Technology in Stargate - Asuran Technology

Asuran Technology

The Asurans (more commonly referred to as the Replicators) are sentient nanite constructs created by the Ancients to fight the Wraith. The Asurans possess the early technology of the Ancients at the time of their war with the Wraith. The Asurans use starships of Atlantean design, such as city ships and Aurora-class battleships. In "Lifeline" and "This Mortal Coil", a second type of Asuran warship is shown, smaller in size than the Aurora-class. Prominent Asuran technologies include:

• Core drive A component of an Asuran battleship's navigation system. An Asuran copy of Keller gives one to a clone of Elizabeth Weir, who in turn gives it to the Atlantis Expedition. McKay uses it to track all the Aurora-class battleships in the Pegasus galaxy.
• Probe Hyperspace-capable device used by Oberoth's forces to track down the remnants of Niam's rebel group. It is shot down over their duplicate Atlantis, though not before transmitting data back to Asuras.
• Satellite weapon Weapon sent to attack Atlantis in response to Earth's preemptive strike on Asuras, consisting of a stripped-down ship with a Stargate, hyperdrive, shield, and sensors. Once the Stargate activates, the Asurans transmit a powerful energy beam through. The beam doubles as an unlimited power source for the shield, effectively making the satellite indestructible. The wormhole can be maintained indefinitely by means of multiple ZPMs on the other side, which also prevents the target's Stargate from dialing out. Atlantis only survives the satellite weapon by moving out of range, leaving its planet for another.
