Hyderabad-based Sigma Advanced Systems has announced that it has secured an export contract valued at US$21.97 million (approximately Rs 208 crore) to manufacture and deliver 40,000 units of 155 mm M107 artillery shell bodies to a customer in North America. The company stated that the order must be fulfilled within a six-month timeframe, with production and deliveries scheduled for completion within that period.
Contract Details and Production Scope
The contract involves the production of 155 mm shell bodies, which are critical structural components of artillery ammunition. These components require advanced metallurgical expertise, high-precision machining, heat treatment, and stringent quality assurance to ensure reliable performance under extreme operational conditions. Sigma Advanced Systems has already obtained the necessary export authorization from the Department of Defence Production under the Ministry of Defence.
Industry Demand and Strategic Expansion
The demand for 155 mm ammunition components has been rising globally, as this calibre remains the standard for modern artillery systems and is widely used across NATO and allied platforms. This contract marks a strategic expansion for Sigma, moving beyond its previous focus as a fuze manufacturer into complete artillery shell component production. The company now possesses dual capability in key ammunition subsystems, strengthening its profile as an end-to-end engineering and precision manufacturing partner for global defence customers.
The scale of the order underscores Sigma’s capacity to execute high-volume, mission-critical manufacturing programmes for international clients. Sunil Kalidindi, CEO and Executive Director of Sigma Advanced Systems, stated, “This contract reflects the confidence international customers place in India’s defence manufacturing ecosystem and in Sigma’s ability to deliver complex, high-precision products at scale.”
Global Defence Supply Chain Presence
Sigma highlighted that this deal enhances its credentials in global defence supply chains, amid a broader shift toward diversified and reliable manufacturing partners. The company operates across India and the United Kingdom, with expansion activities underway in the United States.
