Devastator The Devastator was an " Imperial I " - class Star Destroyer of the Imperial Navy famous for its participation in the capture of the " Tantive IV " and as Darth Vader ' s flagship for a time . It later participated in the Imperial victory at Hoth and was destroyed during the decisive battle fought at Endor . Description . The " Devastator " was 1 , 600 meter s long , the standard length for an " Imperial I " - class Star Destroyer . As such , it was initially armed with turbolaser batteries , ion cannon s , and several tractor beam projectors . Upgrades . Several dozens of time s in its service life , the " Devastator " was structurally altered from its original design to include the latest weapons and systems , which kept it more than competitive with the battleship s that were commissioned later . Unlike some other " Imperial I " - class Star Destroyer s , such as " Lawbringer " and " Relentless " , the hangar s within " Devastator " ' s ventral docking bay were split into two smaller sections , and the aft side featured a cover , so that the bays behind weren ' t visible . Additionally , its tractor beam targeting array with diagonal support beams ( located between its two deflector shield generator domes ) being replaced with a communications tower with vertical support beams . History . Early Years . The " Devastator " was the last of the " Imperial I " - class Star Destroyers to lumber out of Kuat Drive Yards before the facility began producing the " Imperial II " - class . Despite this , it was still considered a state - of - the - art warship , and had undergone numerous retrofits to keep it comparable with newer ships of the line . In 5 BBY , fourteen years after the establishment of the Galactic Empire , the " Devastator " was the flagship of Lord Tion . Under the Sith . Scarif . However in 0 BBY , it now belonged to the Sith Lord Darth Vader , who used it in his struggle against the Rebel Alliance . Appearing over the planet Scarif near the conclusion of the Battle of Scarif , the arrival of the " Devastator " proceeded to cut off the escape of the Alliance Fleet , immediately destroying a GR - 75 medium transport by colliding with it , and disabling several ships , including the Rebel flagship " Profundity " which had received the plans for the Death Star . After boarding the " Profundity " , Vader proceeded to cut through Rebel trooper s who were delivering the plans . Vader failed , and the plans were delivered to Leia Organa , onboard the " Tantive IV " , a CR90 corvette that was docked onboard the " Profundity " . Fleeing at the last second , the " Tantive IV " escaped from the system and Vader pursued the starship in the " Devastator " . Tatooine . Arriving over Tatooine , a brief skirmish ensued over the planet , resulting in the Star Destroyer successfully capturing the " Tantive IV " . Imperial troops boarded the enemy ship , and the " Devastator " also targeted and destroyed any escape pod s that were launched in order to ensure none of the Rebels escaped . The sole exception was R2 - D2 and C - 3PO ' s pod — which even then was only because Imperial Gunner s did not detect any life signs in the pod , and dismissed it as a malfunction . The Cylo Incident . Vader used the " Devastator " to track Cylo ' s fleet of Whale - ship s in the Crushank Nebulae , courtesy of information from the doctor ' s colleague Thlu - Ry . As the Star Destroyer approached the nebula e , many of the abominations fled . This caused Vader to lead the chase in his TIE Advanced , supported by many TIE / ln starfighters . However , Cylo ' s flagship broke off from the main group , and attacked the " Devastator " with an ion pulse . With the ship disabled , Vader flew his TIE into Tulon Voidgazer ' s ship , just before the fleet could jump to hyperspace . They emerged over Kuat , the construction site of the " Executor " - class Star Dreadnought " Executor " , which was to be under the command of Grand General Cassio Tagge . Cylo took over the Super Star Destroyer , but was soon killed by Vader , along with all of his abominations and staff . Due to Tagge ' s trust in Cylo , he was demoted by Emperor Palpatine , then killed by Vader . The " Executor " was given to Vader for defeating Cylo . New Command . With the transfer of his flag , Admiral Jhared Montferrat took command of the " Devastator " . However , the legendary vessel remained a part of Death Squadron , Vader ' s personal flotilla . C - 3PO . Task Force 99 , an elite Stormtrooper squad , used the " Devastator " to interrogate C - 3PO after he was captured during the siege on Tureen VII . Although Vader wanted the droid destroyed , Kreel felt it would be in the groups best interests to use him as bait to lure the Rebellion to rescue him . Hoth . Under Montferrat ' s command , the " Devastator " notably participated at the Battle of Hoth , a clear Imperial victory , where it destroyed a transport . Endor and Destruction . The " Devastator " , the pride of the Death Squadron , met its fate at Endor , during a battle which the Emperor had meant to be the end of the Rebellion . The ship , still commanded by Montferrat , stood between Blade Squadron , a group of Rebel B - wing pilots and the Death Star II . Ultimately , the ship was destroyed when two of those pilot s , Gina Moonsong and Braylen Stramm , caused a chain reaction of explosions that led to the systematic demolition of the Star Destroyer . Commanders and crew . Prior to the destruction of Alderaan , the " Devastator " was the property of Darth Vader himself . As of the Battle of Hoth , it was commanded by Jhared Monteferrat , who held the title of admiral when the ship was destroyed during the fight over Endor . The senior ISB officer onboard was Captain Ronnadam .
