Report Space Security Report: Space Threat Assessment 2020 PublishedMarch 30, 2020 By Todd Harrison, Kaitlyn Johnson, Thomas G. Roberts, Tyler Way, Makena Young Download PDF For an interactive executive summary of the Space Threat Assessment 2020, please visit here. While the vulnerabilities of U.S. national security space systems are often discussed publicly, the progress other nations are making in counterspace systems is not as readily accessible. Space Threat Assessment 2020 is intended to raise awareness and understanding of the threats, debunk myths and misinformation, and highlight areas in which senior leaders and policymakers should focus more attention. The purpose of this annual report from the CSIS Aerospace Security Project is to aggregate and analyze publicly available information on the counterspace capabilities of other nations, serving as a review of open-source information available on the counterspace capabilities that can threaten U.S. space systems. Space Threat Assessment 2020 focuses on the capabilities of China, Russia, Iran, North Korea, and India, and this year’s report places relatively more emphasis than previous years on the counterspace capabilities of select other countries, including some allies and partners of the United States. This report is not a comprehensive assessment of all known threats to U.S. space systems because much of the information on what other countries are doing to advance their counterspace systems is not publicly available. Instead, it serves as an unclassified assessment that aggregates and highlights open-source information on counterspace capabilities for policymakers and the general public. The information in this report is current as of February 22, 2020.
