ISRO to launch India's biggest military satellite on November 2
ISRO is about to launch its biggest-ever communication satellite, CMS-03 (GSAT-7R), for the Indian Navy on November 2, 2025.
The 4,400kg satellite—costing ₹1,589 crore—will lift off from Sriharikota using the LVM3-M5 rocket and will take over from the decade-old GSAT-7.
CMS-03 will connect naval assets up to 2,000km from coast
CMS-03 will give secure voice, video, and data links to naval ships, submarines, and aircraft up to 2,000km from India's coast.
With upgraded tech across multiple frequency bands, it'll help the Navy stay connected and expand its reach across the seas.
Major step toward self-reliant naval communications
This is ISRO's heaviest payload yet for Geosynchronous Transfer Orbit—and their first LVM3 mission since Chandrayaan-3.
The satellite and rocket are already prepped on the launch pad as of late October.
It's a major step in making India's naval communications more self-reliant.
Boost to India's networked warfare at sea
CMS-03 will seriously boost India's networked warfare abilities at sea by making command operations stronger and more resilient.
Plus, with ISRO's heavy-lift LVM3 successfully used for Chandrayaan-3, launching big military satellites like CMS-03 demonstrates India's growing capability in this area.
