New Delhi: The Indian Space Research Organisation (ISRO) successfully completed the flight acceptance hot test of the CE20 cryogenic engine that will power the upcoming LVM3-M7 mission. The test confirmed the engine’s readiness for flight and supports ISRO’s plans to enhance the payload capability of its heaviest operational launch vehicle.
The successful test was conducted at the ISRO Propulsion Complex in Mahendragiri, Tamil Nadu, and represents an important step toward future heavy-lift launches and the Gaganyaan human spaceflight program.
Details of ISRO CE20 Cryogenic Engine Hot Test
ISRO carried out the flight acceptance hot test of the CE20 cryogenic engine designated for the seventh operational mission of the LVM3 launch vehicle, known as LVM3-M7. The test validated the engine’s performance before its integration into the launch vehicle.

The CE20 engine powers the upper cryogenic stage of the LVM3 rocket and plays a critical role in placing heavy satellites into orbit. The successful acceptance test confirms that the engine is ready for upcoming mission requirements.
ISRO CE20 Cryogenic Engine Hot Test Conducted At Mahendragiri Facility
The hot test was performed at the Main Engine and Stage Test Facility located at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu.
This facility is one of ISRO’s most important centers for testing advanced propulsion systems and rocket engines before launch missions.
Why The 22-Ton Thrust Test Is Important
The CE20 engine was tested at an upgraded thrust level of 22 tons. This higher thrust capability is part of ISRO’s efforts to improve the performance of future LVM3 missions and increase payload carrying capacity.
Future missions are expected to use the upgraded C32 cryogenic stage, allowing the launch vehicle to carry heavier payloads to orbit. The successful test demonstrates that the engine can reliably operate at this enhanced thrust level.
Nozzle Protection System Played Key Role
ISRO used its newly developed Nozzle Protection System during the acceptance test. This technology allows engineers to perform sea-level testing while simulating conditions normally experienced at high altitudes. The system reduces testing complexity and improves efficiency.
ISRO CE20 Cryogenic Engine Hot Test: Major Boost For Gaganyaan Program
One of the most significant outcomes of the test was the successful demonstration of the LOX Tank Pressurisation Module.
This module is being developed for the upgraded C32 stage and is also important for future Gaganyaan missions. Its successful performance strengthens confidence in systems that may support India’s human spaceflight ambitions.
Human Spaceflight Requires High Reliability
Human spaceflight missions demand extremely reliable propulsion systems. The successful validation of critical components during the CE20 engine test demonstrates ISRO’s continued progress toward ensuring the safety and reliability required for crewed missions.
Ce20 Engine’s Proven Track Record
The CE20 cryogenic engine has already powered several important Indian space missions. The engine family has contributed to major LVM3 launches, including missions supporting Chandrayaan programs and commercial satellite deployments. Its consistent performance has made it one of ISRO’s most reliable propulsion systems.
Backbone Of India’s Heavy-Lift Launch Capability
LVM3 is India’s most powerful operational launch vehicle. The rocket is designed to launch heavy communication satellites, deep-space missions, commercial payloads, and future human spaceflight missions. The CE20 engine serves as the backbone of its upper-stage propulsion system.
