But there was a moment at Farnborough this week when it was not aircraft orders that were being celebrated, nor the champagne toasts, but a quieter, yet potentially more important theme of the future of Indian manufacturing. Hindustan Aeronautics Limited (HAL) signed a long-term contract on the supply of superalloy turbine ring forgings for the CFM LEAP engine, the most popular turbofan powering most of the world's Airbus A320neo and Boeing 737 MAX aircraft. Unlike most of the orders for aircraft signed in this hall, this one doesn't come with a billion-dollar headliner, it doesn't involve any fighter jet, and yet it says a lot about India's future in the aerospace sector of the global market.

Knowing what a turbine ring forging is and why nobody would want to throw this job to any old guy is helpful in understanding why. They are the superalloy rings that spin inside the hottest and most highly stressed part of a jet engine, at high temperatures for tens of thousands of hours without failing. If the metallurgy is wrong, or the tolerances, then you don't get a warranty claim, you get a catastrophic incident. At its own facility, the Foundry and Forge Division (FFD) at Bengaluru, situated in the Ring Rolling, these will be manufactured at the company's Near Net Shape Forgings (NNSF) plant which has been under development for years and earned the company the right to engage in this class of work. It was a small ceremony that involved the presence of HAL's General Manager of Foundry and Forge, Praveen B, and Safran's purchasing chief Dominique Dupuy and it marks a full formalisation of a chain of events that began with a memorandum of understanding in October 2023, expanded to an actual forged-parts contract during Aero India in February 2025, and now culminated in a formal supply commitment.

That's more important than signing one player. Global engine manufacturers will not send a supplier increasingly sensitive, safety-critical components until all of the previous steps are done cleanly and audited to the hilt. India's watching, quietly, as a domestic public-sector enterprise progresses further up the value chain from “bulk metal bending” to making precision, engineering-grade components, which involve real intellectual and financial risks. That's the true story, that transition away from cost arbitrage to technical trust earned, and it's coming at a time when the commercial engine industry is in desperate need of new trusted hands.

The timing is no coincidence. It's a maintenance and production problem that's become one of the defining issues of commercial aviation, the LEAP program and its rival Geared Turbofan by Pratt & Whitney are both facing. The study by IATA and consultancy Emerton revealed a joint groundings record of 648 aircraft in March last year, representing nearly 28 percent of the total aircraft count, and a massive ramp up in the number of aircraft visiting LEAPs for annual inspections from about 600 to more than 5,000 by 2040. That's a load the maintenance and parts supply industry simply can't handle, and that's why, during this year's Farnborough, airlines and lessors ordered engines that outstripped most of the aircraft orders. IndiGo alone ordered over 1,000 LEAP-1A engines, which it said was the largest order in CFM International's history, while its lessor BOC Aviation pledged up to 300 LEAP engines and 220 GTFs, which it described as its biggest engine transaction ever. All those engines require forged parts, and each other source equals less of a delay in aircraft deliveries all over the world.

The performance, set against India's own numbers, is no longer a one-off success but seems more like a sector slowly getting into gear. Domestic defence production has crossed the cusp of 1.78 lakh crore rupees in the past financial year, exports have increased by nearly thirty times in the last decade and the India aerospace and defence market (valued at around 31 billion dollars this year) is projected to grow steadily in the coming decade due to the indigenisation initiatives which now mandate 75% of military modernisation expenditure to come from domestic sources. At HAL, the ratio of R&D investment to revenue is about 9 percent, well above the average of most of the world's engine makers, and a reason for a French engine maker to keep strengthening the link. The honest disclaimer must be in the same breath though: India's public sector military giants, including HAL, sell a mere one per cent of global arms, a testament to how much field time is left before the nation earns a reputation for manufacturing.

This move is part of a trend that manufacturers have been quietly following since supply chains were severely impacted by the pandemic. This means that over 70% of aerospace systems remain sourced from the United States and Europe, and OEMs have been scouting for viable alternatives in Asia to lessen the risk of relying on the former sources. Despite having a pool of engineers and an affordable cost base, India has been touted as the solution for years, but pitches that turn into contracts require some proof that the supplier can maintain tolerances at scale, on schedule and without drama. This forging agreement does just that. Now, the next step for HAL and others is to see if they can get up a notch higher from a forging shop that just makes someone else's design to one that actually holds intellectual property rights on subsystems. That's the test to see if India emerges as a reliable back office for aviation or one of its true engineers, and it's not any one ceremony at any British air base.
