Recently, dual-use satellites blurred civilian-military distinctions, raising concerns under the Outer Space Treaty and international humanitarian law.
About Dual-Use Satellites
- Dual-use satellites are space systems that serve both civilian and military purposes, making them central to modern communication, navigation, and warfare.

Recent Space Tech Warfare
- United States: The United States is developing orbital cargo drop vehicles to rapidly deliver military logistics or weapons via low Earth orbit.
- China: China has developed the TPG1000Cs high-power microwave system capable of disabling satellite electronics through intense energy pulses without creating debris.
- India: India is advancing counterspace capabilities through the Defence Space Research Agency, including ISR integration and DRDO’s laser-based directed-energy weapon (DEW MK-II(A)) tested in 2025.
- Europe: Europe is deploying NAVISHIELD anti-jamming systems to protect satellite navigation signals like Galileo and GPS from interference.

Role of Dual-Use Satellites in Modern Warfare
- Civilian–Military Convergence: Dual-use satellites integrate civilian and military functions, as commercial systems like Starlink enable both public communication and battlefield coordination in conflicts like Ukraine.
- Backbone of Critical Infrastructure: Satellites underpin essential systems such as GPS, banking, and telecom, where GPS timing enables global financial transactions, making them strategic assets in warfare.
- Enablers of Non-Kinetic Warfare: Modern conflicts rely on jamming, spoofing, and cyberattacks, as seen in the 2022 Viasat KA-SAT cyberattack that disrupted communications without physical destruction.
- Global and Transnational Impact: Satellite networks operate across borders, so disruptions like GPS spoofing can simultaneously affect ships and aircraft across multiple regions.
- High Strategic Dependency and Cascading Risks: Heavy reliance on satellites means disruptions can cascade across sectors, with communication failures paralysing emergency services, governance, and economic systems.
International Regulations on Warfare in Space
- Outer Space Treaty: Adopted in 1967, it forms the foundation of space law.
- It mandates peaceful use of outer space and prohibits placement of nuclear or other Weapons of Mass Destruction (WMDs) in orbit.
- It establishes that space is the “province of all mankind,” ensuring non-appropriation by states and promoting international cooperation, though it lacks provisions on cyber or dual-use systems.
- United Nations Charter (Article 2(4)): Adopted in 1945, it prohibits the threat or use of force against territorial integrity or political independence of states.
- It underpins global security and sovereignty norms.
- However, it remains ambiguous on whether cyber operations, including satellite disruption, qualify as “use of force.”
- International Humanitarian Law (Geneva Conventions): Adopted in 1949, it governs conduct during armed conflict.
- It emphasises principles of distinction, proportionality, and necessity to protect civilians.
- Dual-use satellites challenge this framework by blurring lines between civilian and military targets.

Challenges
- Legal Gaps in Space Governance: Existing frameworks like the Outer Space Treaty and United Nations Charter do not adequately address cyberattacks or dual-use satellites, creating regulatory blind spots in modern space conflict.
- Technological Asymmetry: Space capabilities are concentrated among a few advanced nations, leading to unequal access and increasing dependence of developing countries on foreign commercial satellite networks.
- Weak Attribution Mechanisms: Cyber operations in space are difficult to trace due to spoofing and proxy networks, creating an “attribution gap” that undermines accountability and deterrence under international law.
- Increasing Militarisation of Space: Growing reliance on satellites for military operations, including intelligence and targeting, is transforming space into a contested strategic domain despite its peaceful-use principles.ition.

Way Forward
- Clarifying Legal Norms: Develop international consensus on cyber operations as “use of force” in space.
- Secure-by-Design Systems: Adopt cybersecurity frameworks across satellite lifecycle.
- Strengthening Global Cooperation: Enhance information sharing and attribution mechanisms among nations.
Conclusion
Dual-use satellites are redefining warfare, demanding updated laws and stronger cybersecurity to balance innovation, security, and protection of civilian infrastructure in space.
