Command center Command centers were military support buildings used by fighting forces throughout galactic history . History . Command centers were support buildings used to construct support units for fighting forces throughout galactic history . These buildings would construct units such as droid and organic laborers , and medics . In addition , these buildings also researched technology for unit upgrades . They also served as drop - off points for resources such as food , carbon , nova , and ore . It cost 300 units of carbon and 100 units of ore to construct a command center . Units were able to garrison inside the structures for healing and repair , and could fire at hostile units . Gungans and the Royal Naboo Security Forces on the planet Naboo build command centers , as did the Trade Federation . The two sides of the Clone Wars , the Galactic Republic and the Confederacy of Independent Systems had their own versions , as did the Wookiees on Kashyyyk . Later , during the Galactic Civil War , the Galactic Empire and the Rebel Alliance both used command centers . Command center types . Galactic Empire . The command centers used by the Galactic Empire were gray and blue on the outside , with a sphere on top and a manning tower on the leftmost corner . It was manned by droids including the 2 - 1C medical droids , the ASP - 7 labor droid , and various Viper probe droids . When the Command Centers are first constructed , they were bare , often being little more than girders . In addition , it usually necessitated ladders and had multiple wiring to the southern corner of the base . Further construction eventually led to a more stable appearance , having some ramps as well as the top of the base being covered with and bar windows for the northern portion of the Command Center . In addition , bridges were constructed connecting the Northern corner with the Eastern and Western corners , with the latter having a higher tower , and some barrels underneath its bridge . The generator also necessitated less need for wires connecting across the base . The Command Centers , upon further refurbishments , allowed for some walls to be constructed . In addition , the northern portion was improved , allowing for a small circular window and some stairs . The southern portion of the base also included some barriers , and the bridges were now full - scale platforms . Portions of the East and West towers were also completed . Eventually , the Command Centers , upon completion , possessed full blast gates for entry within the premises . The stairs were also replaced with a turbolift elevator , and the design for the top portion of the northern area was also radically changed to be spherical in nature . The walkways leading to the East and West portions of the Command Centers were also fully enclosed within the walls . Galactic Republic . Depending on its state of construction , the Grand Army of the Republic ' s command centers ' coloring was different . However , it overall possessed trace amounts of brownish - yellow and gray colors . It was manned by droids including the IM - 6 battlefield medical droid s and Kaminoan droid s . When the Command Centers were first constructed , their design was primarily simple , containing simply a two - way open - door garage that were accessible via ramps with a landing platform at the top . Some external generators were also located nearby . Further construction eventually led to a more complex appearance , having the landing platform largely covered by a large trapezoid building , and its edges having circular supports added on . The external generators are also removed , alongside the ramps leading down to the garages . The foundation was also somewhat more stable and expanded . The Command Centers , upon further refurbishments , made most of the base into a trapezoid - like structure , with circular dais at the corners . In addition , the upper part of the base had its trapezoidal building replaced with twin buildings that had some connection via a small connection passageway . The circular supports were also expanded , indicating an intention to connect the two parts of the Command Center together . Eventually , the Command Centers , upon completion , had its entire base converted into a trapezoid , with actual blast doors sealing off the garage areas . In addition , the dais were converted into towers , the upper half of the building was made almost cube - shaped , and the circular supports now hang as pill - shaped objects at each corner . Confederacy of Independent Systems . Due to the Geonosians playing a key role in the Confederacy of Independent Systems ' makeup and leadership , the CIS ' s command centers were made of Geonosian stone , and resembled a building , with a circular arena - like area in the center . It was manned by ADK - 25 - MED medical droid s and Geonosian workers . When the Command Centers are first constructed , they simply resembled a dome with some curved / conish buildings . In addition , they also were in the process of erecting another building in the process , seen with the plowed surface near the south . Two orbs were also nearby . Further construction eventually led to a more polished appearance , with the curved / conish