ISRO is set to make history today by launching its heaviest-ever communication satellite, CMS-03, aboard the powerful LVM3-M5 ‘Bahubali’ rocket from Sriharikota.
Key Takeaways
- CMS-03, at 4,410 kg, is India’s heaviest communication satellite launched from Indian soil.
- The LVM3-M5 ‘Bahubali’ rocket will lift off at 5:26 PM IST on November 2, 2025.
- The satellite will enhance maritime communications for the Indian Navy across wide oceanic regions.
About the CMS-03 Satellite
Weighing approximately 4,410 kg, the CMS-03 represents a significant milestone for India’s space capabilities. This multi-band communication satellite is specifically designed to provide coverage over extensive oceanic zones surrounding the Indian subcontinent.
Strategically, CMS-03 will strengthen communication networks for naval, air, and sea-based operations. Its primary role involves connecting warships, aircraft, and remote maritime assets with reliable, uninterrupted connectivity.
The LVM3-M5 ‘Bahubali’ Rocket
The launch vehicle powering this mission is ISRO’s heavy-lift LVM3 (Launch Vehicle Mark-3), also known as GSLV Mk III. The rocket features a robust three-stage configuration:
- Two S200 solid rocket boosters for initial liftoff thrust
- A liquid-propellant core stage (L110) with Vikas engines
- A cryogenic upper stage (C25) using indigenous technology
This architecture enables ISRO to launch 4,000 kg-class satellites into Geosynchronous Transfer Orbit and up to 8,000 kg into Low Earth Orbit. The LVM3 boasts a perfect success record, including the celebrated Chandrayaan-3 lunar mission in 2023.
