Tejas Mk2 is planned to take its first flight in 2023

Tejas MK2 

Despite several months of Lockdown due to the Chinese Virus situation in the country, the Aeronautical Development Establishment (ADE) which is the nodal design agency for the Tejas Mk2 program is confident that the first rollout of the Tejas Mk2 LSP-1 will happen in June 2022 and it will conclude its first flight by Early 2023. 

The first Metal cutting for the first aircraft is scheduled for February 2021, Hindustan Aeronautics Limited (HAL) already has begun procurement of tooling and assembly jigs for the same and the final design freeze will happen in the next few weeks. ADE and HAL are getting to complete flight testing and Developmental trials by 2028 in order that aircraft enters into full-scale production by then. 

Unlike the Tejas Mk1 program, the Tejas MK2 program are going to be build using technologies and components which are already developed, and zip much must be developed which may delay the program thanks to which Schedule has remained an equivalent

Tejas Mk2 will feature Side Stick Controller, Next Generation Wide Area Display (WAD) to spice up situational awareness, accuracy, safety. Electronic warfare suite (EW suite) onboard and On-board Oxygen (OBOX) generating system which is already developed and tested. HAL is additionally developing Two Full Mission Simulator (FMS) for the program in order that Pilots can practice and fly it even before the primary Mk2 LSP-1 is prepared for its first flight. 

ADE already has received dozen F-414 engines from GE, a replacement powerful digital control computer (DFCC) already has been developed which can even be used for the Tejas Mk1A program. Most of the main system like Line Replacement Unit (LRU) and Avionics is already developed and what's now required is to place them in one place which will happen when the assembly of the first aircraft begins from mid of 2022 onwards. 

LSP-1 Tejas Mk2 will be an Initial Operational Clearance (IOC) standard built and in by 2026 first Final Operational Clearance (IOC) standard built LSP-3 will be ready for further flight testing in order that by 2028 it's able to enter production. 17.5 ton Tejas Mark II are going to be powered by a heavier GE 414 engine and can be equipped with state-of-the-art AESA radar with the indigenously developed Weapons systems like RudraM, BrahMos-NG, Astra Mk1, Mk1A, Mk2 BVRAAM, SAAW, etc. 

Tejas Mk2 will share 80% of its Avionics, Radar, and other major systems with the Navy’s TEDBF program also. Tejas Mk2 program was sanctioned in 2009 but the bulk of the systems required for the aircraft were developed first albeit aircraft moved from 15-tonne aircraft to 17.5-tonne aircraft in the last 5 years in the design stage itself due to growing confidence in Tejas MK1.

About Tejas MK2

Other than design commonalities very little major technologies has been forwarded from its predecessor Tejas Mk1/A. Instead more of its technologies are to be borrowed from whatever has been developed for the 5th Generation fighter jet program of India, AMCA. Several radar cross-section reducing measures will be incorporated in the airframe design so that a degree of frontal stealth can be achieved, including Radar-absorbent material coating and composites making up its skin, twisted air-intake ducts..

The aircraft will be equipped with a multi-sensor data fusion system which will feature an active electronically scanned array radar, infrared search and track and a missile approach warning system. It will also feature an internalized integrated electronic warfare suite. The aircraft will be designed to have network-centric warfare capacity.

ADA is planning to integrate Uttam AESA radar on Tejas Mk 2 in collaboration with Electronics and Radar Development Establishment (LRDE). Indian variant of Rafales are to sport Thales X-Guard fiber-optic towed decoy system and Traffic Collision Avoidance System (TCAS), which may be carried over to the MWF. 

Medium Weight Fighter's cockpit is to have a next-generation Wide Area Multifunction Display, and side-mounted control stick.

The aircraft is planned to be equipped with an artificial intelligence based “optimally manned” cockpit. The cockpit will be designed such that the ground control would be able to takeover the controls of the aircraft in case the pilot becomes unconscious, after being alerted by a sensor in the helmet of the pilot.
