India is no longer just a land-based defense power—it's rapidly emerging as a formidable force in space. With its latest space surveillance mission, ISRO is about to launch a historic military advancement that has already caused alarm in Pakistan. A fleet of 52 spy satellites is being prepared, marking the beginning of one of India’s most ambitious and game-changing defense strategies post-Operation Sindoor.
The Origin: Lessons from Operation Sindoor
In May 2025, a high-intensity conflict unfolded between India and Pakistan in the border regions. Named Operation Sindoor, the mission revealed a critical insight—modern warfare is increasingly won by those who have persistent and uninterrupted eyes in space. Although India effectively used ISRO's Cartosat satellites and some commercial foreign satellites to monitor enemy movements, delays in data and limited coverage became a challenge.
That was the turning point. Under the leadership of Prime Minister Narendra Modi, the Cabinet Committee on Security gave a green signal in October 2024 to launch Space-Based Surveillance Phase 3 (SBS-3)—a ₹2,968 crore initiative to build and deploy 52 surveillance satellites.
The Mission: SBS-3 Explained
Of the 52 satellites, 21 will be developed by ISRO, while 31 will be built by three private Indian companies. These firms—names withheld for security reasons—already possess experience in satellite manufacturing and AI-based image processing. This collaboration represents the true spirit of Make in India, for India, against enemies.
These satellites will be deployed in both Low Earth Orbit (LEO) and Geostationary Orbit (GEO), covering altitudes from Earth’s surface to over 36,000 km. This ensures that no enemy, especially in hostile regions like Pakistan and China, can escape India's gaze.
Persistent Surveillance: A Game Changer
Until now, India’s satellites had long revisit times, meaning they could observe a particular area only after several hours. But with the launch of these 52 satellites, the revisit time will shrink to just a few minutes. This improvement enables live tracking of troop movements and other tactical decisions on enemy soil.
This will boost the efficiency of the OODA loop (Observe, Orient, Decide, Act)—a decision-making cycle crucial to military operations. Faster inputs lead to faster and more accurate actions, significantly enhancing the Indian Army’s combat capabilities.
Private Sector Joins the Battlefield
For the first time, India’s private aerospace sector is playing a central role in national defense. The defense ministry has issued direct orders to three Indian companies to manufacture and launch satellites quickly. These firms are equipped with cutting-edge manufacturing facilities and specialize in AI-enhanced satellite imaging—bringing speed, precision, and innovation to India’s military space ambitions.
Dual Surveillance Network: Sky and Stratosphere
The Indian Air Force is also enhancing its aerial surveillance by demanding three High Altitude Platform Systems (HAPS)—drone-like aircraft capable of hovering in the stratosphere for weeks. Flying at around 20 km above sea level, these HAPS will monitor the Pakistan border without needing to descend, functioning as pseudo-satellites. In combination with space satellites, they will form a dual-layered surveillance network that leaves no blind spots.
The Bigger Picture: Competing with China
As of 2024, China has over 1,000 military satellites, including 360 dedicated to surveillance. Their PLA Aerospace Force is already engaging in "satellite dogfights"—the ability to disable enemy satellites in space. While this represents a significant threat, India’s 52-satellite program is the first step toward closing this gap.
These satellites won’t be limited to surveillance. The Indian defense establishment is also developing a military space doctrine that will include anti-satellite strategies and counter-space capabilities. This is a clear signal that India intends to secure not just land, air, and sea—but also space.
The Future: Space Is the First Battlefield
According to Air Marshal Ashutosh Dixit, space is no longer the final frontier—it is now the first battlefield. India's space assets must detect threats while they are still at enemy bases, long before they reach the Indian border. This demands real-time, high-resolution, round-the-clock surveillance from above.
With this new initiative, India is taking responsibility for its defense not just on Earth but in orbit. ISRO’s powerful 52-satellite army ensures that any hostile activity will be detected and neutralized before it poses a threat. And for adversaries like Pakistan, which lack the resources, technology, and political stability, this satellite army is a nightmare becoming reality.
India’s defense strategy is evolving rapidly, and the battlefield has officially expanded into space. With the combination of government-led programs and private sector innovation, ISRO's 52 spy satellites are not just an answer to today’s challenges—they are a signal to the world that India is ready to lead in space-based defense.
