Battle of Nocto The Battle of Nocto marked the final engagement between the Rebel Alliance and the Empire ' s Task Force " Vengeance " . It was the last - ditch attempt of Admiral Wooyou Senn to destroy the Alliance shipyard in the system with the meager remainders of his task force . The battle . Having raided and worn down Senn ' s Task Force " Vengeance " during the past few weeks , the Alliance did not expect the admiral to know where the vital shipyard " Calenz " was located . It came as a big surprise to the Rebel forces in the Airam sector when the Super Star Destroyer " Vengeance " , flanked by the Imperial Star Destroyer " Rage " , dropped out of hyperspace in the Nocto system . Due to a miscalculation on Senn ' s part ( or possible inexact intelligence on the precise location of the facility ) both capital ships reverted to realspace well beyond weapons range , which bought the Rebels crucial time to scramble both Rogue and Green Squadrons . Only minutes after the starfighter launch , the " Rage " corrected Senn ' s tactical mishap by performing a microjump , effectively ending up on the opposite side of " Calenz " and forcing the Rebel starfighter squadrons to split up in order to defend the facility . Calamari Cruiser " Liberty " reacted to the distress signal from " Calenz " and reached the system soon enough to position itself between Senn ' s Star Dreadnought and the shipyard . However , Rogue and Green Squadrons were effectively tied up by the Imperial fighter defenses , and a few TIE / sa bombers managed to unleash their payload upon the shipyard . The Imperial attackers dealt enough damage that " Calenz " was seriously damaged or destroyed before the Rebels could rally to fight off the bomber swarms . Simultaneously , the Super Star Destroyer launched a squadron of Gamma - class ATR - 6 assault transport s armed with heavy rockets . Senn intended to destroy , once and for all , the Mon Calamari warship that had plagued his sector operations . Against great odds , Green Squadron , in conjunction with kamikaze attacks by three allied Airam " Dreadnaught " - class cruisers , managed to knock out the Super Star Destroyer ' s bridge deflector shields , at which point the Airam corvette " Thunder " , loaded to bursting with space bombs , dropped out of hyperspace with the intention of ramming the " Vengeance " ' s bridge — a task in which it succeeded , despite taking heavy damage at the hands of the Star Dreadnought ' s gunners , killing Admiral Senn on the bridge and heavily damaging the vessel . The suicide run left only a small amount of armor to break through for Green Squadron . Both the " Vengeance " and the " Rage " are believed to have been destroyed at the hands of the Rebel forces , but the Alliance shipyard was also lost . Aftermath . The complete annihilation of Task Force " Vengeance " ' s remainders was a significant blow to the Galactic Empire . The Empire had lost at least twenty - five capital ships over the past several weeks , including most or all of their starfighter complements and the reinforcement fleet sent to assist Senn . The remoteness of the Airam sector meant that the Empire was not likely to send another expedition force of significant size to pacify it , thus ensuring both the independence of the Airam Clans and a safe haven for the Rebel Alliance , where they could regroup and rebuild their strength . However , it is uncertain whether the Rebels maintained their hard - fought stronghold in the Airam sector , as the shipyard " Calenz " was regarded as mission - critical by Alliance forces during the Battle of Nocto . It is possible that its destruction , along with the heavy damage done to the " Liberty " and the destruction of four Airam capital ships , forced the Rebels to withdraw and regroup elsewhere , making the Airam campaign largely a wash . At any rate , the Airam sector is not mentioned beyond the Battle of Nocto as a stronghold for either the Rebel Alliance or the Galactic Empire , nor is the status of the Airam Clans after its bloody events currently known . Behind the scenes . The actual canon outcome of the Battle of Nocto is disputed , because the two " " campaigns ( for the Empire and the Rebellion , respectively ) have alternate endings depending on which side the player is on . One interpretation is to assume that all missions and cutscenes from both campaigns are canonical , and that all mission objectives were achieved ( as so to advance the storyline of the campaign on to the next mission , and so on ) , rendering all engagements ' outcomes known with the exception of the Battle of Nocto . In the game itself , it is either the " Vengeance " or the shipyard which is destroyed by the player ' s forces , with the other required by mission goals to survive . Following the standards adopted for handling the rest of the missions , this article assumes that both sides succeeded in destroying their primary targets , which would result in a draw . However , text seen by the player after the Imperial victory includes a formal statement that Rogue Squadron was wholly eradicated , thus clashing with canon . Accounting for the destruction of most of the attacking force and the survival of Rogue Squadron , the outcome of the Battle of Nocto thus appears more akin to a Pyrrhic victory for the Rebel Alliance . Considering the stated importance of the shipyard , it is possible that the battle was a tactical stalemate , but the defeat of Task Force " Vengeance " by an outgunned Rebel / Airam fleet renders it a strategic triumph for the Rebellion .
