India is eyeing to speed up the launch of its 52 defence surveillance satellites to enhance space-based observation, particularly on borders with China, Pakistan and in the Indian Ocean Region, media reports said.

The project is estimated to be Rs 26,968 crore.

Under Phase 3 of the Space-Based Surveillance (SBS) initiative, the Indian Space Research Organisation (ISRO) will launch 21 satellites, while three private firms will develop and deploy the remaining 31, reported India Today.

According to reports, the first satellite in this constellation is scheduled to be launched in April 2026.

The constellation will provide high-resolution imagery and faster revisit times to assist India's Army, Navy and Air Force in tracking enemy movements deep within adversary territory, the Indian news channel reported.

The project reportedly assumes significance following India's recent launch of Operation Sindoor against terror camps in Pakistan and PoK after terrorists attacked and killed 26 people in Pahalgam town in Jammu and Kashmir on April 22.
