There is a critical shift in the nature of modern warfare. The dual-use satellites power civilian life, but at the same time are increasingly becoming instruments of covert warfare. There is growing weaponisation of civilian space infrastructure without physical destruction. Unlike earlier conceptions of space war involving kinetic attacks, recent developments show a shift toward cyber-attacks, signal jamming, and spoofing, as seen during the Russia-Ukraine conflict (2022) where the Viasat KA-SAT network was disrupted, crippling communications across Europe. This marks a paradigm shift, from visible destruction to invisible disruption. 

What are Dual-use satellites?

1. They are platforms that serve both civilian/commercial and military/national security purposes, often simultaneously or interchangeably. 
2. These technologies, such as Earth observation or communication satellites, provide commercial services (e.g., mapping, internet) while also supplying intelligence-grade imagery, navigation, and encrypted communications for defense forces.

How are dual-use satellites transforming the nature of warfare?

1. Dual-use infrastructure: Enables simultaneous civilian and military utilisation of GPS, broadband, and communication systems.
2. Military integration: Facilitates intelligence gathering, surveillance, reconnaissance, and drone targeting.
3. Operational dependency: Increases reliance of armed forces on commercial satellite constellations.
4. Target ambiguity: Obscures distinction between legitimate military targets and protected civilian assets.
5. Strategic leverage: Converts civilian systems into force multipliers without dedicated military deployment
6. Example: Civilian GPS systems enabling precision-guided military operations

Why does modern space conflict avoid physical destruction?

1. Non-kinetic techniques: Utilises cyberattacks, signal jamming, spoofing, and hacking
2. Debris avoidance: Prevents creation of orbital debris that can damage own satellites
3. Cost efficiency: Reduces financial and technological burden compared to kinetic weapons
4. Escalation control: Maintains conflict below threshold of overt war
5. Reversibility: Allows temporary disruption instead of permanent destruction
6. Example: Viasat KA-SAT cyberattack disrupted communications without physical damage.

How does the invisibility of cyber warfare weaken deterrence?

1. Attribution uncertainty: Limits ability to conclusively identify attackers
2. Proxy warfare: Enables operations through third-party actors and intermediaries
3. Evidentiary challenges: Lacks visible proof compared to physical attacks
4. Delayed response: Slows decision-making for retaliation due to ambiguity
5. Deterrence erosion: Weakens threat of retaliation as attackers remain unidentified
6. Outcome: Encourages repeated low-intensity attacks below war threshold

Why is the legal framework inadequate for space cyber warfare?

1. Outer Space Treaty gap: Focuses on physical weaponisation, excludes cyber operations
2. UN Charter ambiguity: Article 2(4) unclear on cyber disruptions as “use of force”
3. International Humanitarian Law (IHL) limitations: Difficulty in applying civilian-military distinction in dual-use systems.
4. Attribution requirement: Legal responsibility contingent on high evidentiary standards.
5. Enforcement deficit: Absence of binding mechanisms for compliance and accountability
6. Example: Cyberattacks on satellites fall outside clearly defined war thresholds

How is the civilian-military distinction collapsing in space?

1. Dual-use systems: Civilian satellites routinely support military operations
2. Legal contradiction: IHL mandates distinction, but technology merges functions
3. Operational overlap: Commercial constellations provide services to armed forces
4. Target legitimacy confusion: Civilian assets become potential military targets
5. Protection erosion: Reduces safeguards for civilian infrastructure
6. Example: Commercial satellites used for intelligence and battlefield coordination

What risks do cyber intrusions in space systems pose to society?

1. Critical infrastructure exposure: Financial systems, aviation, and energy depend on satellites
2. Cascading failures: Disruption in one system triggers failures across sectors
3. Navigation risks: GPS spoofing misguides aircraft and maritime vessels
4. Economic disruption: Interrupts banking, stock markets, and digital payments
5. Governance paralysis: Affects emergency services and state communication networks
6. Example: Communication blackout due to satellite cyberattack affecting multiple countries.

Why is there a need for enforceable norms in space governance?

1. Normative gaps: Existing frameworks remain advisory without enforcement
2. Threshold ambiguity: Lack of clarity on what constitutes an act of war in cyberspace
3. Attribution mechanisms: Requires international cooperation for real-time identification
4. Collective security: Strengthens coordinated response to cross-border cyber threats
5. Standardisation: Establishes clear operational and legal guidelines for space conduct
6. Outcome: Reduces ambiguity and strengthens deterrence

Conclusion

Space warfare is evolving into a domain defined by invisible disruption, legal ambiguity, and systemic risk. The fusion of civilian and military systems creates vulnerabilities that extend beyond conflict zones into everyday life. Strengthening legal clarity, attribution capacity, and enforceable norms remains essential for maintaining stability in the space domain.
