The L5-P3604 graviton drive was developed for NovaCorp's No-L5-1a - Prosperity-Class Starship, and it became available in YE 36.

The drive is similar to the Geshrinari Graviton Engine. It is a reliable and safe propulsion for use around people and withinin atmospheres. As such, it is safe to use during landing and launching from planets and other locations with atmospheres. The drive produces a constant thrust, but suffers from a low acceleration rate. Their thrust efficiency is dependent upon the presence of a body with sufficient gravity. In deep space, outside of the influence of a star system's gravitic forces, the graviton drive is ineffective.
