Ion thrusters are the original thrusters of Vanilla Alpha Space Engineers, now renamed as Ion thrusters. These thrusters

use only electricity to provide propulsion to the vessel designed. While Space Engineers version 1.157013 has more options for thrusters in game; Keen Software House has decided to make these thrusters "more-end-game orientated." To do just that they renamed thrusters to Ion thrusters, and required them to be made of

massive amount of thruster components, the most expensive and tediously crafted component in the game. thruster components are required to build Ion thrusters. However, once built, Ion thrusters provide near infinite propulsion as long as there is a source of power on the grid they are attached to.

Compared to Atmospheric thrusters and Hydrogen thrusters, Ion thrusters provide less force but draw more Energy from their power supply. However, unlike Atmospheric thrusters which can only work in an atmosphere, Ion thrusters work in a vacuum (space), and in an atmosphere.

Additionally, Ion thrusters are average in size compared to their brethren and because they do not require a conveyors to operate, can make a ship design more compact; adding to their utility. Furthermore Ion thrusters have more 'mount points' than the other thrusters. What this means is that Ion thrusters have more surface areas where other blocks can bind and connect to the thruster furthering their usefulness; making Ion thrusters a lot easier to build with. Due to this utility, a draw back to Ion thrusters is that they require Cobalt, Platinum, Gold, and Iron to build, making them the most expensive thruster in the game. Ion thrusters provide less thrust in an atmosphere. It should be noted that the Ion thruster is the Jack-of-all-trades

thruster as it does not out-perform its brethren in any one field, but compensates in its versatility. Oddly enough Ion thrusters for small grids have the smallest mass compared to their counterparts. The inverse is true for Large grids. Large grid Ion thrusters are bigger, and heavier in mass than its sister thrusters.

A weaknesses of the Ion thruster is its mass and its power draw. While compared to Atmospheric thrusters the difference of the two thrusters' power draw is not all that much. However, this high power draw is exacerbated by the low power draw and high thrust output of Hydrogen thrusters.

Types of thrusters:

  1. Atmospheric thrusters
  2. Hydrogen thrusters
  3. Ion thrusters (this page)

Google defines ion as




  1. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
