-sg1.com/home/faq/index.html. Any non-Stargate-specific terms are from the DOD Dictionary of Military Terms, at http://www.dtic.mil/doctrine/jel/doddict/, and the official DOD Dictionary (http://www.dtic.mil/doctrine/jel/new_pubs/jp1_02.pdf).

• DHD: Dial Home Device. The standard device connected to a stargate, covered in two concentric circles of symbols, with a central crystal. Pushing the right symbols in the right sequence, then the central cyrstal, activates the stargate. Without a DHD, travel is impossible unless a substitute is found (like the SGC's dialing computer), or unless the gate is hooked up to an external power source and the inside track is moved manually. (picture, with thanks to the old stargatesg-1.com site; I don't think this picture is still up on the new, non-Showtime site at the same URL.)
• FRED: Field Remote Expeditionary Device. The small, six-wheeled, remote-controlled truck that carries supplies for field units on missions.
• GDO: Garage Door Opener. The device all SG members carry strapped to their arms, from which they can transmit a signal to send through an open wormhole to let the SGC know it's safe to open the iris. (picture -- thanks, K!)
• MALP: Mobile Analytic Laboratory Probe. This is sent through the stargate prior to every mission, to get information on local conditions. It also provides a camera and radio, through which the SG teams can communicate visually with the SGC.
  • MALPs have infrared cameras as part of their standard equipment. (Within the Serpent's Grasp, Touchstone)
• MOPP: mission-oriented protective posture. This is usually followed by a number, indicating the level of protection (protective gear) being used.
  • From the official DOD dictionary (http://www.dtic.mil/doctrine/jel/new_pubs/jp1_02.pdf)
    • mission-oriented protective posture — A flexible system of protection against nuclear, biological, and chemicalcontamination. This posture requires personnel to wear only that protective clothing and equipment (mission-oriented protective posture gear) appropriate to the threat level, work rate imposed by the mission, temperature, and humidity. Also called MOPP. See also mission-oriented protective posture gear. (JP 3-11)
    • mission-oriented protective posture gear — Military term for individual protective equipment including suit, boots, gloves, mask with hood, first aid treatments, and decontamination kits issued to soldiers. Also called MOPP gear. See also decontamination; mission-oriented protective posture. (JP 3-11)
• SF: security forces; single frequency; special forces. In Stargate's case, where it's used for the guards on base, it likely means "security forces".
• TER: Transphase Eradication Rod: detects objects operating in the light spectrum 180 degrees out of phase of human vision, like the alien race the Reetou.

General info

• Stargate Command (SGC) is located at the Cheyenne Mountain Complex in Colorado.
• The SGC has the ability/equipment to set up portable decontamination chambers. (Singularity)
• The SGC can set up a decontam spray right in front of the stargate, to catch anyone coming through, and decontamination chambers around the doors into the gateroom to keep infection from spreading outward. (Singularity)
• Nearest town is Colorado Springs. (multiple eps)
• There's an abandoned nuclear facility just 20 minutes away from the SGC, where Hammond sent SG-1 and Cassandra, when Cassie had a bomb inside her chest that they couldn't figure out how to turn off. They brought her down into Storage Facility No. 68, into a chamber 30 stories underground through solid rock. (Singularity)
• One local paper is The Gazette. (Desperate Measures)
• Internal phone extensions have four digits. (Absolute Power)
• Red alert buttons scattered all over the place, within easy reach of anyone at any time. (multiple eps)
• Emergency cutoff switch for the gate's power in the gateroom itself added by Entity.
• Uses AF SatCom to bounce radio signals from teams in space. (Failsafe)

Physical layout:

• Access:
  • Main access is through Norad, which is on the main level.
  • Access shaft running from surface straight down to Level 28, possibly with no ladder; Major Cromwell and his team were ready with ropes to go down it. Surface hatch has no lock (but is possibly guarded), and is located in a woody area but next to a concrete shed (use unknown). Within the SGC, the hatch on 28 was bolted shut; Cromwell had to burn through the locks to get out of the shaft. (A Matter of Time)
  • Second (?) direct external access shaft to the surface, with the surface hatch located in a completely wooded area. (If it's the same shaft Cromwell used, they've torn down the shed and let the area get overgrown.) The surface hatch is unguarded and has no locks of any sort on it (this is a security *nightmare*). Sam accesses the shaft on Level 16 via hatch: LV 16 / 28842 (unbolting it to gain access). The hatch has no internal indicator of what floor it exits onto, and there's no way to tell if it goes any deeper than Level 16 since she later returns to that level via the same shaft. (Foothold)
  • Third access shaft? Surface access hatch requires a five-digit code (on a keypad) to get in; tear gas is released if the wrong code is entered. Jack and his trainees exit the hatch (and the trainees later re-enter it to move around the SGC undetected) on Level 19 via hatch: LV 19 / 28841 (burning through the bolts to open the hatch from the inside). (Proving Ground)
    • The number is just barely different than the one on the shaft Sam used in Foothold. If this is the same shaft (with the different final number possibly indicating the deeper level of access, rather than a different shaft location), the surface lock was added after Sam's easy access to the SGC in Foothold.
• Supply of tranquilizer guns in lockup C -- no idea what floor. (Hathor)
• Original base-wide locker room was room 214 B; included a jacuzzi (possibly 214B was simply the jacuzzi/whirlpool room; no sign of actual lockers). (Hathor)
• SGC on sublevels (all are actually Level S-#; the higher the number, the lower the floor). Hallways have card-key readers at every section; possible to use the keys to close and lock the blast doors between sections.
• It's possible that cardkeys are required to access the elevators on all levels; it's definitely true of levels 19 and 21. (Full Circle, Rite of Passage)
• Medical facilities include:
  • Infirmary (Level 21)
  • Labs (Levels 19 and 21)
    • One of the medical rooms (not the main infirmary, nor Fraiser's office), where Janet brought Hammond and Jonas to look at MRI scans on a lightboard, had a monitor connected to a security camera in the hallway, tracking everyone who came down the hallway to the room. (Prophecy)
  • Isolation rooms (Levels 19 and 21)
  • Operating rooms
  • MRI equipment
• Key areas (information is replicated below in a bit more detail, under Levels):
  • Accounting: Level 3
  • Archives: Level 24 (probably)
  • Armories: Level 19, Level 28
  • Briefing room: Level 27
  • Daniel's office: Level 18
  • Gateroom: Level 28
  • Hammond's office: Level 27
  • Holding cells, secure: Level 16
  • Infirmary: Level 21
  • Isolation quarters (not secure holding cells): Level 22
  • MALP storage: Level 24
  • Medical labs: Levels 19 and 21
  • Monitoring station: Level 16
  • Sam's office (lab): Level 21 as of third season; Level 19 thereafter
  • SG-1's locker room: Level 25
  • Teal'c's quarters: Level 25
  • VIP quarters: Level 25

