Geshrinari Shipyards manufactures Plasma Drives for their designs that need high performance sub-light engines. These engines are similar in function to the Turbo Aether Plasma Drive and are powered by the primary power system. However because they are not Aether powered, they produce a lower temperature plasma that is not hazardous, and have a lower performance rating. These engines can be used in any Geshrinari Shipyards design that features aether plasma drives as replacement.
The outer ring on nozzles on the engine are vernier thrusters. It is a smaller thrust motor than main attitude control motors and is used for fine adjustments to the attitude or velocity of a spacecraft.
Geshrinari Shipyards can produce them even in a modular version to fit in an Geshrinari Modular Aether Plasma Drive mounting.
