Bulwark Mark III The Bulwark Mark III , also known as the " Bulwark " - class battlecruiser , was a massive warship developed by TransGalMeg Industries using an old Techno Union battleship from the Clone Wars as a design basis . Equipped with extensive firepower , shielding , and carrying capacity , the 2 , 500 - meter Bulwark Mark III was ideal for large - scale operations , capable of inflicting damage equal to an " Imperial " - class Star Destroyer . During the Galactic Civil War , the Bulwark battlecruiser was one of the most heavily armored and durable vessels serving with the Rebel Alliance , while the SoroSuub Corporation ' s Sullustan Home Guard also utilized the ship in defense of the planet Sullust . Later , during the Yuuzhan Vong War , the New Republic employed several Bulwarks in an operation to help evacuate citizens from the beleaguered planet Rychel , which had fallen under Yuuzhan Vong attack , and again during a blockade to defend the planet Shramar from Vong invasion . Characteristics . Developed by TransGalMeg Industries , Incorporated , the Bulwark Mark III , or " Bulwark " - class battlecruiser , was a massive , 2 , 500 - meter capital warship . Although plagued by rumors of unreliable electronics and sensors , the Bulwark Mark III nevertheless boasted an extensive arsenal , shielding , and carrying capacity . Armed with 1 , 320 turbolasers — 600 fore , 120 aft , and 300 each port and starboard — and 580 ion cannons — 200 fore , eighty aft , and 150 each port and starboard — and outfitted with a support complement of up to ten starfighter squadrons and four troop regiments , the Bulwark was a veritable mobile fortress . Adding to its versatility , the immense battlecruiser was capable of making planetary landfall and disembarking ground forces . The Bulwark was equipped with a hyperdrive system in addition to a basic sublight drive . Role . The Bulwark Mark III ' s powerful armaments and considerable defensive capabilities made it ideal for large - scale military operations . The battlecruiser could absorb and administer damage equal to that of " Imperial " - class Star Destroyers . History . Age of Rebellion . TransGalMeg Industries developed the Bulwark Mark III based on the old designs of the Bulwark Mark I , a behemoth warship produced by the Techno Union and later used by the Confederacy of Independent Systems against the Galactic Republic during the Clone Wars . The Bulwark Mark III directly succeeded the Bulwark Mark II , another Clone Wars – era Confederate battleship . During the subsequent Galactic Civil War , the Bulwark Mark III proved to be one of the most armored , durable , and battle - proof starships employed by the Rebel Alliance Fleet . Additionally , the Sullustan Home Guard , an antipiracy armada established by the SoroSuub Corporation to defend the planet Sullust , also utilized the Bulwark Mark III during this period . Shortly before the Battle of Hoth , the SoroSuub orbital shipyards constructed the Bulwark battlecruiser " Arrow of Sullust " . However , SoroSuub — formally neutral during the Galactic Civil War but secretly sympathetic to the Rebel Alliance in its struggle against the Galactic Empire — could not openly deliver the ship to the Rebellion . The task of stealing the Bulwark thus fell to a group of Rebels , who , with only a skeleton crew , held off Imperial forces long enough to cruise to a safe distance and escape to hyperspace with the " Arrow of Sullust " . Yuuzhan Vong War . TransGalMeg later constructed Bulwark Mark IIIs for the burgeoning New Republic , the Rebel Alliance ' s successor state , early in its existence . In 25 ABY , amidst the Yuuzhan Vong War , the New Republic dispatched at least four Bulwarks to assist in the evacuation of the besieged planet Rychel , whose civilians had fallen under attack by the Yuuzhan Vong . The Bulwarks delivered a joint force of Republic troops and Jedi led by Masters Luke Skywalker and Lar Le ' Ung to Rychel ' s surface to combat the Vong and evacuate as many civilians as possible aboard the battlecruisers . Once filled with Rychel evacuees , the Bulwarks departed the planet with the surviving Jedi and Republic forces , although many civilians were left