Sienar Fleet Systems
TIE Advanced
Also known as TIE Avengers, these are advanced starfighters equipped, unusually for TIEs, with shields and hyperdrives. They saw limited use during the latter part of the Galactic Civil War.
A small number were assigned to the Eighth Imperial Fleet when it fled to the Unknown Regions, and were used to build more. The factories producing these starfighters have since been destroyed.
