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 another dual-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.
Behind the scenes
The TIE Sentinels are given a mention in the Star Wars: Galaxies expansion, An Empire Divided in a painting known as Emperor's Eyes, where looking at the painting will show the subtitle that names the craft. Despite this, however, it is not a usable craft, nor does the starship appear anywhere else in the game.
