TIE Sentinels were a variant in the TIE series of starfighters utilized by the Galactic Empire. They possessed irregular folded wings and at least two turrets: One dual-turret cannon on the back of the vessel and one single-turret gun at the chin of the fighter. It possessed traits similar to that of the TIE Advanced x1 and the TIE Aggressor. It was at least planned to be developed by the Empire by the aftermath of the Battle of Yavin during the Galactic Civil War.