    • Holding cells have both a card-key lock and a standard lock in the door. (Rite of Passage)
• Level 17: a storage room (12-A) on level 17 was converted into a meeting room for the negotiations between the Asgard and the Goa'uld in Fair Game
• Level 18: Offices (Serpent's Venom -- on their way up to the surface, Jack, Sam, and Jacob stop on Level 18 to pick up Daniel, who's got bags of research material with him).

• Level 20:
• Level 21:
  • Infirmary (Entity).
  • Fraiser's office (Rite of Passage)
  • Sam's lab (Learning Curve). (This is possibly her first lab, and she later moved to Level 19; there's no further evidence that she has a lab on 21 [if someone has any evidence that I'm wrong, please let me know!])
  • At least one shielded isolation room (off corridors J-3 and J-5); used to keep Cassie's fluctuating EM field from wreaking havoc on base electronics (Rite of Passage).
  • Lab/holding room between doors M-4 and M-6 -- the exterior portion of door M-4 says M-5). There's a glassed-in, slightly elevated observation room at one end, clearly visible to the room's occupants. (The Menace)

• Level 22:
  • Isolation quarters (Urgo)
  • Isolation room 3 (Metamorphosis)
  • Cafeteria (Unnatural Selection)
• Level 23: Where the aliens stored all the humans they were impersonating (Foothold)

• Set up in 1997. (Within the Serpent's Grasp)
• Planetary designation/address is P3X-984. (Serpent's Lair)
• The first time the site is used, at least 13 teams of people are sent through the gate. (Serpent's Lair)
• A planet that's held in reserve as a colony in the event of a catastrophic event or attack on Earth, meant to save the best and brightest of humanity (which translates into the best and brightest of US citizens who happen to have high clearances, and damned if I ever spotted anyone who looked remotely like a farmer in the group). (Within the Serpent's Grasp)
• Chosen because the address is unknown to the Goa'uld. (Allegiance)
• Has an infirmary. (Allegiance)
• Has at least one holding cell, complete with bars. (Why? Bizarre thing to build into an emergency, let's save the entire human race facility that's designed to hold only hand-picked people.) (Allegiance)
• Was put into use as a place for the rebel Jaffa army to stay, after Cal Mah was destroyed by Yu. (Allegiance)
• Jacob knows the address, but no other Tok'ra does. (Allegiance)

Originally, the SG teams were known only to the President & Joint Chiefs (Children of the Gods). This soon changed:

