Karakum was assigned as a Black Operations ship operating in the Belt and outer planets.
Karakum was dispatched to Ganymede following the Martian takeover of Ganymede Station and establishment of a no-fly zone around the planet. The ship was ordered to land on the moon's surface close to the lab in which the Hybrid was created, with its flight plan broadcast to all MCRN vessels in the system with instructions not to interfere with the vessel under any circumstances.
The ship was to have taken control of Project Caliban materials for the MCR, however it was ultimately destroyed by United Nations Navy forces acting under the orders of Sadavir Errinwright before it could reach its destination.
The ship's destruction would accelerate the breakdown and collapse of Ganymede Station and would trigger a new round of fighting between UN and MCR forces in the Jovian System and lead to the UN-MCR War.
- This vessel does not appear in the novels. Mars may have sought it but Mars did not achieve access to the protomolecule in Caliban's War.
