ISRO successfully conducted the eighth hot test of the Semi-Cryogenic Engine Power Head Test Article (PHTA) on June 24, 2026, at the ISRO Propulsion Complex (IPRC) in Mahendragiri, Tamil Nadu. During the test, the engine achieved an 88% thrust level of 175 tonnes, exceeding the performance of earlier tests. The engine uses Liquid Oxygen (LOX) and Isrosene as cleaner and more efficient propellants. The test is an important milestone in the development of the indigenous SE2000 semi-cryogenic engine, which is intended to replace the L110 core stage of the LVM3 launch vehicle, thereby enhancing payload capacity and mission efficiency.
