Lucrehulk - class battleship The " Lucrehulk " - class battleship was the primary capital ship of the Trade Federation ' s Trade Defense Force . Most " Lucrehulks " were modified from enormous cargo haulers . Upgraded and modified versions were later used by the CIS Navy , the Separatist holdouts , the Alliance to Restore the Republic , the Corporate Sector Authority and the Killik Colony . Characteristics . At over three kilometers in diameter , the enormous vessel resembled a donut - shape that was missing a section of its circumference and it had a central sphere that contained the ship ' s bridge and reactor assemblies . The front void of the craft held two mammoth docking bays on either side , which were lined with forward docking claws . These gigantic cargo vessels had been built for many years by the Trade Federation to haul cargo between planets and were an important asset to their enterprise . Housed in the stern of the main body were the main reactors , each connected to one of the three main engines , as well as to secondary engines and each other . The central sphere housed its own reactor / power generator assemblies . Lining the equatorial bands in batteries of three , were quad turbolaser cannons capable of rotating inwards when not in use . Their limited coverage of the hull made the early battleship models vulnerable , and made them rely more on the massive number of starfighters carried to defend the ships against enemy starfighters . This was , however , rectified with later ships whose armor and shields proved too strong for starfighter firepower , the fact becoming quickly apparent at the Battle of Naboo . The pre – Clone Wars models of the battleships did have major defense flaws , as Anakin Skywalker was able to fly his starfighter into the hanger of a Droid Control Ship and destroy the main reactor by accident . The resulting explosion destroyed the battleship and ensured a Naboo victory . Clone Wars – era battleship . " Lucrehulk " - class battleships that fought in the Clone Wars had less trouble with weak spots , as they were augmented with gun batteries and much stronger shielding . Batteries of long gun s and heavy gun s complemented the additional quad turbolaser batteries added to the " Lucrehulk " superstructure when the war erupted . Each ship was also now so powerful due to the increased amount of power devoted to offensive and defensive systems that a whole flotilla of Republic Star Destroyers was needed just to bring down a " Lucrehulk " s shields . The Clone Wars refitted models were true battleships and were among the most powerful ships in the Confederate Navy . Due to their firepower and strong shielding and armor , and large starfighter complements , these battleships were often used as command ships and as blockade vessels . History . Origins . When the Trade Federation began creating its military , the Executive Board realized the need for large cruisers to transport their weapons across the galaxy , battleships to defend against starfighter attacks , and flagships for controlling their vast legions of battle droids . Reluctant to spend the credits necessary to construct and purchase a fleet of military vessels , the Trade Federation began modifying a portion of its many thousands of " Lucrehulk " - class freighters into warships . Their early navy had about 10 % of all " Lucrehulk " s converted to battleships and by the battle of Naboo , it was estimated that 35 % of the class had undergone refitting . Invasion of Naboo . The Trade Federation used a substantial fleet of " Lucrehulk " - class battleships to enforce the invasion of Naboo , led by the flagship " Saak ' ak " . The most important vessel in the Trade Federation ' s blockade was the " Lucrehulk " - class Droid Control Ship " Vuutun Palaa " . When the rest of the blockade dispersed after Naboo was successfully occupied , the Neimoidians left the Droid Control Ship in orbit to coordinate their droid forces . The Control Ship was later destroyed by the young Anakin Skywalker , resulting in the deactivation of the Droid Army . After the Invasion of Naboo , the Republic ordered the Trade Federation to disband its military forces . The crafty Trade Federation pretended to comply with this command by apparently disassembling most of its battleships , only to transform their centrispheres into detachable core ships capable of carrying supplies as well as increasing the battleship ' s armaments . In 27 BBY , two of these vessels were used to try to destroy " Outbound Flight " . The Chiss Commander Thrawn destroyed one of the " Lucrehulk " s , allowing the other to surrender . The Clone Wars . " Lucrehulk " - class core ships were used during the Battle of Geonosis , where they carried legions of battle droids . In retreat , the Core Ships were found to be able to reattach themselves to the outer ring . These vessels saw continued use during the devastating Clone Wars , transporting military equipment and troops to countless worlds , and engaging Republic fleets in combat . During the wars , the " Lucrehulk " - class battleship received a massive upgrade in terms of firepower , with the addition of hundreds of long guns , quad guns , and heavy guns dotting the surface of both the core ship and the surrounding cargo arms . They , along with the other capital ships of the Confederate Navy , also proudly wore the colors and insignia of the Confederacy . A few dozen participated in the attack on Coruscant towards the end of the war . Legacy . During the Imperial Period , some militarized " Lucrehulk " s remained in operation , fighting on the side of Separatist holdouts or early Rebel Alliance units . A few battleships kept in Imperial surplus stock were also sold to the Corporate Sector and to wealthy merchants . Other ships were dismantled and sent to garbage dumps like Raxus Prime . Several captured " Lucrehulk " s were pressed into service in the Imperial Navy and used to host flight schools for military fighter pilots . Several " Lucrehulk " s , belonging to an unknown party , were also involved in a skirmish with Rebel forces . One of several Alliance " Lucrehulk " s , the " Fortressa " served as a starfighter carrier , carrying a complement of hundreds of T - 65 X - wing starfighter s . In 0 BBY , it participated in an assault on the first Death Star and was destroyed by the battle station ' s superlaser . In 36 ABY , dozens of " Lucrehulk " - series freighters were appropriated by forces allied with The Colony and used as carriers for Dartship swarms during the Swarm War . Behind the scenes . " Lucrehulk " - class battleships first appeared in 1999 with the release of and its tie - ins . It has since appeared in every movie of the prequel trilogy . George Lucas wanted the battleship to have a retro - saucer look , but felt it needed a distinct sense of front and rear . Doug Chiang achieved this in early concept art by adding the antennae and docking section to one side , and a set of engines to the other . Lucas himself added the " bridge ball " to the center for the finished design . Battleships have appeared in LEGO form in the 2005 video game " " and in the 2012 young readers book " . "
