Sigma Advanced Systems adds £125 million Rolls-Royce order to aerospace portfolio via UK subsidiary Bromford Precision Solutions

Sigma Advanced Systems has secured an additional long-term agreement valued at £125 million with Rolls-Royce, to be executed through Bromford Precision Solutions, a specialist aero-engine components manufacturer based in Leicestershire, UK, recently acquired by Sigma. The new deal builds on an earlier approximately £300 million (roughly ₹3,800 crore) long-term contract already signed with Rolls-Royce.

Under the contract, Bromford will manufacture aero-engine rings, casings, lock plates, and complex structural engine parts across Sigma's dual manufacturing hubs in India and the UK, delivering a multi-location supply chain directed by Rolls-Royce. Sunil Kalidindi, Chief Executive Officer and Executive Director of Sigma Advanced Systems, said the agreement shows how far India's precision engineering and defence-aerospace manufacturing base has come, and said global OEMs such as Rolls-Royce are looking to India not just for cost advantage but for engineering depth, quality, and scale. He said combining Bromford's UK capabilities with Sigma's India manufacturing network lets the company offer a dual-source solution.

Bromford is being integrated alongside Nasmyth, another UK subsidiary under Sigma's international aerospace platform. Sigma Advanced Systems, formerly known as Megasoft Limited, operates in design and precision manufacturing for defence electronics, aerospace, radar, and avionics.

This case sits alongside a broader pattern of large OEMs spreading engine-parts sourcing across multiple countries to combine cost, capacity and engineering depth in a single supplier group rather than a single site. Tier suppliers such as Sigma are positioning acquired UK plants like Bromford and Nasmyth as one integrated network with Indian facilities, so a customer like Rolls-Royce can direct components such as rings, casings, lock plates and structural parts to whichever hub suits capacity or programme needs.

For the aerospace supply chain, this kind of dual-source structure works only if both sites can be qualified to the same parts and quality standards, since the value pitched to the OEM is interchangeable capacity rather than just lower unit cost. What remains to be seen is how the £125 million and £300 million contracts are phased across Sigma's India and UK hubs, and whether further UK acquisitions are folded into the same platform alongside Bromford and Nasmyth.
