Stealthy Bridge: Can India's Tejas Mk2 Fill the Gap Until AMCA's Arrival?

The Stealthy Stopgap: Tejas Mk2's Potential as a Bridge to AMCA

The Indian defence ecosystem has long been abuzz with the idea of leveraging the Tejas Mk2 as a stealthy stopgap solution until the arrival of the fifth-generation AMCA fighter. This concept, which has been floating around for over a decade, gained renewed traction in recent years, with programme officials suggesting that the Tejas Mk2's frontal radar cross-section could drop to roughly 0.1–0.2 square metres in clean configuration, a nearly 75 percent reduction from the Mk1A.

A Stealth-Conscious Direction

The Tejas Mk2's design has indeed taken a significant leap towards stealth, with the incorporation of composite structures and stealth shaping. This has resulted in a substantial reduction in its frontal radar cross-section, putting it on par with far more expensive Western 4.5-generation jets. However, the Tejas Mk2's reliance on 11 external hardpoints weakens its radar-signature advantage, making it vulnerable to detection.

The Case for a Stealthy Tejas Mk2

A dedicated stealth outer fuselage with a small internal bay would address this issue, allowing for a limited air-to-air or precision strike loadout without spiking the RCS. This would provide a significant tactical advantage, particularly in first-day-of-war or contested-airspace roles where the standard Mk2 configuration would be more exposed. The proposal is intellectually sound, with genuine institutional precedent dating back to 2012, when DRDO chief V.K. Saraswat floated a similar idea.

The Challenge of Organisational Bandwidth

However, the biggest obstacle to this proposal has never been engineering feasibility, but rather organisational bandwidth and prioritisation. ADA and HAL's institutional bandwidth is already fully committed to getting the baseline Tejas Mk2 to first flight and AMCA through its Development Phase. Stretching resources towards a parallel stealth-variant project risks delaying both. Unless structured as a genuinely low-resource internal skunkworks effort running quietly alongside the main Mk2 and AMCA timelines, it risks facing the same fate as Saraswat's original 2012 pitch: a good idea that nobody pursued.

Key Takeaways

• The Tejas Mk2's design has taken a significant leap towards stealth, with a frontal radar cross-section reduction of nearly 75 percent through composite structures and stealth shaping.
• A dedicated stealth outer fuselage with a small internal bay would address the issue of reliance on external hardpoints, allowing for a limited air-to-air or precision strike loadout without spiking the RCS.
• The proposal for a stealthy Tejas Mk2 is intellectually sound, with genuine institutional precedent dating back to 2012, but faces significant organisational bandwidth and prioritisation challenges.
• The Indian defence ecosystem must carefully consider the feasibility and prioritisation of this proposal to ensure that it does not delay the development of the Tejas Mk2 and AMCA programmes.
