About HAL:-

Hindustan Aeronautics Limited (HAL) came into existence on 1st October 1964.  The Company was formed by the merger of Hindustan Aircraft Limited with Aeronautics India Limited and Aircraft Manufacturing Depot, Kanpur.

The Company traces its roots to the pioneering efforts of an industrialist with extraordinary vision, the late Seth Walchand Hirachand, who set up Hindustan Aircraft Limited at Bangalore in association with the erstwhile princely State of Mysore in December 1940. The Government of India became a shareholder in March 1941 and took over the Management in 1942.

Today, HAL has 19 Production Units and 10 Research and Design Centres in 8 locations in India. The Company has an impressive product track record - 15 types of aircrafts/Helicopters manufactured with in-house R & D and 14 types produced under license. HAL has manufactured  over 3646 Aircrafts/Helicopters , 4096 engines and overhauled over 9447 aircraft and 29886 engines.
