The HAL Tejas (Hindi pronunciation: [t̪eːdʒəs]) is a lightweight multirole fighterdeveloped by India. It is a tailless,[N 1] 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",[4][N 2] meaning "Radiance" by then Prime Minister Atal Bihari Vajpayee.[5]
The Tejas has a pure delta wing configuration, with no tailplanes or foreplanes, 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.
The Tejas is the second supersonic fighter developed indigenously by Hindustan Aeronautics Limited after the HAL Marut. The Indian Air Force (IAF) is reported to have a requirement for 200 single-seat and 20 two-seat conversion trainers, while the Indian Navy may order up to 40 single-seaters to replace its Sea Harrier FRS.51 and Harrier T.60.[6] The Tejas was cleared in January 2011 for use by Indian Air Force pilots. It is to reach final operational clearance in 2013.
