The L-s9.3 laser cannon represents a specific variety of laser cannon originating from the production lines of Sienar Fleet Systems. Initially designed for incorporation into the experimental TIE Advanced x1 prototype, its power output significantly exceeded that of the more common L-s1 model typically found on standard TIE/ln space superiority starfighters. Its deployment extended to platforms such as TIE/IN interceptors, the TIE/rp Reaper attack lander, and the TIE/sk x1 experimental air superiority fighter as well.
