LCA Tejas

  • The Tejas is an Indian single-engine, fourth-generation, multirole light fighter aircraft.
  • It is designed by the Aeronautical Development Agency (ADA) in collaboration with the Aircraft Research and Design Centre (ARDC) of Hindustan Aeronautics Limited (HAL).
  • It came from the Light Combat Aircraft (LCA) programme, which began in the 1980s to replace India’s ageing MiG-21 fighters.
  • The indigenous content of the Tejas was 59.7% by value and 75.5% by a number of lines replaceable units.

Which are the procured variants?

  • Light Combat Aircraft Mk-1A variant is an indigenously designed, developed and manufactured state-of-the-art modern 4+ generation fighter aircraft.
  • It is the first “Buy (Indian-Indigenously Designed, Developed and Manufactured)” category procurement of combat aircraft.


  • Tejas enable IAF to handle repairs or servicing at their base depot so that the turnaround time would get reduced for mission-critical systems.
  • This would enable IAF to sustain the fleet more efficiently and effectively due to the availability of repair infrastructure at respective bases.
  • It will give a further push to Atmanirbhar Bharat initiative and boost indigenization of defence production and the defence industry in the country.