behind at the mercy of the Yuuzhan Vong , as the New Republic did not have the resources to evacuate everyone . Later in 25 ABY , at least two Bulwarks participated in the joint New Republic – Imperial blockade of the planet Shramar , an effort to prevent the Yuuzhan Vong fleet from recovering its captured slaveship , the " Heart of Artorias " , which the Republic and Imperials were using on the surface to evacuate refugees from the planet . The blockade , however , eventually became part of a larger plan masterminded by Queen Nina Galfridian of the planet Artorias to destroy the Yuuzhan Vong ' s vital supply fields on Shramar . As the Vong attack on Shramar began , Galfridian ordered the joint Republic – Imperial fleet to withdraw into hyperspace and wait , a diversionary move . Convinced the planetary defenders had retreated in defeat , the Vong moved in to attack the " Heart of Artorias " . At that moment Galfridian ordered her ships to return to Shramar . The Bulwarks and the rest of the fleet arrived on the other side of the planet from the Vong force and unleashed a devastating orbital bombardment that wiped out the enemy supply fields before once more escaping into hyperspace and later rendezvousing at the edge of Wild Space . Behind the scenes . The Bulwark Mark III first appeared in the 1998 PC game as one of the playable capital ships available to the Rebel Alliance . Referred to in the game as the " Bulwark Battlecruiser , " and by the in - game encyclopedia as the " Bulwark class capital ship , " the Bulwark represents the game ' s most powerful warship in the Alliance arsenal , designed to be a competitive match for the Galactic Empire ' s Super Star Destroyer in gameplay . As the Bulwark ' s entry in the " " notes , " the Bulwark battlecruiser is the most powerful in the game and can stand toe - to - toe with all Imperial ships except the Death Star [ … ] this battlecruiser is almost a fleet in and of itself . It ' s the natural flagship for any major Alliance fleet . " The Bulwark from " Star Wars : Rebellion " later received a nod in the 2005 reference book " The New Essential Chronology " , which refers to a " Bulwark Mark I " vessel utilized by the Techno Union during the Clone Wars . Author Daniel Wallace explained that he intended this vessel to be a " Rebellion " tie - in , as a sort of Clone Wars – era predecessor to the " Rebellion " Bulwark battlecruiser . Wallace further speculated on the " Rebellion " Bulwark ' s exact relation to his Bulwark Mark I : " I ' ll allow that they could be Mark IIIs or IVs , depending on whether anyone ever goes back to create new ship classes . I ' ve always thought that the New Republic got their hands on Bulwarks at some point post - , but that the Rebel Alliance never did . " In 2008 , the " Rebellion " Bulwark was granted an official starship classification with the release of " The Complete Star Wars Encyclopedia " , which identified the vessel as the " " Bulwark " - class battle cruiser , " drawing upon the original in - game encyclopedia entry material from " Star Wars : Rebellion " . The Bulwark again appeared in the 2009 comic " " , written by Tom Taylor , which featured the starship in a prominent New Republic military role during the Yuuzhan Vong War . Taylor again included the Bulwark in New Republic service in the subsequent 2011 comic " " . Author Jason Fry , who has collaborated with Daniel Wallace on several previous " Star Wars " works , included the " Rebellion " Bulwark in his 2012 reference book " The Essential Guide to Warfare " , in which he established the vessel ' s name as the " Bulwark Mark III " and described it as being built by TransGalMeg Industries for the New Republic . Fry intended to canon ize Wallace ' s plans for the evolution of the " Rebellion " Bulwark class , which Wallace had previously discussed but had never had an opportunity to do so . However , given that Wallace ' s evolution is inconsistent with " Star Wars : Rebellion " , " The Complete Star Wars Encyclopedia " , and the 2015 " " roleplaying sourcebook " Strongholds of Resistance " , all of which state that the Rebel Alliance utilized the Bulwark , this article attempts to reconcile all information .
