Create Propulsion: Simulated
With Create Propulsion: Simulated, assembled Create contraptions gain thrusters that push them through the air and sea, with contraption physics handled by Sable.
What it does
The mod ports Create: Propulsion to NeoForge for 1.21.1 and adds support for Sable contraption physics. Force is applied at a point, so torque and multi-thruster setups on an assembled craft behave as they would on a real vehicle. Copycat Wings add lightweight aerodynamic parts with copycat-style visual customization.
Three thruster types cover different builds: a standard thruster burning fuel, an Ion Thruster powered by FE, and a Creative Thruster with configurable output for testing. Thrusters accept several fuel sources added by other mods. The mod is released under the MIT License and is open source, with public source code, an issue tracker and a wiki. Its first file dates from 2026-04-23 and the latest, 1.1.5, from 2026-07-23.
Create Propulsion: Simulated requires Sable for its physics. Client and server both need the mod, so every player on a server that runs it must install it too.
Key features
Standard thruster
A fuel-burning thruster that pushes an assembled contraption, fueled by any of the supported fuel sources.
Ion Thruster
A thruster that draws FE power instead of fuel, suited to builds wired to an electrical grid.
Creative Thruster
A high-power thruster with configurable output, intended for testing designs and creative builds.
Copycat Wings
Lightweight wing parts that take on the appearance of copycat blocks for aerodynamic builds.
Multi-thruster handling
Several thrusters on one craft apply force at specific points, so torque is calculated per placement.

Use cases
Flying contraptions
Builders assemble airships and flying machines and steer them with several thrusters placed around the hull.
Sea vessels
Thrusters move boats and ships assembled from Create parts across water.
Who it’s for: Players who already use Create and Sable and want propulsion for their contraptions. Server owners running those mods need the same set installed on both sides.
