ISRO says the cryogenic engine designated for its next GSLV flight successfully completed a flight acceptance test on 5 November 2026 at Mahendragiri. Both the main engine and gas generator ignited as expected, and the 200-second test met performance expectations. The engine is intended for the GSLV-F19 mission carrying the NVS-04 navigation satellite.
