The dream of a home-grown stealth fighter isn't new for India. It’s been floating around the hallways of the DRDO (Defence Research and Development Organisation) and the IAF (Indian Air Force) for well over a decade now. We are talking about the India medium combat aircraft, officially known as the AMCA (Advanced Medium Combat Aircraft). Honestly, if you look at the global landscape of fifth-generation fighters, it’s a tiny, exclusive club. You have the American F-22 and F-35, the Russian Su-57, and the Chinese J-20. That is basically it. For India to try and barge into this group is a massive undertaking. It’s not just about building a plane that flies; it’s about mastering materials that deflect radar, engines that don’t melt under insane pressure, and software that can think faster than a human pilot.
It’s complicated.
Most people look at the delays and roll their eyes, but the sheer physics of stealth is a nightmare. The AMCA is designed to be a twin-engine, multi-role fighter. It’s meant to replace the aging Jaguars and Mirages, and eventually, the MiG-29s. But unlike the Tejas, which is a light fighter, the India medium combat aircraft is a heavyweight in terms of technological ambition. We're looking at a 25-tonne bird that needs to hide from the world’s most sensitive radar systems while carrying a lethal payload internally. If you put bombs on the wings, you might as well put a giant "here I am" sign on the radar screen. So, the internal weapons bay is a non-negotiable requirement.
The Engine Problem Nobody Wants to Talk About
Let’s get real about the engine. This is the Achilles' heel of Indian aerospace. For years, the Kaveri engine project struggled to meet the thrust requirements for the Tejas, let alone a fifth-generation stealth platform. For the AMCA Mark 1, the plan is to use the US-made GE-F414 engines. It’s a solid, reliable choice. It’s the same engine used in the Super Hornet. But here is the catch: a stealth fighter using a fourth-generation engine is kinda like putting a Camry engine in a Ferrari body. It’ll move, but it won’t scream.

The real magic is supposed to happen with AMCA Mark 2.
India wants to co-develop a 110kN engine with a foreign partner, likely Safran from France or Rolls-Royce from the UK. This is where the "sovereign capability" talk gets real. Without an engine that has a high thrust-to-weight ratio and supercruise capability—which is the ability to fly at supersonic speeds without using gas-guzzling afterburners—the AMCA is just a very expensive, very quiet target. The CCS (Cabinet Committee on Security) finally cleared the funding for the AMCA prototype in early 2024, allocating roughly 15,000 crore rupees. That sounds like a lot, but in the world of stealth, it’s a down payment.
Stealth isn't Just a Shape
You’ve probably seen the jagged edges and the tilted tails on stealth planes. That’s the "form" part of stealth. But the "substance" is the Radar Absorbent Material (RAM). This stuff is basically a secret sauce of chemicals and composites that soak up electromagnetic waves. If the paint isn't right, the plane glows on radar. India’s ADA (Aeronautical Development Agency) has been working on indigenous RAM, but applying it and maintaining it is a logistics horror story.
Think about the maintenance. Every time a panel is opened for repairs, the stealth coating has to be reapplied or patched perfectly. One loose screw or a slightly misaligned seam can spike the Radar Cross Section (RCS). The India medium combat aircraft aims to have an RCS comparable to the best in the world, but achieving that on a production line in Nashik or Bengaluru is a world away from a laboratory test.
Then there’s the "brain" of the aircraft.
We’re talking about sensor fusion. In an old fighter, the pilot looks at a radar screen, a RWR (Radar Warning Receiver) display, and maybe a targeting pod. In the AMCA, the pilot shouldn't have to look at three different things. The computer takes all that data—infrared, radar, electronic intelligence—and merges it into a single picture. It’s basically God-mode for pilots. Developing the algorithms to do this without crashing the system is why software is now the most expensive part of any fighter jet.
Why Not Just Buy the F-35?
This question pops up in every defense forum. Why spend twenty years and billions of dollars developing the India medium combat aircraft when the US might eventually sell the F-35 to India?
Strategic autonomy.
If you buy American, you play by American rules. You can't usually integrate your own missiles without their permission. You can't always fly it where you want without their "support" (which is a polite word for oversight). India has always been fiercely protective of its right to use its hardware how it sees fit. Plus, building the AMCA creates a massive ecosystem of private defense players in India. Companies like Tata and L&T are already deeply involved in aerospace. If India skips the AMCA, it effectively kills its dreams of being a global aerospace power.
The Timeline: A Reality Check
Don't expect to see a squadron of AMCAs defending Indian skies by 2027. That is just not happening. The first flight of the prototype is currently targeted for 2028 or 2029. After that, you have years of flight testing. Weapons integration. Stealth validation. High-altitude trials in Ladakh. Tropical trials in the south. If everything goes perfectly—which it rarely does in aviation—the Mark 1 might enter production by 2032 or 2033.
The Mark 2, with the more powerful engine and sixth-generation technologies, is a mid-to-late 2030s story.
Is that too late? Some critics say yes. By 2035, the rest of the world will be flying sixth-generation "loyal wingman" drones and laser-armed platforms. But India’s approach is incremental. You have to walk before you can run. By building the Tejas Mk1, then the Mk1A, and then the Mk2 (which is also under development), India is building the industrial muscle needed to actually manufacture the India medium combat aircraft. It’s a long game.
What Actually Happens Next?
If you are following the progress of the AMCA, keep your eyes on the "Metal Cutting" ceremonies. That’s the industry term for when they actually start machining the parts for the first prototype. Until then, it’s mostly digital designs and wind tunnel models.
The next few years are critical for two reasons:
- The Engine Deal: Watch for a concrete agreement between India and a foreign OEM (Original Equipment Manufacturer) for the 110kN engine. If this stalls, the Mark 2 stalls.
- Private Sector Integration: The IAF and the government have been vocal about the AMCA being a Special Purpose Vehicle (SPV) model. This means a private company will likely lead the production alongside HAL. This is a huge shift from the old state-run monopoly.
The AMCA isn't just a plane. It’s basically a test of whether India can truly become a global superpower. You can't be a superpower if you're always buying your toys from someone else. The India medium combat aircraft is the most ambitious engineering project in the country's history. It’s risky, it’s expensive, and it might fail. But for the Indian Air Force, failure isn't really an option when your neighbors are already fielding stealth platforms.
Actionable Insights for Following the AMCA Project:
- Monitor DRDO annual reports for updates on "Gallium Nitride (GaN) based radar technology," which is the heart of the AMCA’s AESA radar.
- Track the LCA Tejas Mk2 progress; many of the flight control laws and sensors for the AMCA are being tested on the Tejas Mk2 first to de-risk the project.
- Look for "Joint Venture" announcements involving the Indian private sector and engine manufacturers; the finalization of the engine partner will be the single biggest indicator of the project’s long-term viability.
- Differentiate between Mark 1 and Mark 2; many news reports confuse the two. Mark 1 is the "interim" version with US engines, while Mark 2 is the "full-spec" stealth fighter India actually wants.
