Sith fleet ( New Sith Wars ) The Sith fleet was the spacegoing arm of the Sith military which fought for the Brotherhood of Darkness in the closing stages of the New Sith Wars . Ships . Typical capital ships were Sith Dreadnaught s and other cruisers , but Sith Destroyer s like the flagship " Nightfall " were probably even more powerful , and smaller corsair battleship s also served as attack ships . Alongside the larger ships , the Sith fleet made use of starfighters like the Buzzard and Sith interceptor , troop transports like the Interloper , and other small ships such as the T - class long - range personal cruiser . From their names , it appears that most of these types were unique to the Sith fleet , indicating that they were constructed in shipyards under Sith control , probably in the Outer Rim , where the Brotherhood of Darkness commanded most of their support . Organization and tactics . The fleet was normally commanded by Lord Kaan in person from the " Nightfall " , but the ranking naval officer was Admiral Adrianna Nyras . Naval personnel appear to have been non - Force - sensitive , but , especially when driven by Kaan ' s battle meditation , the Sith fleet was capable of challenging the Republic Navy in combat . Operations were based around the control of planets . Attacks involved overwhelming the defending Republic forces in orbit and deploying Sith ground troops for surface combat , and defensive tactics were centered on preventing Republic forces from fighting their way through to place their own troops on Sith - controlled worlds . Operational history . It is not known what sort of naval assets Kaan acquired from the feuding warlords who he united into the Brotherhood of Darkness , or what sort of fleet was available to the Brotherhood in the first years of their campaign — for instance , at the Battle of Korriban in 1006 BBY . By 1003 BBY , however , the Sith fleet was capable of leading the conquest of Kashyyyk to establish a foothold in the Mid Rim , and in 1002 BBY , they won the First and Second Battles of Ruusan , eliminating the Republic staging base being used to strike back at Kashyyyk . It was probably at around this time that the Sith fleet was involved in battles at Bespin and Sullust on the Outer Rim , and then at Taanab , near the Hapes Star Cluster . Kaan was surprised not to be opposed by a fleet led by Lord Hoth , the Jedi Master and General who was regarded as the Republic ' s greatest defender : but the Jedi seemed abruptly absent from the war . The clash at Taanab , located on the Perlemian Trade Route in the Inner Rim , may have marked the start of the fleet ' s push into the Core . Undeterred by the seeming disappearance of the Jedi , the fleet thrust forward with a campaign in Bormea sector , including the conquest of Corulag , Chandrila and Brentaal IV , and the wresting of both the Perlemian hyperlane and the Hydian Way from Republic control . But at this point , Lord Hoth revealed his hand : he had gathered the Jedi in a military force named the Army of Light , and they liberated Ruusan , defeating the defending naval squadron using a massive starfighter attack , and forcing Kaan to return to face them . By 1000 BBY , and the closing stages of the Ruusan campaign , most of the fleet had been withdrawn to guard Ruusan itself , entrenched in orbit and outnumbering the Jedi fleet in the outer system , in order to prevent them from providing reinforcements to the Army of Light . During the Seventh Battle of Ruusan , as part of his plot to destroy Kaan and the Brotherhood , Darth Bane ordered Admiral Nyras to break out from her defensive position and attack the Jedi fleet , allowing Lord Valenthyne Farfalla ' s gunships to fight their way through to the surface with reinforcements . The Sith were defeated during that battle , with Kaan and his Brotherhood wiped out .
