Notes: The Xindi weapon sphere was a result of the collaboration of all five Xindi species in the 22nd century, to defend themselves from humans in the future, by destroying Earth before they became a threat. Three different versions of the weapon were built. The first prototype was used against Earth and killed seven million people on the surface. The prototype was manned by a single pilot and possessed a powerful partial beam weapon. The second prototype, twice the size of the first, was capable of destroying a small moon. This weapon was stolen by the Andorians until the self destruct codes were entered. The final and most powerful version was capable of destroying a planet. The Xindi weapon was destroyed in Earth orbit by the NX-01 Enterprise crew.
