Shipyard ( water ) Shipyards , sometimes referred to as docks , were military facilities used to construct ocean - going vessels , such as utility trawler s , frigates , and destroyers . It was used by the Gungans , the Rebel Alliance , the Confederacy of Independent Systems , the Grand Army of the Republic , the Galactic Empire , the Royal Naboo Security Forces , the Wookiees , and the Trade Federation . Known Shipyard types . Galactic Empire . When the Galactic Empire ' s Naval Shipyards are first constructed , they were an " I - shape " and were relatively bare , only composed of few walls and exposed generators and girders . The shipyard also possessed docking area entrances to the left , right , and bottom areas of the docks , as well as seven docks overall ( including the I - like structures ) . Further construction eventually led to a more stable appearance , with the wires not being exposed . The roof was also completed to have a sloping aspect down the spine of the shipyards . The southernmost area also possessed a gate . The Naval Shipyards , upon further refurbishments , fully enclosed all but the spine itself , which now possessed a full gate coming down into the water . The two sides also were sloped , similar to half - circles . Eventually , the Naval Shipyards , upon completion , had become towering over the prior models , and had its central gate open . The southern area also had a minor panel at the bottom . Gungan . Similar to other Gungan architecture , the Gungan shipyards utilized Hydrostatic bubble - like devices to allow for some structure , including for the actual docks . Rebel Alliance . The Rebels ' shipyards themselves were built inside the shipyard building , and was constructed with an " L - shape " entry / exit point . It possessed two communication satellite arrays . Royal Naboo Security Forces . The Royal Naboo Security Forces ' architecture was largely derived from Naboo architecture , and the docks themselves were " H - shaped " . Further expansions included a pangola and a balcony . Trade Federation . The Trade Federations ' shipyards utilized Neimoidian architecture , and had a manning tower at the top . The docks themselves were located underneath the actual building . Wookiee . The docks , at least in the initial stage , were T - shaped . In its first stage of construction , it had metallic stairs leading from the main control tower to the docks , and had two exterior hangars , one adjacent to each side of the tower . Eventually , the docks were given a bigger walkway , with the docks themselves being underneath the walkway . Confederacy of Independent Systems . Similar to most CIS installations at the time , it was based primarily on Geonosis architecture . When first constructed , the docks were partially submerged , with most of the development and shipments being haphazard . They eventually managed to merge them together , with their eventually elevating the docks . Its docks in its final state were of a T - shape , and were on elevated terrain . The ships exited and entered beneath a bridge , of which the bridge led to the docks and an entryway to the main facilities . Grand Army of the Republic . The shipyards were largely prismatic in design , and were defined by aquamarine and white colors . The docks and the main shipyard building were connected by a fine pole between the two , and were otherwise completely separated , although they eventually were connected by two iron angular beams , with the main building being expanded to include a tower with three circular knobs at the top .
