Defence and Aerospace major, Sigma Advance Systems, deepens Rolls-Royce Aerospace UK partnership with £125m additional long-term agreement following strategic Bromford acquisition
Sigma Advanced Systems has secured a further long-term contract with Rolls-Royce through its recently acquired UK subsidiary, Bromford Precision Solutions based in Leicester, demonstrating the immediate strategic value of the acquisition and expanding the Group’s long-term relationship with one of the world’s leading aerospace OEMs.
Valued at nearly £125m (approximately Rs 1,600 crore), the agreement, which was signed on August 26, builds directly on the recently secured ~£300m (approximately Rs 3,800 Cr) Rolls-Royce long-term agreement, broadening the Group’s product offering, manufacturing capability and content across critical aerospace programmes. Together, the agreements significantly strengthen Sigma’s position within Rolls-Royce’s UK supply chain while increasing long-term revenue visibility.
The Bromford acquisition adds highly complementary manufacturing capabilities in aero engine rings and casings, and advanced precision manufacturing, enabling Sigma to supply a broader portfolio of complex engine components. Under the agreement, Bromford will manufacture aero-engine rings, casings, lock plates and other critical engine structures at Sigma’s India and UK manufacturing facilities, creating a more comprehensive dual-source solution as directed by Rolls-Royce.
This agreement highlights the strategic rationale behind Sigma’s acquisition of Bromford. By adding complementary products, specialist manufacturing expertise and long-standing OEM approvals, Bromford immediately expands Sigma’s addressable opportunity with existing customers while accelerating the Group’s progression towards higher-value, programme-level aerospace partnerships. Crucially, the agreement also secures Bromford’s long-term future within the Group, as a key UK manufacturing site, safeguarding skilled engineering and manufacturing jobs and reinforcing the resilience of the UK’s critical aerospace manufacturing base.
Sunil Kalidindi, Chief Executive Officer and Executive Director, Sigma Advanced Systems, said, “This agreement is another strong marker of how far India’s precision engineering and defence-aerospace manufacturing base has come. Global OEMs like Rolls-Royce are increasingly looking to India not just for cost advantage, but for engineering depth, quality and scale. By combining Bromford’s specialist UK capabilities with our integrated India manufacturing network, we are able to offer a genuinely global, dual-source solution. This is exactly the kind of high-value, long-term programme participation that India’s growing aerospace and defence manufacturing ecosystem is built for, and we are proud to be building it, one long-term partnership at a time.”
With Nasmyth and Bromford now operating as complementary businesses within Sigma’s UK aerospace platform, the Group continues to execute its strategy of building scale through targeted acquisitions that deepen customer relationships, broaden technical capability and increase participation in high-value, long-duration aerospace programmes.
