The PB-X50R Xenon Container is a radially attachable xenon gas tank for the IX-6315 "Dawn" Electric Propulsion System that contains 405 units of xenon. The part was added in version 0.21 of KSP.

Product description

The X50R is a small-volume Xenon container, heralded by engineers for being ideally suited for small ion-driven spacecraft, and also for having thoroughly disproved management in their notion that a smaller fuel tank would make the fuel cheaper.



  • The PB-X150 Xenon Container by Probodobodyne Inc (introduced in version 0.18) is very similarly named but the PB-X50R is listed as "Found lying by the side of the road" rather than manufactured by Probodobodyne.
  • This part was originally from a mod called KSPX. The developer of KSPX eventually joined Squad and the KSP dev team and many parts from KSPX are now included in the stock game.


  • Decreased tech cost from 9600 to 7800
  • Increased cost from 2200 to 2220
  • Decreased mass from 0.03143 to 0.0135
  • Monopropellant supply increased from 400 to 405
  • Moved to Propulsion from Utility.
