Programs to deploy weapons in orbital space have important implications for international relations.In this paper, we analyze the constitutive logic of three modes of space weaponization currently being pursued by the United States – space-based missile defense, space control, and force application from orbital space.We show that these technologies of killing, when bundled together, constitute a new form of centralized sovereign power in a context of de-territorialized sovereignty.This is a new type of international political society, which we call empire of the future, distinct from and more ominous than the de-centralized form of Empire theorized by Hardt and Negri and the modern expression of classical hegemony now widely debated in discussions of putative American empire.
