Warp coil Warp coils were an integral part of a starship ' s warp drive . Mounted within the warp nacelle s , the coils used the plasma generated by the warp core to create a subspace displacement field that allowed faster - than - light travel . Warp coils were typically composed of cast verterium cortenide surrounding a core of densified tungsten - cobalt - magnesium . ( ) When matter and antimatter on an starship collided together , it created an extreme amount of energy within a warp core which was then transferred to conduit s , leading to the nacelle s outside the ship which contained the warp coils , thus creating a subspace displacement field around a ship , allowing it to travel at warp speed . ( ) Around a kiloton of gallicite , a mineral , was enough to refit the warp coils of an vessel . ( ) A Class 2 shuttle could generate a dielectric field with its warp coils to protect itself from turbulence within a planet ' s atmosphere . ( ) A teraphasic coil was a type of warp coil utilized by the Xyrillian s in the mid - 22nd century . " Enterprise " NX - 01 encountered a Xyrillian starship with damaged teraphasic coils in 2151 . ( ) In 2152 , a group of Mazarite criminals chased " Enterprise " on Mazarite ship s at warp 4 . 9 in order to capture Ambassador V ' Lar before she could testify against them . In order to sustain their warp velocity , the ships released drive plasma to keep their warp coils from overloading . ( ) Later , the automated repair station asked Jonathan Archer what he could compensate it with to repair " Enterprise " after it was severely damaged in an encounter with a Romulan mine . The station then told Archer he could supply it with three warp coils , five deuterium injector s , or two hundred liters of warp plasma . ( ) Later that year , Commander Charles Tucker III asked Ensign Travis Mayweather if he could re - polarize the warp coils in " Enterprise " s starboard nacelle , since he was shorthanded with his engineering staff . ( ) In 2153 , after discovering debris of a Borg sphere destroyed in 2063 by the that crashed in the Arctic Circle , the scientist speculated that a Borg transwarp coil she found might be some kind of warp coil . ( ) " In an alternate timeline , Captain T ' Pol crashed a Xindi - Reptilian warship that was docked with " Enterprise " into another , causing massive damage to " Enterprise " s starboard nacelle . Commander Tucker told her that half the warp coils in the nacelle were fused . Tucker told T ' Pol he would have to rebuild the coil assembly from scratch , which would take him a minimum of six months . " ( ) In 2154 , after awakening from an induced coma for three days , Commander Tucker complained that it would take him days to realign the warp coils on " Enterprise " after Phlox slightly damaged the ship while trying to take it to warp inside a nebula in the Delphic Expanse . ( ) Later on , " Enterprise " s primary warp coil was destroyed in the fierce battle of Azati Prime , making warp speed impossible for the starship . Captain Jonathan Archer , with no other options to restore warp capability to " Enterprise " , stole a primary warp coil from the Illyrian s in order for the ship to intercept the Xindi weapon in time to save Earth . ( ) Shortly afterwards , T ' Pol suggested to Commander Tucker that she could order him to go to sleep , since he had not slept for two days . Tucker told her he couldn ' t , since " Enterprise " was full of holes and the only thing allowing them to travel at warp speed was a stolen warp coil . ( ) Later , while attempting to capture Dr . Arik Soong and his Augment s in Klingon space , Commander Tucker had " Enterprise " s warp coils realigned , so the ship would appear to be a Klingon battle cruiser to Klingon sensors . ( ) In the mirror universe in 2155 , Commander , when seeing the , mentioned that the size of the ship ' s warp coils could allow the ship to travel at speeds faster than warp 7 . ( ) In 2366 , a Romulan vessel exceeded its maximum warp speed by thirty percent in an effort to reach Gomtuu before the . It ended up causing permanent damage to its warp coils . ( ) In 2367 , while in a simulation created by Barash , Admiral Jean - Luc Picard told Captain William T . Riker that peace between the Romulans and the Federation occurred after Riker saved a Romulan battle cruiser that had its warp coils and life support fail on them . ( ) Later that year , the warp coils on the Klingon starship , commanded by Gowron , were damaged after a Klingon Bird - of - Prey opened fire on the " Bortas " in orbit of Qo ' noS , plunging the Klingons into a Civil War . ( ) Wesley Crusher once stated that his first friend was a warp coil . ( ) William T . Riker , in 2368 , considered the warp coil the most important invention of the past two hundred years . Before the coils were invented , " " Human s were confined to a single sector of the galaxy " " . ( ) In 2368 , the " Enterprise " - D ' s starboard warp coil suffered from a minor fluctuation , as reported to Captain Jean - Luc Picard by his chief engineer , Geordi La Forge . ( ) In 2369 , Captain Edward Jellico told Lieutenant Commander Geordi La Forge that he found the efficiency of the " Enterprise " - D ' s warp coils unacceptable shortly after taking command . ( ) The used trionic initiator s in the warp coils , which had the reputation of creating strange side effects , such as warp bubble s and subspace deformations . ( ) In 2372 , a subspace inversion in the Bajoran wormhole damaged the and its warp coils were locked into a feedback loop . ( ) " In an alternate timeline , Lieutenant Lasca asked Harry Kim if he brought the schematics for the ' s warp coil with new plasma flow equations for their meeting with Admiral to show they had solved the dilithium fracture problem with the ship . Kim did not bring it with him , however . " ( ) Later that year , the required polyferranide to help seal its warp coils . " Voyager " was able to obtain a small amount from the Sky Spirits ' homeworld . ( ) Later , Lorrum , a Kazon , asked Crewman Michael Jonas to sabotage " Voyager " s warp coils , so the Kazon - Nistrim would be able to commandeer the ship . ( ) When " Voyager " was severely damaged by proton bursts , Lieutenant Tuvok reported that the warp coils on both of " Voyager " s nacelles were fused and inoperable . ( ) In 2374 , Lieutenant Tom Paris and Neelix bribed an alien in the Delta Quadrant with a spare warp coil from " Voyager " , so he would provide him with information on , who stole many important items from the ship , which the crew were intending to get back . ( ) Later that year , " Voyager " s warp coils were in need of maintenance after the ship narrowly escaped from the Hirogen and a black hole . ( ) In a holographic simulation of " Voyager " s crew created by Seven of Nine , Neelix suggested that re - phasing the warp coils would increase power to the nacelles . ( ) In 2375 , the crew of " Voyager " stole a transwarp coil from a Borg sphere and used it in place of its warp coils to generate a transwarp corridor propelling the ship at much faster speeds than a regular warp coil could . The transwarp coil ended up taking " Voyager " 20 , 000 light year s closer to the Alpha Quadrant before eventually giving out . ( ) In 2377 , USS " Voyager " landed on a planet to make repairs . Among the repairs was the removal and maintenance of several warp coils via shuttle . ( )
