Realism Overhaul (KSP-RO)

Description from

Realism Overhaul is a mod that makes Kerbal Space Program behave more like real life. If you’re interested in seeing what it’s like to fly rockets in the real world, this is the mod for you! Realism Overhaul does this by combining and configuring other mods, and mod and stock parts to perform as their real-life equivalents. You can expect things to be a little harder, and rockets to be a bit bigger, but the scenes far more epic, and the accomplishment that much greater.

Some of the most signfiicant changes include:

  • Engines have real sizes and performance values, and use real fuels. Most of them have limited ignitions and suffer from ullage.
  • Pods are as large as their real-life counterparts and weigh what they should.
  • Propellant tanks have correct dry mass ratios.
  • Solar panels don’t produce massive amounts of energy, but they are lighter. Similarly reaction wheels aren’t magically powerful anymore (though they still don’t require momentum dumping).

What KSP-RO installs

Kerbal Space Program Realism Overhaul adds the following folders

Ships (adds realistic ships to the selection)

Currently, it does not overwrite any files, so deleting the GameData\EngineGroupController and GameData\RealismOverhaul you can restore the game to the original state. The added ships do not change the gameplay.

KSP-RO Installation

  • Download the the latest build from
  • Unzip the file into a directory
  • Copy the contents into the Kerbal Space Program main directory, usually
    “C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program”
    (where the KSP_x64.exe file is located).
