About LVM-3

LVM-3, also known as GSLV Mk III or “Bahubali,” is a heavy-lift launch vehicle developed by ISRO. It is specifically engineered to carry large satellites into space and support human spaceflight missions.

The rocket stands approximately 43.43 meters tall and has a lift-off mass of around 640 tonnes, making it India’s heaviest launch vehicle. It can transport up to 4 tonnes to Geostationary Transfer Orbit (GTO) and 10 tonnes to Low Earth Orbit (LEO).

LVM-3 is a three-stage rocket that includes two solid rocket boosters (S200), a liquid core stage (L110), and a cryogenic upper stage (C25). It has been utilized for launching heavier communication satellites, interplanetary missions, and India’s Gaganyaan human spaceflight project. The rocket had its first successful experimental flight in December 2014 and is renowned for its reliability and capacity to handle heavy payloads.
