Space Battle at Kuat The Space Battle at Kuat was an operation performed in 0 BBY by Rebel Alliance Captain Raymus Antilles to lure the " Imperial I " - class Star Destroyer " Tyranny " away from the planet Fresia , where four prototype T - 65 X - wing starfighter s were being stored . During the battle , five CR90 corvettes , including the " Sundered Heart " , commanded by Antilles , raided the Imperial shipyards orbiting Kuat , destroying multiple unfinished ships while the Imperials scrambled to rally reinforcements . The mission was a success for the Rebels , who withdrew into hyperspace soon after the " Tyranny " arrived . Prelude . During the early days of the Galactic Civil War , the Galactic Empire decided to nationalize the independent Incom Corporation , as it had done with other organizations before . However , much of the design and research teams of Incom strongly disagreed with this decision , to the point where many of them decided to defect to the Rebel Alliance in 0 BBY . It was through these defectors that the Rebellion learned of a facility on the planet Fresia holding the four prototypes of Incom ' s newest starfighter design : the T - 65 starfighter , later known more commonly as the " X - wing " fighter . In 0 BBY , the Rebel Alliance , in dire need of a new starfighter design to replace the aging Z - 95 Headhunters that were in common use throughout the Rebellion at the time , dispatched a force led by Captain Raymus Antilles to secure the prototype X - wings from the Empire . However , when Antilles and his task force entered into the Fre ' ji system , they detected the " Imperial I " - class Star Destroyer " Tyranny " in orbit around Fresia . This caused a serious complication : with the " Tyranny " in orbit , the task force was unable to approach the planet . The battle . Antilles , in his modified CR90 corvette , the " Sundered Heart " , led four flanking corvettes to perform a hit - and - run raid on the orbital shipyards of the planet Kuat in order to lure the " Tyranny " from its new station at Fresia back to its usual station above Kuat . Imperial resistance at Kuat was light , and the Rebel corvettes easily defeated the defending TIE / LN starfighter s and " Tartan " - class patrol cruisers . Many orbital resource containers were strewn about the half completed starships there , and the Rebel corvettes targeted the containers , which then exploded and destroyed the surrounding shipyards . The " Tyranny " originally refused several times to respond to distress calls from the shipyard ' s communications officer . When the Rebels destroyed the last shipyard , the officer activated Emergency Code Zero . In response , the " Tyranny " returned to Kuat to render aid to the Imperial defenders . The commander of the " Tyranny " warned the Comm Officer that by invoking Code Zero , he had altered Vader ' s plans and will answer to him if the code was invoked lightly . The Star Destroyer came out of hyperspace with the shields down , giving the small Rebel raiding force a chance to damage the warship before escaping . Aftermath . With the devastation of the Kuat shipyards and the damaging of the " Tyranny " , the Rebels believed that Fresia would be left unprotected , allowing them to raid the Incom facility . However , before the " Tyranny " had returned to Kuat , it had deployed numerous sentry drones to lock down the Fre ' ji system in its absence . When the Rebels detected this , it seemed certain that the mission to retrieve the prototype X - wings would have to be canceled . However , the protocol droid C - 3PO was able to devise a plan that would allow the Rebels to slip past the Imperial defenses . C - 3PO ' s astromech droid counterpart , R2 - D2 , would proceed to the planet Wayland , where he would steal the Imperial codes that would allow a Rebel team to enter the Fre ' ji system undetected . Antilles agreed to this plan and immediately dispatched both C - 3PO and R2 - D2 to Wayland with a large ground force to escort them . Behind the scenes . The Space Battle at Kuat is the first mission of the Rebel campaign in the 2006 LucasArts PC game " " . The mission is the first in a series of three missions that lead to the acquisition of T - 65 X - wing starfighters for use by the Rebellion . The battle was first identified as the " Space Battle at Kuat " in the game ' s , published by Prima Games .
