ISRO's engines : Designs , Components & Prototypes.


Larsen & Toubro, JSW, Adani Group and Mahindra are among at least half a dozen home-grown companies or consortiums looking to partner the Indian Space Research Organisation (ISRO) on its heavy-lift launch vehicle mark-3 (LVM3), also known as Bahubali, said people aware of the matter.

These private entities are considering plans to submit expressions of interest (EoIs) for technology transfer from ISRO to manufacture and operate LVM3, the people told ET.

Those interested include an alliance between JSW and startup Ethereal Exploration Guild (EtherealX), a consortium led by Nagpur-based Solar Industries, Bharat Forge and Inox India, the people said.

For Inox India, a maker of cryogenic and propellant-handling equipment, a new aerospace certification would allow it to bid for in-flight equipment, including “propellant tanks, which are part of the rocket,” said chief executive Deepak Acharya on a recent earnings call. He termed the EoI for LVM3 manufacturing as a potential opportunity for Inox.

The selected company or consortium will have 42 months, or two realised launch vehicles, to complete the technology-transfer process. It will initially work with ISRO and IN-SPACe to absorb the technology before establishing the necessary infrastructure to independently manufacture LVM3 systems and subsystems.​
