Iron Ring was a Lucrehulk-class battleship that fought under the Separatists during the Clone Wars and briefly after as one of many Separatist holdouts before being destroyed by Imperial warships on the fringes of the Karthakk sector during a failed assault on an Imperial resupply station in 15 BBY. Commander Herson Tiggit, a former arms smuggler from Corellia who captained Iron Ring, survived the carnage and went into hiding for years, only to later reemerge as a captain in the Rebel Navy. Another survivor (who worked aboard Iron Ring as a communications officer) later served the Rebels as the commander of a remote listening post, which was named Iron Ring Outpost in honor of the fallen battleship.
It was mostly crewed by OOM-series droids and was commanded by Humans from the Core Worlds, most of whom started their careers as privateers secretly contracted by the early Confederacy to disrupt trade routes in Republic space during the Separatist Crisis. It also maintained a swarm of vulture droid starfighters (Trade Federation patrol variant) and a cohort of BX-series droid commandos that served as strike teams in ground operations or ship boardings; these droid commandos were deployed into battle via automated boarding crafts.
