ISRO hot tests semi-cryogenic engine
Analysis based on 11 articles · First reported Jun 27, 2026 · Last updated Jun 27, 2026
The successful hot test by the India — ISRO (ISRO) is a positive development for the aerospace industry, particularly for companies involved in space launch services and satellite technology. The upgrade to the LVM3 launch vehicle is expected to increase payload capacity, potentially leading to more competitive launch costs and increased demand for related services.
The India — ISRO (ISRO) successfully conducted a hot test of its Semi-Cryogenic Engine Power Head Test Article (PHTA) at a thrust level of 175 tonnes (88% of its full capacity) at the India — ISRO Propulsion Complex in Mahendragiri, Tamil Nadu, on June 24, 2026. This eighth test in the series demonstrated steady-state operation at higher thrust levels and successful performance of main turbopumps. This milestone is crucial for the indigenous development of the SE2000 engine, which will power the Semi-Cryogenic Propulsion Stage (SC120). This stage is intended to replace the current L110 core stage of the LVM3 launch vehicle, significantly enhancing its payload capacity and operational efficiency. The new system uses cleaner propellants, Liquid Oxygen (LOX) and purified Kerosene (isrosene), and is a major step towards India's future deep-space and human spaceflight missions.
