The LCA Makr1A secretly took its first flight on 20^th May 2022 and there was no footage or pic shared for the same except for the sweet box pic marking its celebration. However, the LCA Mark1A has been spotted now.

Recently, Aviation Wall has shared a video on twitter “Chasing the TEJAS  the raw sound from the cockpit”.

As we already know that IAF has allotted HAL a Tejas Mark 1, numbered SP-25 (series production aircraft number 25), for integrating the modification required for Tejas Mark1A. The SP-25 will act as a test platform for the entire production line of the Mk1A version and will undergo certification tests over coming months. HAL is expected to complete the development trials of the Tejas MK1A by the end of year 2023. As per contract, HAL is required to deliver the first three aircraft in 2024 and 16 aircraft annually for the next five years. HAL is confident of delivering first LCA Tejas Mark1A by February 2024.

New RWR on LCA Tejas Mark1A

Another noticeable point was RWR on LCA Tejas. Recently we have posted a detailed article on RWR and ASPJ being developed by DRDO for SU-30 MKI and LCA Tejas. These two EW components are next-generation weapons which are going to change the rules of arial engagement towards Indian Air Force.

The LCA Tejas Makr1A is going to feature 6 RWR around the aircraft providing it 360-degree coverage against hostile RF signal from missiles or FCR. The RWR can also transfer the data to self-protection jammer to jam the incoming hostile RF signal.

The video of LCA Tejas Mark1A flying with RWR hints that the aircraft development is at advance stage.

Tejas Mark-1A improvements

The Tejas Mk1A is going to be an upgraded version of the final operational clearance (FOC) configuration (Mk1) with 80 per cent of the detail components being the same. Tejas MK 1A will have 43 improvements over the Mark-1 version.

At present, the LCA is equipped with 344 systems — 210 are indigenous and 134 are imported, however in Mark-1A the imported systems will be reduced to about 80.

Many LRUs (Line Replaceable Units) will be re-positioned & new LRUs are to be included too, keeping in mind the maintainability easiness. IAF wants airframe panels that can be replaced without taking too much time and these will be supplied to the IAF with quick-release fasteners.

EW & Missiles

The major highlights of Mark-1A version is going to be indigenous UTTAM AESA radar, an electronic warfare (EW) suite that includes a jammer, the Combined Interrogator and Transponder (CIT) – an IFF plus system, a digital map generator, indigenous Beyond Visual Range missiles ‘Aastra’ and MBDA’s Advanced Short Range Air-to-Air Missile (ASRAAM).

The development trials of both Astra mark-1 and ASRAAM is planned to be complete before the delivery of Tejas Mark-1A starts. The carriage as well as the captive trials of both the missiles are complete and the next set of user and developmental trials is expected soon.

Tejas has already been integrated with Israel’s I-Derby ER and Python-5 missiles. I-Derby ER missile is a long-range air-to-air missile having an operational range of up to 100km with a maximum speed of Mach 4 & two-way data link. The Python-5 is the newest member of the Israeli Python family of short-range air-to-air missiles.
