Similar to a Warp Field Drive, an anti-gravity drive can take advantage of warped space to accelerate. This acceleration also pulls the warped space in the opposite direction of the craft. As this warp field collapses, its momentum is transferred to a wave of gravitons. The overall effect of the drive is that energy is spent to accelerate, with an equal and opposite momentum transmitted as waves of gravitons. Antigravity drives are useful on the ground for certain types of hovercraft as they do not require point-placed nozzles to propel, but rather a larger surface area of the gravitic channels that produce the gravitic field warp. Anti-gravity generally appears as simple warps in space and shimmers in the air.
When used to propel ships, anti-gravity confers less speed than both chemical and particle propulsion methods, but have the advantage of producing no heat emissions that can be picked up on radars, making them ideal for stealth crafts when compounded with other features such as stealth technology or aegisalt hulls.
