Paragravitic drive

The paragravitic drive was a type of propulsion technology used for sub-light-speeds. It could accelerate a starship from orbit to light-speed.

Orions surpassed the impulse engine to develop the paragravitic drive during the New Days, at the height of their civilization (56 BCE to 1003 BCE, or reference stardates −20/56 to −10/03). However, they lost the knowledge of it during the Reverse that decimated their civilization, as records and ships were destroyed.

The technology of the paragravitic drive remained unknown to Federation science in the late 23rd century.
