ISRO completes CE20 flight-acceptance hot test for LVM3 M7

ISRO has carried out a flight-acceptance hot test of the CE20 cryogenic engine for the LVM3 M7 mission. The agency said the test was successful and that it achieved all planned objectives.

The work was conducted at the Main Engine & stage Test facility as part of the acceptance process used for cryogenic engines before flight.

ISRO said the CE20 cryogenic engine completed flight-acceptance hot testing for LVM3 M7, and described the result as successful.

According to the verified facts, the CE20 engine met all test objectives and is identified here with a value of 22 t.

The flight-acceptance hot test was conducted at the Main Engine & stage Test facility. The facts also state that cryogenic engines undergo hot testing for flight acceptance.

ISRO also successfully demonstrated a LOX Tank Pressurization Module during this work.

A Nozzle Protection System was developed and validated, and the facts say it reduced time and effort.

LVM-M7 is described in the verified facts as the seventh operational mission of the LVM3 launch vehicle.

For readers tracking lunar-sector launch capability, the update shows ISRO moving a cryogenic upper-stage engine through flight acceptance for an identified LVM3 mission.

The successful demonstration of associated hardware, including the LOX Tank Pressurization Module and the validated Nozzle Protection System, indicates supporting propulsion elements were part of the reported test campaign.

ISRO is the Indian space agency.

The verified facts list the LVM3 M7 mission for 2026-Q4.
