About the Launch Vehicle

LVM 3 is a heavy launch capability launcher being developed by ISRO. It will allow India to achieve complete self reliance in launching satellites as it will be capable of placing 4 tonne class Geosynchronous satellites into orbit. The LVM3 will have an India built cryogenic stage with higher capacity than GSLV. The first experimental flight of LVM3, the LVM3-X/CARE mission lifted off from Sriharikota on December 18, 2014 and successfully tested the atmospheric phase of flight. Crew module Atmospheric Reentry Experiment was also carried out in this flight. The module reentered, deployed its parachutes as planned and splashed down in the Bay of Bengal.

Vehicle Specifications

Height: 43.43 m
Vehicle Diameter: 4.0 m
Heat Shield Diameter: 5.0 m
Number of Stages: 3
Lift Off Mass: 640 tonnes
The payload for LVM3 is accommodated in the composite payload fairing which has a diameter of 5 m, and has a volume of 110 m3. For CARE, the crew module was positioned on the payload adaptor in an inverted position to ensure favourable reentry attitude.
C25 stage is newly developed, totally indigenous upper stage of LVM3. This is the terminal stage of the vehicle loaded with 27 tons of propellants (LOX & LH2) and powered by a 186 kN (nominal) thrust engine (CE20) working on gas generator cycle with independent turbines running LH2 & LOX pumps. The stage has an overall diameter of 4 m and length of 13.5 m. Though the configuration of the stage draws experience from CUS stage of GSLV significant functional and operational changes are adopted in C25 stage. A passive C25 stage was used in the LVM3-X flight.
L110 stage is the core stage of LVM3 with twin engine configuration to generate a combined thrust of 1598 kN for 200 sec duration. Powered by two Vikas engines, the core stage of LVM3 will be the powerhouse of the launch vehicle as it will propel the vehicle through the atmospheric phase of its flight.
The first stage of LVM3 is powered by two strap-on solid boosters with 207 tons of propellant loading and delivering a combined initial thrust of 950 tons. S200 is the biggest solid booster developed by ISRO and is the fourth largest in the world.


Payload to GTO: 4,000 kg

LVM3 will be capable of placing the 4 tonne class satellites of the GSAT series into Geosynchronous Transfer Orbits.

Payload to LEO: 8,000 kg

The powerful cryogenic stage of LVM3 enables it to place heavy payloads into Low Earth Orbits of 600 km altitude.

Cryogenic Upper Stage : C25

The C25 is powered by CE-20, India's largest cryogenic engine, designed and developed by the Liquid Propulsion Systems Centre of ISRO located at Thiruvananthapuram.

Cryo Stage Height: 13.5 m
