The LCA-Tejas is an indigenous single-seat and single-jet engine light fighter made by Hindustan Aeronautics Limited or HAL for the military primarily for the Air Force. It has a tailless and compound delta wing design which is very steerable. It originated from the Light Combat Aircraft programme started in the 1980a. It was initiated to substitute the older MiG-21 fighters. The LCA was rechristened ‘Tejas’ meaning radiant in the Sanskrit language by the then PM Vajpayee.

The recommendations of the Aeronautics Committee in 1969 that HAL should be allotted the task of designing and developing a fighter craft around an established engine, was accepted by the GOI. Tejas is the second supersonic fighter aircraft to be developed by HAL, the first one being the HF-24 Marut.
