The T-s8 targeting computer, created by Sienar Fleet Systems, was intended for installation in their TIE/ln space superiority starfighters. This system's purpose was to calculate a target's trajectory and velocity, enabling pilots to lead their shots effectively. This functionality was integrated with weapon systems that powered up extremely quickly, guaranteeing target impact.
Subsequently, the T-s9a targeting computer offered superior performance, leading to the upgrade of older T-s8 units with the newer technology.
