Sigma Advanced Systems has secured a $104.9 million (around ₹1,013 crore) export order from a North American customer for the manufacture and supply of 1.47 lakh units of 155mm base bleed artillery shell bodies.

The Hyderabad-based manufacturer of aerospace and defence precision components said the order will be executed over the next six to 12 months.

The programme involves manufacturing of precision-engineered artillery projectile casings designed for integration into extended-range ammunition systems. Unlike conventional artillery shells, which experience aerodynamic drag and turbulence at the base of the projectile during flight, base bleed shells incorporate a gas-generating unit at the rear that reduces this drag, significantly extending the effective range of the system while maintaining full compatibility with existing 155mm artillery platforms in service worldwide, Sigma said in a release.

The contract marks a technological progression for Sigma, which had previously secured orders for 155mm fuzes and M107 artillery shell bodies. Base bleed shells integrate advanced aerodynamics, energetics, propulsion technologies and systems engineering, representing a move up the value chain in artillery ammunition manufacturing.

The latest order aligns with Sigma’s strategy to move up the value chain in artillery ammunition, strengthen its engineering capabilities and programme credentials expected by global customers from their long-term strategic suppliers.

The order comes amid rising global investment in artillery modernisation, with defence forces across multiple regions focusing on ammunition stockpiling and extended-range fire-support capabilities to enhance operational readiness, Sigma said. The company’s shares closed 5% higher at ₹547.50 each on the BSE.
