Maneuver drive

From Halopedia, the Halo wiki

UNSC In Amber Clad using its fusion maneuver drives to perform an intercept on the Syfon-pattern assault carrier, Solemn Penance.

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.[1]

Types of maneuver drive[edit]

Human[edit]

Main article: Fusion drive

Starships employed by humanity typically employ 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 starships will use chemical rockets.[2] Such chemical rockets may also be built into the hull as one-use emergency thrusters.

Covenant[edit]

The Covenant use reactionless drives for their 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 engines, which used stacked tidal 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.[3]

Covenant heavy strikecraft and shuttlecraft, and lighter Covenant spacecraft, utilise impulse drives; a form of drive powered by a small-scale pinch fusion reactor and capable of both atmospheric and space flight.[4]

Forerunner[edit]

Forerunner skydocks made use of torsion plates for in-atmosphere maneuvring.
Main article: Torsion plate

The spacecraft of the Forerunners utilise a form of inertialess drive technology known as torsion plates, which convert harvested energy into thrust via way of emitting torsion fields.[5] 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.
