Home One / Legends Home One , also known as the Headquarters Frigate , was an MC80 Star Cruiser in the Alliance to Restore the Republic ' s fleet , famous for its role at the Battle of Endor and as one of Admiral Gial Ackbar ' s flagships . It was the namesake of the " Home One " type subclass and was noted as being the largest and most advanced of the Rebel Star Cruisers . Characteristics . " Home One " belonged to the Mon Calamari Star Cruiser line of warships , and like most Mon Cal ships , it had a long cylindrical hull . Blue - gray in color , it had a tapered nose , and a bulbous stern , and it lacked the flared wings seen on the MC80 " Liberty " type . In her original form , the " Home One " was an unarmed civilian vessel , designed for deep - space exploration , and her hull was strewn with a number of large observation viewports that would have been vulnerable in a military role . However , it is possible that , viewport bubbles notwithstanding , she was protected from the outset by the heavy hull plating and triple - redundant deflector shields that she would later carry in Rebel Alliance service . During the Galactic Civil War , the " Home One " was rebuilt to serve as a command ship , carrier and battleship . Her vast viewports were plated over , and she was outfitted with a heavy offensive armament . The hull contained twenty hangars , two of which were capable of handling larger vessels , these presumably being the large bay on the starboard side of the hull , and the main hangar on the ship ' s underbelly . Two smaller bays were visible on the port side of the hull , approximately opposite the large starboard bay . The secret squadron Gray Flight utilized a hangar with an aperture located in the " ceiling " of the room . The interior corridors , bridges and bulkhead s of the " Home One " were pristine white . The " Home One " was modified by Calamari technicians to be capable of splitting apart in three sections . The topmost section containing the main bridge and a forward section above the bow could separate from the main superstructure and function as additional warships or escape vehicles . The ship was powered by four M8 . 0 - StarDrive engine s and six M4 . 5 - StarDrive maneuvering engine s , a drive system also used on the " Liberty " type , although the thrusters of the two designs were arranged in different configurations : where the " Home One " had four large and six small nozzles , the " Liberty " had nine of varying sizes . " Home One " had a standard crew of 5 , 402 , in addition to 78 gunners . It could carry 1 , 200 troops and 20 , 000 metric tons of cargo The minimum operating crew for the vessel was 1 , 230 . As with all early Mon Calamari cruisers , most ship bridge controls could not be modified for use by Human hands , so the command crews were almost exclusively Mon Calamari , but the rest of the crew were a mix of all Rebel species : for example , Plourr Ilo served as a technician during the Battle of Endor . History . As with most Alliance - era Mon Calamari warships , the " Home One " began as a civilian vessel built at the shipyards of Mon Calamari . She was designed as an unarmed exploration vessel , used to investigate deep space and to make contact with alien species . When the Mon Calamari began to support the Alliance in earnest , the ship was selected for conversion into a warship , and became the flagship of the recently freed Ackbar . " Home One " became particularly important after the Alliance ' s defeat at the Battle of Hoth deprived Alliance High Command of a planetary headquarters , and she became the mobile base of operations of the Rebel leadership . As the flagship of Admiral Ackbar , Supreme Commander of the Rebel Fleet , the vessel was considered one of the most important assets to the Rebellion . " Home One " was one of the largest ships in the Alliance fleet at the Battle of Endor and Ackbar commanded the Alliance fleet from its bridge . X2 helped Ackbar defend the ship ' s reactor core from attacking stormtroopers . The vessel went on to serve as Ackbar ' s flagship for the next five years , serving as the home base of the famed X - wing unit Rogue Squadron and participating in numerous key battles , including the Seizure of Coruscant , the Battle of Bilbringi , and the Battle of Ciutric . Ackbar ' s flagship was constantly in use , due to the Supreme Commander ' s tendency to command important engagements personally . As a result , the vessel needed to be maintained at a constant state of readiness , which was achieved by repair yards in orbit over Coruscant . Over the years , however , more advanced Mon Calamari starships were developed , such as the MC80B and MC90 , and by 10 ABY , Ackbar was commanding the fleet from a new MC90 Star Cruiser , the " Defiance " . But the " Home One " continued to be deployed in front - line roles . She served as the command ship in the hunt for Leonia Tavira ' s Invid pirates in 11 ABY , leading a taskforce that included Rogue Squadron and two " Victory " - class Star Destroyers , and Ackbar continued to use the venerable Star Cruiser as his personal flagship throughout his tenure as Supreme Commander , so she did not leave service until 23 ABY at the earliest . Behind the scenes . Canon is inconsistent about the weapons array aboard " Home One " . The best - known ( and apparently most frequently stated ) armament consists of 29 turbolasers and 36 ion cannons , arguably a very light armament for a vessel of this cruiser ' s size and importance . However , the earliest known source to give the ship ' s armament , the 1984 first edition of " A Guide to the Star Wars Universe " , describes her as carrying 29 batteries of five turbolaser cannon each , for a more impressive total of 145 turbolasers and 36 ion cannons . Adding to the confusion , the " Star Wars Trilogy Sourcebook , Special Edition " gives " Home One " instead an armament of 48 turbolasers and 20 ion cannons , which had previously been given as the armament of a standard MC80 Star Cruiser . " The Official Star Wars Fact File 12 " cites the two contrasting armaments on consecutive pages . A more recent official source , " Starships of the Galaxy " , gives the " Home One " and its subclass 36 turbolasers , 36 heavy ion cannons and six tractor beam projectors . In the and a number of other early sources , the name " Headquarters Frigate " was italicized as if it were the ship ' s name , and " Home One " ( or " Home - one " ) was not , as if it were merely a Call sign for the ship , comparable to " Red Leader . " Some fans have wondered how a ship can be called both a " cruiser " and a " frigate , " but a possible real - world parallel is found in the United States Navy , where the term " frigate " was used for all but one of the large surface - combat warships built between 1950 and 1975 , the majority of which were reclassified as " cruisers " in 1975 . Direct scaling of " Home One " in " " implies a minimum length of approximately 2 . 5km , and some cinematic evidence suggests a length of several kilometers . This contrasts with the 1 , 200 - meter , 1 , 300 - meter and 1 , 400 - meter lengths given by Expanded Universe sources . " X - Wing Alliance " , which provides the source for the 1 , 400 - meter " Home One " , also gives a length of 1 , 500 meters to " Liberty " - style cruisers and calls both types " MC80a " s . The most - quoted size of 1 , 200 meters apparently originated with West End Games , and is often presented as the generic size of MC80 Star Cruisers . The " Return of the Jedi " script and novelization contradict these later sources by describing " Home One " as the largest of the Rebel Star Cruisers , corresponding to its visual appearance in the film . The game " " scales " Home One " at approximately 3 , 200 meters . The game shows the " Venator " , " Victory " , " Imperial " , and " Liberty " classes in nearly perfect relative scale against each other . " Character " vessels are sometimes larger than their counterparts , which suggests that " Home One " may not be to scale , though the scaling is consistent with its size in " Return of the Jedi " . LEGO made a set of the " Home One " called " Home One Mon Calamari Star Cruiser " released in August 2009 . The set focused on the briefing room and a hanger bay rather than the whole ship . In the " Rogue Squadron " games , the " Home One " docking bay often acted as the main area to select spacecraft for a mission , with the exception of missions relating to Yavin or Hoth , for which the Great Temple ' s docking bay and the Echo Base docking bays , respectively , acted as that area instead .
