"Ladies and Gentlemen, Welcome to Atlantis."

— Major John Sheppard

Atlantis, also known as the City of the Ancients, City of the Ancestors or Atlantus in Ancient, is the best known city ship of the Ancients, the capital of the Ancient civilization in both the Milky Way and Pegasus galaxies and one of the few surviving Ancient ships, technology and structures in the known universe.

Energy

The Stardrive active

The city was designed to be powered by three Zero Point Modules connected to the cities main power conduits through a hub in the cities central tower. The city can function with one or two ZPM's however its functions may be limited to certain systems. The city also has a number of lightning rods, solar power generators and solar panels to supplement the cities power supply. An underwater mobile drilling platform connected to the city with an umbilical cord can also supply the city with power. The Atlantis expedition also supplemented the power supply with naquadah generators. (ATL: "Before I Sleep", "The Storm", "The Eye", "The Last Man", "Submersion", "Rising")

Stardrive

Main article: Stardrive

Atlantis, and presumably other city ships, have a very powerful Stardrive to provide the city with its primary faster-than-light travel technology. The stardrive is one of the fastest hyperdrives built, by any race, capable of traversing the three million light year distance between the Pegasus and Milky Way galaxies in less time than an Asgard hyperdrive is capable of doing. The stardrive is capable of being powered by only one Zero Point Module, however the stardrive also requires the shield to be active during transit due to the cities frailty. (ATL: "Enemy at the Gate", "First Strike", "Adrift", "Lifeline")

Atlantis' shield

Wormhole drive

Main article: Wormhole drive

Atlantis also has the only wormhole drive in known existence, capable of faster-than-light travel sending the city hundreds of thousands of light years in only a few seconds. The technology was adapted from other Ancient technology but is dangerously unstable due to its power requirements, which if calculated wrong could vaporise the city. (ATL: "Enemy at the Gate")

Drones being deployed

Sublight engines

Main article: Sublight engine

The city has powerful sublight engines for slower-than-light travel, the engines are also responsible for the cities entry and egress into atmosphere needed for take-off and landing. The engines are capable of traveling a fast speeds and can possibly be adjusted to reach near light speed velocities. (ATL: "First Strike", "Adrift", "Lifeline", "The Return, Part 1")

Shields

Main article: Shield

Atlantis has a massive, powerful dome shield that encompasses the city, protecting the city from a range of attacks. The shield is powerful enough that when powered it can absorb attacks without causing any secondary effects such as tremors elsewhere in the city. The shield can be collapse down to a thin shell covering the buildings to conserve power or shrunk to protecting a small area and can be expanded to encompass a huge area. The shield can also be converted into a cloak. (ATL: "Rising", "The Siege, Part 3", "Adrift", "Echoes")

Drone weapons

Main article: Drone weapon

The cities primary offensive, and somewhat defensive, technology is the drone weaponry, the city can house hundreds of thousands of drones which are launched from three deployment platforms controlled by the control chair in the city. Most of the cities drones were depleted during the First Siege of Atlantis defending it against the Wraith but they were further supplemented from another City-ship. (ATL: "The Siege, Part 2", "Enemy at the Gate")

Stargate

Main article: Stargate

Atlantis' Stargate features a shield which encompasses it to prevent unwanted or unauthorised travelers. The Stargate is the only one in the galaxy able to dial 8-chevron addresses due to a specialized control crystal installed in the cities DHD. (ATL: "Rising", "Home")

Personnel

As Atlantis is a city it is capable of housing hundreds, if not thousands of occupants. Originally the city was home to the Lanteans, but it was abandoned 10,000 years ago and was not until 2004 that the Atlantis expedition arrived from Earth and occupied the city. The expedition also temporarily took in some refugees from other worlds such as Athos, Orin's planet and Tarania. (ATL: "Rising", "Suspicion", "Letters from Pegasus", "Inferno", "Vengeance")

History

Earth

Atlantis was situated on Earth on Antarctica connected to the Terra Atlantus outpost. During this time the Plague ravaged the Ancient civilization, forcing the Ancients to reseed the Milky Way with life and then leave for the Pegasus galaxy. A final Puddle Jumper returned to the city, another Ancient returned to the city from the outpost, Ayiana stayed behind for unknown reasons, the city took flight and left for a new home. (ATL: "Rising")

Pegasus

The War

Atlantis expedition

Back to Earth

Todd contacted Atlantis and informed them that one of his underlings had mutinied and taken control over a ZPM-powered Hive ship and taken it to Earth. Todd told the expedition where they could find two more Zero Point Modules which allowed them to fully power the Stardrive of the city and take it to Earth to fight the hive. During the journey the cities hyperdrive failed and they were forced to use the cities Wormhole drive to reach Earth which severely depleted their power, the fight with the hive further drained power and they were forced to land the city on Earth near San Francisco, luckily they managed to cloak the city before it came to close to populated areas. (ATL: "Enemy at the Gate")

Eventually Atlantis was removed from San Francisco bay and relocated to the moon. A safeguard to ensure that the city never left Pegasus was activated and started a self destruct sequence, which forced the Atlantis expedition to return to the Pegasus galaxy. To get back they required two jumps using the wormhole drive however it burns out after one jump and Atlantis is stranded somewhere in the Pegasus galaxy. (Stargate: Extinction)

Alternate Timelines

In an alternate timeline an expedition gated into the city, however the failsafe device that allowed the city to float to the surface was never installed so the shields failed and the city flooded, killing most of the expedition except for Elizabeth Weir, John Sheppard and Radek Zelenka who used a time machine and accidently traveled back 10,000 years. (ATL: "Before I Sleep")
In an alternate timeline, John Sheppard returned to the city 48,000 years into the future, where the city was still relatively intact however the oceans of M35-117 had turned into a desert. (ATL: "The Last Man")
