The Twin-Port Ion Stream Exhaust Vent, alternatively called twin-port deflectors, functioned as a control and channeling mechanism for the exhaust emanating from the TIE/IN interceptor's Microparticle Ion Accelerator, a starfighter component, thereby generating thrust. Its construction involved a classified military alloy. These deflectors featured a high degree of precision and individual control, facilitating equilibrium during sharp turns and extended aerial maneuvers.
