Sigma Advanced Systems has secured an export order valued at USD 11.4 million, approximately INR 107 crore, from a North American customer for the supply of filled fuses used in 155 mm artillery shells. The contract involves the delivery of 90,000 units over a ten-month execution period and marks a major step in the company’s expansion within the global defense manufacturing ecosystem.
The order pertains specifically to Point Detonating M557 Filled Fuses, which form a critical component in 155 mm artillery ammunition systems. The company stated that manufacturing and execution will be carried out entirely through its in-house capabilities in India while adhering to all applicable defense export regulations and compliance standards.
The 155 mm artillery shell is among the most widely used artillery munitions globally and is compatible with a broad range of artillery gun systems currently deployed by defense forces across multiple countries. Demand for these systems has increased significantly in recent years due to evolving geopolitical conditions, rising military modernization programs, and growing defense preparedness initiatives worldwide. Sigma Advanced Systems said the export engagement reflects increasing international confidence in India’s defense manufacturing capabilities and highlights the company’s ability to deliver high-precision defense components for global markets.
Commenting on the development, Sunil Kalidindi, Chief Executive Officer and Executive Director of Sigma Advanced Systems, said the order represents an important milestone in the company’s growth journey as an international defense supplier.
According to Mr Kalidindi, the contract demonstrates the strength of the company’s engineering expertise, precision manufacturing capabilities, and research and development infrastructure built over decades of serving India’s defense sector. He added that the growing global demand for reliable artillery ammunition components presents strong long-term opportunities for the company in international defense supply chains.
The company stated that the products covered under the order have been developed using its Build-to-Spec expertise, which has been refined through years of supplying defense systems and components to Indian defense organizations and strategic programs. However, the latest order signals a strategic shift toward direct export engagements with overseas customers, highlighting the company’s increasing credibility as an independent supplier in global defense manufacturing.
The company indicated that the order could potentially lead to additional contracts and long-term engagements with the same customer, creating opportunities for recurring export business in the future. Sigma believes its strong in-house research and development capabilities provide a competitive advantage in securing repeat business, particularly in specialized and safety-critical defense systems that require high reliability and manufacturing precision.
The company currently operates across India and the United Kingdom and is expanding its presence into the United States market.
