Unnamed Borg cubes The following is a list of unnamed Borg cube s . By incident . First contact cube . In 2365 Starfleet encountered the first known Borg cube in System J - 25 when Q threw the " Enterprise " into that system . This event constituted the official first contact , although the Borg themselves had been encountered two hundred years before by the crew of and also by civilian researchers in the 2350 s . The Borg cube encountered in 2365 dispatched two drones to the , which examined the ship ' s engineering spaces . The cube then attacked the " Enterprise " , slicing into the saucer section and using a tractor beam to extract components from three decks . Captain Picard had an away team , consisting of Riker , Data , and Worf , beamed aboard the Borg vessel in order to learn more about the Borg . The away team learned a great deal , but then the " Enterprise " had to retrieve the team after finding out that the Borg were telepathically using their collective hive mind to repair their damaged vessel . The " Enterprise " left at warp speed pursued by the Borg cube . The " Enterprise " increased to maximum warp , but still had no success in escaping . Riker ordered them to arm photon torpedoes and Picard gave the order to fire , but the torpedoes had no effect . The Borg ship , after getting within firing range , fired a shield - draining missile twice and the " Enterprise " , with very low shields , fired torpedoes again , with the same result . After determining their weapons were useless , Picard pleaded with Q to send the " Enterprise " back into Federation space , which he did . It is unknown where the Borg cube went after Q helped the " Enterprise " escape . ( ) Flashback cube . This Borg cube appeared to Tuvok in a flashback he experienced during a telepathic communication with a member of Species 8472 , in 2374 . ( ) Klingon space cube . A squadron of the Klingon Defense Force battled a Borg cube of the same type that engaged Starfleet in the Battle of Wolf 359 and suffered substantial losses . ( ) Sector 001 cube . In 2373 , another Borg cube attacked Earth much in the same manner as the previous cube from Wolf 359 . The Battle of Sector 001 ended when this Borg cube was destroyed by a Starfleet armada using tactical knowledge of Captain Picard from his time as Locutus . The Borg Queen was on board this cube , and attempted to escape back in time using a Borg sphere . ( ) Nekrit Expanse cube . In 2368 , this Borg cube was disabled by an electrokinetic storm within a nebula r region of the Delta Quadrant , the Nekrit Expanse . With the majority of the Borg aboard the cube killed , 80 , 000 surviving drones ( freed from the Collective ) fled to a nearby M - class planet . The derelict cube was later discovered by the in 2373 and subsequently boarded by its crew . It was later visited by Commander Chakotay who successfully reactivated the ship ' s neuroelectric generator , rejoining the surviving Borg into a new collective called the Borg Cooperative . The reactivation of the generator also reactivated the cube and its dormant drones , however the Cooperative ordered the cube to self - destruct before all its systems were fully operational . The cube ' s complement of drones consisted of many Alpha and Beta Quadrant species including Human s , Romulan s , Cardassian s , Klingon s , Farn , and Parein . It was the first Borg vessel encountered by the " Voyager " crew . ( ) Two Borg cubes . In 2373 , these two Borg cubes , which confronted Species 8472 , were destroyed . ( ) Fifteen Borg cubes . In 2373 , fifteen Borg cubes passed the USS " Voyager " in pursuit of Species 8472 . One of these cubes stopped momentarily to scan " Voyager " with a polaron beam . All fifteen vessels were later destroyed by a Species 8472 bio - ship . ( ) Seven of Nine ' s cube . This Borg cube , containing Seven of Nine , assisted " Voyager " in developing the bio - molecular warhead against Species 8472 in 2374 . When " Voyager " approached the vessel , it was locked in a tractor beam and Captain Kathryn Janeway was beamed aboard to negotiate the development of the warhead . After Species 8472 destroyed a nearby planet , the cube tractored " Voyager " to warp and to safety to develop the weapon . Janeway and Tuvok , with Seven of Nine as a representative , worked in the vessel on the weapon until the cube was attacked by a Species 8472 bio - ship . The Borg knew that they could not allow " Voyager " to be destroyed ; and so the cube rammed the bio - ship , destroying both . Portions of the cube were beamed into one of " Voyager " s cargo bay s along with Tuvok , Janeway , Seven of Nine , and a number of Borg . ( ) Two Borg cubes accompanying Seven of Nine ' s cube . As captain Janeway sought to contact the Borg in order to make her proposition , she found that besides Seven of Nine ' s cube , two other cubes were in orbit around the Borg planet " Voyager " arrived at . These two cubes were destroyed by the shock wave of the exploding planet , detonated by Species 8472 , while trying to protect Seven of Nine ' s cube from destruction , in which they succeeded to their own detriment . ( ) Borg cubes in fleet . In 2374 , a Borg fleet consisting of 312 ships , a number of which were cubes , were destroyed by Species 8472 in Matrix 010 , Grid 19 . ( ) Species 116 homeworld cubes . In 2374 , a member of Species 116 , Arturis , who blamed Captain Kathryn Janeway for the assimilation of his homeworld , tried to lure the crew of the into a trap . He disguised his ship as a Starfleet vessel , so he could get the crew of " Voyager " on board . However , his plan was discovered and he only managed to capture Captain Janeway and Seven of Nine before he activated the quantum slipstream drive and set a course for his former homeworld , inside Borg space . " Voyager " pursued them and managed to rescue Janeway and Seven . As the vessel emerged from slipstream , it was quickly surrounded by at least four cubes . Arturis and his ship were presumably assimilated . ( ) Species 10026 homeworld cubes . When Seven of Nine briefly returned to the Borg Collective in 2375 , a fleet consisting of the Borg Queen ' s ship and two cubes left the unicomplex to assimilate Species 10026 . Upon arrival they were attacked by 39 vessels armed with pulse weapons , which could penetrate their shields . With the unwilling help of Seven of Nine , the Borg were able to adapt and assimilated almost the entire species . ( ) Cube reduced to debris . In 2377 , " Voyager " found a debris field , the remains of a damaged Borg cube near the Yontasa Expanse . ( )
