The Goa’uld did not invent their technology, but rather stole it from various other cultures, most of which seems to be Ancient in origin, such as the Stargate and the Transportation rings. Goa’uld technology is based primarily around the use of naquadah, a substance that the Goa’uld secrete into the bloodstream of their hosts. Naquadah is also used as a sort of interface initializer to interact with their most valuable technology, such as the hand device and healing device, similar to the Ancient Technology Activation Gene. Most Goa’uld technology is weapon based in nature, reflecting the Goa’uld’s aggressive society.
The Al’kesh is a powerful Goa’uld medium-range bomber and troop carrier used to attack fortified positions on planetary surfaces, serving a support role during invasions by System Lords. It is larger than the Tel’tak scout ship and Death Glider, yet much smaller than the Ha’tak mothership. Following the defeat of the Goa’uld, the Al’kesh has also been used by cultures that were formerly under Goa’uld domination, such as the Free Jaffa and the Lucian Alliance.
A Death Glider is a two-seat fighter craft designed for combat in both space and atmosphere. They are the most prolific ship in the Goa’uld fleet.
The Death Glider is a crescent-shaped vessel with wings stylized to look like that of a bird. The wings curve downward, making their tips the lowest point of the vessel. When stored on a Ha’tak, the wings fold in to save space. The cockpit has room for two people; the front seat is the pilot’s chair while the rear position controls the weapons. A single pilot can do both, however. Gliders are piloted by means of a large red sphere. Direct thoughts and spoken words seem to control the craft as long as the pilot touches this device.
Gliders are capable of both atmospheric and spaceflight. They do not use direct thrust, but rather an inertial propulsion system which negates the effect of inertia on the craft. This also allows them to hover. Like most space craft, Death Gliders also possess inertial dampeners which protect the pilot from deadly G-forces. However, similar to the F-302 fighter-interceptor, they do not appear to function at 100% while traveling at high speeds. Though not designed for it, Death Gliders can be flown underwater. Due to their design, Gliders need a flat surface to land on, or a nearby mothership to dock with.
The armament of a Death Glider consists of two Staff cannons mounted to either side of the cockpit on the underbelly of the craft. These are identical in function to a regular Staff weapon, but much more powerful. They can only fire in a straight line, have poor accuracy, and low rate of fire. Because of this, Death Gliders are ill-suited for anything other than strafing runs on nonmoving targets. When faced with comparatively fast moving targets like Tau’ri jets, they rely on numeric superiority and mass volleys in the general direction of the targets.
The Ha’tak is a Goa’uld spaceship and the mainstay of their fleet. It serves a dual role as a mothership and a heavy attack vessel. The Ha’tak is one of the most powerful ships in the Goa’uld fleet, only second to the larger and quite rare flagships employed by System Lords. However, compared to other capital vessels such as those of the Asgard, Ancients, Ori, and the Asgard-upgraded Tau’ri fleet, they are clearly inferior. As with most Goa’uld technology, Ha’taks are also used by the Free Jaffa Nation and the Lucian Alliance. The Tok’ra rarely make use of them, as such a conspicuous vessel is not in keeping with their methods.
Goa’uld Healing Device
The healing device of the Goa’uld is a device consisting of a large red crystal emitter which can be slid on one’s hand. Like other Goa’uld hand devices, the healing device can only be used by people who have Naquadah in their blood such as Goa’uld, Tok’ra, and former hosts. It operation appears to be similar to the Goa’uld ribbon device, as it requires the persons strong desire or emotion to activate. It is also possible to make the device light up but not work, as Nirti did when she bluffed trying to heal Cronus with the device. The device is capable of healing Staff weapon wounds, several diseases and even near fatal injuries. It is however not as powerful as a Sarcophagus and can’t revive the dead.
The Kara kesh, also called a hand device or a ribbon device, is a multifunctional Goa’uld apparatus, and an example of their use of technology in deceiving others. It is, with the possible exception of the Staff Weapon, the single most distinctive piece of Goa’uld weaponry.
