Sigma Advanced Systems Wins ₹1,600 Crore Rolls-Royce Aero-Engine Deal, Expands India-UK Aerospace Manufacturing

Hyderabad-based Sigma Advanced Systems Limited has secured an additional long-term aerospace manufacturing contract worth nearly £125 million, or about ₹1,600 crore, from Rolls-Royce Aerospace UK, significantly expanding its presence in the global aero-engine supply chain. The agreement was disclosed on August 25, 2026, and will be executed through Sigma’s recently acquired UK subsidiary, Bromford Precision Solutions.

The contract covers the manufacture of aero-engine rings, casings, lock plates and other critical engine structures. Production will be distributed across Sigma’s manufacturing facilities in India and the United Kingdom, creating a dual-source manufacturing arrangement for Rolls-Royce and giving Sigma a larger role in supplying high-value components for international aerospace programmes.

The latest agreement follows an earlier £300 million, approximately ₹3,800 crore, seven-year contract secured from Rolls-Royce in April 2026 for high-precision aerospace components and assemblies. Together, the two recently announced agreements are valued at around £425 million, or roughly ₹5,400 crore, providing Sigma with substantial long-term revenue visibility and a deeper position within the Rolls-Royce aerospace supply network.

A key element of the latest expansion is Bromford Precision Solutions, the Leicestershire-based aerospace engineering company acquired by Sigma in 2026. Bromford specialises in precision aero-engine components and already holds established relationships and approvals within the global aerospace supply chain. The acquisition provides Sigma with additional capabilities in complex engine structures while maintaining an industrial presence close to major European aerospace customers.

The India-UK production model also allows Sigma to combine engineering and manufacturing capacity in India with established aerospace capabilities in Britain. This arrangement could improve supply-chain resilience for Rolls-Royce while gradually increasing the contribution of Indian facilities to sophisticated aero-engine manufacturing.

The contract is particularly significant for India because aero-engine components demand extremely high standards of metallurgy, machining precision, quality control and process certification. Participation in such long-duration global programmes can help Indian manufacturers move further up the aerospace value chain from conventional component production toward safety-critical and high-complexity engine structures.

Sigma has been steadily expanding its international aerospace and defence footprint through acquisitions and manufacturing partnerships. Alongside Bromford, the group also has operations through Nasmyth, giving it a growing industrial base spanning India and the United Kingdom. The latest Rolls-Royce agreement further integrates these capabilities into established global aerospace supply chains.

For India’s aerospace manufacturing sector, the significance extends beyond the size of the individual order. Long-term contracts from major global engine manufacturers provide domestic companies with access to demanding international production standards, advanced manufacturing practices and recurring aerospace programmes that can support investment in machinery, skills and engineering capability.

The ₹1,600 crore agreement therefore represents another step in the evolution of India’s aerospace industry from a lower-tier supplier toward a more integrated participant in global engine manufacturing. Combined with Sigma’s earlier Rolls-Royce contract, the company now has approximately ₹5,400 crore worth of recently announced business with the British aerospace major, strengthening both its international order book and India’s position in the global precision aerospace manufacturing ecosystem.