• Politics -- Senator Kinsey has been fully briefed. When he started asking questions about the line item for the unofficial project called Area 52, the president and the joint chiefs decided that if he were granted access to the project, he might recognize its importance and agree to support it. (The plan pretty horribly backfired...) After reading all the mission reports and being briefed vy Samuels, Kinsey decided to cut off all funding. (The SGC could have circumvented this by opening a discussion on the Senate floor, but that would have meant exposing the program to the public, and the president and joint chiefs didn't want to do that.) (Politics)
• In the Serpent's Lair -- Dozens of people (at least 13 teams -- unknown how many people on each team) are brought in and sent through the stargate to the alpha site; all of them are now aware of the program. In addition, the shuttle Endeavor picks up Jack, Sam, Teal'c, and Bra'tac, and ferries them home. At least the astronauts, and possibly the entire ground crew, know what's going on.
• Secrets -- undisclosed leak to media; Hammond assumes that if Kinsey knows, his aides do. Not canon that they do know, therefore, but important because the SGC is assuming that (an indeterminate number of) other people know.
• A Matter of Time -- outside units being briefed and brought in.
• Touchstone -- Area 51, where it's very clear that these non-SGC personnel (military researchers) know about the SGC and the SG teams, know what they're doing and where they're going, and what they're bringing back (working on death gliders, medical advances, etc.).
• Watergate -- a whole bunch of Russian scientists (and certainly government, and presumably military personnel) know all about the SGC, including mission reports and team profiles.
• Tangent -- Gen. Vidrine knows everything about them, and can't possibly be one of the joint chiefs because he's only got three stars.
• Point of No Return -- Martin, a civilian, knows way too much about the SGC and the stargate, including knowing Jack by name; says he found out about it on an online conspiracy chatroom.
• Entity -- an Academy cadet is brought in and not only told about the program but sent to a research facility on a moon (and introduced to Teal'c, who admits he's not exactly human), all to give her incentive to stay in the Air Force.
• Exodus -- Jack tells Jacob that there are a thousand engineers and scientists drooling to get their hands on the mothership SG-1 stole from Cronus.
• Ascension -- the Pentagon sets up surveillance on Sam.
• Red Sky -- Dr. MacLaran is given a tour of the SGC, including the gateroom, in return for giving up the superheavy element he'd spent the last five years creating.
• The Tomb -- a Russian team of four are brought into the SGC for a mission; only one survives, but she is debriefed at the SGC by one of her Russian superiors.
• Desperate Measures -- massive amounts of information have leaked to a private corporation, which has the contacts to actually purchase a symbiote that was trapped on Earth and use it to try to cure the corporations incurably ill president.
• Proving Ground -- the commander of the nearby Air Force Academy, General Kerrigan (who as of fourth-season Prodigy had known nothing about the SGC), is an active part of the recruitment program, and watches training sessions with Hammond (making bets on the outcome...).
• Failsafe -- SG-1 is sending uncoded radio signals via AF SatCom (for any AF radio operator to pick up? I don't know enough about how SatCom works), and NASA is tracking their progress in getting up close and personal to destroy the asteroid, and giving SGC updated status reports on the mission.
• Prometheus -- Julia Donovan (tv reporter for "Inside Access") and Hal (Julia's producer) were leaked some information by the NID (e.g., a sample of naquadah, and at least the beginnings of the money trail), and push until they're allowed to actually visit "Prometheus" -- the nearly complete X-303. The SGC was planning to doublecross them by confiscating and destroying all tapes and notes, leaving them no proof. Hal had been bribed by the NID, and the camera crew was made up of rogue NID members, who hijacked the X-303 as soon as they got aboard. Hal wound up dead; the rest were captured after the ship made it into space. Donovan wound up going with SG-1 to help the Asgard just because she was on the ship when Thor appeared and asked, and there was no way to go home first. No idea if anyone outside her camera crew and Hal knew anything about her story lead, but it's possible.
  • No idea what happened to her; she was transported off the X-303 and into the cafeteria kitchen on Level 22 when Thor arrived at the ship to get Jack and the others. (Unnatural Selection)
• Disclosure -- high-ranking politicians/diplomats from France, Great Britain, and China.
  • The Chinese ambassador to the US, along with at least the Premier, and possibly other ranking members of the government, after a meeting with Hammond, Maj. Davis, Kinsey, Col. Chekhov, and the ambassadors-to-the-US of France and the UK in which all was explained. (The United States, China, Russia, France, and the United Kingdom are the five permanent members of the UN Security Council.) The Chinese ambassador was the first to announce that Hammond's reasons were insufficient for him, and attempt to leave to inform his people of what was going on. He said the only way he'd accept the deal would be if control were taken away from the US military (he was not happy to find about the X-302 and X-303 already being in US control). (Disclosure)
  • The U.K. ambassador to the US, along with at least the Prime Minister, and possibly other ranking members of the government, after a meeting with Hammond, Maj. Davis, Kinsey, Col. Chekhov, and the ambassadors-to-the-US of France and China in which all was explained. (The United States, China, Russia, France, and the United Kingdom are the five permanent members of the UN Security Council.) (Disclosure)
  • The French ambassador to the US, along with at least the President, and possibly other ranking members of the government, after a meeting with Hammond, Maj. Davis, Kinsey, Col. Chekhov, and the ambassadors-to-the-US of China and the UK in which all was explained. (The United States, China, Russia, France, and the United Kingdom are the five permanent members of the UN Security Council.) When the Chinese ambassador objected -- rather strongly -- to the stargate program remaining under US military control, the French ambassador suggested moving the stargate to a neutral location and creating a permanent staff drawn from all five regions -- Hammond refused. (Disclosure)
• Memento -- Vandenburg AFB (gave the okay for the Prometheus to open a hyperspace window on its shakedown cruise)
• Prophecy -- Dr. Sandy Van Densen, a neurosurgeon called in by Fraiser to conduct the surgery on Jonas to remove the "tumor" that was causing him to be precognitive.
• So, therefore, the original level of secrecy only lasted a very short time, and as the program goes, it gets known to more people. With every passing year, it gets more dangerous.

• Nicholas (Nick) Ballard: Daniel's maternal grandfather. (Crystal Skull)
  • Dutch, but living in the US for at least 20 years between the late 1970s and the late 1990s, and probably before then as well. Although he could have done so, he chose not to adopt Daniel when Daniel's parents died in 1973, presumably at least in part because he was too caught up in his own obsession. (Crystal Skull)
  • Like his daughter, son-in-law, and grandson, he was an archaeologist. (Crystal Skull)
  • In 1971 he discovered a crystal skull in a ruined temple in Belize, which transported him to an alien world where he found "giant aliens" who rose up like mist to greet him. When he was transported back to the temple, it collapsed around him, and he barely escaped. (Crystal Skull)
  • The academic community drove him out when he explained his theory that gazing into the eyes of the crystal skull would transport a person to see aliens (like grandfather, like grandson). (Crystal Skull)
  • A few years later, he suffered a mental breakdown and checked himself into a psychiatric institute in Oregon, where he stayed for 20 years, suffering a variety of hallucinations. Daniel was a regular visitor until right before he joined the Stargate program, when they had a falling out. Daniel couldn't buy Nick's theories about the giant aliens, and Nick thought Daniel was as insane as he was for thinking the pyramids were landing platforms for alien spaceships. (Crystal Skull)
  • In 1999, Daniel was trapped out-of-phase from looking into a crystal skull, and the rest of SG-1 went to ask Nick for help. In return, he demanded access to the skull they'd found. Possibly due to his experience with the skull, he could see the out-of-phase Daniel, and the two reconciled. To help rescue Daniel, Nick insisted on going with SG-1 to the planet of the giant aliens, where he renewed his "acquaintaince" with Queztlcoatl and was invited to stay, so he could learn what the aliens had to teach. He accepted, and has been there ever since. (Crystal Skull)

