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 2019 reviews the open-source information available on the counterspace capabilities that can threaten U.S. space systems. The report 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 their attention.
Space Threat Assessment 2019 focuses on four specific countries that pose the greatest risk for the United States: China, Russia, Iran, and North Korea. A fifth section analyzes the counterspace capabilities of select other countries, including some allies and partners of the United States, and some non-state actors. 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.
