Sigma Advanced bags $104.9 million base bleed artillery shells export order

Sigma Advanced Systems has secured a $104.9 million export order to supply 155mm base bleed artillery shells to a North American customer. The contract represents a significant technological advancement for the Hyderabad-based firm as it expands its role in the global artillery modernization market.
Why it matters
This deal highlights the growing global demand for advanced defense manufacturing and the increasing integration of Indian firms into international military supply chains.
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.
