Conqueror ( superlaser ) The Conqueror was an " Imperial " - class Star Destroyer armed with a superlaser that was in operation during the Galactic Civil War . Conceived as a replacement for the Galactic Empire ' s planet - destroying superweapon , the Death Star , lost at the Battle of Yavin , the " Conqueror " was intended to slow the momentum of the rapidly growing Rebel Alliance . The superlaser component of the Star Destroyer was constructed at an Imperial research facility on Naboo under the supervision of the Imperial storm commando s . It was projected that the superlaser on the " Conqueror " , when properly installed , would give the Star Destroyer the ability to break apart a small moon , or crack a continent in half . By 1 ABY , the weapon was equipped on the " Conqueror " , and the Star Destroyer was located in the Mustafar system , where it was commanded by Admiral Victor Strang . There , the Star Destroyer ' s superlaser was successfully tested on a small planetoid . Shortly thereafter , the Alliance ' s Renegade Squadron came across information on the " Conqueror " during several raids on Imperial facilities located on Naboo , and they set out to destroy the vessel . After hijacking a shuttle on Mustafar that was bound for the " Conqueror " , the Renegades were able to infiltrate the Star Destroyer and plant timed explosives on the ship ' s reactor core , which would cause the vessel to explode once detonated . Strang and the Imperial forces on the ship were unable to stop the Rebels , and after a confrontation with Emperor Palpatine ' s enforcer , Darth Vader , who had recently arrived on the ship , the Renegades were able to escape the " Conqueror " shortly before it was destroyed . Description . The " Conqueror " was a 1 , 600 meter - long " Imperial " - class Star Destroyer . The starship had a spacious hangar bay that was large enough to hold several " Lambda " - class T - 4a shuttles , a TIE Advanced x1 starfighter , and an Incom X4 Gunship . In the aft section of the Star Destroyer was the ship ' s reactor core . The vessel had a number of security measures installed in the case of an emergency , including blast doors , an alarm system , and red emergency lights placed along ship ' s corridors . The " Conqueror " most distinguishing feature was a superlaser , similar to the one used on the first Death Star battlestation , which was built into the vessel ' s bow and took up much of the surrounding area , bisecting the forward section of the Star Destroyer . The superlaser consisted of several beam generators arrayed around a concave circular dish located on the prow of the ship . When the weapon was fired , beams emanated from the generators and converged into a single green laser capable of destroying a small moon , and at the very least crack a continent in half and melting cities , although it was purported to have the ability to demolish entire planets as well . History . The " Conqueror " was conceived as a replacement for the Galactic Empire ' s first Death Star , a superweapon capable of annihilating planets that was destroyed by the Rebel Alliance at the Battle of Yavin in 0 BBY . However , the concept itself and to a lesser extent the retrofitting of the " Conqueror " itself was experimented on as early as 0 BBY , and was included in the official field guide for officers of the Imperial Military , the " Imperial Handbook : A Commander ' s Guide " . During this time , the project ran into issues with miniaturization and power output , as well as plans to create more Star Destroyers equipped with superlasers . With the Rebels quickly gaining momentum in the Galactic Civil War , Emperor Palpatine was intent on swiftly halting the uprising through a crippling counterattack intended to demoralize the Alliance . The project to develop the " Conqueror " superlaser was spearheaded by the Empire ' s elite storm commando s , led by Admiral Victor Strang , who intended to use the weapon to destroy worlds affiliated with the Alliance . The superlaser was developed at an Imperial research facility on Naboo , which was guarded by the Imperial - allied Sith Acolyte Namman Cha . Eventually , the weapon was fitted onto the " Conqueror " , and by 1 ABY the Star Destroyer had been put under Strang ' s command and stationed in the Mustafar system . Imperial Intelligence became involved with the project , and Intelligence Director Ysanne Isard herself began overseeing the operation , working in conjunction with the Blackguard , a dark side cult based on Mustafar . At some point , the " Conqueror " performed a successful test of its superlaser , obliterating a small , uninhabited planetoid in the system . This test was documented and sent to the research facility on Naboo . Soon after , the Alliance learned of the " Conqueror " existence after a raid on an Imperial weapons depot on Naboo , which was carried out by the Alliance ' s elite Renegade Squadron , led by Commander Col Serra . The team turned up datafiles containing information on the Star Destroyer . The Renegades discovered the research facility where the superlaser was developed and infiltrated it , defeating Namman Cha and gaining access to the computer consoles located there . Once they came across the recording of the " Conqueror " weapons test and discovered the ship ' s location , they headed to Mustafar and hijacked one of the Imperial supply shuttles that flew between the " Conqueror " and the surface of the planet each day . The team intended to use it to board the superweapon and destroy the vessel . The Renegades were able to provide the correct identification codes to dock with the " Conqueror " , and upon arrival in the ship ' s hangar , they opened fire on the surrounding stormtroopers . This alerted the Imperials to their presence and set off the ship ' s alarm system . They made their way to the " Conqueror " critical reactor core , which the Renegades hoped to destroy using thermal detonators , thereby causing the ship to explode . On the way there , the team was encountered by Strang and his storm commandos . Serra and the Renegades defeated them and eventually reached the reactor core , placing timed detonation charges around it . Simultaneously , the Emperor ' s enforcer , Darth Vader , arrived aboard the vessel to see to the superweapon ' s safe delivery to the Emperor . After ten minutes of fighting through the ship ' s corridors , the Renegades reached the hangar , intending to leave on the very shuttle they arrived in . There , they were confronted by Vader and a group of storm commandos . Serra and the Renegades were able to gain the upper hand in the subsequent firefight and escaped the " Conqueror " as the detonators exploded and destroyed the ship . Despite their success , two Imperial vessels , including Vader ' s , were able to escape the destruction as well . Crix Madine later confirmed its destruction in the " Imperial Handbook " after a copy was supplied to the Rebel Alliance , in the aftermath of the Battle of Endor . Commanders and crew . At the time that it was stationed in the Mustafar system , the " Conqueror " was captained by Admiral Victor Strang , a former storm commando leader . Strang kept a personal guard of storm commandos with him on the Star Destroyer , which he brought along when he encountered Renegade Squadron aboard the vessel . He was protective of his ship , disliking the idea of it being stolen or destroyed , and personally confronted the Renegades when they attempted to achieve the latter . Just before the " Conqueror " destruction , an Incom X4 Gunship , which one of the Renegades thought may have been carrying Strang , escaped the doomed Star Destroyer . Along with Strang ' s storm commandos , the " Conqueror " carried a number of stormtroopers and Imperial Navy trooper s . Stormtroopers were present in the ship ' s hangar when Renegade Squadron first arrived aboard the vessel , and Navy troopers attempted to halt the advance of Serra and his Renegades when they were making their way to the ship ' s reactor core . Stormtroopers and Navy troopers were also encountered by the Renegades at several critical junctions across the ship on the way back to the " Conqueror " hangar . Additionally , several groups of workers were spread throughout the large hangar bay at the time . Behind the scenes . The " Conqueror " was created for the 2010 " Threat of the Conqueror " expansion set of the " Star Wars Galaxies Trading Card Game " developed by Sony Online Entertainment . The Star Destroyer was featured in the Light Side scenario campaign for the set , in which the player character joins Renegade Squadron in uncovering information on the ship and destroying it . It also received its own card in the set , an item card usable only by Imperial players , and was referenced on several others . The " Conqueror " was illustrated by artist Derek Herring . Discrepancies . Promotional material on Sony ' s website concerning " Threat of the Conqueror " indicates that the Rebel Alliance assigns Renegade Squadron to specifically target and destroy the " Conqueror " . However , the Light Side scenario campaign depicts the Renegades attacking an Imperial weapons depot and coincidentally coming across information on the " Conqueror " themselves , which they then set out to destroy . A description of the campaign within the game also indicates the involvement of the Jedi in the mission to search for the " Conqueror " , although they are never mentioned in the campaign . Additionally , promotional material indicates the " Conqueror " involvement in the Dark Side scenario campaign as a weapon used by the storm commandos , but the " Conqueror " neither appears nor is mentioned in the narrative of that campaign . The destructive capability of the " Conqueror " superlaser is only ever witnessed during the test on the rogue planetoid in the Light Side scenario campaign . However , promotional material on StarWars . com indicates that the Star Destroyer ' s superlaser has the ability to destroy whole planets , as does the in - game synopsis for the overall campaign and the quote provided for Victor Strang on his card . The only images of the " Conqueror " , featured on the Star Destroyer ' s card and on Sony ' s website , depict the ship hovering over a city with its superlaser being fired while Strang and his troops engage in combat on the ground . However , this scene is completely absent from the Light Side scenario campaign . In the campaign , the " Conqueror " is only ever seen stationed in the Mustafar system , where its weapon is tested , and is destroyed by Renegade Squadron shortly afterward .