• Cassandra (Cassie) Fraiser:
  • Born in 1985 (turns 16 in Rite of Passage [2001]; earlier references are hazier about her age, but Rite of Passage has her actual birthday celebration).
  • She was raised on the planet Hanka until she was about 12 years old, when Nirrti wiped out her entire people with a virus.
  • SG-1 brought her back to Earth. Tests run on her howed her clear of the infection that wiped out her people, but with naquadah in her blood. The naquadah later reformed inside her to create a bomb by pulling potassium out of her bloodstream, and causing cardiac arrest which Fraiser responded to by shocking her -- the electrical stimulus the bomb needed to activate. One side of the bomb was made up of naquadah, the other of iron and potassium. The sides were separated by a (decaying) layer of fatty tissue. (Singularity)
  • She bonded with Sam during that, but wound up being fostered/adopted by Janet Fraiser, although she also stayed close to Sam -- comforting Sam when she was depressed (In the Line of Duty), going boating with her and Janet on a weekend trip (Urgo), playing chess with her every other Saturday if Sam is onworld (Rite of Passage). Sam was also the only person other than Janet at Cassie's 16th birthday dinner. (Rite of Passage)
  • As of early second season, was still calling Janet "Janet", not "Mom". (In the Line of Duty)
  • Jack also maintained contact, enough that the kids from Cassie's first school on Earth still knew him the year after she left for her junior high (not middle school) (Learning Curve).
  • She has a dog (name unknown), given her by Jack because there's "a rule on Earth -- every kid has got to have a dog" (Singularity)
  • Her "cover story" for assimilating into Earth culture is that she was born in Toronto. (Singularity)
  • Cassie refers to the team by first names; calls Jack "Jack" in Rite of Passage.
  • In her very early teens, she liked art and had been told by her teacher that she had talent at it. (In the Line of Duty)
  • She has the ability to sense blended Goa'uld, presumably because of the naquadah still in her system. (In the Line of Duty)
  • At 15-turning-very-snotty-16 in high school, she was dating a boy named Dominic. (Rite of Passage)
  • She's been through a lot of trauma: she witnessed the deaths of her parents and all her people (Singularity); after Sam promised never to leave her, then to come right back when she actually left, she locked Cassie alone in a stone chamber with no explanation (Singularity); a goa'ulded Sam threatened her with death (In the Line of Duty); and she nearly died from a retro-virus that Nirrti had infected all of Cassie's people with, triggered at age 16. (Rite of Passage)
  • The virus caused her to generate a fluctuating, strong EM field, strong enough to disrupt electronic equipment and to make it impossible to give her an MRI. Eventually she could control the field, allowing her to manipulate things like magnets. To save her life, the effects had to be reversed, leaving her unable to manipulate EM fields anymore. She was saved by (a very grumpy) Nirrti. (Rite of Passage)

• Catherine Langford:
  • Born in 1924 (Torment of Tantalus -- she was 21 in 1945).
  • She's single (at least the last we heard), but was engaged to Ernest Littlefield as a young woman and reunited with him in her 70s. (Torment of Tantalus)
  • She has a PhD, probably in archaeology, and is very smart.
  • Her father was Professor Langford, an archaeologist who worked on the original stargate project.
  • After the original program was closed, she petitioned several administrations to reinstate the program, finally succeeding 40 years later. Began her 'gate research again in the late 1960s. (1969)
  • She recruited Daniel into the Stargate program in the mid-1990s (1994 by movie canon, 1995 by show canon), and knows Sam from Sam's Pentagon days.
  • She she left the program after the first mission to Abydos, and didn't find out what was going on with the SGC until The Torment of Tantalus when Daniel came to her asking about her father's records.
  • Her first and only trip through the stargate was to recover Ernest, whom she had believed was dead for the past fifty years. (Torment of Tantalus)
  • She has enough money to live in a great big house -- the same one she grew up in -- with a staff (at least a housekeeper), and to be chauferred around in a limo even after retirement. (Torment of Tantalus)
  • She's fluent in German, and seems fond of tea -- and has continued to use the same teaset she used as a young woman in the 1920s. (Torment of Tantalus, 1969)
  • She always wears a Ra pendant, for luck (Children of the Gods, Torment of Tantalus, There But for the Grace of God, 1969). She gave it to Daniel on the first Abydos mission, and Daniel gave it to Jack to give back to her when he decided to stay behind (Children of the Gods, Torment of Tantalus)

• Ernest Littlefield:
  • One of the archaeologists working on the original stargate project with Professor Langford. (Torment of Tantalus)
  • He figured out that the 39 symbols on the "doorway to heaven" weren't a combination lock, they were destinations. (Torment of Tantalus)
  • He was engaged to Catherine Langford in the 1920s, but as part of his work on the program he volunteered to go through the stargate, and was trapped offworld for fifty years on an abandoned world.(Torment of Tantalus)
  • He deciphered as much as he could of the alien languages he found there, staying remarkably sane for a human left completely alone for so long (barring a few hallucinations about Catherine). (Torment of Tantalus)
  • The planet he was on was close to Abydos (which is why he could travel there in 1945 without having to compensate for stellar drift), but not listed on the Abydos cartouche. (Torment of Tantalus)
  • He called the castle/fortress he'd been living in "Heliopolis" -- after the ancient Egyptian city that served as a repository of philosophy and astronomy, and a central place of worship for Ra. (Torment of Tantalus)
  • SG-1 and Catherine came to rescue him as soon as they found records of what had happened to them, and barely got him and themselves out in time as the building he was living in collapsed around them in a massive storm. (Torment of Tantalus)
  • He and Catherine seem to have rekindled their relationship, after a slightly bumpy start. (Torment of Tantalus)
  • No idea what's happened to him since then, although the odds are extremely high that he's staying away from crowds and is probably in more or less nonstop SGC-sponsored therapy.

• Training appears to have been mainly on-the-job for the first several years, but by 2001 (the year, not the ep) a more formal program was put in place, at least for recruits with no field experience.
  • Every few months, a small group is brought in and trained as a unit, with one as unit commander. (Proving Ground)
  • Training appears to include studying old mission reports; Lt. Elliot recognizes the name "Argos", knows that it was where Pelops was doing his rapid-aging experiments, knows about the nanotech involved, and knows how Jack was affected by it. (Proving Ground)
    • It's possible that the trainees were given a selection of mission reports that included information they'd need for their training tests, rather than being given access to all mission reports.
  • Field training consists of several days of obvious training excercises, in a training area, followed by a real-life-scenario that the trainees are unaware is a test, taking place at SGC and shutting down the use of several floors for the duration of the test. (Proving Ground)
  • Trainees are given intars to use. (Proving Ground)
  • The units are trained by a real SG team commander (with the help of his team). (Proving Ground)
    • SG commanders take training duty on a rotating basis, according to the trainees in Proving Ground. But SG-1 has clearly done this at least once before, and it seems unlikely that they've trained enough people to have rotated all the way through 17 SG commanders. It's possible that either SG-1 alone is responsible for the training sessions (at least while the program shakes out) or that a limited set of more experienced SG commanders and teams make up the rotation.
• The success of the program has prompted Hammond to decide to request funding for an offworld training facility in the next year's budget. (Proving Ground)

