Matalok Mataloks were large Yuuzhan Vong bioships commonly found in the Yuuzhan Vong warfleet . The New Republic referred to them as ' cruiser analogs ' with certain classes . Mataloks were a specific class of cruiser analogs . Characteristics . They were approximately 1 , 200 meters long and had an armament of 40 yaret - kor . They possessed a Yuuzhan Vong wing of 36 Coralskippers . They were used to command the Yuuzhan Vong attack forces . Several different varieties of vessels were grouped together in the " cruiser analog " from " light cruiser analogs " , " assault cruiser analogs " and " heavy cruiser analogs " . Specific Yuuzhan Vong types included the 740m Suuv Ban D ' Krid . The much larger Kor Chokk " grand cruiser " , comparable in size and firepower to a Super Star Destroyer , may also have been grouped into the cruiser analog category . The Vua ' spar and probably the Miid ro ' ik , however , were designated as destroyer analog s . Together , cruiser and destroyer analogs comprised the main fighting force of the largest Yuuzhan Vong fleets . In spite of their relatively large size , many cruiser analogs were also capable of operating deep inside a planetary atmosphere , in direct support of ground troops . It is likely that the " cruiser analog " designation correspond broadly to the standard cruiser designation used by the Galactic Empire and New Republic : combat warships more than 400 meters long that were not Star Destroyers . This excluded most ships above ~ 850 - 900 meters , but some larger ships , like 1 . 2km Mon Calamari Star Cruiser s and the 2km " Invincible " - class Dreadnaught Heavy Cruiser , were typically still referred to as cruisers . History . They resembled the Mon Calamari Star Cruiser s from a distance and were heavily armed and shielded , but there were instances of mataloks being destroyed by proton torpedo shots that would have only dented the armor on a Mon Calamari cruiser . For instance , one Jedi shadow bomb launched from Jaina Solo ' s X - wing destroyed a matalok in the Second Battle of Borleias ( by blowing a large crater , ensuring that the matalok was dying ) . Rogue Squadron X - wings launched a proton torpedo barrage at another matalok to cover a refugee ship later in the same battle . Three of the torpedoes hit , cracking the matalok in half . At least four mataloks fought at the Battle of Duro , and at the Battle of Yag ' Dhul , two mataloks pursued Corran Horn , Anakin Solo and Tahiri Veila as they escaped the system . It is not clear , however , what part of the overall fleet strength in these battles they represented . Later , mataloks together formed the backbone of the fleet in the Battle of the Black Bantha . The combined total of ships of these types was around one hundred , probably 10 % of the complete fleet strength , and they formed a central core of heavily - armed warships , guarding the fleet ' s supply ships , and supported by outer screens of lighter frigate analogs and corvette analogs . It is likely that mataloks from this fleet also played an important role in the Battle of Coruscant . Mataloks could also play a central role in high - level formations , as Wyrpuuk Cha used a Matalok as the command ship of his fleet in the Second Battle of Borleias . However , this is the only certain example of a matalok being used in a command ship role , unless we count this designation as including the " grand cruiser " type to which " Legacy of Torment " and possibly " Yammka ' s Mount " belonged : all other evidence indicates the use of destroyer analog s and worldships . As the Yuuzhan Vong moved to consolidate their conquests after Coruscant ' s capture , mataloks were more often found deployed in pairs for probing missions , often as strike elements of larger fleets , though sometimes as detached taskforces . Later in the Battle of Borleias , two mataloks made a strike against the New Republic positions on the surface , provoking a counterattack by Twin Suns Squadron and Rogue Squadron , in which one was driven off , and one destroyed . in the closing stages of the battle , two mataloks were destroyed by the " Errant Venture " . Elsewhere , a pair of mataloks dropped low into the skies of Coruscant to investigate the disturbance caused by Lord Nyax , and a pair of cruisers were also the core capital ship force of Commander Ekh ' m Val ' s squadron , which located and attacked Zonama Sekot . A number of mataloks also fought in the Battle of Borosk , and at least one was present at the Battle of Esfandia . In the closing stages of the war , mataloks played a role in the major fleet actions comparable to that which they had performed at the Black Bantha and Coruscant . In the Defense of Mon Calamari they were again grouped with destroyer analogs , plus yammosk carriers and fleet tenders , in the center of the fleet formation , with picket ships and coralskippers deployed in screening formations that resembled the arms of a yammosk or indeed a spiral galaxy . This large formation was capable of segmenting into smaller battlegroups , and this tactic was repeated during the Battle of Yuuzhan ' tar , where mataloks played a prominent role in the groups sent against the Fourth Fleet and Zonama Sekot .
