Overview
- ISRO ran the CE20 for 165 seconds at 22 tonnes of thrust on March 10 at the Propulsion Complex in Mahendragiri, Tamil Nadu.
- The test used a Nozzle Protection System and a multi‑element igniter to manage sea‑level risks, and the engine and facility performed as expected.
- The run elevates sea‑level testing from earlier 19‑tonne firings, qualifying operation at the higher thrust level.
- The specific engine has completed a record 20 hot tests, demonstrating ignition margins, indigenous turbopump bearings and sensors, and in‑flight restart capability.
- The outcome supports flight acceptance of an uprated C32 upper stage intended to increase LVM3 lift capacity for upcoming missions, including crewed plans under Gaganyaan.
