Supremacy The Supremacy , disparagingly nicknamed " Snoke ' s Boudoir , " was a " Mega " - class Star Dreadnought that served as the flagship of Supreme Leader Snoke and the mobile headquarters of the First Order . It was heavily damaged while attempting to destroy the remnants of the Resistance fleet near the planet Crait . Characteristics . Dimensions . The " Supremacy " was 60 kilometer s in wingspan and was the sole " Mega " - class Star Dreadnought in the First Order ' s service . Its construction had been on an unprecedented scale . Being the First Order ' s headquarters , the starship acted as both a command center and a battleship . Its size was gargantuan , easily outclassing all known ship sizes in galactic history , including the Star Dreadnoughts of the Galactic Empire , the trophy battlecruisers used by wealthy citizens of the waning days of the Old Republic , and even the various reconstructed versions of the flagship used by Xim the Despot . Engines . The ship had approximately 32 sublight engines , which were improved upon from the sublight engine system aboard the two Death Stars . It also possessed at least six fusion reactor complexes at the Starboard , which allowed for redundancy and increased damaged resistance . Complement and crew requirements . The " Supremacy " was large enough to dock eight " Resurgent " - class Star Destroyers , six externally and two internally . It also crewed over 2 , 225 , 000 personnel , including officers , stormtroopers , gunners , vehicle engineers , factory workers , technical specialists , and communications staff . It likewise possessed at least 10 military staging areas , each of which can accommodate a full corps of more than 36 , 000 stormtroopers . The operations decks had floors of workstations filled with highly efficient operators . The vast majority of the crew were Sub - Adults ( ie , too young for active combat deployment ) , and fully indoctrinated into the First Order myth of a chaotic galaxy requiring a strong , unflinching order to control it . Largely because of its role as the First Order ' s headquarters , not only was it able to carry stormtroopers into battle , but it was also capable of fixing , harboring , and building various ships in the First Order Navy in its onboard hangar bays , two of which were large enough to even house and repair " Resurgent " - class Star Destroyers . Aside from these , it also carried production lines , shipyards , army training grounds and even R & D labs . The " Supremacy " also acted as one of the premier research labs and factories in the First Order , possessing industrial capabilities that rival that of even the most productive worlds under control of the regime , with its armored decks housing departments reserved specifically for the conception , research , and approval of new weapons and technology . It also housed well - stocked raw materials reserves , eight durasteel foundries , an asteroid mining complex for harvesting raw materials directly from asteroids fields , as well as state - of - the - art production lines . Training centers were present to indoctrinate young cadets into the military . As it carried all the supply lines , it also cannot be cut off from supply lines . Its capabilities were such that its destructive power was comparable to that of a full fleet , its production capabilities comparable to that of a planet , and acting as a testbed for the various military advances of the First Order . It also possessed a detention center near the stern , as well as a commons area , an assembly hall that can fit 200 , 000 personnel , as well as at least 346 laundry rooms . The majority of the crew quarters were placed within the various central " city " blocks of the ship . It also possessed at least eight droid manufacturing facilities , one of which , P - 3 , achieved the top rank , as well as a ground vehicle manufacturing zone . In addition , the tips of the wings were reserved for top secret labs and dangerous weapons tests , and also possessed communications hubs . The starboard wing possessed a crew transportation causeway with an integrated tram system . Bridge . Its main command bridge sat upon a massive structure sitting at the center of the ship , which had a similar design to that of the " Mandator IV " - class Siege Dreadnought , and to a lesser extent the " Resurgent " - class Star Destroyer . The bridge had access to displays that allowed for 360 degree views , thus allowing for lookouts over everything within the city - scape - like structures on the main " wing " of the destroyer . Hyperspace tracker and armaments . The " Supremacy " was able to track its targets through hyperspace using a combination of technological advances and brute - force data crunching . The Shipboard Tracking Control Complex boasted the data - shifting power of a planetary intel hub , linking its huge computer arrays to data banks loaded with centuries of combat reports and astrogation data . A static hyperspace