A '''maneuver drive''' is a propulsion system used on starships, for the purposes of sub-light travel. For faster-than-light travel, starships must transit the medium of [[slipstream space]] via usage of a [[slipspace drive]]; maneuver drives do not allow for slipspace transit, nor do slipspace drives allow for realspace maneuvering. All forms of maneuver drives convert energy into thrust, augmented with a reaction mass, however different types of maneuver drives will perform this using different mechanisms.{{Ref/Book|HWF|Page=14}}

==Types of maneuver drive==
===Human===
{{Main|Fusion drive}}
Starships employed by [[human]]ity typically employ [[Fusion reactor|fusion]] rockets, capable of generating both the ship's electrical power and thrust. These systems eject hot [[plasma]] from their exhausts which can be extremely hazardous to anything caught in its wake, but is made up for by the mobility offered by the system (especially when used in conjunction with inertial compensation to minimise the effects of rapid acceleration and maneuvering). Human ships generally employ a mix of high-thrust and high-efficiency to balance the consumption of reaction mass in different stages of a journey. For more delicate and slower movements, [[human starship]]s will use chemical rockets.{{Ref/Book|Enc22|Page=114}} Such chemical rockets may also be built into the hull as one-use [[emergency thruster]]s.

===Covenant===
The [[Covenant]] use reactionless drives for their [[Covenant starship|starships]], which are able to move their respective vessels without generating an exhaust of hot gases. The most impressive of their maneuvring systems are [[repulsor engine]]s, which used stacked tidal [[Anti-gravity technology|antigravity]] generators to to "push" or "pull" the ship in a given vector. These systems are able to function in atmosphere and in space and maintain a thrust-to-mass ratio outmatched only by the technologies of the Forerunners.{{Ref/Book|Enc22|Page=223}}

Covenant heavy [[Space fighter|strikecraft]] and [[Dropship|shuttlecraft]], and lighter Covenant spacecraft, utilise [[impulse drive]]s; a form of drive powered by a small-scale [[pinch fusion reactor]] and capable of both atmospheric and space flight.{{Ref/Book|Enc22|Page=218}}

===Forerunner===

{{Main|Torsion plate}}
The [[Forerunner starship|spacecraft]] of the [[Forerunner]]s utilise a form of inertialess drive technology known as [[torsion plate]]s, which convert harvested energy into thrust via way of emitting [[torsion field]]s.{{Ref/Book|Enc22|Page=338}} They are also known to have used a form of propulsion system known as a [[reaction drive]] - though what a reaction drive entails is unclear.

The impulse drives of the Covenant were originally descended from Forerunner equivalents.
