New Delhi, 30 June 2025 — Stung by the insights from Operation Sindoor, India is accelerating its space-based surveillance capability. A constellation of 52 defence satellites will be launched by 2029 to deliver “deep” and “persistent” monitoring across adversary territories, particularly China, Pakistan, and the Indian Ocean Region.
₹26,968 Cr Satellite Network Cleared: ISRO & Private Firms Partner
In October 2023, the Cabinet Committee on Security approved the ₹26,968 crore Space-Based Surveillance Phase‑3 programme. This strategic initiative includes:
- 21 satellites developed and launched by ISRO
- 31 satellites produced by three Indian private space firms
- Constellation deployment aimed by end of 2029, though officials say they are working to compress timelines
The first satellite is scheduled for April 2026, with rapid follow-ups expected.
Military Space Doctrine & HAPS Platforms Enhance Strategy
Concurrently, India is finalising its military space doctrine to align operational protocols with the new space strategy. Moreover, the Indian Air Force plans to deploy three HAPS (high-altitude pseudo-satellites)—stratospheric drones designed for long-endurance ISR (Intelligence, Surveillance & Reconnaissance) missions.

Intelligence Edge: Faster Revisit, Higher Resolution
A confidential source revealed, “The aim of SBS‑3 is to cover much larger areas … with shorter revisit times … and much better resolution.” This will enable continuous observation of hostile military installations “deep within an adversary’s territory.” Integration with the upcoming doctrine is seen as a key enabler of operational synergy.
Operational Imperative: OODA Loop Needs Speed
Relying on both Indian and foreign commercial satellites during Operation Sindoor exposed a critical need for speed. A national security official stated, “We need to shorten our OODA (observe, orient, decide and act) loop. The faster India gets the 52‑satellite constellation up … the better.”
Strategic Shift: From Reactive to Pre-Emptive Posture
This ambitious constellation marks a major shift in India’s defence outlook—from reactive surveillance to pre-emptive, space-enabled intelligence gathering. It will provide real-time satellite data to support India’s armed forces across land, air, and sea, while strengthening deterrence in contested regions.
Why This Matters?
Owning a dedicated 52‑satellite constellation will sharply reduce dependence on dual-use and foreign sources for critical surveillance data.
Integrated Warfare Capability
With HAPS deployment and a unified military space doctrine, India positions space as a core operational domain.
Speed and Precision in Conflict
Improved revisit rates and real-time intelligence delivery will help defence forces respond faster and more decisively to emerging threats.
Strategic Consistency Post-Sindoor
The project cements Operation Sindoor’s lasting impact on India’s defence modernization and space warfare preparation.
