Imperial-class Star Destroyer/Legends

The Imperial-class Star Destroyer was a type of Star Destroyer widely used by the Galactic Empire and the Imperial Remnant. There were two sub-classes of the line: the Imperial I-class Star Destroyer (also known as Imperator-class), and the Imperial II-class Star Destroyer.

Behind the scenes
In Star Wars Insider 125, they used a fanon artwork of an Imperial-class Star Destroyer created by Ansel Hsiao, which was labelled on his site as the Imperator-class ("Imperator" is derived from the title for the Roman Empire's head of state, which is also where the French word "Emperor" is derived from).
