The EF76 Nebulon - B escort frigate was an escort frigate manufactured with a highly versatile design platform that allowed it to function in several different capacities as part of a fleet . The vessels featured a propulsion module that housed 7 aft - mounted ion engine s connected to the forward blade - like body by a thin , cylindrical hull section . The propulsion module also contained the ship ' s deflector shield generator situated at the top of the craft .

The primary medical bay had the capacity to house 700 patients . Role . Boasting a highly versatile design platform , the Nebulon - B frigate served in a range of capacities , although was typically utilized as an escort frigate . The Rebel Alliance deployed these frigates to protect transport convoys from Imperial attacks or pirate raids , although some were modified for long - range scouting or search - and - rescue operations . However , the Nebulon - B became most famous for its use as Rebel medical frigates , and many were equipped with full - service hospital facilities . History . The EF76 Nebulon - B escort frigate was created by Kuat Drive Yards , for the Imperial Navy , although they were more commonly used by rebel cells of the formative Alliance to Restore the Republic against the Galactic Empire . Nebulon - B frigates were often used as convoy escorts . Berch Teller and his cell utilized a Nebulon - B to attack a convoy containing the hyperdrive of the Death Star around five years after the end of the Clone Wars . Several of the frigates were part of the fleet which assembled over Dantooine in response to Mon Mothma ' s declaration of rebellion in 2 BBY , and several were fielded by General Jan Dodonna ' s Massassi Group during the Battle of Atollon , although the fleet suffered heavy losses with several of the frigates lost to Grand Admiral Thrawn ' s forces . Admiral Raddus had at least three Nebulon - B escort frigates in his fleet when Rogue One went to Scarif to steal the Death Star plans , and participated in the subsequent battle . At its conclusion , one frigate successfully managed to escape into hyperspace , but another was destroyed under heavy fire from Darth Vader ' s Star Destroyer , " Devastator " . Following the Battle of Yavin and the evacuation of Yavin 4 , the Rebel leadership maintained a constantly - moving fleet , keeping on the run while seeking a new base of operations , and utilized a Nebulon - B as their temporary headquarters ship during this period . From here , Mothma , Dodonna , Admiral Gial Ackbar , and others planned operations against the Empire after the attack on Cymoon 1 . Han Solo recuperated aboard while repairing the " Millennium Falcon " with Chewbacca , and Luke Skywalker briefly trained in one of the frigate ' s chambers before departing for Tatooine . Solo and Leia Organa later departed on a scouting mission to secure a new base , leaving the Rebel leaders to discuss Skywalker ' s troubling activities in the ship ' s command center . Although Mothma was unable to commit any forces to assist Skywalker on Nar Shaddaa , Chewbacca and C - 3PO volunteered to help their friend . Sometime later , the Rebel leadership met with Organa and Skywalker in the command center , and tasked them with a mission to Tureen VII , leading the pair to embark on a mission to steal a Star Destroyer . As of the time of the mission to rescue C - 3PO , the Nebulon - B was part of a much larger contingent of the Rebel fleet . As of 3 ABY , the Nebulon - B frigate " Redemption " served as a medical ship for the Rebel Alliance . Following the Battle of Hoth , Skywalker was treated aboard the frigate for injuries received during his confrontation with Darth Vader on Cloud City . At least two Nebulon - B frigates were part of the Rebel fleet at the Battle of Endor , and at least one survived to join Rebel Fleet Command at , twenty days after Endor , and later at . Numerous Nebulon - B frigates went on to serve in the New Republic . At the Battle of Jakku , Commodore Kyrsta Agate witnessed a Nebulon - B break in half under heavy fire but continuing to unleash its full complement of weapons at a Star Destroyer nonetheless . Another Nebulon - B later crashed into the flagship of Admiral Garrick Versio , the " Eviscerator " , further compromising the already crumbling ship ' s integrity . At least one Nebulon - B , going by the name of " Opportunity " , served under the banner of Jinata Security , a law enforcement agency based on the planet Vardos in the Jinata system . Captain ed by Leema Kai and painted in the colors of Jinata Security , the ship assisted the First Order in implementing Project Resurrection across the Jinata system by kidnapping children and conscripting them to become First Order stormtroopers . Whilst preparing to resume this operation on Athulla , the " Opportunity , " and its modified GR75 escorts were accosted by Iden Versio and her daughter Zay who had been led there after finding that Del Meeko ' s ship " Corvus " had been investigating the kidnappings on behalf of the Resistance . The frigate deployed fighters and fled deeper into Athulla ' s asteroid field in an attempt to lose them , but the two women took out its escorts and crippled the ship by destroying the engines . Whilst Iden battled with Kai , Zay contacted the " Opportunity " and tricked them into surrendering by threatening to unleash a barrage of non - existent concussion missile s on it . The ship ' s crew , believing them , not only surrendered the " Opportunity " but gave up all the information they had on Project Resurrection . Sometime after the Battle of Jakku , the Nebulon - B would inspire its successor , the Nebulon - C escort frigate , which would be commissioned for the New Republic fleet . At least one , the Anodyne , would be modified into a medical frigate and serve in the fleet of the Resistance .
