The Millennium Falcon utilizes sublight engines for propulsion.
A sublight engine, alternatively referred to as a sublight drive, constituted a crucial component in starships, enabling them to traverse realspace at velocities below that of light. The ion engine represented the most prevalent type of sublight drive. Notably, the TIE fighter employed a pair of these engines to attain its remarkable speeds.
Typical speeds achieved with sublight drives were quite significant, reaching a considerable fraction of light speed. A freighter-class ship, when propelled by a sublight drive, could exit a planet's atmosphere and overcome its gravity well within mere minutes.
The most frequently used sublight drive was manufactured by Hoersch-Kessel Drive, Inc., and it was incorporated into various vessels, spanning from the T-16 skyhopper to the Imperial-class Star Destroyer. Durafly was also a producer of sublight drives.
