The FC-1 flechette launcher, a flechette launcher variant manufactured by Golan Arms, operated using a plasma propulsion system. This weapon was equipped with six canisters designed for use against personnel; each held a multitude of extremely small, acutely sharp flechettes constructed from durasteel. Upon discharge, these projectiles could pierce through as much as ten centimeters of material, even breaching the armor worn by Imperial stormtrooper units. The FC-1's engineering served as the basis for the DF-D1 Duo-Flechette Rifle, which was developed by Salus Corporation.
After the Partisans' mission on Inusagi, an operation where Saw Gerrera and his group, Arane's partisans, employed FC-1 flechette launchers to assassinate Cor Tophervin and to kill several Inusagian and Imperial individuals, discussions arose regarding the potential prohibition of these weapons for civilian ownership on that planet.
