"Star Wars" literature states that Grand Moff Tarkin commissioned Sienar Fleet Systems to design and manufacture the Twin Ion Engine line edition (TIE/ln) space superiority starfighter and most TIE variants. Tarkin specified that the TIE had to be fast, maneuverable, energy-efficient, and inexpensive; simply put they are meant to be easily mass-produced and engage in swarm tactics, with the expectation of being expendable assets that would be lost in combat. To meet these requirements, Sienar incorporated aspects of the V-wing and Jedi interceptor into the new starfighter.
