Space Engineers Thrusters Guide: All Types, Stats, How to Use, & More

Posted on by justin
Building a spaceship in Space Engineers requires careful consideration of the vessel’s various components. One notable piece that should be on your ship is the thruster. Otherwise, it’s going to be a floating brick in space. So, here are the details you must know to build and use thrusters in Space Engineers properly and all of the many options to propel your ship to your next adventures.

Space Engineers Thrusters Guide

Space Engineers Thrusters Like its real-life counterpart, Thrusters in Space Engineers are the primary means for a ship’s movement. Similar to house building in Terraria, strategic placement is essential for these components. With proper placement, Thrusters only provide direct linear thrust. However, thrusters don’t apply torque or cause ship rotation.

Using Thrusters

As mentioned earlier, thrusters are vital functional blocks for all ships Space Engineers ships, particularly those requiring flight. A requirement of one thruster block facing the opposite direction of the desired path can generate movement. Note that improper thruster placement can cause tailspinning. Thrusters in Space Engineers also have a maximum speed of 100 meters per second (360 kilometers per hour). Additionally, each thruster type has advantages and shortcomings in various environments.

Thruster Types

Space Engineers has three primary thruster types, which are the following:
Ion Thruster
An electric-based thruster that always consumes a minimum of 0.002kW (2 Watts) regardless of its current operational state. The Ion Thruster has a power consumption that scales linearly with an efficacy that’s inversely dependent on the current atmosphere’s density. With these traits, ion thrusters are often ideal for space exploration.

Hydrogen Thruster
All thrusters under this model require a Conveyor connection to a Hydrogen source (e.g., Hydrogen Tank and Oxygen Generator). The Hydrogen Thruster also only consumes hydrogen as a power source, unlike the Ion Thruster, which requires electricity. This thruster type can be good in space and different atmospheres. However, it can also be the most expensive to maintain out of the three thruster types.

Atmospheric Thruster
A thruster model that depends on the atmosphere’s density. So, it’s a good choice for planetary exploration. The Atmospheric Thrust also has the most powerful thrust among the different thruster types. But other thruster models can beat its prowess during extended use.

Requirements

Survival Mode players in Space Engineers can enable Progression, an optional game mechanic. If you do, you must build a Cockpit or Remote Control to unlock Atmospheric and Ion Thrusters. Also, build a Hydrogen Tank and an O2/H2 Generator to unlock Hydrogen Thrusters.

Thruster Damage and Immunity

A map or server can enable a mechanic called Thruster Damage. If enabled, Thrusters in Space Engineers can deal damage to blocks, particularly those directly behind. However, thruster flames that consume small grids don’t damage blocks with deformation ratios below 25%. The blocks immune to Thruster Damage are the following:
Large Blocks
  • Blast Doors
  • Blast Door Corner
  • Blast Door Corner Inverted
  • Blast Door Edge
  • Control Stations
  • Drill
