What Are the Biggest Space Threats in 2026?

Why It Matters

Escalating counter‑space capabilities threaten global communications and intelligence, forcing governments and industry to rethink security, deterrence, and the civilian‑military divide in space.

Key Takeaways

• Space has become central to modern military competition and operations
• Nations expand counter‑space tools: RPO, jamming, cyber, directed energy
• China and Russia intensify on‑orbit maneuvers and anti‑satellite tests
• Europe boosts defense budgets, adopts dual‑use space security mandates
• Commercial constellations like Starlink become contested military assets

Summary

The CSIS panel examined the 2025‑2026 space threat landscape, highlighting how space has shifted from a support role to a strategic battlefield. Nations increasingly rely on satellites for communications, navigation, and targeting, while simultaneously developing capabilities to disrupt, degrade, or destroy those assets. Key insights include a proliferation of counter‑space technologies—co‑orbital rendezvous, direct‑ascent weapons, electronic warfare, directed‑energy, and cyber tools—now fielded by at least 13 countries. China and Russia dominate on‑orbit activities, conducting sophisticated rendezvous‑proximity operations and testing anti‑satellite systems, while the United States, India, France, Germany, Japan and the United Kingdom update military space doctrines and budgets. Notable remarks from Victoria Sampson emphasized the “stoplight chart” that grades national activities, and Kathleen Brett pointed to Europe’s new dual‑use mandate for the ESA and France’s €4.2 billion space‑defense allocation. Clayton Swope warned that the incremental escalation resembles a “boiling frog,” where incremental advances may soon reach a tipping point. The implications are clear: policymakers must address the blurred line between civilian and military satellites, develop norms for on‑orbit behavior, and invest in resilience to protect commercial constellations that now underpin critical defense operations.

Original Description

Please join the Center for Strategic and International Studies (CSIS) Aerospace Security Project and Secure World Foundation (SWF) for a discussion on the evolving space threat environment and the latest trends in global counterspace capabilities.

Kari A. Bingen, director of the CSIS Aerospace Security Project, will moderate a conversation with Clayton Swope, deputy director of the Aerospace Security Project; Victoria Samson, Chief Director, Space Security and Stability, SWF; and Kathleen Brett, Program Analyst, Space Security and Stability, SWF. Together, they will assess the 2026 space threats landscape, examine recent developments in counterspace capabilities, and discuss the implications for space security and stability in the years ahead.

This event is made possible by general support to CSIS.
