India Launches ₹26,968 Cr Space Surveillance Program with 52 Defence Satellites to monitor the world
₹26,968 crore SBS Phase 3 project aims to transform India’s defence with advanced surveillance from space
New Delhi, July 1, 2025 — India is making a historic pivot in its national security strategy with a new plan to launch 52 military surveillance satellites by the end of this decade. The ₹26,968 crore (approximately $3.2 billion USD) initiative, under Phase 3 of the Space-Based Surveillance (SBS) program, marks India’s most ambitious defence space project to date, aiming to create round-the-clock intelligence coverage across its land and maritime borders.
The project is designed to enable India to monitor adversarial build-ups deep inside enemy territory, enhance maritime domain awareness, and reduce satellite revisit times drastically, thus placing India among the elite few global powers actively militarizing outer space for strategic deterrence.
Why This Move Now? Lessons from Operation Sindoor
The push comes in the wake of Operation Sindoor, a high-stakes cross-border anti-terror mission along the Pakistan border. The mission underscored the critical need for real-time, pre-emptive intelligence.
“We must detect, identify and track potential threats not when they approach our borders, but when they are still in their staging areas,” said Air Marshal Ashutosh Dixit, Chief of Integrated Defence Staff.
This reflects a strategic shift—from reactive to proactive intelligence gathering. The goal: monitor troop movements, terror camps, and missile deployments well before they pose a direct threat.
Satellite Details and Timeline
- Total Satellites: 52
- ISRO’s Share: 21 satellites (launched via PSLV and SSLV)
- Private Sector Role: 31 satellites developed and deployed by Indian private companies
- First Launch: April 2026
- Full Deployment: By December 2029
- Payload Capabilities: High-resolution optical imaging, Synthetic Aperture Radar (SAR) for day-night, all-weather surveillance
The new satellite constellation will augment and eventually outperform India’s existing space assets like Cartosat-2, RISAT, EMISAT, and GSAT-7A, which currently provide fragmented, multi-purpose surveillance.
Strategic Edge: Keeping Up with China
India’s urgency is partly driven by China’s military-space dominance:
- China’s People’s Liberation Army Strategic Support Force (PLASSF) oversees cyber, electronic, and space warfare.
- China operates over 250–300 military or dual-use satellites, including Yaogan and Gaofen series.
- China demonstrated ASAT (anti-satellite) capabilities as early as 2007.
- The U.S. DoD reports China adds dozens of ISR satellites annually.
In contrast, India currently operates fewer than 20 dedicated defence satellites. The new 52-satellite program will more than double India’s current space intelligence footprint.
The Indian Ocean: The New Frontier
The SBS Phase 3 will also monitor the Indian Ocean Region (IOR), a key geopolitical arena:
- Track PLAN warships and Chinese submarines.
- Monitor suspicious or dual-use merchant vessels.
- Curb illegal fishing, smuggling, and piracy in Indian waters.
China’s String of Pearls—a strategic chain of ports and bases from Gwadar to Sri Lanka to the Maldives—adds urgency to the maritime surveillance push.
Private Sector Power: ISRO’s Strategic Collaboration
This project also marks a major public-private partnership milestone:
- ISRO will transfer SSLV technology to private firms for agile deployment.
- Companies like L&T, Tata Advanced Systems, Pixxel, and Dhruva Space are expected to be involved.
- This follows global models like SpaceX and Planet Labs, where private firms support defence efforts.
Challenges and Next Steps
Experts warn that satellites alone won’t suffice. India must develop:
- AI-enabled analytics to process imagery into actionable intelligence.
- Robust ground stations for real-time data relay.
- Cybersecurity architecture to protect satellite networks.
- Redundancy planning and ASAT defence measures for resilience in wartime.
What This Means for India’s Future
The 52-satellite initiative isn’t just about catching up — it’s about staying ahead. As conflicts extend from land and sea to cyberspace and outer space, India’s new surveillance constellation could give it the first-mover advantage in detecting and deterring threats.
For India’s military, this means:
- Shorter response times
- Accurate targeting
- Fewer intelligence blind spots
For adversaries, it means being watched—always, whether at border bases, missile staging areas, or across vast oceanic trade routes.
