Description
Having found the mysterious Kerbal XX circling Duna, the Kerbal Space Program immediately set to work on making it a useable vehicle for everyday use.
By mating the Kerbal XX with the core and booster stages of the workhorse Kerbal X rocket (and adding additional safety parachutes), they produced the craft known, naturally, as the Kerbal XXX.
A stock rocket called Kerbal XXX. Built with 95 of the finest parts, its root part is mk1-3pod.
Built in the VAB in KSP version 1.10.0.
(For more information about the Kerbal XX, see here; a picture can be found here, albeit one from several versions ago.)