buildings strongly resembling pills . In addition , braces were also placed on the domed building , and the plowed area also became a crevasse of sorts surrounding the arena . Supports were also implemented between the domed building and the rightmost pill building . The Command Centers , upon further refurbishments , allowed for two additional buildings to be constructed . Many of these buildings were also significantly taller and were almost spire - like in nature . In addition , the domed building underwent a significant redesign , featuring a sloped base as well as thorny outgrowths at the top , as well as a much larger door . At least one additional support was also constructed , and the crevasse was much deeper , with the arena base being narrower . An additional orb was also constructed . Eventually , the Command Centers , upon completion , possessed multiple supports for the buildings . The main building was also castle - like , with significantly larger thorny outgrowths than before , and was more pillar like . The arena also ended up having its base completely removed . The other buildings also had spire - like designs , with one having a beak - like appearance . Gungan . Similar to other Gungan buildings , the Gungan Grand Army ' s Command Centers utilized electrostatic bubble generators with a pinkish coloration , although regardless of the form , only one was most prominent . Similar to the Wookiees , their command centers aren ' t manned by droids . Instead , Gungan doctors and Glurrgs manned the buildings . When the Command Centers are first constructed , the primary ( and by this point , only ) electrostasis bubble building required constant support , with at least three support struts on top . It also possessed three arches . There were also multiple platforms , some of which required scaling to reach the main gate . Further construction eventually led to a more stable appearance , thus not needing any support struts directly on the bubble generator . Two more electrostatic bubbles were also developed , which were tiny especially compared to the primary bubble . A lot of the tiny platforms were also removed , and its gate made more elegant with a ramp . The Command Centers , upon further refurbishments , created 16 additional bubble generators , while the two earlier bubble generator additions grew larger and more egg - shaped , although still not as large as the primary bubble . The support struts also became a bit more complex as they hugged the main building . In addition , the ramp was done away altogether in favor of a two - way path leading to the gate , with the gate itself being more elegant . Eventually , the Command Centers , upon completion , was nearly completely covered , with the two secondary bubble generators being moved to indoors and the tertiary bubble generators being replaced with stands . The struts also reached the top of the primary bubble generator . Rebel Alliance . It was circular with some towers and a dish turret . It was manned by droids including the 2 - 1B and the Rebel Astromech Droid series R2 - D5 . When the Command Centers are first constructed , they were bare , often being little more than girders and basic supports . This was especially true with the circular roof . In addition , it usually had a little more than a small , basic holoscreen for reporting on activities of the Alliance . It was also hooked up to external generators . Three pylons were also already in place . The main platform was also tiny , and a square - shaped satellite dish was nearby . Further construction eventually led to a more stable appearance , with the circular roof being somewhat more stable and nearly complete . The floor area was also expanded and its holoscreen was upgraded to be more towering . The supports were also covered with armor . More powerful external generators were connected to the left and right of the base . The command center also replaced its satellite with a circular dish . The Command Centers , upon further refurbishments , managed to have its roof base to not have holes in it . The supports also ended up letting loose some of the armor and placing additional struts . The holoscreen was replaced with a holoprojector with various holoscreens moved to the opposite side of the base . Containers were also found nearby as well as a generator . A ramp was also included . Eventually , the Command Centers , upon completion , possessed a holoprojector pod that removed the starry features when displaying information , and removed most holoscreen terminals in favor of an amphitheater design . The roof also was fully complete , featuring curves . The Command Center also had a pit within the interior , and the interior itself is accessible via three ramps . The generator was also left armored , and the containers became additional power generators . Royal Naboo . The Command Centers generally resembled a Naboo villa , with a water fountain and an interior circular garden . It was manned by droids including the Royal med droid and the PKN - 49 worker droid . When the Command Centers are first constructed , they were tiny , only possessing a small , six - faced triangular roof , a fountain , and an ivy - covered rafter covering on