• Safety precautions within the SGC to avoid alien invasion or other problems:
  • Iris over the stargate to prevent anyone unauthorized from coming through (doesn't work against truly advanced races -- Tollans, Nox, Asgard, Ascendants can all circumvent this) (Children of the Gods, all eps since)
  • GDO (garage door opener) codes assigned to each team and ally, to let SGC know that it's okay to open the iris. No code, no authorization -- splat.
  • Hand scanners installed on dialing computer, so only recognized personnel can use the system (Foothold)
  • Emergency power cutoff switch in the gateroom, to shut down the stargate if it won't shut down on its own.
  • Aliens aren't allowed into the SGC without prior permission. (Unclear when this went into effect, since refugees have been brought back several times.) (Metamorphosis)
• Mission prep:
  • MALP sent through for info;
  • preliminary briefing to determine if mission is worthwhile;
  • physical checkup prior to mission (Ascension -- Sam mentions her pre-mission blood tests, and the fact that Fraiser cleared her for the mission).
• Screening: Returning teams have to go through progressively more thorough screening procedures as time goes on:
  • Visual and tactile examination of the back of the neck after The Enemy Within
  • MRI after In the Line of Duty
  • Blast of high-frequency sound after Foothold
• Several TERs were left with the SGC, and hand scanners were installed to prevent the Reetou from controlling the iris. (Show and Tell)
• Every SG team has a homing device to find the stargate if lost on a planet. (The Nox)

top | SGC

• SFs standing guard around the facility wear the Defensor Fortis patch: Defender of the Forces, the credo of the USAF Security Forces (The Menace)
• Standard weaponry:
  • Sidearm, either regular military issue (a Beretta, per The Sentinel) or zat.
  • Knife
  • P-90: carries 50-round top-loading magazine with teflon-coated ordinance, at a cyclical rate of 900 rounds per minute. (specs -- The Warrior)
  • (Not really a weapon, but SG members carry plastic restraints as part of their standard gear. (The First Ones, Forsaken))
• Plausible deniability:
  • The Air Force is allowing a television show called Wormhole X-Treme to be made, based entirely on the SGC, to allow them to use it as an explanation for any future leaks about the stargate program. (Wormhole X-Treme)
  • Sam told Julia Donovan that the X-303 was reverse engineered from an alien spaceship that crashed a hundred miles north of Fairbanks, Alaska in 1978. (Prometheus)
  • The cover story the Russians were giving (along with US officials) to explain the explosion of Anubis' crashed ha'tak vessel was that the missile sub Rostov was less than 75 kilometers from the impact of the "meteor" that fell into the Pacific, and was severely damaged by the shockwave; the sub sank to the bottom. The United States, in the spirit of international cooperation, sent a deep-submergence rescue vehicle from Pearl Harbor. Unfortunately, the Rostov's reactor went critical before the rescue vehicle arrived on the scene. (According to Chinese intelligence reports, the Rostov was taking on supplies at the harbor in Vladivostok when it supposedly exploded on the ocean floor. Whoops.) (Disclosure)
    • From all appearances, other governments didn't believe this or other cover stories, from either the Russians or the Americans, but none of them had figured out what was really going on -- just that clearly, the Americans were up to something, and the Russians were going along. (Disclosure)

top | SGC

• The stargate was lowered into the gateroom via a shaft that contains a crane. The shaft runs from from the surface all the way down to the gateroom, which has a retractable ceiling. The gate can be removed or replaced as needed. It takes two hours to hoist the stargate back out of the gateroom to the surface. (Redemption, part 2)
• The stargate is covered with a retractable iris.
• The stargate is controlled by computer, rather than DHD.
• At various times, the stargate being used by the SGC was the Giza or Antarctic gate. See timeline for details.
• Antarctic DHD: worked a few times after they dug it out, then just died and never worked again. (Frozen)
• Antarctic gate: possibly the oldest gate in the entire system, as much as 50 million years old. (Unfortunately, it's also been destroyed. See timeline.) (Frozen)
• Daniel apparently theorized that after the Giza gate was buried (timeline glitch: "roughly 2,000 years ago", which makes no sense, given the extensive written records we have from that time), the Goa'uld managed to open the buried Antarctic gate, because it was in a crevasse, which the wormhole made larger. (Frozen)

top | Stargates

• The iris is pure titanium (Children of the Gods) and is less than three micrometers from the event horizon -- matter can't fully reintegrate as a result (splat!). Like the Goa'uld, the SGC personnel have a homing device to find the stargate if separated from it. (The Nox)
• A new iris is added after the original one is sucked into the black hole in A Matter of Time, strengthened with trinium.
• The iris sits just in front of the plane where the event horizon is formed. Offsetting it just slightly would effectively stop a wormhole from forming -- like burying the gate. (48 Hours)
• The space between the wormhole and the iris is enough to allow high-energy subatomic particles to reintegrate, moving at near-light velocities (i.e., a particle accelerator can shoot particles at it from the other side). Modulating the particle stream can create an image, and intense heat, up to 130 degrees in the gateroom, and 6-8 times that for the iris itself. (Serpent's Song)

