However , the " Unity " was overwhelmed by the bombardment unleashed by the Separatist capital ships , which destroyed the vessel . Description . The " Unity " was a " Venator " - class Star Destroyer that was part of the Republic Navy during the Clone Wars between the Republic and Confederacy of Independent Systems . Manufactured by Kuat Drive Yards , the " Unity " was 1 , 137 meters long , and was equipped with eight engines , a hyperdrive motivator , and a pair of command towers . The " Unity " had an armament of fifty - two laser cannons , eight DBY - 827 heavy dual turbolaser turret s , two medium dual turbolaser cannons , four proton torpedos tubes , and six tractor beam projectors . The Star Destroyer was also equipped with deflector shields , but these would collapse under sustained enemy turbolaser fire . History . In 21 BBY , a large Confederate fleet — under the command of cyborg General Grievous — launched an invasion on the Republic aligned - planet of Dorin , the homeworld of the Kel Dor species . The Separtist fleet — composed of Grievous ' s command frigate , two " Lucrehulk " - class Droid Control Ships , and sixteen " Munificent " - class star frigates — began to lay waste to Dorin , killing many Kel Dor loyal to the Republic . When the Republic received word of the Separatist attack , they formed a task force to reinforce Dorin . Led by Jedi Generals Anakin Skywalker and Plo Koon and Admiral Wullf Yularen , the task force included the " Unity " , Skywalker ' s flagship , the " Resolute " , and seven other " Venator " - class Star Destroyers . The " Unity " and the rest of the Republic fleet soon departed from the Republic capital of Coruscant . However , the fleet ' s movement was discovered by Separatist intelligence , which informed Grievous of the incoming Republic flotilla . In preparation for the upcoming battle , Grievous recalled his battle droids from Dorin ' s surface and prepared his fleet and droid starfighters for combat . The " Unity " and the rest of the Republic task force jumped out of hyperspace over Dorin and engaged Grievous ' s forces in the space above the planet . Both fleets began launching starfighters and trading turbolaser strikes with each other . However , the " Unity " deflector shields , under concentrated fire from the Confederacy ' s frigates ' heavy turbolasers , failed , causing the " Unity " to break apart in space . Despite the loss of the " Unity " , the Republic flotilla managed to defeat Grievous ' s forces , causing the Confederate General to flee the battle and freeing Dorin from the Separatists . Behind the scenes . The " Unity " was first indirectly mentioned in a script reading by the main characters of voice - acting cast at the October 2009 " Star Wars " Fan Days III convention . In the script reading , the Dark Acolyte Asajj Ventress reports to General Grievous the Republic fleet ' s — and therefore the " Unity " — departure from Coruscant . The " Unity " later appeared in the " Starfighter " mini - game of the 2010 , in which the Star Destroyer was destroyed midway through the Battle of Dorin .
