Brief History

Aerospace Division BangaloreWelcome to the Aerospace Division of Hindustan Aeronautics Limited.

India's growing involvement in space exploration is reflected in the establishment of a world class manufacturing base for space worthy hardware. The Aerospace Division of HAL so established is today dedicated to the manufacture of hardware for India's growing space programs. Hindustan Aeronautics Ltd's participation in space programs started as early as 1972 and formed into a full fledged dedicated facility thereafter.

The Division has the technical expertise to fabricate large size Aluminium Alloy riveted structures, welded propellant tanks and water tanks. Currently under production are the Light Alloy Structures for the Polar Satellite Launch Vehicle (PSLV), Geo-stationary Launch Vehicle (GSLV MkII), Indian Remote Sensing Satellite (IRS), Indian National Satellite (INSAT) and the structures & welded tanks for the Cryogenic upper stage of GSLV MkII. The Division has taken up full equipping & integration of the strap on L – 40 stage for GSLV MkII and also manufacture of all riveted structures & welded tankages for a larger GSLV MK III vehicle with enhanced capabilities.

The Division's strength lies in a team of highly motivated professionals. Out of a total strength of 615, 302 personnel are involved in direct production. As many as 40 qualified and trained personnel constitute our quality assurance team.

The Division has been accredited with AS 9100 and ISO 14001:2004 certified by KEMA of Netherlands.
