ABOUT
The HAL Tejas is a multi-role light fighter under development 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",[N 2] meaning "Radiance" 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 manoeuvrable, and is the smallest and lightest in its class of contemporary combat aircraft.
The Tejas is the second supersonic fighter developed indigenously by Hindustan Aeronautics Limited (HAL) after the HAL Marut. The Indian Air Force (IAF) was reported to have a requirement for 200 single-seat and 20 two-seat conversion trainers, while the Indian Navy might order up to 40 single-seaters to replace its Sea Harrier FRS.51 and Harrier T.60. The Tejas was cleared in January 2011 for use by Indian Air Force pilots. It received the second of three levels of operational clearance on 20 December 2013.
