Launch Vehicle Mark-3

The Launch Vehicle Mark-3 or LVM3 (previously referred as the GSLV Mk III) is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO). Primarily designed to launch communication satellites into geostationary orbit, it is also due to launch crewed missions under the Indian Human Spaceflight Programme. LVM3 has a higher payload capacity than its predecessor, GSLV.

The CE-20 is a cryogenic rocket engine developed by the Liquid Propulsion Systems Centre (LPSC), a subsidiary of ISRO. It has been developed to power the upper stage of the LVM3. It is the first Indian cryogenic engine to feature a gas-generator cycle. The high thrust cryogenic engine is the most powerful upper stage cryogenic engine in operational service.

The SE-2000 (formerly known as SCE-200, also referred as Semi-Cryogenic Engine-2000) is a 2 MN thrust class liquid rocket engine, being developed to power ISRO's existing LVM3 and upcoming heavy and super heavy-lift launch vehicles. It is being developed by the Liquid Propulsion Systems Centre (LPSC) of ISRO, and is expected to have first flight in 2020s.