The hand device takes the form of a gold or silver colored metal ribbon, which wraps around the fingers, hand and forearm of the user; a red gem is nestled in the palm. The hand device is typically worn on the left arm, with a red gem in the center of the palm. Silver versions tend to be used by Underlords, suggesting the color denotes the status of the user. It is controlled by a neural interface, and is powered by Naquadah in the user’s blood, functionally rendering it impossible to use except by those who are or have been host to a Goa’uld symbiote. As a result of this functionality, the kara kesh must be worn next to the skin, although many users wear long sleeves, leaving only the finger coverings and the gem visible (hence the term “hand device”, even though it covers the whole forearm).
he Kara kesh has numerous functions with a variety of controls on its surface that can be used by its user. It can fire waves of kinetic energy from the palm, repelling or even killing adversaries. It has a shield to block attacks, and can absorb Zat’nik’tel blasts without harming the user. It can also emit a fiery beam of energy to torture or kill a victim. This same energy beam can allow the host to form a neural link with the victim in order to share information.
Ma’tok Staff Weapon
The Ma’Tok staff, known more commonly as simply a Staff weapon, is the primary weapon of Jaffa warriors.
The Ma’Tok staff fires a powerful plasma blast which can kill most humans with a single shot if it strikes near the center mass of the body (or other vital areas). Glancing blows will cause severe pain, but the victim may survive if the wound is treated. The high heat of the plasma blast will cauterize the wound instantly. At close range, the blast can go completely through a victim, and even blow off limbs. In addition to being lethal to humans, the blast can cause significant damage to solid objects. Staff blasts have been shown to be capable of leaving holes in a wall the size of a man’s head, blow apart trees, and even damage blast doors.
A Sarcophagus is a device the Goa’uld use to rapidly heal injuries and extend their lifespans. The device can also bring the recently deceased back to life. Despite the fact that the Goa’uld are scavengers and thieves of technology, there are a few of them who have come up with quite impressive adoptions of technology they have stolen and/or studied. Based on the Ancient healing device, but heavily modified so a human can use it, the Sarcophagus is one of the more impressive Goa’uld inventions.
Tel’taks are small transport ships used by the Goa’uld, the Jaffa, the Tok’ra, and the Lucian Alliance. The Tau’ri have also briefly made use of stolen Tel’taks, prior to acquiring their own hyperspace-capable vessels.
Transportation rings, also called ring transporters, transport rings or simply rings, are a form of transport used by a number of species, but they were originally designed and built by the Ancients before their invention of beam transporters.
Transportation rings are similar in function to Stargates, but only transport matter across planetary distances, either on the planet itself or to ships in orbit. When activated, a number of rings rise from the floor or drop from the ceiling, surrounding the object and converting it to energy. The matter stream is then transmitted to a similar set of rings (or the rings themselves simply move where desired) which reassemble the object. In order to prevent damage to people or objects during reassembly, the matter at the destination is swapped with the matter at the departure point.
The Zat’nik’tel, nicknamed Zat or Zat gun by Colonel Jack O’Neill, is a handheld weapon used by the Goa’uld and their Jaffa. It is in the shape of a serpent and was first encountered by SG-1 on Apophis’s Ha’tak. Its energy output, in the form of blue electrical energy, is less powerful than that of a Staff weapon. It’s an extremely efficient weapon and is used extensively by the Goa’uld, Tok’ra, Jaffa and Tau’ri.
Zat’nik’tels are fired by squeezing the bottom curve where the gun is held. The Zat is unique in the way it works. One shot is shown to incapacitate a victim and causes immense pain, while a second shot kills them. The shots do not have to be right after the other, as some have been killed several minutes after the first Zat blast; however, an extended period of time between shots will cause the effect to wear off and two new shots will be necessary to kill (as evidenced by Colonel Jack O’Neill’s being shot a variety of times throughout SG-1’s various exploits). A third shot will disintegrate the victim and their clothing, and will also disintegrate small inanimate objects with low densities, leaving no visible trace of their existence.