top | Stargates

• Earth doesn't use a standard Dial Home Device (DHD, goa'uld term unknown) to control the stargate, but instead uses a computer and a Terran-designed dialing program, which originally contained all the addresses that Daniel found on the Abydos cartouche (each of which is being corrected for galactic drift -- it takes several days to correct each address). It took fifteen years and three supercomputers to figure out a way to make the stargate work. (Children of the Gods)
  • The keyboard attached to the dialling computer has DHD symbols on it instead of letters. (multiple eps)
  • Hitting "escape" on the keyboard cancels a dialing sequence. (Bloodlines)
  • As well as dialing out, the computer controls incoming wormholes, by controlling the iris over the stargate. Anyone coming through the Earth's stargate has to send an appropriate code for the computer to recognize, or the iris will not be opened. (Children of the Gods, The Enemy Within)
    • Code upon recognizing Jack's incoming signal ("signal code response") first line: 7062957 second line: 0282002 (Fire and Water)
    • GDO code appearing on the SGC monitor: 32-333-0, identified as Jack (Fire and Water)
• Planetary designations: A six-character sequence based on a binary code the computer uses for extrapolation, usually taking the form P-number-letter number-number-number (if the sequence begins with M, it indicates a moon rather than a planet). E.g., the planet SG-1 travels to in Broca Divide is known as P3X-797. (Broca Divide)
• After Jack gets an alien database downloaded into his brain, he programs the gate computer with stargates not on the Abydos cartouche, giving the SGC a strong advantage over the Goa'uld. (Fifth Race)
  • Addresses from the cartouche appear in yellow on the dialling computer monitor; those from the Ancients' database appear in red. (Fifth Race)
  • Example of advantage: stargate address references from the Abydos cartouche including the Loc'na ko, the group of planets that includes Kheb, but without including Kheb itself. The Ancients' original map included Kheb. (Maternal Instinct)
• The original research team had to create an interface between the computer and the stargate. They did this by generating a aseries of instructions based on electrical impulses to which the gate's control crystals would respond. They found these by trial and error -- thus the fifteen years. (48 Hours)
• The dialing program ignores 220 of the 400 feedback signals the gate can emit during a dialing procedure. (48 Hours)
• A margin of error in calculating planetary shift caused travellers to experience a rough ride in the early days of the SGC program, but once they figured it out they fixed it. (Red Sky)
• Sam eventually developed a new cold dialing program that searches for new stargates by periodically redialing cartouche stargate addresses that hadn't connected the first time. The planet P2X-416 (Bedrosia & Optrica) was the first connection made by the new program. (New Ground)

• The second gate was originally buried in the Antarctic, about 50 miles away from McMurdo Station.(Solitudes)
• After it was recovered, it was supposed to have been sealed, decommissioned, and sent to Area 51. (Touchstone)
• Instead, it was moved under classified non-military authorization to an unofficial NID landing site in southern Utah, just south of the Black Mountains, about 40km west of Parowan. (Touchstone)
• It was finally returned to Area 51, sealed with a permanent iris, and put under round-the-clock guard under the command of Hammond and the SGC. (Touchstone)
• An energy spike can be created deliberately, causing the wormhole to jump to the second Earth gate, and leaving a recognizable energy signature. (Touchstone)
• The first stargate was lost after Jack, Sam, and Teal'c transported it onto Thor's ship, the Biliskner, to give themselves a way to escape; the gate went down with the ship, which crashed into the Pacific. Hammond ordered that the second gate be unsealed and set up to take its place. (Nemesis)
  • The first stargate was found by the Russians, who set up their own SG program with it, until they got in over their heads and needed SG-1 to come bail them out. (Watergate)

• Code to abort auto-destruct command: 81452667 (The Enemy Within, Prisoners )
• Remote Access Code for SG-1: 7062957 0282002 (Bane)
• O'Neill's authorization code is 81452667 (Prisoners, A Matter of Time) -- same as code to abort auto-destruct in "Enemy Within".

top | Codes

• Code Three alert: used when it's discovered that Nirrti has been roaming the base invisibly, in conjunction with a request for zats and TERs. Possibly a code indicating the need for a security sweep. (Rite of Passage)
• A Code Five Lockdown mandates that the mountain be sealed and anyone attempting to leave will be shot. (The Broca Divide)
• Wildfire Directive (authorization code red dash beta): requires level 4 quarantine, internal power and life support, and nothing in or out of the mountain. In the event of containment failure, Wildfire kicks in automatically. (Message in a Bottle)
• Code Nine seems to indicate some sort of alien invasion: used when people start vanishing all over the base in Spirits, used when O'Neill disappears via Asgard transporter in Fair Game and Nemesis.
• Foothold Situation indicates a hostile alien takeover of the SGC (Foothold).

• Cargo ship: Originally Jacob's (Summit/Last Stand). The SGC went to Vorash to commandeer the battered ship to save the Earth from an asteroid (Failsafe). They hung onto it at least long enough to use it to rescue Heimdall and Thor. (Revelations) No word on it being destroyed or returned to the Tok'ra, but no mention was made of it as a possible answer to the problems in Redemption (either to remove the stargate or to go for help).
• Death gliders: Two taken from Apophis' ship during an escape (Serpent's Lair), which were being researched at Area 51 (Touchstone). At least one was turned into a converted death glider (the X-301). Jack and Teal'c obtained two more gliders from Anubis' drowned ship in the Pacific. (Descent)
• Glider cannon: Jack, Teal'c, and Sam salvage a cannon from a glider that Jack shot down, and bring it back home with them. (The Fifth Man) Teal'c gets very fond of it as a weapon; it's what he uses to kill Tanith (48 Hours)
• Ha'tak vessel taken by Jack when Cronus was killed; before Terran scientists and engineers could get a look at it, Hammond lent it to the Tok'ra to aid in the evacuation of Vorash, and during the process the ha'tak was flung into another galaxy and eventually destroyed. But Jack had himself a ha'tak for a few days there. (Double Jeopardy, Exodus, Enemies)
• Goa'uld healing device; was Kendra's, given by Gairwyn to Sam. (Thor's Chariot, Fair Game) It's kept in a locker (likely on level 21, and probably somewhere in the infirmary itself, but no actual proof of that); keypad code is five digits, the first three of which are 9-1-8. (Meridian)
• Second Goa'uld healing device; taken from Nirrti's lab, and used in conjunction with the device that fits over the palm. Seems to be a more focused instrument. More instruments were also taken, probably medical in nature, but so far undetermined. (Rite of Passage)
• Invisibility device taken from Nirrti after she was captured on the base -- it's a bit fried from being zatted, but they have it. (Rite of Passage)
• Intars taken from the Jaffa training camp in Rules of Engagement. They look exactly like real weapons, except instead of bullets they project energy in low doses (meant to stun, not injure). Intars are easily identifiable by the glowing red square on their handles. They're now being used in SGC training exercises. (Proving Ground)
• Goa'uld ribbon device; was Kendra's, given by Gairwyn to Sam (Thor's Chariot, Fair Game)
• A ring used to "call down lightnings" by the canons of the medieval village ruled by Sokar. (Demons)
• One half-finished Goa'uld ship (unknown type), built by a bunch of cloned symbiotes as a way to escape Earth. (Nightwalkers)

