New Delhi: ISRO LVM3-M7 C32 stage has officially been confirmed for the next LVM3 mission. The Indian Space Research Organisation (ISRO) announced that the upcoming LVM3-M7 mission will fly with the upgraded C32 cryogenic upper stage instead of the older C25 stage. This is an important step in improving India’s heavy-lift launch vehicle and increasing its payload capability for future space missions.
ISRO Confirms C32 Cryogenic Stage for LVM3-M7
According to ISRO, the next LVM3-M7 mission will use the newly upgraded C32 cryogenic upper stage. This also means that the LVM3-M6 mission, launched in December 2025, was the final flight to use the C25 cryogenic stage. The change marks the beginning of a new generation of upper-stage technology for India’s heaviest operational rocket.

What is the C32 Cryogenic Stage
The C32 is an improved version of the C25 cryogenic upper stage. Some of the major upgrades include:
- Increased Hydrolox propellant capacity from 28 tonnes to 32 tonnes.
- Upgraded CE-20 cryogenic engine with around 22 tonnes of thrust.
- Better overall performance and improved payload-carrying capability.
- Designed to support future high-performance LVM3 missions.
What is the Importance of C32 Cryogenic Stage
The additional propellant and more powerful engine will allow the LVM3 rocket to carry heavier satellites and mission payloads. The upgraded stage is also an important technology for India’s future space ambitions, including advanced commercial launches and upcoming human spaceflight-related missions under the Gaganyaan programme.
Recent Milestone Before the Mission
Just before confirming the C32 stage, ISRO successfully completed the Flight Acceptance Test (FAT) of the upgraded CE-20 cryogenic engine for the LVM3-M7 mission. The successful engine test confirmed that the propulsion system is ready for flight and cleared another major milestone before launch.
