Introduction
→ The ISRO developed the three-stage heavy lift launch vehicle known as the Geosynchronous Satellite Launch Vehicle, or GSLV (Launch Vehicle Mark III).
→ The heaviest satellites that can be carried by this launch vehicle include.
→ The LVM, also known as the GSLV Mk III, was designed with specific objectives in mind.
→ The page below details these aims as well as the LVM's successful launches, payload capacity, and engines.

GSLV Mk III or LVM Objectives
→ LVM Mk-III has more thrust than the Polar Satellite Launch Vehicle (PSLV), ISRO's most successful launch vehicle.
→ The following is a list of GSLV Mk III's development goals.
- to orbit more substantial communication satellites
- to launch larger, more versatile spacecraft into orbit
- Travel between planets in the future
- to begin the launch of impending crewed missions, or space travel.

(1). GTO payload: 4,000 kg
→ The GSAT series' 4-tonne class satellites can be launched into geosynchronous transfer orbits by LVM3.
(2). LEO (Low Earth Orbit) payload: 8,000 kg
→ LVM3's potent cryogenic stage makes it possible to launch large payloads into Low Earth Orbits with an altitude of 600 km.
(3). Upper Cryogenic Stage: C25
→ The largest cryogenic engine in India, the CE-20, which was created and built by the Liquid Propulsion Systems Centre, powers the C25.
- Cryo Stage Height: 13.5 m
- Cryo Stage Diameter: 4.0 m
- Engine: CE-20
- Fuel: 28 tonnes of LOX + LH2
(4). Boosters for solid rockets: S200
→ The massive amount of thrust needed for takeoff is provided by two S200 solid rocket boosters, which are used by LVM3.
→ The Vikram Sarabhai Space Centre was where the S200 was created.
- Booster Height: 25 m
- Booster Diameter: 3.2 m
- Fuel: 205 tonnes of HTPB (nominal)
(5). Core Stage: Liquid Stage L110
- Stage Height: 21 m
- Stage Diameter: 4.0 m
- Engine: 2 x Vikas
- Fuel: 115 tonnes of UDMH + H2O
Launch of LVM Mk III
→ The GSLV Mk III has been successfully launched numerous times so far.
→ Below is a list of the items.
- Launched in December 2014, CARE stands for Crew Module Atmospheric Re-entry Mission.
- The GSAT-19 Mission was started in June 2017.
- The GSAT-29 Mission was launched in November 2018.
- It was a moon expedition called Chandrayaan 2. 2019 saw its premiere.
- OneWeb: In October 2022, 36 OneWeb satellites were successfully launched by the first LVM3 commercial launch.
- OneWeb: OneWeb's second official commercial launch. most substantial load ever launched by an LVM3 and ISRO. The project got underway in March 2023.
