LVM3: ISRO's Heaviest Rocket, Flight by Flight
LVM3, first called GSLV Mk III and nicknamed "Bahubali", is ISRO's most powerful rocket: two giant solid boosters, a liquid core and a CE-20 cryogenic upper stage, 640 tonnes at lift-off. It has launched both Chandrayaan landers, India's first commercial mega-constellation flights and the heaviest payload ever sent up from Indian soil — without a single failure so far.
LVM3 has flown 9 times, every one a success. Its next big job is carrying India's first astronauts on Gaganyaan.
9 milestones from 2014 to 2025: 9 successes, 0 failures, 0 partial successes and 0 other milestones.

2025 · Heaviest yet
Two flights in two months pushed LVM3 to new records — first to geosynchronous transfer orbit, then to low Earth orbit.
LVM3-M6 · BlueBird Block-2
24 Dec 2025 · LVM3 · Success · Heaviest payload launched from India
LVM3 placed AST SpaceMobile's 6,100 kg BlueBird Block-2 in a roughly 520 km orbit — its first dedicated launch for a US customer and the heaviest payload ever launched from India.
LVM3-M5 · CMS-03
2 Nov 2025 · LVM3 · Success
LVM3 launched CMS-03 (GSAT-7R), a 4,400 kg Navy communication satellite — the heaviest satellite India had sent towards geosynchronous orbit. The flight also tested the cryogenic stage further after separation.
2022–2023 · Going commercial
When OneWeb lost access to Russian rockets in 2022, it turned to ISRO. Two LVM3 flights carrying 36 satellites each made the rocket a commercial launcher — renamed LVM3 along the way.
LVM3-M4 · Chandrayaan-3
14 Jul 2023 · LVM3 · Success · Launched India's Moon landing
LVM3 sent Chandrayaan-3 on the journey that ended with the first landing near the lunar south pole on 23 August 2023.

LVM3-M3 · OneWeb India-2
26 Mar 2023 · LVM3 · Success
A second batch of 36 OneWeb satellites completed the company's first-generation constellation.
LVM3-M2 · OneWeb India-1
23 Oct 2022 · LVM3 · Success
LVM3's first commercial flight carried 36 OneWeb internet satellites, about 5.8 tonnes, to low Earth orbit — the first time it flew to LEO rather than a transfer orbit.
2014–2019 · Test flights to the Moon
LVM3 was built to launch four-tonne communication satellites without depending on foreign rockets. Its first flight was a suborbital test; by its fourth it was sending India's second Moon mission on its way.
LVM3-M1 · Chandrayaan-2
22 Jul 2019 · LVM3 · Success
LVM3's first operational flight placed Chandrayaan-2 into a higher-than-planned Earth orbit, saving the spacecraft fuel. The rocket's part went perfectly; the Vikram lander was lost during its Moon landing attempt seven weeks later.
Chandrayaan-2 story
LVM3-D2 · GSAT-29
14 Nov 2018 · LVM3 · Success
The second developmental flight launched the GSAT-29 high-throughput communication satellite, completing LVM3's qualification.
LVM3-D1 · First orbital flight
5 Jun 2017 · LVM3 · Success · First flight of the CE-20 engine
The first full LVM3, with its new CE-20 cryogenic engine, placed the 3,136 kg GSAT-19 in geosynchronous transfer orbit — the heaviest satellite launched from India at the time.
LVM3-X / CARE · Suborbital test
18 Dec 2014 · LVM3 · Success
The first LVM3 flew with live solid boosters and core stage but a dummy cryogenic stage, reaching 126 km. It released CARE, a prototype crew capsule, which re-entered and splashed down in the Bay of Bengal near the Andaman and Nicobar Islands.

Key facts for exams
- LVM3 = Launch Vehicle Mark-3, formerly GSLV Mk III; nicknamed "Bahubali".

- Height 43.5 m, diameter 4 m, lift-off mass 640 tonnes (ISRO figures).
- Capacity: 4,000 kg to GTO, 8,000 kg to a 600 km LEO (ISRO figures).

- Launched Chandrayaan-2 (2019) and Chandrayaan-3 (2023).
- LVM3-M6 (24 December 2025) carried the 6,100 kg BlueBird Block-2 — the heaviest payload launched from India.
- A human-rated version, HLVM3, is being prepared for the Gaganyaan crewed missions.
Words used on this page
- Cryogenic engine
- An engine that burns liquid hydrogen (at about −253 °C) and liquid oxygen (about −183 °C). It gets more push per kilogram than other fuels, which upper stages need for heavy satellites — but it is one of the hardest rocket technologies to build.
- Geostationary and geosynchronous orbit
- An orbit about 36,000 km up that takes exactly one day, matching Earth's spin. A geostationary satellite sits over the equator and seems fixed in the sky; a geosynchronous one may drift north and south in a figure-of-eight.
- Geosynchronous transfer orbit (GTO)
- A long oval orbit, low at one end and about 36,000 km at the other. Rockets drop communication satellites here; the satellite then fires its own engine at the high point to circle at that height.
- Low Earth orbit (LEO)
- Orbits from about 160 to 2,000 km above Earth. Satellites here circle the planet in roughly 90 minutes — the ISS, Starlink and most imaging satellites live here.
- Payload
- Whatever a rocket carries — satellites, a spacecraft, experiments. On a spacecraft, "payloads" are its science instruments.
- Re-entry
- Coming back into Earth's atmosphere from space. Friction heats the object to thousands of degrees, so anything meant to survive needs a heat shield.
- Rocket stage
- A section of a rocket with its own engine and fuel. When its fuel runs out it drops away, so the rest of the rocket is lighter and can go faster. PSLV has four stages.
Frequently asked questions
What is the full form of LVM3?
LVM3 stands for Launch Vehicle Mark-3. It was originally called GSLV Mk III and renamed in 2022, partly because it shares little with the GSLV Mk II apart from the name.
Why is LVM3 called Bahubali?
Because it is ISRO's heaviest and most powerful rocket. The nickname, borrowed from the blockbuster film, became popular with the media around its first orbital flight in 2017.
Has LVM3 ever failed?
No. All of its flights so far — from the 2014 suborbital test to the BlueBird launch in December 2025 — have been successful. Chandrayaan-2's lander was lost in 2019, but that happened at the Moon, weeks after LVM3 had done its job.
Will LVM3 carry astronauts?
Yes. A human-rated version, HLVM3, with extra safety margins, redundant systems and a crew escape system, is being prepared to launch ISRO's Gaganyaan missions.
