As global aerospace powers—the United States, China, and Europe—forge ahead with at least four distinct sixth-generation fighter jet programs, the urgency for India, home to the world’s fourth-largest air force, to initiate its own conceptual work on next-generation air combat platforms has never been greater.
With the Indian Air Force (IAF) already committed to the development of the Advanced Medium Combat Aircraft (AMCA), a fifth-generation stealth fighter, the time is ripe to begin exploring sixth-generation concepts. Doing so would ensure that India avoids playing catch-up once the AMCA enters service, positioning the nation as a competitive player in the future of air warfare.
Sixth-generation fighter programs are redefining the boundaries of air combat, promising unprecedented capabilities such as advanced stealth, artificial intelligence (AI)-driven decision-making, networked warfare, directed-energy weapons, and optionally manned or fully unmanned configurations. The United States is advancing its Next Generation Air Dominance (NGAD) program for both the Air Force and Navy, aiming to field a family of systems by the 2030s. China is reportedly developing its own sixth-generation platform, with state media hinting at progress in AI integration and hypersonic technologies. In Europe, two collaborative efforts—the UK-led Tempest program (involving Italy and Japan) and the Franco-German-Spanish Future Combat Air System (FCAS)—are pushing the envelope with modular designs and swarm drone integration.
These programs share common themes: enhanced connectivity, cognitive warfare, and adaptability to multi-domain operations. Unlike fifth-generation fighters, which prioritize stealth and sensor fusion, sixth-generation platforms are envisioned as “systems of systems,” orchestrating manned jets, loyal wingman drones, and space-based assets in real-time. For India, observing these developments from the sidelines risks technological obsolescence in a rapidly evolving threat landscape.
India’s aerospace ambitions are currently centered on the AMCA, a twin-engine, stealth-capable fifth-generation fighter designed to meet the IAF’s need for a modern multirole platform. Spearheaded by the Aeronautical Development Agency (ADA) and Hindustan Aeronautics Limited (HAL), the AMCA is expected to feature supercruise, advanced avionics, and indigenous radar systems. The program aims for a first flight by 2028 and induction by the mid-2030s, with two variants: a Mark 1 with General Electric F414 engines and a Mark 2 with a more powerful indigenous engine under development.
While the AMCA represents a significant leap for India’s defense industry, its timeline suggests that by the time it enters service, sixth-generation fighters will already be shaping global air forces. The IAF, with approximately 1,700 aircraft (including fighters, transports, and helicopters), is a formidable force but faces challenges with an ageing fleet of MiG-21s, Jaguars, and Mirage 2000s. The AMCA is critical to replacing these platforms, but India must look beyond to ensure long-term air superiority, particularly in a region where China’s J-20 and potential sixth-generation platforms pose growing threats.
Why India Needs a Sixth-Generation Program Now
Initiating conceptual work on a sixth-generation fighter does not mean diverting resources from the AMCA but rather laying a strategic foundation for the future. Several compelling reasons underscore the need for India to act promptly:
- Avoiding the Catch-Up Trap: India’s fighter development has historically lagged global trends, with programs like the Light Combat Aircraft (LCA) Tejas taking decades to mature. Starting sixth-generation research now—while the AMCA is in development—would allow India to build expertise in cutting-edge technologies like AI, quantum computing, and directed-energy weapons, preventing a technological gap when fifth-generation platforms become outdated.
- Regional Security Dynamics: China’s aggressive military modernization, including its sixth-generation ambitions, poses a direct challenge to India. With border tensions along the Line of Actual Control (LAC) and China’s expanding air presence in the Indo-Pacific, India needs a next-generation platform to maintain deterrence and counter Beijing’s numerical and technological edge.
- Technological Leapfrogging: Sixth-generation fighters will rely heavily on AI, machine learning, and human-machine teaming. India, with its burgeoning tech sector and expertise in software development, is well-positioned to innovate in these areas. Early investment in these technologies could yield breakthroughs that enhance both the AMCA and future platforms.
- Global Partnerships and Influence: Joining the sixth-generation race could open doors for collaboration with allies like the United States, France, or the UK, which are already exploring such programs. India’s participation in Japan’s Tempest program as an observer is a step in this direction, but a domestic initiative would strengthen India’s bargaining power and ensure technology transfers align with national interests.
- Industrial Ecosystem Development: A sixth-generation program would catalyze India’s defense industry, fostering advancements in materials science, propulsion, and cybersecurity. It would also create high-skill jobs and incentivize private-sector participation, building on the momentum of “Make in India” initiatives.
