Indian Indigenous Aero Engine Developments


Sigma Advanced Systems has signed a seven-year long-term agreement with Rolls-Royce, marking a steady step forward in its global aerospace journey. The agreement represents a deepening strategic relationship with one of the world’s largest and most respected aerospace OEMs, placing the company at the heart of critical global engineering programs.

The contract is valued at nearly £300 million (i.e., roughly Rs 3800 cr), providing the company with a long-term revenue stream and stronger visibility over future growth.

Under the agreement, Sigma Advanced Systems will supply a wide portfolio of high-precision-engineered, safety-critical components and assemblies for Rolls-Royce’s aerospace programs. This is a program-level partnership delivered through the company’s manufacturing network across India and the UK, reflecting how the company is increasingly operating as an integrated global platform rather than a location-specific supplier.

At its core, the partnership builds on an existing relationship and signals continued confidence in Sigma Advanced Systems’ ability to operate as a globally integrated manufacturing platform. Leveraging its India-UK dual-source model, the company brings together cost-efficient scale in India. With proximity, engineering collaboration, and program alignment in the UK, the company cements its transition from a system player to a more integrated manufacturing partner capable of handling larger work packages.

As the company expands its global footprint, agreements like this point to a broader transition. Sigma Advanced Systems is steadily moving closer to the core of the aerospace supply chain, taking on larger and more complex roles in programs that demand both scale and precision.

Mitsubishi Heavy Industries, a defining proof point. We are also pleased to share another significant milestone. Azad has been awarded a prestigious contract by Mitsubishi Heavy Industries Japan as a single-source supplier partner. And we have signed an 8-year long contract
and purchase agreement for the supply of highly engineered hot section Nozzle Vanes segments for the combustion of a gas turbine engine.

Single source qualification for hot section components of a turbine nozzle vane for an OEM of MHI stature is the strongest possible endorsement of our technical and process capabilities. This product is not just being awarded, and it is awarded by many, many audits and many, many qualifications prior to even they think of awarding such product to any company.

On nozzle vane manufacturing process
But I can only give you one statement that there are only 3 players around the world of precision manufacturing that have been able to crack this materially, okay?

So the complexity in manufacturing these components is very, very high.

Q: All right. Okay. Okay. And on the Pratt & Whitney and the Rolls-Royce order book.
Yes. So in this 4 engine manufacturers on the airfoil is what we started. The first one was Rolls-Royce. So we have -- in H2, we are expecting to supply the first qualification batch. And once that is approved, and I think from -- we can see some momentum coming from Q4 FY '27 or early of FY '28.

That's where the supply starts. And followed by -- as you can see, it took 2.5, 2.5 years to come to the stage, and this is normal. And we could do it in 2.5 years. It's also a great thing. It's not a small thing to do it in 2.5 years. So same cycle will be followed. The next is Pratt & Whitney, then comes Safran and then it's followed by then.

Q: And secondly, if you could share your views on the potential benefits from upcoming engine ecosystem in the country.
So that is coming up. In terms of the engine ecosystem, I think I would make it broad-based even further saying that the opportunity that Azad today is sitting on, we've -- Azad has positioned itself always as a manufacturer of highly engineered critical components across these 3
segments, which are mission and life critical. With the demand for these engines going up over time with backlogs of our customers increasing, Azad is obviously looking at a much larger opportunity in this domain and which also means that the ecosystem in India should be thriving.

And with indigenization plans of the government, with indigenization plans of how we are stacking up, we are moving from building capability for one engine, and we will only scale it up like from the engine that we are building, we will move from the current 3.7 to 4 kiloton engine
to a higher capacity going forward and eventually contribute to much larger programs. But the entire engine ecosystem, we are seeing this demand grow and capacity is being added for -- a lot of capacity being added in the country.

We won't be able to talk too much about the Indian program. But yes, I see -- we see that India is going through that phase where we will now start contributing meaningfully to our GDP from a precision manufacturing industry perspective.