• Mimic devices, from the Foothold aliens. Twelve were recovered after the explosion, including the devices used to mimic Jack, Daniel, Janet Frasier, and Major Davis. They were kept under very tight security; even the mention of the incursion had been wiped from all records. Area 51 spent some time working on developing similar items, but without much luck. (Smoke and Mirrors)
• Page-turning device (PTD) (Legacy)
  • Ma'chello's altered PTDs, which contain Goa'uld-killing bioengineered thingies. Ma'chello's inventions are activated ten at a time by the PTD. They infiltrate the host body, killing the symbiote, and die when they recognize the protein marker. In an uninfected human they cause symptoms of schizophrenia, including increased dopamine levels, migraines, paranoid delusions, and auditory and visual hallucinations.
• Quantum mirror found on P3R-233, which gives access to alternate realities. (There But for the Grace of God, Point of View)
• Tollan sub-space transmitter left behind by the Tok'ra so that the SGC can contact them (Show and Tell)
• Formula for symbiote poison, which the Tok'ra saved on a crystal and which Sam took possession of. The poison kills any symbiote exposed to it. (Summit)
• Several TERs left behind by the Tok'ra so the SGC can find/fight Reetou (Show and Tell)

• Ability to build a naquadah-enhanced nuke that packs 1,200 megatons -- the most powerful bomb ever built on Earth (equivalent to 1 billion tons of TNT) (Failsafe)
  • Particular bomb used against the asteroid in Failsafe:
    • deactivation code: 03310310
    • faulty design: wires from timer to detonator were all yellow -- there was supposed to be a red one to cut to deactivate the bomb
    • toolbox on back: S6/94882
• Technology for a naquadah reactor (Learning Curve)
• Portable naquadah reactor
  • Can be used as a power source to manually dial the stargate. (New Ground)
  • If a feedback loop is created within a naquadah reactor, it will build up energy rather than releasing it and create a powerful bomb. (Scorched Earth)
  • If it overloads and explodes, it would destroy an area several miles in circumference. (Allegiance)
  • If its output is modified to generate a high-energy EM field, in the range of 400-700 nanometers, it can be used as a sort of TER, to locate phase-shifted beings previously invisible, by exciting the phased particles enough to bring them into the visible light spectrum. (Allegiance)

