Sublight engine

Sublight engines are engines found on ships which propel them through normal space without going beyond the speed of light.

Ancient
The Ancients equipped their vessels with extremely fast sublight engines. Puddle jumpers are capable of crossing the Lantean system in under 15 hours, faster than anything Earth has made. One ship, the Tria, had her sublight drives modified to propel the vessel at 0.999 times the speed of light, the fastest sublight speed ever encountered by the Tau'ri, although they had access to a ZPM giving them a significant power boost. Even City-ships are remarkably maneuverable considering their size.

Asgard
The Asgard have fast and very maneuverable sublight engines. An O'Neill-class ship has been seen making sharp turns at high speeds and engaging in dog fighting-style tactics, despite its massive size.

Goa'uld
Goa'uld sublight drives are equipped aboard all ha'taks vessels. Despite their large size, the sublight drives of ha'tak's are quite fast and maneuverable. Sublight drives on death gliders are also quite fast and maneuverable. These drives are used to decelerate after exiting hyperspace.

Ori
Ori Battleships and fighters are quite fast. The Ori fighters appear to fly at speeds previously unseen, possibly faster than death gliders.

Tau'ri
The Tau'ri possess relatively powerful sublight engines, which are installed on Prometheus and Daedalus-class ships. The sublight engines on the Prometheus' were capable of accelerating to 110,000 miles per second, over half the speed of light. It is unknown the speed at which Daedalus-class ships can travel, but because of the Tau'ri's current level of technology, it is possibly faster.

Traveler
The Traveler possess highly maneuverable and powerful sub-light engines.

Wraith
The Wraith have less efficient sublight drives on their larger capital ships, but the drives on Darts are quite fast. They also give off a distinctive (and disturbing) whining noise.
