Omar

Omar is a lanet located in the system of the same name. It was where three Sienar Fleet Systems starfighter production facilities were. They produced the TIE Defender. The facilities were destroyed by Admiral Zaarin after the Battle of Hoth in and open act of treason to the Empire in an attempt to destroy the Empire's advanced war materials.

It was Grand Admiral Thrawn who hunted down and for the first time unleashed the use of Sienar's TIE Defenders to destroy Admiral Zaarin.

Over the years Sienar has rebuilt the facilities on Omar but has only used these facilities for limited use. The most recent use being the development of the Alph-class starfighter.
