Sienar Advanced Systems

Sienar Advanced Systems was a company that manufactured the SIE-TIE twin ion engine system prior to the Clone Wars. It was run by Raith Sienar, and was a subsidary of Santhe/Sienar Technologies.

It is possible that Sienar Advanced Systems was linked to the Sienar Advanced Projects Laboratory that was in existence in some form as of 29 BBY&mdash;and indeed, these companies may have been one and the same.
