This was Darth Vaders Proto-type of the rouge shadow in its first production, he had the sienar company produce this as a possible later fighter. Based upon future tie designs and possible intercepter designs this was Vaders flagship and his personal ship. He used this extensively as he played with and modified the design. this was a highly manuverable ship with the agility of a tie and speed of an v-wing. in the end Vader moved for a bigger ship and the proto-type was scraped.
