A small thruster is a building added by the Odyssey DLC that increases a gravship’s world-map range and improves launch ritual quality.
Acquisition[edit]
Small thrusters can be constructed once the Basic Gravtech research project has been completed. Each requires 180 Steel, 4 Components, 10,000 ticks (2.78 mins) of work modified by the construction speed of the builder, and a construction skill of 4.
Summary[edit]
Small thrusters add 10 tiles max travel distance to a gravship. This means that a gravship using the maximum number of small thrusters (4) can travel 40 tiles using 400 chemfuel.
Summary[edit]
 | This section could use some more or updated images. You can help RimWorld Wiki by uploading images to make this section better. Note: Exclusion zone. |
A gravship can mount up to four small thrusters. They must sit on connected gravship substructure within the build radius of a working grav engine or grav field extender to function.
Each small thruster allows a gravship to travel an additional +10 tiles on the world map, up to a maximum of +40 tiles will all four. Range stacks additively with large thrusters, which provide +16 tiles each up to a maximum of six large thrusters, for a theoretical maximum of 136 tiles with all 10 thrusters. Every tile traveled consumes 
10 chemfuel, so a max-range jump with six large and four small thrusters burns 1360 chemfuel — almost two full large chemfuel tanks. Note that cost can be reduced with fuel optimizers.
Launch ritual quality[edit]
During the launch ritual each small thruster contributes +1% quality, up to a maximum of +4% with four small thrusters. These bonuses stack additively with other quality bonuses, including those from large thrusters. Higher ritual quality shortens the relaunch cooldown and lowers the mishap chance on landing. See the Gravship page for full details.
Exclusion zone[edit]
| This section is a stub. You can help RimWorld Wiki by expanding it. Reason: What blocks the thruster is currently unclear - substructure and coolers and walls do, some other buildings and trees don't. May be impassible buildings and substructure?. |
The small thruster's exclusion zone (1ˣ5 white rectangle) is visible when the thruster is selected, or when placing the thruster blueprint. Any gravship substructure and impassible buildings[Verify] will block the engine and prevent its bonuses from applying to the gravship. The exclusion zones of several thrusters may overlap, so long as the thruster buildings themselves aren't in any of the zones. So long as the exclusion zone is clear, they will function, even if they enclosed by walls or pointing in opposite directions.
