Order Details

Sigma Advanced Systems Limited has secured a significant order valued at USD 102.23 million (approximately INR 973 crores) for the manufacture and supply of Base Bleed (BB) Units for a NATO customer. The order execution is scheduled over a period of 12 months.

Product Description

The Base Bleed Unit is a specialized ammunition component designed to improve aerodynamic performance of artillery projectiles and extend their effective range. Integrated into the rear section of an artillery shell, the unit generates a controlled flow of gas during flight, reducing aerodynamic drag caused by the low-pressure region behind the projectile. This technology is widely used in modern 155 mm artillery ammunition and enhances range and operational effectiveness of long-range artillery systems.

Strategic Significance

The order represents a significant milestone in the company's strategy to expand capabilities across the 155 mm artillery ammunition manufacturing value chain. This development:

  • Strengthens Sigma's position within the artillery ammunition manufacturing ecosystem
  • Advances the company's strategy of vertical integration
  • Builds on existing capabilities in 155 mm artillery shells and fuzes
  • Enables development of more integrated offerings for the global artillery ammunition market
  • Reduces dependence on external suppliers and strengthens supply-chain control
  • Reinforces commitment to vertical integration and indigenous defence manufacturing
  • Aligns with the Government of India's Make in India initiative
  • Positions the company to address growing domestic and international demand for advanced artillery ammunition

Management Commentary

Sunil Kalidindi, CEO and Executive Director, stated: "In defence manufacturing, customer confidence is built on consistent execution, reliable delivery and the ability to scale. The fact that customers continue to place repeat orders with us reflects the trust we have earned by meeting our commitments on previous programmes. It also demonstrates that customers view Sigma as a dependable manufacturing partner, rather than an execution risk. As we deepen our capabilities across artillery shells, fuzes and Base Bleed Units, we are strengthening our position as a natural outsourcing partner for customers seeking reliable, integrated manufacturing capabilities. This order further reinforces our commitment to vertical integration, indigenous manufacturing and delivering comprehensive artillery ammunition solutions for domestic and international markets."
