The L-s9.3 laser cannon was a type of laser cannon that was manufactured by Sienar Fleet Systems. Created for the prototype TIE Advanced x1, it was much more powerful than the standard L-s1 model fitted on standard TIE/ln space superiority starfighters. It was also used aboard TIE/IN interceptors, the TIE/rp Reaper attack lander and the TIE/sk x1 experimental air superiority fighter.
