tejas – India’s first indigenous fighter aircraft

Tejas-Indian Light Combat Aircraft (LCA) together with its variants, is the smallest and lightest Multi-Role Supersonic Fighter Aircraft of its class. This single engine, Compound-Delta-Wing, Tailless Aircraft is designed and eveloped by ADA with HAL as the principal partner along with DRDO, CSIR, BEL, DGAQA, IAF & IN to meet diverse needs of the Indian Air Force (IAF) and Indian Navy (IN).
Tejas is an amalgamation of contemporary concepts and technologies such as relaxed static-stability, fly-by-wire Flight control, advanced glass cockpit, integrated digital avionics systems and advanced composite materials for the airframe.
Light Combat Aircraft ‘Tejas,’ designed and built in India, joined the Indian Air Force’s squadron called Flying Daggers in Bengaluru.

The HAL Tejas is an Indian single-seat, single-jet engine, multi-role light fighter designed by the Aeronautical Development Agency (ADA) and Hindustan Aeronautics Limited (HAL) for the Indian Air Force and Navy. The aircraft has a tail-less compound delta-wing configuration, which gives it high maneuverablility. It came from the Light Combat Aircraft (LCA) programme, which began in the 1980s to replace India’s ageing MiG-21 fighters. LCA was officially named “Tejas” in 2003, meaning “Radiant” in Sanskrit by the then Prime Minister Shri 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 the smallest and lightest in its class of contemporary supersonic combat aircraft.

The Tejas is the second supersonic fighter developed by Hindustan Aeronautics Limited (HAL) after the HAL HF-24 Marut. As of 2016 the Tejas MK1 was in production for the Indian Air Force (IAF) and the naval version was undergoing flight tests for Indian Navy (IN). The projected requirement for IAF is 200 single-seat fighters and 20 twin-seat trainers, while the IN expects to operate 40 single-seat fighters. The first Tejas IAF unit, No. 45 Squadron IAF Flying Daggers was formed on 1 July 2016 with two aircraft. Initially being stationed at Bangalore, the first squadron will be placed at its home base at Sulur, Tamil Nadu.
