HAL working on Mk-1A configuration
If the present development and capacity enhancement plans go as scheduled, the Indian Air Force will have 123 Tejas jets, indigenously made light combat aircraft, on its fleet by 2024-25.

Mk-1A configuration
The configuration with specific improvements is sought by the IAF, the advanced electronically scanned array (AESA) radar and self-protection jammer (SPJ).

What is Tejas?
The HAL Tejas is an Indian single-seat, single-jet engine, multi-role light weight fighter designed by the Aeronautical Development Agency and Hindustan Aeronautics Limited for the Indian Air Force and Navy.

What is advanced electronically scanned array (AESA)?
An active electronically scanned array ( AESA ), is a type of phased array antenna, that is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

What is self-protection jammer (SPJ)?
An electronic system carried by an aircraft to prevent detection by enemy radar, by both emitting signals that obscure radar returns and disguising the jamming signal itself.

Importance for IAF
The IAF is in urgent need of new fighters and the LCAs will replace the MiG fighters which are being phased out.
