A '''borer''' (also referred to as a '''drive core''')<ref name="wf">''[[Halo: Warfleet]]'', p. 10-11</ref> is a type of [[slipspace drive]] created and used by the [[Covenant]] and its [[Covenant remnants|remnants]]. It is a spacecraft propulsion system capable of making transitions to and from [[slipstream space]] and by extension allowing faster-than-light interstellar travel.

==Description==
Being more technologically advanced than humanity, the [[Covenant]] have numerous advantages in slipspace propulsion systems. Whilst the human Shaw-Fujikawa engine is said to “punch” a hole between realms using brute force, Covenant engines instead take a small rupture and delicately enlarge it with surgical precision. This allows the latter to execute far more accurate slips.<ref>'''[[Halo: First Strike]]''', ''page 86''</ref> Covenant slipspace drives are often referred to as "jump drives".<ref>'''Halo: Contact Harvest''', ''page 136''</ref> In addition to their more powerful [[Repulsor engine|thruster engines]], it has been theorized by the UNSC that Covenant drives generate several "microjumps" within a single slipspace transition to measure the dilation involved in a jump, allowing them to reach their destinations faster.<ref>'''Halo: First Strike (2010)''', ''[[Tug o' War]]''</ref>

Covenant drives are generally more flexible and powerful than those of humans, due to their extensive use of [[Forerunner]] knowledge, technology and techniques. They can only be built with assistance from [[Huragok]] savant-technicians and [[San'Shyuum]] designing surrounding systems including power converters and translation interfaces.{{Ref/Reuse|wf}} Their drives They have thrice been seen to execute in-atmosphere slipspace transitions<ref>'''[[Halo: First Strike]]'''</ref><ref>'''[[Halo 2]]''', level ''[[Delta Halo]]''</ref> (although the first time the drive in question was controlled by [[Cortana|a human AI]]). In addition, Covenant drives can execute successful slips even if underpowered.

Covenant slipspace drives can also be refitted to human ships, as seen during [[Operation: FIRST STRIKE]], where the UNSC fitted ''[[Ascendant Justice]]''{{'}}s slipspace drive to the {{UNSCShip|Gettysburg}} to escape ''[[Unyielding Hierophant]]'' and reach [[Earth]] faster.
