ISRO conducted a successful third hot test of its SE2000 semi-cryogenic engine on May 28, 2025, at the ISRO Propulsion Complex in Mahendragiri. This final test in a three-phase series validated the start-up sequence of the engine, which uses liquid oxygen and kerosene in a staged combustion cycle. The SE2000 will power the upcoming SC120 stage of the LVM3, enhancing its payload capacity significantly. With subsystem validations complete, ISRO now moves toward full engine integration, aiming for a 2027 launch and expanding India’s capabilities in space exploration and global launch services.
