- "You always hear them first. Twin ion engines make TIE fighters howl as they fly by on patrols."
- ―Ezra Bridger, on TIE fighters

The twin ion engine of a TIE/ln space superiority starfighter
The twin ion engine was a type of ion engine which propelled starships in space. The sublight drive was widely incorporated into various models of starfighters.[2] The engine was used in Sienar Fleet Systems' TIE fighter series and made the distinct high-pitched shrieking sound they were known for.[3]
The TIE/sk x1 experimental air superiority fighter, also known as the TIE Striker, was a model of the TIE line in service to the Galactic Empire. This atmospheric fighter's twin ion engine[4] emmitted a blue light.[5]
