Space Security and Strategic Competition
Militarisation of Space
There is an important conceptual distinction you must remember: Militarisation vs. Weaponisation.
Militarisation is using space to SUPPORT military operations — like using GPS for troop coordination.
Weaponisation is placing or using WEAPONS in space itself. The Outer Space Treaty (1967) does not ban militarisation. It only bans WMDs in orbit. This gap is the source of most current space security tensions.
Militarisation = Use of space for military SUPPORT functions (non-weapon role) — surveillance, communication, navigation, early warning.
Types of Military Satellites
| Type | Function | Example |
| Surveillance satellites | High-resolution imagery — troop movements, infrastructure monitoring | KH-series (USA) |
| Early warning satellites | Infrared sensors detect missile launches (heat signatures) — nuclear deterrence | DSP (USA) |
| Military comm. satellites | Secure, encrypted, jam-resistant communication for armed forces | Milstar (USA) |
| Navigation satellites | Precise positioning for missile targeting, precision strikes | GPS (USA), NavIC (India) |
| ELINT satellites | Intercept radar signals, map enemy air defences, electronic warfare | Various |
Key Shift: Military satellites have transformed warfare from platform-centric operations (tanks, ships, aircraft) to information-centric operations — space dominance = military dominance.
Weaponisation of Space
Weaponisation = Deployment or USE of weapons IN or FROM space — making space an active combat domain.
Anti-Satellite (ASAT) Capabilities
- USA, Russia, China, and India (the only four in the world).
Types of ASAT Systems
| Type | Mechanism | Key Feature | Example |
| Direct-Ascent (Kinetic Kill) | Ground-launched missile; kinetic energy destroys satellite | Generates significant debris — major environmental concern | India’s Mission Shakti (2019) |
| Co-Orbital ASAT | Satellite maneuvered close to target; disables via collision/explosion/electronic disruption | Hard to detect; blurs line between civilian and military satellites | Russia’s Kosmos programme |
| Non-Kinetic ASAT | Electronic jamming, cyberattacks, laser dazzling/blinding | No physical destruction; no debris creation; deniable | Viasat cyberattack (2022) |
Strategic Significance of ASAT Systems
- Deterrence Tool: ASAT capability acts as a deterrent by demonstrating advanced technological and military strength.
- Counter-Space Capability: ASAT weapons can disable or destroy enemy satellites supporting communication, navigation, surveillance, and missile operations.
- Strategic Leverage: Disrupting an adversary’s space assets can significantly weaken its military effectiveness and decision-making during conflicts.
Key Concerns of ASAT Systems
- Space Debris Creation: Destructive ASAT tests generate orbital debris that threatens satellites and other space missions.
- Escalation Risk: Attacks on space assets can trigger retaliation and expand conflicts across multiple domains.
- Legal Grey Area: International law restricts WMDs in space but does not explicitly prohibit conventional ASAT systems, creating regulatory ambiguity.
Mission Shakti (2019) — India’s ASAT Test ⭐
On 27 March 2019, India quietly demonstrated that it belongs among the world’s most advanced space powers. Mission Shakti was not just a scientific achievement — it was a strategic declaration. India now has the capability to deny adversaries the use of space-based assets during conflict.
- Conducted by: DRDO under India’s Ballistic Missile Defence programme.
- Target: Microsat-R — an Indian satellite deliberately placed in LEO for the test.
- Missile: Modified BMD interceptor — Prithvi Defence Vehicle Mark-II (PDV Mk-II).
- Launch site: Dr. A.P.J. Abdul Kalam Island, Odisha.
- Altitude: ~282–300 km — low altitude chosen to ensure faster atmospheric decay of debris.
- Historic: Made India the 4th country with ASAT capability (after USA, Russia/USSR, China).
Other Weaponisation Methods
- Space-Based Missile Interceptors: Proposed orbital systems designed to destroy ballistic missiles during their flight, especially in the boost phase.
- Orbital Strike Systems: Conceptual space-based weapons intended to attack terrestrial targets from orbit using kinetic or directed-energy means.
- Kinetic Bombardment (Rods from God): A theoretical weapon that uses high-speed metal rods dropped from orbit to inflict massive damage through kinetic energy alone.
- Space-Based Directed Energy Weapons (DEWs): Experimental or proposed orbital weapons that use powerful lasers or particle beams to neutralize targets in space or on Earth.
⭐ Outer Space Treaty (1967) prohibits WMDs in space but does NOT explicitly ban conventional weapons or ASAT systems — creating a dangerous legal grey area.
Technological Dependence and Strategic Vulnerability
Switch off all GPS signals right now — for just 48 hours. What happens? Aircraft navigation goes blind, ships lose positioning, ATMs struggle to timestamp transactions, 4G/5G networks lose synchronisation, military drones lose precision guidance, and emergency services lose real-time location tracking. This is not science fiction — it is the satellite-dependent world we have built without fully appreciating the vulnerability we have created.
Growing Dependence on Satellites
| Sector | Satellite Dependency |
| Aviation & Maritime | GPS for navigation, weather routing, collision avoidance |
| Banking & Finance | Precise satellite timing for transaction timestamps, ATM sync, stock trading |
| Telecom & Internet | 4G/5G network synchronisation requires nanosecond GPS timing |
| Weather & Disaster | Satellite imagery, precipitation data, cyclone tracking, early warning systems |
| Defence & Security | Surveillance, missile guidance, troop coordination, SIGINT |
Vulnerabilities of Space Infrastructure
- Physical Threats: Space debris, ASAT attacks, and orbital congestion can damage or destroy satellites.
- Electronic and Cyber Threats: Jamming, spoofing, and cyberattacks can disrupt or compromise satellite operations and services.
- Solar and Space Weather Events: Solar storms can interfere with satellite systems, communications, navigation, and terrestrial infrastructure.
Strategic Concerns of Space Infrastructure Dependence
- Economic Disruption: Failure of satellite services can severely affect trade, navigation, digital payments, and supply chains.
- National Security Risk: Disruption of satellite networks can undermine military intelligence, surveillance, and communications.
- Infrastructure Paralysis: Critical services such as power, telecommunications, banking, and transport depend heavily on satellite support.
- Global Power Competition: Growing counter-space capabilities increase geopolitical tensions and complicate conflict management.
Space Race and Geopolitics
The Cold War space race was a two-horse race between the USA and USSR — each trying to show that their ideology produced superior science. Today’s space race is a multi-horse marathon: USA, China, Russia, India, Europe, Japan, and dozens of private companies are all running simultaneously, in different directions, with different goals, and with no clear referee. This is far more complex — and far more consequential — than what came before.
Phases of the Space Race
| Phase | Period | Key Features | Defining Moment |
| Cold War Space Race | 1957–1991 | USA vs USSR; ideological & technological rivalry | Sputnik (1957) → Apollo 11 (1969) |
| Post-Cold War Phase | 1991–2000s | New players enter; shift from rivalry to cooperation | ISS (1998); China, India join space club |
| New Space Race | 2010s–Present | Multipolar competition + private sector boom | SpaceX reusability; Chandrayaan-3 south pole; China Tiangong station |
