The Icon Block Large Thruster Large Thruster provides a significant amount of force in a single direction. Placement of any thruster will provide thrust in a single direction at the center of mass regardless of placement. It should be noted that now that there are more thruster types; all data on this page refers to the Large Ion Thruster. This is due to the fact that Keen Software House has renamed the block.

Large Thrusters can be set to continuously provide force with the "Thrust Override" function. For Large Ship Thrusters, this is from 36 KN to 3.6 MN. For Small Ship Thrust this is 1.44 KN to 144 KN.

See Thruster mechanics for more details about this block's effects.
Other Thrusters include:


The power consumed by a Large Thruster depends on whether or not it is active or used for inertial dampening. The dampening value only applies if the thruster is activated automatically to slow the ship, not when responding to play commands, even if dampeners are turned on at the time. In this state, power consumption is 50% greater than firing thrusters manually.

Firing 2.4 MW 33.6 MW
Dampening 3.6 MW 50.4 MW


A Large Thruster takes up a 2x3x4 block space on both large and small ships. It attaches to other blocks on its cube-shaped section, but does not attach on the thruster cone. The thruster flame takes up to 7 blocks after the thruster cone (so if you are building thrusters inside of your ships, always leave at least 3 empty blocks for the flames).

As of Update 01.022, thrusters will deal damage to blocks and players in the Survival game mode.

As of Update 1.040, thrusters can now be toggled, meaning used without a cockpit and set in a state of constant firing. This allows for both non-cockpit navigation, as well as un-manned craft such as missles.
