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

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 maintain
