HAL Tejas Mk2: Indian Air Force’s Latest Fighter Craft In The Making

Over the years, India's defence sector has made significant advancements in aerospace technology, with the HAL Tejas program as a prime example. With the Hindustan Aeronautics Limited (HAL) Tejas Mk2, a highly ambitious upgrade of its predecessor, the Indian Air Force (IAF) is all set to fortify its operational capacity. The Tejas Mk2 is, therefore, more than a fighter jet; it showcases India's aspirations with improved performance metrics and enhanced features and technology.

Development of Tejas Program

The Tejas program began in the 1980s as part of India's Light Combat Aircraft (LCA) project to replace the country's ageing fleet of MiG-21 fighter aircraft. The Tejas Mk1, which India has been able to gift itself to join the league of countries that can produce fighter jets at home, has been designed and developed through a collaboration between HAL and the Aeronautical Development Agency (ADA). Although the Tejas Mk1 and its enhanced derivative, the Mk1A, have demonstrated operational prowess, their low range and payload capacity made a stronger platform necessary. Enter the Tejas Mk2, a medium-weight multirole fighter intended to fill the gap between the lightweight Tejas Mk1 and heavier offerings like the Rafale.

Key Features of HAL Tejas Mk2

Size and Payload Capacity: Larger and more powerful than the preceding Tejas Mk1, the Tejas Mk2 has many other upgrades. With a length of 14.6 meters and a wingspan of 8.5 meters, the Mk2 is larger than the Mk1, which measures just 13.2 meters long with a wingspan of 8.2 meters. This extra size means a larger payload of 6500 kilograms, nearly double that of the Mk1.
Engine and Performance: The General Electric F414-INS6 engine that will power the Mk2 musters 98 kN of thrust, while the Mk1 has the F404-GE-IN20 engine that produces 84 kN. This increased power translates into increased speed, manoeuvrability, and range, with the aircraft achieving a top speed of Mach 1.8 and a combat radius of around 1,500 kilometres.
Stealth and Survivability: It uses stealth features, including a reduced radar cross-section (RCS) and an infrared signature. Structures such as composite materials, radar-absorbing coating, and internal weapons bay contribute to its lesser detectability, making it an effective adversary in modern air combat.
Avionics and Sensors: The Tejas Mk2 is fitted with advanced avionics, including an indigenous Active Electronically Scanned Array (AESA) radar, Infrared Search and Track (IRST) system, and Electronic Warfare (EW) suite.
Multirole Capability: Tejas Mk2 is expected to be a true multirole fighter capable of air superiority, ground attack, maritime strike and reconnaissance roles.
Digital Cockpit and Pilot-Centric Design: The aircraft incorporates a fully digital cockpit and utilises advanced fly-by-wire systems, All touch-screen displays, and a Holographic head-up display (HUD). The cockpit layout is focused on decreasing pilot workload to enable better executions.

The Technology, Strategic Resource and Indigenous Development

The Tejas Mk2 is a major milestone in realising the government of India's vision of "Atmanirbhar Bharat" (self-reliant India) . The aircraft carries a higher Indigenous content than its predecessor, signifying the growing maturity of India’s Indigenous defence manufacturing ecosystem. Key Indian organisations, such as Bharat Electronics Limited (BEL), Bharat Dynamics Limited (BDL), DRDO labs , and others, are supporting subsystems like avionics, radars, weapon systems, etc. By collaborating domestically, they enhance innovation and create jobs, removing dependence on foreign suppliers. From a strategic point of view, the Tejas Mk2 meets India’s requirement of adding muscle to a beleaguered air force constantly complaining of a low fighter squadron strength. Expected to play a critical role in ensuring air dominance in the theatre, the platform is set to be mandated for about 120 Tejas Mk2 jets.

How Does It Compare to Global Peers?

The Tejas Mk2 is pitched as an affordable alternative to Western combat aircraft like the F-16 Block 70, Saab Gripen E, and JF-17 Thunder. Although the F-16 Block 70 offers proven combat reliability, and the Gripen E is the product of cutting-edge technologies, the Tejas Mk2 brings the ruba of indigenous nature and low lifecycle cost. The Tejas Mk2, which has significantly more powerful engines, advanced avionics and payload capabilities than Pakistan's extensively exported JF-17 Thunder, will offer a better platform for various mission profiles. Compared to more sophisticated jets like the Dassault Rafale and Lockheed Martin’s F-35, the Tejas Mk2 isn’t in the ballpark regarding stealth and network-centric combat capabilities. Nevertheless, its low price and simple logistical footprint make it an appealing option for countries needing a dependable multirole fighter.

Challenges and Road Ahead

The Tejas Mk2 program is promising but has a mountain to climb. Development delays, cost overruns, and integrating new technologies are formidable challenges. Timely certification and production to meet the IAF’s requirements is another important job for HAL and ADA. The other is getting export orders. While the Tejas Mk2 is attractive due to its affordability and multirole capabilities, its operational performance must be proven in scenarios to gain global trust and demand. Nonetheless, the Indian government’s deep interest in and commitment to defence modernisation, combined with HAL’s growing capabilities, constitute a poor recipe for success for the program. The latter has been progressively promoted through international agreements and trans-technology transfers over the past decades.

Conclusion

The HAL Tejas Mk2 is a massive next step for India's indigenous fighter jet program. For the IAF, it is a trump card with its new features, enhanced capability, and operational significance. Despite the speed bumps in the road, the successful development and deployment of the Tejas Mk2 will bolster India’s defence capabilities and reaffirm its status as an emerging aerospace power on the global stage. Significantly, now in the making, the Tejas Mk2 represents a long-term commitment to a fighter all its own, which demonstrates India’s ambition, technological ingenuity, and self-reliance in defence material. But the skies are the limit for India’s aerospace dreams, and in the years to come, the Tejas Mk2 is all set to fly high.
