Gravitational Mass Displacement Drive

A Gravitational Mass Displacement Drive is a type of N-Space drive used for traveling at speeds lower than the speed of light. The drive works by projecting a gravitational field out in front of the ship, which it then "falls" towards. In most instances the field is projected only off of the bow and attitude control thrusters are required to change the ships angle.

Use

This type of drive is most commonly found on large ships, such as the largest class of capitol ships, as well as Mercury Ships. Some of the largest-scale civilian transport ships also employ the technology, as it is cheap to build and easy to maintain.

Limitations

Under normal operations, Gravitational Mass Displacement Drives have a top speed of around forty PSL, with a very poor Acceleration Curve