• Hyperspace-window generator: Based on naquadria, and much smaller than Goa'uld versions. Capable of being fitted onto a two-man ship. (Redemption, part 1)
• Mimic devices, based on those recovered from the Foothold aliens. Area 51 spent some time working in great secrecy on developing Tauri versions, but without much luck -- the longest any of them lasted was six-plus minutes, and three or four minutes was more common. (Smoke and Mirrors)
• Missiles: Not specifically SGC-related, but the launch function is. Launched from a device either connected to the gateroom's ceiling and lowered, or brought in as a crane of some sort. The launching system holds two missiles that are launched independently. (The Sentinel)
• Repair: now have instruction sheets on how to repair Goa'uld systems (hyperdrive, life support, etc.) (Failsafe)
• UAVs: Not specifically SGC-related, but they get used a lot. They function not only as recon (One False Step, Beast of Burden), but also paint targets for missile attacks. (The Sentinel)
• Voice disguisers: Presumably engineered at Area 51, since the SGC didn't get them from any other source that we know of. Makes the user sound Goa'uld or Tok'ra, and can be turned on or off at will. (Proving Ground)
• X-301 Interceptor: Combination of death glider and jet fighter. Designed as a platform from which to launch an attack on  invading Goa'uld vessels. Equipped with stealth capability, and armed with two Aim 128A air-to-air missiles, each loaded with a  naquadah-enhanced warhead and a shield modulator, which would in theory allow the missiles to break through a Goa'uld force shield. The detonation would be enormous. Following testing, the ship was to be assigned to orbital defense under the command of the SGC. Unfortunately, the death gliders were programmed by Apophis to return to Chulak. The pilot would inevitably die en route. Jack and Teal'c nearly died in space as a result, but were rescued just in time. Unknown if the plane was rescued as well, or if it's still floating in space. Also unknown if more are being built. (Tangent)
• X-302: Unlike the X-301, the X-302 was entirely human-built, although many of its systems were reverse-engineered from Goa'uld tech. It has four different sets of engines: air-breathing jets, modified aerospikes for high altitude, a rocket booster, and a hyperspace window generator. (Redemption, part 1) Engines were designed for a craft with an inertial dampening system that effectively reduced its overall mass. (Redemption, part 2)
  • Potentially the first human-built spacecraft capable of interstellar travel. It went on its first test flight weeks too early, in an attempt to contact the Asgard to get help fending off Anubis' attack. The hyperspace generator failed to work properly, generating an unstable window. (Redemption, part 1)
  • 605-3 error: if the X-302 can't get a lock on its destination once the hyperspace window is opened, it auto-aborts. Built-in safety procedure. (Redemption, part 1)
  • Apparently remained in production after the prototype was destroyed; in the meeting with the ambassadors to disclose the SGC's program and progress, while explaining the X-302, Major Davis confirmed that "the United States Air Force is currently flying a fighter-interceptor that is capable of both aerial combat and space flight." (Disclosure)
• X-303: Successor to the X-302.
  • No idea at first what it was like, other than that it was at least on the drawing board while the X-302 was being produced. Possibly very similar to the X-302, but with a more stable hyperspace-window generator. (Redemption, part 2)
  • Codename for the project is Prometheus. The ship is huge, far larger than the two-man X-301 or X-302, and is big enough to hold multiple landing/docking bays that easily fit death gliders. It looks like a cross between a Navy destroyer and an Asgard ship. (Prometheus)
  • Pretty much has to have been in the works since before Jonas appeared with the naquadria; it's just too big and complex to have been conceived, designed, and constructed in less than a year. (This is opinion, not canonical fact.) (Prometheus)
  • It was being built in the Nevada desert, in a facility hidden several hundred feet under a simple shed (painted in a red and white checkerboard pattern, for some unfathomable reason) surrounded by a chain-link fence -- supposedly the most secure facility on the planet (until it was breached by a camera crew...). Part of the protection was its location: on grounds labelled a weapons testing area, with signs promising criminal prosecution to any unauthorized person found within the area's boundaries. (Prometheus)
  • Before it was finished, it was hijacked by a rogue NID team in deep cover as a camera crew for Julia Donovan, who were working for Colonel Simmons and the Goa'uld inside Adrian Conrad. SG-1 got it back. (Prometheus)
  • The first ship was finally officially designated Prometheus, and is the first of several X-303s planned. (Memento)
  • Physical structure:
    • Hull and walls/decks are made of trinium alloy. (Prometheus)
    • Has at least eight decks; Carter was locked in a storage room (CC4-107) on deck seven, with the sublight control relay above her on deck eight. (Prometheus)
    • Engines and structural integrity fields were modified by the Asgard to their full potential, so the X-303 could be put to use helping the Asgard. (Unnatural Selection)
    • It was designed to carry a complement of eight X-302 fighters, and is one of several planned. (Disclosure)
    • Contains a set of transport rings, activated by what appears to be a Goa'uld control panel (a gold-orange panel sitting on the standard battleship-grey walls, and with buttons the same general size as Goa'uld buttons, and that make the same sound Goa'uld buttons do when pushed). The rings function exactly as they do on Goa'uld ships, with an inset in the floor retracting so the rings can pop up, then sliding back out to make the floor solid again after the rings transport people and then return to their storage place below the floor. (Memento)
  • Hyperdrive:
  • Research and development on the hyperdrive alone ran more than $2 billion. (Disclosure)
  • If the hyperdrive generator is activated on the ground, with its energy not channeled into creating a hyperspace window, it will explode with huge force -- enough to turn Nevada into a smoking crater. (Prometheus)
  • The hyperdrive shuts down automatically if the computer detects some instability in the naquadria powering the engines. (Memento)
  • The hyperdrive is fitted with a buffer (like a surge protector), designed to modulate extreme fluctuations in the energy coming from the naquadria. Without the buffer, there's no way to control the naquadria energy, or to predict how far the ship will travel. There's also no way to be sure the naquadria reactor doesn't go critical. (Memento)
    • There are no redundancies built into the buffer system; if it blows, there's no way to repair it without returning to Earth and replacing it (or contacting Earth, and repairing it with a crew sent through the stargate). (Memento)
  • During the ship's shakedown cruise, it passed through intense gravity waves while in hyperspace, and the buffer failed. (Memento)
  • An attempt to use the hyperdrive without the buffer for a few brief moments was enough to cause the reactor to go critical; it had to be jettisoned. (Memento)
  • Shields and weapons:
    • The Asgard sent Thor to Earth (or he came on his own), after SG-1 saved them from the Replicators again, to install new Asgard-designed shieds and weapons on the X-303, as a sign of gratitude. (Disclosure)
    • The ship has at least four missile bays. (Memento)
  • Flight capabilities:
    • Capable of achieving orbit in under 30 seconds, but inertial dampeners and artificial gravity would keep the g-forces in check. Using sublight engines, the ship can reach 110,000 miles per second. (Prometheus)
    • Travelling with sublight engines, not using the hyperdrive, the Prometheus could travel 0.38 lightyears in about four months (so, obviously, about 0.1 lightyear in a month) (Memento)
  • Crew:
    • SGC personnel, complete with SGC and team patches (no ID on the team designation yet), and with rank insignia, unlike the usual SG field units. They also wear US Space Command patches and patches showing their primary badge (pilot, etc.) and name. (Memento)
    • Exact crew size is unknown.
      • At least three people were stationed on the bridge:
        • Colonel Ronson, in command (Memento)
        • Major Gant -- hyperspace officer, maybe? also responds to a call for weapons to be armed (Memento)
        • unnamed crewmember (Peter something, wearing a senior-pilot badge): Ronson calls him the weapons officer, and the credits list him as navigator (Memento)
        • Two (unnamed) others seen working in the background as well. (Memento)
      • Crewmembers were also walking around the ship.
    • Commanded by Colonel William Ronson. (Memento)
  • Shakedown cruise:
    • SG-1 was aboard in case of emergencies, at the request of generals Greer and Hammond. (Memento)
    • Commanded by Colonel William Ronson. (Memento)
    • The hyperdrive buffer failed while the Prometheus was passing through intense gravity waves while in hyperspace; the computer shut down the hyperdrive and dropped the ship back into normal space. (Memento)
    • An attempt to use the hyperdrive very briefly without the buffer, to reach a nearby world that was believed to have a (possibly buried) stargate resulted in the naquadria reactor going critical, and being jettisoned. (Memento)
    • The EM shockwave of the exploded reactor penetrated the ship's shields, knocking out the primary computer systems, leaving only gravity and life support on most decks. (Memento)
    • The shockwave headed the other direction convinced the people on the planet that they'd been attacked, and they returned the gesture with missiles. (Memento)
    • The Prometheus was forced to land on the moderately hostile world in hopes of finding the stargate; after a brief to-do, they did. (Memento)