the left and right sides each . It possessed three stairwells , one directly in front of the Command Center , and the remaining two near each of the ivy - covered rafters . Each of the stairs also had a pool of water near them . In the case of the main stairs , it was directly in front of the stairs , and in the case of the auxiliary stairs , it was next to them . Further construction expanded the roof , with the ivy - covered rafters being replaced and combined with the lower portions of the roof " faces , " resulting in a bending roof face . In addition , the main stairwell was eliminated and replaced with an edge . The remaining stairs are kept intact , and the main stairs are instead located around the larger fountain , for easier access . Ivy was also growing on top of the rooftops . The Command Centers , upon further refurbishments , allowed for some more pillars to be constructed , tightening the defenses . The roof was also for the most part replaced with the typical domes of the Naboo architecture . The stairs are also made more elegant , and the pools of water near the other stairs were also expanded to have an arch underneath to allow for more water flow . The stairs also returned to the front of the Command Center . Naboo statues were also added to the front of the building . Eventually , the Command Centers , upon completion , possessed full gates for entry within the premises to the main building from all three sides , with the building interior being completely enclosed . As such , the roof also was in effect similar to the first incarnation , albeit now featuring one of the domed architecture from Naboo at the center . The plants on top of the roof are also fully removed . Trade Federation . It was brown , and primarily arch - shaped , with a tower . Although the Trade Federation itself was primarily manned by droids , the command center was manned by MED - 47 medical droids and OX9 labor droids . When the Command Centers are first constructed , it was largely bare , with the tower being somewhat narrow . In addition , the only parts of the hull that are fully complete are parts of the roof . The main generator , inside the tower is also vulnerable . Further construction had most of the open areas patched up , with more cables connecting the core of the command center . Some vital areas are also established within the arched roof of the building . The Command Centers , upon further refurbishments , Has virtually all of the hull completed , with only the generator and a tiny bit of the top being exposed . In addition , the tower also has its top replacing the tuning fork - style decoration for a more spearhead - like connecting flap . Eventually , the Command Centers , upon completion , possessed fully armored hulls , even blocking access of the tower generator from the outside . Wookiee . Its design was primarily made of a combination of wood and metal patchworks . its most notable feature was a curved portion . Unlike most other command centers throughout various ages of the galaxy , it was not manned by droids . Instead , various Wookiee villagers and medics manned it . When the Command Centers are first constructed , the only aspect of the building that was remotely constructed was the curvature and a small hut , which were primarily girders with some metallic patchwork . Its power generator was likewise external . Further construction eventually led to it having a more complete appearances , the girders being covered by wooden walls , and the roofs having more metallic patches . The small hut also increased in size and was now directly connected with the building . A manning tower was also beginning construction . The Command Centers , upon further refurbishments , had most of the wooden walls covered up . The hut portion also had more metallic coverings and had circular ramps . The tower also was mostly complete , with some searchlights on top . Eventually , the Command Centers , upon completion , possessed a staircase to the main building . In addition , additional flaps to the rooftop of the smaller building were added . The tower aspect of the building was fully completed , and included a viewscreen . The command center also had its generator completely covered . Between 39 and 36 BBY , a team of Wookiee colonists , had rediscovered Alaris Prime , and proceeded to colonize it . The Wookiees , upon arriving at Alaris Prime , then proceeded under Qui - Gon Jinn ' s guidance , to create a command center on the colonized planet . Jinn then proceeded to guide five Wookiee workers to gain various resources and food . Afterwards , they then conducted a drill of defending the base in case Gundarks attacked the command center . Shortly after Chewbacca ' s arrival at the command center , the base was attacked by the Gundarks for real , and the Wookiees then proceeded to defend the command center for real from the drill they had earlier conducted . Afterwards , they sustained the base from ore and nova crystal deposits . Behind the scenes . Command centers appear in the 2001 video game " " and its 2002 . Some missions start with command centers and in other missions players must build one . In multiplayer , the games start with a command center already built .
