Behind the scenesEdit

In Star Wars Legends, Gemon-4 ion engines were first identified in The Galactic Empire—Ships of the Fleet pop-up book, however, with their canon identification in Ultimate Star Wars, they appear to be the Imperial-I's primary and only ion drive, supplanting the Destroyer-I ion engine.
