Sigma Advanced Systems has begun production at its new aerospace manufacturing facility in Sri City, Andhra Pradesh. The company completed the transition from groundbreaking to active operations in eight months. Co-CEO Sunil Kalidindi stated the facility is central to global manufacturing strategy and the company aims for double-digit EBITDA growth.
The initial phase involves a 75,000 sq ft operational area within a larger 500,000 sq ft campus. This first batch of precision-machined aerospace components has been manufactured and shipped to Sigma UK for final verification. The facility currently offers 100,000 annual machining hours of capacity.
Operational Scale and Capability
The Sri City operation is designed to replicate the manufacturing capabilities of Sigma’s UK subsidiaries, Nasmyth and Bromford. The company has completed the initial stages of the source-change approval process with Rolls-Royce Aerospace.
| Metric | Current Status | Future Capacity |
|---|---|---|
| Operational Area | 75,000 sq ft | 500,000 sq ft (campus) |
| Annual Machining Hours | 100,000 AMH | Nearly 300,000 AMH |
| Production Share (India) | Initial Batch | ~70% of process |
Sunil Kalidindi, Chief Executive Officer and Executive Director, stated that the objective is to progressively bring a larger part of the aerospace manufacturing value chain into India. The remaining campus is expected to become operational in the next 12 months, adding further aerospace-critical processes.
What the Numbers Show
The rapid deployment of 100,000 machining hours within an eight-month build-out period highlights the efficiency of the greenfield project execution. With the facility budgeted to scale to nearly 300,000 AMH, the current capacity represents approximately one-third of the immediate target, indicating significant near-term upside in utilization rates as NADCAP accreditation progresses.
Strategic Outlook
Sigma expects the Sri City operation to employ more than 500 people over the next two to three years. The location was selected for its connectivity to four major ports, supporting export-oriented operations. The company plans to develop specialized aerospace manufacturing skills through on-campus training.
This facility forms part of a broader strategy to establish a multi-site aerospace manufacturing footprint across India and the UK. Once fully operational, approximately 70% of the manufacturing process is expected to be undertaken in India.
