Boosted gravity propulsion drive

The Boosted Gravity Propulsion Drive is the Covenant's form of propulsion used in their ground and air vehicles like the Type-32 Rapid Assault Vehicle.

Introduction
The Gravity Propulsion Drive is an anti-gravity generation device that, when activated creates an electrically charged anti-gravity field that will lift an object off the ground and propel it. Most Covenant ground and air vehicles are propelled by this technology, allowing the vehicle to skim above the ground while it is activated. This drive is visible as a bright, fluorescent area of blue energy emanating from the underside of the vehicle.

Some air vehicles like the Type-26 Ground Support Aircraft uses a modified gravity propulsion system to attain flight, and provide thrust using pods on the vehicles wings and rear section. Vehicles equipped with this drive also have the ability to divert power from other non-critical hardware to increase speed for either short, or infinite amounts of time. The boost feature of the gravity propulsion drive allows a vehicle to increase its maximum speed and cover large areas and can either allow a vehicle to serve as a rapid attack vehicle or to aid in fast bombing runs.

Advantages
The propulsion drive allows a vehicle to hover slightly above the ground and can, dependent on the vehicles design, prevent the vehicle from flipping over. The drive also allows a vehicle to move seamlessly and can rotate 360 degrees with very little difficultly. With a boost drive attached, a vehicle using this device can travel at fast speeds and is able to cover a large area in a short amount of time.

Disadvantages
The gravity propulsion drive is more difficult to control with heavier vehicles, although it can still keep a vehicle well off the ground, the speed and maneuverability of heavy class vehicles is limited. Despite apparent simplicity and grace, vehicles that utilize the gravity propulsion drive requires a skilled driver to handle the vehicle properly, the pilot must also take terrain into account as uneven or broken terrain causes the the vehicle to dip, rise or not allow the vehicle to hover or move effectively in these types of terrain. Although the boost feature can propel vehicles at fast speeds, it does limit maneuverability and renders weapons system inoperable until the vehicle comes out of boost.
