store your vessels until they are needed

Hangars are parts that can store whole ships inside. Stored ships are not docked but unloaded, which reduces part count considerably, improving framerate and memory footprint while allowing to carry out missions of great complexity.

Aside from the hangars themselves the mod provides a set of utility parts that help in various usage scenarios. To further reduce part count, most parts (including hangars) have multiple integrated modules and resources that are balanced and often eliminate the need to add such things as batteries, lights, generators, probe cores and reaction wheels.


  • Many different types of hangars for any application
  • Most hangars may be rescaled to the needed size and proportions via tweakables
  • Ships could be stored in hangars at construction time
  • Crew and resources can be transferred between a ship with a hangar and stored ships
  • Ground hangars have anchors for comfort use on low-gravity worlds
  • An asteroid can also be stored in a hangar. If it fits, of course.
  • And vice versa: a hangar can be made inside and asteroid!
  • In addition, many utility parts are provided to help in various usage scenarios.

Downloads and Installation

Delete the old version of the mod before installing the new one.

You may keep the Hangar.user and config.xml files to retain your preferences.

Before any upgrade I recommend you to backup your saves.

Releases are available from:

  • CKAN support is pending
  • GitHub (all releases, optional packages and the source code)

Before using a hangar study the list of modules that are integrated into it (RMB on part's icon). Many of the hangars have plenty of modules (like batteries, command modules, fuel tanks, etc.) to reduce part count. Don't worry, all is balanced by weight and cost, no cheating.

Known Issues

  • GUI:
    • Dropdown lists show vertical scrollbars when there are too many items. But due to the implemented click-through prevention mechanism the scrollbars cannot be moved by mouse cursor; use mouse wheel instead. And curse Unity3D for the poor GUI API.
  • Rovers:
    • Rovers stored in editor have somewhat smaller dimensions due to inactive suspension of the wheels. So if you pack several rovers tightly into a hangar, and than launch one of them, the launched rover sometimes cannot be stored again into that same hangar with the "No room ..." message. Again: it's no bug, calculations are performed correctly, the rover's just got bigger.
  • Mod Conflicts: none at the moment.
  • Other:
    • Removing Hangar in career mode sometimes corrupts the savegame (the user cannot enter VAB/SPH and so on). This is due to a bug in KSP and should also affect any mod that has its own Agent for Contracts. To fix such savegame see this HOWTO


Recommended mods

  • Extraplanetary Launchpads: big ground hangars are not suitable as parts for vessel construction and are too heavy to launch anyway. So the only meaningful way to use them is to build them on site.
  • Throttle Controlled Avionics: if you're planning to build VTOLs and hovercrafts with spaceplane hangars, this mod (which I currently maintain) will help greatly as it ads automatic thrust balancing and altitude control.
  • Editor Extensions: invaluable for vessel design. Even considering 0.90 editor improvements.

Supported mods

Hangar supports KSP Addon Version Checker.

And some functionality and parts are added if the following mods are installed:

  • TAC Life Support v0.10.+ adds life support resources and systems to inhabitable hangars,
  • RemoteTech adds RT antennas and SPUs to controllable hangars,
  • AntennaRange adds limited data transmitters to all hangars with integrated probe cores (thanks to Kerbas-ad-astra),
  • Deadly Reentry adds Ablative Shielding resource to heatshields,
  • Extraplanetary Launchpads adds a new Heavy Recycler model that fits the style of hangars.
  • MKS/OKS adds the Substrate Mixer -- a converter that allows to turn useless Silicates and Waste into a useful Substrate resource.

Unsupported Mods

  • Asteroid Recycling Technologies are not compatible with the Asteroid Hangars framework. Both mods can be installed at the same time, but you cannot use the same asteroid both as a hangar and by ART machinery.

