Best Grav Drives

Best Grav Drive Overall

The J-52 Gamma Grav Drive is the best grav drive we've encountered in the game so far. Despite its high cost and skill requirement, it provides the highest grav jump thrust of 50 which will allow you to travel to systems with long distances without having to make stops in between.

While the Apollo GV300 Grav Drive provides the same grav jump thrust, the J-52 Gamma Grav Drive sports a higher grav drive health for only a slightly higher price.

The grav drive can be purchased from most ship technicians once you reach level 54.

The Helios 300 Grav Drive is the best grav drive to get early in the game. It provides the highest grav jump thrust at 23 among Class A grav drives without requiring any skills, so you'll be able to purchase and utilize it even if you are not investing any skill points in Piloting or Starship Design.

The grav drive can be purchased from most ship technicians once you reach level 14.

What is Grav Drive Class?

What is the Class Stat?
Determines Ship Part Tier Level Limits Parts That Can Be Added Higher Classes Require Skills

Determines Ship Part Tier Level

Reactors come with a stat called class that indicates the maximum tier of parts you can attach to your ship. Classes can either be A, B, or C, with the latter being the highest tier being accompanied by the best stats.

Limits Parts That Can Be Added

The reactor's class sets the limit for the other ship parts. If your ship has a Class B reactor, you can only attach parts that are either from the same class or lower.

Higher Classes Require Skills

Skill	Description
Piloting	As more people journey into space, the number of those certified to effectively pilot various types of spacecraft has increased dramatically.
Starship Design	As with "car culture" on Earth centuries ago, there are those who pride themselves on the ability to modify their own spaceships.

To be able to purchase and install parts from higher classes on your ship, you'll need to level up the skills listed above. At higher ranks, The Piloting skill will allow you to pilot Class B and C ships, while the Starship Design skill will allow you to install higher class parts to your ship.

Grav Drive Ship Building Error Explained

Need More Grav Jump Thrust

Ship is too heavy to grav jump. Reduce mass or increase grav jump thrust.

Your ship has too much mass for the Grav Drive to handle. To fix this error, either upgrade to a Grav Drive with higher Grav Jump Thrust or reduce your ship's mass by removing extra ship parts or changing current parts to something with less mass.
