Space Threat Assessment 2023

Welcome to the sixth edition of Space Threat Assessment by the Aerospace Security Project at the Center for Strategic and International Studies (CSIS). This resource for policymakers and the public leverages open-source information to assess key developments in foreign counterspace weapons. Drawing on six years of collected data and analyses, this series describes trends in the development, testing, and use of counterspace weapons and enables readers to develop a deeper understanding of threats to U.S. national security interests in space. The past year was dominated by the Russian invasion of Ukraine, where space capabilities, including commercial satellites, played a highly visible and compelling role in Ukraine’s resistance to the invasion. Thus, this year’s featured analysis provides an in-depth look at Russia’s battlefield employment of counterspace weapons. As space capabilities continue to demonstrate their utility, from peacetime to conflict, it should come as no surprise that adversaries seek to block their use.
