ISRO Successfully Tests CE20 Cryogenic Engine, Boosting LVM3 Rocket Capability
Context:
Recently, the Indian Space Research Organisation (ISRO) successfully conducted a sea-level hot test of the CE20 cryogenic engine at the ISRO Propulsion Complex, Mahendragiri (Tamil Nadu). The engine operated for 165 seconds and generated about 22 tonnes of thrust, demonstrating improved capability for India’s heavy-lift rockets.
About the CE20 Cryogenic Engine:
-
-
- CE20 is India’s most powerful indigenous cryogenic rocket engine.
- It powers the upper cryogenic stage of the LVM3 launch vehicle (formerly GSLV Mk-III).
- The engine uses liquid hydrogen and liquid oxygen as propellants.
- It provides the final thrust required to place satellites or spacecraft into orbit.
- CE20 is India’s most powerful indigenous cryogenic rocket engine.
-
Importance of the Test:
-
-
- Enhancing LVM3 Rocket Capability: The upgraded engine will improve the payload capacity of the LVM3 heavy-lift rocket, enabling India to launch heavier satellites and undertake more ambitious deep-space missions.
- Boost to the Gaganyaan Mission: The CE20 engine powers the upper stage of LVM3, the launch vehicle selected for India’s human spaceflight mission, Gaganyaan.
- Strengthening Indigenous Cryogenic Technology: Cryogenic engines are among the most complex rocket technologies. Successful testing strengthens India’s self-reliance in advanced space propulsion systems.
- Enhancing LVM3 Rocket Capability: The upgraded engine will improve the payload capacity of the LVM3 heavy-lift rocket, enabling India to launch heavier satellites and undertake more ambitious deep-space missions.

About the LVM3 Rocket:
The Launch Vehicle Mark-3 (LVM3), earlier known as GSLV Mk-III is India’s heaviest operational launch vehicle, developed by ISRO.
Key features:
-
-
- Three-stage rocket (two solid boosters, liquid core stage, cryogenic upper stage)
- Payload capacity:
- ~10,000 kg to Low Earth Orbit (LEO)
- ~4,200 kg to Geosynchronous Transfer Orbit (GTO)
- ~10,000 kg to Low Earth Orbit (LEO)
- The CE20 engine powers the cryogenic third stage (C25) of the rocket, providing the final thrust required to place satellites or spacecraft into orbit.
- Three-stage rocket (two solid boosters, liquid core stage, cryogenic upper stage)
