Maneuver drives are the standard slower-than-light engines of a spacecraft. No spacecraft can survive in space without a working and fuelled 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.
They produce their own internal gravity and can fully cancel out gravity from other celestial bodies. This makes them immune to the effects of strong gravity wells.
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 less advanced than gravity drives, with their main advantage being that they can be be made without the need for eludium. This makes them 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, black hole, or neutron star. On top of all that, they are also harder and slower to manufacture resource-wise.
