India's Sigma Advanced Systems wins £125 million Rolls-Royce contract through UK subsidiary Bromford Precision Solutions
Why It MattersAero-engine OEMs are spreading critical-structure manufacturing across dual-source, cross-border supplier networks to secure capacity and cost advantages rather than relying on a single facility.
What happened
Indian defence and aerospace firm Sigma Advanced Systems has secured a new long-term contract worth approximately £125 million (about Rs 1,600 crore) with Rolls-Royce, executed through its recently acquired UK subsidiary, Leicester-based Bromford Precision Solutions.
The new agreement builds on a previously signed seven-year Rolls-Royce contract worth approximately £300 million (around Rs 3,800 crore), bringing the combined value of the two deals to nearly £425 million. Under the latest contract, Bromford will manufacture aero-engine rings, casings, lock plates and other critical engine structures across Sigma's manufacturing facilities in India and the UK, creating a dual-source manufacturing solution for Rolls-Royce.
Sigma acquired 100% of Bromford Precision Solutions for approximately £11.89 million (around Rs 153 crore) in July. Bromford, based in Leicestershire, manufactures high-precision aero-engine components including rings, compressor casings, ducts, brackets and lock plates, and holds approvals from Rolls-Royce and Siemens. Sigma CEO Sunil Kalidindi said the agreement is "another strong marker of how far India's precision engineering and defence-aerospace manufacturing base has come," adding that global aerospace original equipment manufacturers were increasingly looking to India for engineering capabilities, quality and scale, beyond cost advantages. Sigma operates aerospace and defence businesses in India and the UK, including subsidiaries Nasmyth and Bromford, manufacturing precision components and systems for global aerospace and defence customers.
Industry impact & what to watch
This deal follows a wider move by engine makers to lock in supplier capacity through acquisition-backed manufacturing rather than single-site contracts, spreading production of critical structures like rings and casings across two countries.
In aero-engine supply chains, dual-source arrangements let an OEM like Rolls-Royce hedge against disruption at any one facility while a supplier group like Sigma uses an acquired, already-approved subsidiary such as Bromford to win larger, longer contracts than either entity could secure alone. Existing approvals from Rolls-Royce and Siemens on Bromford's side lowered the barrier to qualifying the combined India-UK production base for new work.
What happens to the ring, casing and lock-plate output split between Sigma's Indian facilities and Bromford's Leicestershire site, and whether Rolls-Royce extends similar dual-source arrangements to other suppliers, will indicate whether this becomes a template for its wider component sourcing.
