Maneuver drives are the slower-than-light engines of a spacecraft. No spacecraft can survive in space without a working and fueled maneuver drive.
Depending on the quality of the fuel used, the maneuver drive will fluctuate. These fluctuations can be mitigated by a skilled engineer manning the engineer station. High fluctuations can cause any helmsman to have a significantly higher chance of crashing.
Since space stations rely on the maneuver drive to keep orbit, it will fall from orbit and be destroyed if the maneuver drive goes offline.
Maneuver Drive Types
The type of maneuver drive can be selected in the design.
Maneuver drive type can also be changed using maneuver drive modules after the ship has been constructed.
Gravity Drives are the primary engines of space faring vessels. They are produced using Grav Couplings which require resources found on all moons.
Gravity Drives are the next step up from the Rocket Drive, and allow for more advanced maneuvering in space. They are also cheaper to make.
Rocket drives are only slightly less advanced than gravity drives, their main advantage is that they can be be made without the need for eludium, making it useful for any empire's first ship before they have established their first moon colony.
The main disadvantage of the rocket drives is that they can't negate gravity from gravity wells, and even worse they can't escape the gravity of a supergiant star. On top of that they are also harder and slower to manufacture resource wise.