field generated around the machines accelerated their processing power to unheard - of levels . A target ' s last known trajectory yielded trillions of potential destinations , but the system could assess them with terrifying speed . This capability of tracking ships via hyperspace routes had its roots from the Tarkin Initiative . The ship , owing to it being the central command ship , forwarding base , and the proverbial brain of the First Order ' s entire forces , was also entirely self - sufficient , to the extent that it did not need to worry about supply shortages . In addition , the vessel possessed thousands of heavy turbolasers , anti - ship missile batteries , heavy ion cannons , and tractor beam projectors . The bow of the ship possessed ten heavy turbolaser towers . Its power was such that only the Death Stars and Starkiller Base rivaled it . Its communication complex monitored the holonet traffic throughout the galaxy to identify trends and weaknesses that the First Order could exploit . As such , they also dispatched orders to various agents operating within both New Republic and independent space . History . Construction . The ship was built by the First Order at staggering cost within a secret birthplace within the Unknown Regions to act as the official capital of the First Order at the order of Snoke . Although various officers as well as allies of the First Order argued for a planet to act as their capital , Snoke insisted on using the " Supremacy " as the main capital of the group , refusing to designate it to a world either under direct First Order control or in the Unknown Regions , at least not until they succeeded in their goal of bringing the entire galaxy under their control and restoring the old Galactic Empire , as he aimed to restore the territory formerly belonging to the Galactic Empire and build upon it . Cold war . Upon being completed , the " Supremacy " was kept hidden in the galaxy ' s Unknown Regions to keep it from being discovered . During the cold war , Snoke preferred to issue commands from this vessel to his minions . In order to ensure it was not discovered , Snoke also had it hidden among the brightest stars within the Unknown Regions . However , the Resistance nonetheless suspected the existence of the ship , nicknamed " Snoke ' s Boudoir " and tried to investigate the veracity of its rumored existence among the underworld , although even the more cynical members of the Resistance could not imagine just how gargantuan the ship was . Prior to his defection to the Resistance , FN - 2187 spent some time aboard the " Supremacy " whenever his stationed vessel , the " Resurgent " - class Star Destroyer " Finalizer " , was docked with the " Supremacy , " doing patrol routes and basic duties . To his regret , he was unable to inform the Resistance of its existence prior to their encounter with it , as time simply did not permit it . After the Hosnian Cataclysm , however , Snoke , determining that the time was right to unveil himself , proceeded to unveil the ship to the unsuspecting galaxy to pursue the Resistance . Attack on the Resistance fleet . The " Supremacy " participated in pursuit of the fleeing Resistance fleet . Under the command of General Armitage Hux , the " Supremacy " followed the fleet , knowing they could not jump to hyperspace , as the " Supremacy " could trace them with new technology and that if the Resistance continued to run , they would eventually run out of fuel . Utilizing single heavy turbo laser batteries near the forward hangars , the " Supremacy " bombarded the Resistance as they ran , destroying a cargo ship immediately , a medical frigate and a corvette when they ran out of fuel . Eventually , the Resistance evacuated their flagship , " Raddus " in transports . Hux then ordered the transports targeted instead of the flagship . While many transports were destroyed , in Hux ' s haste to stop the Resistance from fleeing to Crait he neglected to realize that Vice Admiral Amilyn Holdo was preparing a jump to hyperspace while aimed directly at the " Supremacy " . Realizing too late what was about to happen , Hux could only watch as the " Raddus " sliced right through the right wing , destroying several escorting " Resurgent - " class Star Destroyers in the process as well . However , a large portion of the First Order ' s leadership was able to escape due to preparations set about by Snoke . In addition , the ship itself , while significantly damaged from the attack , nonetheless remained functional , even though it was thought that the flagship was doomed . Behind the scenes . The ship was first unveiled via the BB - 9E App - Enabled Droid toy by Sphero by going through various areas and collecting data . The initial data erroneously claimed that the length of the " Supremacy " was over 60km , although the confusion was rectified by Pablo Hidalgo on his Twitter feed where he clarified that the measurement was actually referring to the ship ' s width via its wingspan .
