Viscount - class Star Defender The " Viscount " - class Star Defender was a very large warship series developed by the Mon Calamari for use by the New Republic Defense Fleet . Characteristics . Dimensions . The " Viscount " - class Star Defender was envisioned as the New Republic equivalent of an " Executor " - class Star Dreadnought . The first prototype was a 3 km long battlecruiser , measuring almost twice as much as the " Mediator " - class battle cruiser . The full production model was a 17 km long dreadnought . Although slightly shorter in length than the " Executor " - class , the superior construction skills of the Mon Calamari enabled the vessel to carry more starfighters , as well as having a substantially smaller crew . Its shape was also more compact than the " Executor " - class and it had heavier and more extensive armor . Dozens of docking clamps allowed the vessel to directly dock with many other capital ships at the same time . Offensive and defensive systems . The " Viscount " - class was equipped with over five thousand weapons systems , including heavy turbolaser batteries and assault concussion missile launchers . The " Viscount " ' s shields had backups , like previous Calamari designs , and were thus highly regenerative . The computers , electronic equipment , and sensor systems were above and beyond those of an Imperial Star Dreadnought , and it carried a HoloNet transceiver as well . Its heavy armament was on par with the Empire ' s Executor Class Star Destroyer . Complement . Ships of the class could carry hundreds of starfighters , as well as dozens of small support vessels , including frigate - sized ships . The class was also fitted with enough life pods to carry the crews of the ship itself , and also those of whatever smaller support vessels were carried at the time . This totaled a passenger - capacity of 500 , 000 individuals . The ship was also equipped with enough repair droids to cover the entire vessel during emergency repairs . Other systems . To support wounded in combat , the " Viscount " - class had hundreds of self - replenishing bacta tanks in its medical wings . It also had fighter repair bays , for the repair and maintenance of the ship ' s starfighters . History . Development . The design series began its history around the time right after the Battle of Endor . Despite having beaten the " Executor " in combat at the climactic battle , Admiral Gial Ackbar considered the various Super Star Destroyers , still in Imperial hands , as the main threat to the burgeoning New Republic Navy . With this in mind , he proposed the creation of Super Star Destroyer - scale warships to counter the Imperial vessels . It took many years of development , combined with the threat of the rogue " Executor " - class Star Dreadnought " Intimidator " during the Black Fleet Crisis , to move the development program forward and actually produce the larger dreadnoughts . Despite having utilized Mon Calamari battleships and " Bulwark " - class battle cruisers in previous decades , the New Republic had never constructed anything on this scale before . Regardless , the Mon Calamari finally began development of the " Viscount " - class after the Black Fleet Crisis . Construction on the class dragged on , as the threat posed by the Imperial Remnant diminished and the New Republic captured several Star Dreadnoughts during the war . Active service . The first ship of the class , the smaller prototype battlecruiser " Viscount " , was eventually completed in time to engage rogue Imperial warlords , pirates , and hideouts . It was noted as being commissioned in 25 ABY , shortly before the Yuuzhan Vong War began . The " Viscount " ' s brief career of Civil War - related battles constituted the only events in which the class was used for its original purpose , battling Imperial targets . At least one confrontation involved an " Executor " - class Star Dreadnought on the opposing side . The Calamari " Viscount " battlecruiser and dreadnoughts , along with Corellian - made " Viscount " s and the Corellian " Strident " - class , marked the only known Star Defender ship types , all participating in the Yuuzhan Vong War . When the New Republic government transitioned into the Galactic Federation of Free Alliances , the " Viscount " - class continued to play a prominent role in the fleet . The ships were even regarded as the backbone of the Galactic Alliance Defense Force . In 27 ABY , the dreadnought " Krakana " was deployed to Kuat to act as an orbital battery , but was assaulted by the Vong en route and destroyed . Its sister ship , the " Bounty " , while still unfinished , held off the Yuuzhan Vong from attacking Mon Calamari directly for years . When the war finally came to Mon Calamari , the power of the " Viscount " - class Star Defender was made evident during an epic naval battle . The " Viscount " herself formed part of a trio of heavy warships that was deployed in formation by the Galactic Alliance Defense Fleet . The other two were the " Executor " - class " Guardian " and the Mon Calamari battle cruiser " Harbinger " . These three large warships used their heavy , long - range weapons to assault the center of the Yuuzhan Vong armada . The heavy guns of the " Viscount " were instrumental in destroying numerous enemy warships . Retirement . By the Sith – Imperial War , the " Viscount " - class and other heavy warship - designs in the battlecruiser and dreadnought range , had been phased out of service . Fleet doctrine moved towards smaller , compact weapons - platforms and new Calamari designs reflecting this change , like the MC140 " Scythe " - class main battle cruiser , dominated Alliance fleets .
