Universal Storage II [1.3.1 and 1.4.5 - 1.7.0]

Paul Kingtiger

Recommended Posts

Universal Storage is a modular parts mod, allowing you to build custom service modules.  It is highly integrated with the most popular life support mods, DMagic Orbital Science, and Kerbal Inventory System.

Part library and more information available at kingtiger.co.uk/uvsii

Universal Storage II (UvSii) is the follow up to KSP’s original wedge based parts mod,  Service modules are build from a central core, around which you can place various resource and processor wedges.  Customization fairings complete the service module, providing aerodynamic shielding with access via payload doors. Most parts are resizable allowing increased storage capacity while keeping part counts low.

New features

  • Separate fairing parts provide full comparability with the stock aerodynamics system.
  • Parts feature multiple height variants allowing greater capacity without bloating part count.
  • Fairings feature multiple paint variants, allowing you to match the look of your craft.
  • Full KSPedia articles including animated gifs.
  • Localization support including KSPedia.


You can post bugs and feature requests on our bitbucket issue tracker: https://bitbucket.org/uvs2/universalstorage2

Or post in this thread and we'll do our best to help you (using bitbucket makes it easier for us to help and is preferred).

Download at Space Dock

You can download the mod at SpaceDock.  There is a separate version for KSP 1.3.1 so make sure you download the correct file. 
Use the 
changelog button on SpaceDock to view each version.


Three step build process

Service modules are built from three basic parts.  The core provides the structure with space to attach payload wedges and the fairing provides aerodynamic shielding.  For more information on the build process check KSPedia in game.


Multiple configurations

Most parts have multiple height options, allowing increased resource storage without bloating part count.  Cost, mass and capacity all scale linearly so every configuration is balanced.

Larger cores and fairings have multiple configurations.  The cores feature a central fuel tank or a crew transfer tunnel (for use with Connected Living Space).  Selected fairings can be configured as a payload bay for use without a core or wedges.

Fairings can be configured to match the look of your craft, with either Porkjet, Gemini, Apollo or Saturn paint schemes.


Designed to work with 3rd party mods

Built from the ground up to provide resource storage for popular life support mods.  The game will automatically detect which mods you have installed (via module manager) and load payload wedges to match.  In addition, Universal Storage is closely linked with DMagic Orbital science to provide a large selection of wedge format science experiments when both are installed.  Wedges are Kerbal Inventory System (KIS) compatible, allowing Kerbals on EVA to swap out wedges as part of a resupply mission.

Compatible mods


Full KSPedia support provides in-game information on the parts, their features and how to build craft.  The mod includes support for animated gifs in KSPedia pages (see source code for detailed information).


Career mode support

The mod is fully compatible with career mode, with parts balanced against their non-wedge equivalents ensuring there are no ‘cheat’ parts.  Part unlocking follows a logical progression with the majority of parts available at tier five and six.

Source Code

Universal Storage Source Code


  1. Nothing works like it should!
    Make sure you have the correct version of the mod to match your KSP install.  KSP 1.3.1 and KSP 1.4 (and later) versions have different requirements.  You can find and download the correct version of the mod using the links above.  If you have made a mistake, Delete the Module Manager file and the Universal Storage II folder in your GameData folder and try again. 

  2. Check KSPedia!
    Answers to the most common questions are in game via KSPedia.

  3. There is a problem with X science experiment!
    Universal Storage II does now contains basic science parts, which are augmented by DMagic Orbital Science, a separate mod.  If you have a problem with a science part make sure you include the name so we know who to ask for help.  DMagic is one the Universal Storage team so he checks this thread, alternatively you can check the Orbital Science thread for support.
  4. How do I install the mod?
    Download the file and unzip it.  Then copy the GameData folder to your Kerbal Space Program folder, merging / overwriting any files when asked.

  5. Can I have Universal Storage and Universal Storage 2 installed together?
    Yes, the two mods are entirely separate and will work side by side.  The parts list in the VAB will be a little cluttered, and I recommend completing any missions using the old mod, recovering the craft, then removing Universal Storage (simply delete the folder from your GameData file).  You can then continue just using Universal Storage 2.

  6. How can I find the parts.
    The cores and fairings are found in the Payload category.  Fuel tanks and Batteries are found under Fuel Tanks and Electrics.  Most other parts are under Utility.  However the easiest way to find the parts is to type Universal in the search box.

  7. How do I remove the mod?
    Simply delete the Universal Storage 2 folder in GameData.  Note that any craft using parts from the mod will break, so make sure you have recovered and craft using Universal Storage II parts before removing the mod.

  8. How do I upgrade the mod?
    Simply download the new version and install as above, overwriting any existing files.

  9. How did you balance the parts?
    The original Universal Storage parts were balanced against real world craft and technology.  This made for realistic parts, but many were badly balanced against other parts in game.  For Universal Storage II we decided to balance parts against the stock parts in game or the various life support mods.  This ensures that costs, mass and capacity are balanced against the rest of the game, so there's are no 'cheat' parts.

I hope you don't want to reserve more posts :P

The parts looking amazing, can't wait to play around with them. And already compatible with Kerbalism and Orbital Science? I love it!

Great work, thank you guys :)

Btw.: Found a little typo in the OP:

Thanks @Daishi and @Paul Kingtiger for all your hard work. These new toys look nice and shiny. Can't wait to try them!

Thank you for your hard work with the translations.

Don't forget @DMagic he is very much an equal partner on Universal Storage 2.  Many of the advanced features are due to his plug-in coding, not to mention KSPedia (with localization and animation support)

Note that DMagic Orbital Science doesn't support this version of US yet. It will need to be updated with new versions of the US science parts before they can be used with this mod.


Also, make sure to ping me if anyone runs into bugs, errors, or any questions about how the Universal Storage (they all start with US) part modules are setup in the configs.

What if I has the 1st US mod installed? I have several things in orbit that have those parts. Is this independent? Can I use both until I phase out the old stuff?

The mods are completely separate and part names are different so they should run side by side without any problems.
Take a backup of your save file just in case and let us know if you run into any problems.

Part balance might be a little odd as US1 was balanced against real world tech and UvSii is balanced against Stock KSP and the various life support mods.

Any plans to add tanks and batteries for the tapered fairing (0.625m to 1.25m)?

Of the 3 configurations:
Wedge Bracket: Allows you to mount a single wedge
Structural: Works like a stock bay, surface attach parts
Crew Tunnel: Connected Living Space compatible (allows crew transfer)

I don't think we're going to add any more variants to that, it would get too cluttered.  But you can use fuel / Battery wedges or surface mount any part that fits.