Version 3.5.0 for Kerbal Space Program 1.8.1

Released on 2019-12-21

  • Magnetic Dampers
    • All hangars except for VTOL and fairings now have the ATMagneticDamper module.
    • It can be switched on/off even remotely.
    • Its attenuation can also be changed in PAW in flight.
    • Orbital hangars also have attractors, i.e. they not only damp velocity of vessels within their premises, but can also pull them in and dock them inside automatically.
    • The polarity of the attractor could be changed remotely, so a vessel launched from an orbital hangar can order the hangar to push it slowly outside. Much like with the "Launch with Punch" option, but the vessel is physically controlled all the way by the hangar.
    • Damper works in Time Warp, so a vessel that is left inside the hangar's docking space will not fly though its walls anymore.
    • The damper is controlled by the hangar in that it is automatically activated on launch and, in case of the orbital hangars, on hangar activation. This helps a lot with launching heavy-with-many-parts rovers and planes that tend to jump on their wheels and explode. Should also help with sliding issues mentioned on the forum.
  • Hagar window remembers its visibility per vessel.
  • When Configurable Containers are installed, the Universal Fuel Tank is added to fuel tanks. It is basically the Procedural Adapter with Tank Manager and LFO tanks by default.
  • Rover Lander and Mk3 Hangar both spawn vessels at the floor now. No more falling from the center of the hangar.
  • Updated the Square Heatshields' configs to be more stock-like
  • Moved Square Heatshields to Thermal category
  • Moved non-ground and non-inflatible hangars to Payload category
  • Fixed the problem with Hangar Gateway that was missing the storage in mined asteroids after game reloading or vessel switching.
  • Fixed the problem with exploding vessels, when launched in very tight quarters, i.e. with some parts of the launched vessel mere centimeters away from the hangar walls.
  • Fixed directions of RCS plumes on the Hangar Gateway
  • Fixed costs of square heatshield
  • Fixed the problem with automatic game saves before vessel spawning.
  • Various fixes and adaptations to AT_Utils API changes.

Version 3.4.1 for Kerbal Space Program 1.8.1

Released on 2019-11-30

  • Updated Tech Tree limits for Size and Aspect:
    • General Construction: size/aspect [0.75, 1.5]
    • Miniaturization: size/aspect [0.5
    • Precision Engineering: size/aspect [0.1
    • Advanced Construction: size/aspect 3]
    • Specialized Construction: size/aspect 6]
    • Composites: size/aspect 12]
    • Meta Materials: size/aspect 1000]
  • Hopefully fixed aerodynamics of stock cargo bays that are patched to be hangars instead.
  • For modders:
    • onLaunchedFromHangar provides additional bool fromFairings == true data field when a vessel is launched from HangarFairings module. This may be needed, because in this case the launched vessel should behave as if it was just the next stage of the carrier.

Version 3.4.0 for Kerbal Space Program 1.8.1

Released on 2019-11-14


  • Supports KSP-1.8.1
  • Hangar contents may be rotated both in Editor and in Flight
    • Payload may be rotated in 90 degree steps using the dedicated UI. The orientation is indicated by a translucent arrow drawn along with the content hint. The arrow indicates the bottom and front directions of the payload.
    • In Flight rotation is allowed only if the rotated payload fits inside docking space. And disabled for fairings and single-use hangars.
    • Orientation of each stored vessel is preserved, so if you have docked (in flight), say, nose-forward, that is how the vessel will be launched, unless rotated manually before launch. Note: the orientation will be actually slightly corrected, so that the stored vessel is aligned with the hangar.
    • When a stored vessel is transferred from one storage to the other its orientation is set to the optimal one for the receiving storage.
  • Mobile Smelter is deprecated in favor of the ISRUs. As usual, parts already in flight will be functional, but it wouldn't be available in Editor.
  • Asteroid Hatch creates resource tanks using Material Kits. Existing hatches will still use Metals, only the new parts will be affected. Tanks will cost slightly more, but will weight the same.
  • ISRUs are patched to produce Material Kits the same way they do in Global Construction (unless MKS is installed).
  • Vessels stored in Editor are not spawned-and-stored anymore during the launch, which caused considerable lag.
  • Hangars don't launch stored vessels if any physical object is present within their docking space.
  • Vessel docking is triggered only with dedicated trigger-colliders, rather than with any trigger-colliders on the part, like airlocks and ladders.
  • Added Show Payload button to part menu of fairings to show their content as they don't have the Hangar Window interface.
  • Numerous bugfixes and improvements:
    • Localizing vessel names.
    • Fixed NRE in case a jettisoned fairing is destroyed immediately.
    • Update content_hull_mesh on hangar resize.
    • Fixed UI not showing after launch from hangar if it was destroyed before launch ended.
    • Several performance improvements due to the use of the frameworks from AT_Utils rather than the legacy Hangar code.
    • Showing tooltips in HangarEditor.
    • Added random angular velocities to debris jettisoned from fairings for visual effect.
    • Limit the jettison force for parts decoupled form a fairing when it is itself jettisoned.
    • Fixed content highlighting in Hangar Gateway.
    • Improved hangar fairings texture and model.
    • Removed deprecated Readme.pdf from the distribution.
  • For modders (and for future integration with TCA):
    • Sending the Hangar PartModule as onLaunchedFromHangar KSPEvent to all parts of the launched vessel.
