HAL Tejas an Indian single-seat, single-jet engine, multi-role light fighter developed by Hindustan Aeronautics Limited. It is a tailless, compound delta wing design powered by a single engine. It came from the Light Combat Aircraft (LCA) programme, which began in the 1980s to replace India’s ageing MiG-21 fighters. Later, the LCA was officially named “Tejas”,[N 2] meaning “Radiant” by the then Prime Minister Atal Bihari Vajpayee.
Tejas has a pure double delta wing configuration (wing root leading edge sweep 50°, outer wing leading edge sweep 62.5° and trailing edge forward sweep 4°), with no tailplanes or canard, and a single dorsal fin.
It integrates technologies such as relaxed static stability, fly-by-wire flight control system, multi-mode radar, integrated digital avionics system, composite material structures, and a flat rated engine. It is supersonic and highly maneuverable, and is the smallest and lightest in its class of contemporary combat aircraft. Via: Wikipedia
