In a scathing The Print column published on 10 December 2025, Admiral Arun Prakash (Retd), the former Chief of Naval Staff and a distinguished strategic thinker, has delivered a stark indictment of India’s aviation establishment.
His assessment is grim: despite ambitious rhetoric surrounding the fifth-generation Advanced Medium Combat Aircraft (AMCA) and the Twin-Engine Deck-Based Fighter (TEDBF), both programmes remain effectively grounded.
The cause is not a lack of funding or desire, but a 39-year-old failure that continues to haunt the Defence Research and Development Organisation (DRDO): the inability to produce a functional indigenous jet engine.
The Kaveri Stagnation: Four Decades of Missed DeadlinesThe heart of the crisis lies with the GTX-35VS Kaveri programme. Initiated by the DRDO's Gas Turbine Research Establishment (GTRE) in 1986—and formally sanctioned in 1989—the project was intended to power India’s Light Combat Aircraft (Tejas). Instead, it has become a case study in institutional inertia.
Admiral Prakash points out that after nearly four decades and the expenditure of billions of rupees, the Kaveri remains unfit for combat application.
Although first bench-tested in 1996, the engine has suffered from persistent technical setbacks, including thrust deficits, overheating turbine blades, and unreliable digital control systems. Every technical failure has been met not with a solution, but with a revised timeline that quietly shifts targets into the next decade.
