Hyderabad-based Sigma Advanced Systems (SAS) has signed a seven-year long-term agreement worth nearly £300 million (app ₹3,800 crore) with aerospace major Rolls-Royce, marking a significant step in the company’s expanding global presence in the aerospace supply chain.
The contract involves supplying high-precision aerospace components through the company’s India-UK manufacturing network. This partnership strengthens Sigma’s position as an integrated global manufacturing platform and provides long-term revenue visibility in the aerospace sector.
Under this agreement, Sigma Advanced Systems will supply a wide portfolio of high-precision-engineered, safety-critical components and assemblies for Rolls-Royce’s aerospace programmes. This programme-level partnership will be delivered through the company’s manufacturing network across India and the UK, reflecting its evolution as an integrated global platform rather than a location-specific supplier.
The partnership builds on an existing relationship and signals continued confidence in SAS’ ability to operate as a globally integrated manufacturing platform. The company’s India-UK dual-source model brings together cost-efficient scale in India with proximity, engineering collaboration, and programme alignment in the UK.
This agreement represents SAS’ transition from a system player to a more integrated manufacturing partner capable of handling larger work packages. The partnership positions the company closer to the core of the aerospace supply chain, taking on larger and more complex roles in programmes that demand both scale and precision.
Beyond immediate business impact, the partnership delivers multi-year revenue visibility through a long-term order pipeline and reinforces SAS’ growth in long-duration, high-value aerospace programmes.
Chief Executive Officer and Executive Director of SAS, Sunil Kumar Kalidindi, commenting on the partnership said, “This partnership with Rolls-Royce reflects how our strategy is taking shape. It validates the investments we have made in building a connected India-UK platform and our focus on quality, reliability, and long-term partnerships. We see this as an opportunity to deepen our role in global aerospace programmes while continuing to scale our capabilities across both regions. We sincerely thank Rolls-Royce for the trust it has placed in us by awarding this long-term agreement.”
Sigma Advanced Systems operates as a globally integrated aerospace and defence company with more than three decades of manufacturing experience. The company operates across India and the UK, with expansion underway in the United States, and is among the largest India-headquartered manufacturers of aero-engine and aerostructure components. Sigma combines customer proximity in Western markets with India’s cost-efficient, talent-rich manufacturing base to deliver high-complexity, safety-critical components, assemblies, and systems across aerospace, defence, and emerging technologies.
At its core, the partnership builds on an existing relationship and signals continued confidence in SAS’ ability to operate as a globally integrated manufacturing platform. With proximity, engineering collaboration, and programme 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.
