Sigma bags $19.7 million artillery subsystems order from North American customer

Aerospace and defence engineering and manufacturing company Sigma Advanced Systems has secured an order valued at $19.70 million (around ₹174 crore) from a North American customer serving the NATO defence ecosystem for the manufacture and supply of specialised ancillary subsystems for 155 mm artillery ammunition.

The order is scheduled to be executed by Q2 2027 with the manufacturing to be undertaken within the Sigma ecosystem, the company said on Wednesday.

Sigma said the order marks its fifth 155 mm engagement since May 2026 and reflects the expansion of its capabilities across the artillery ammunition value chain. With shell bodies, filled fuzes, advanced base-bleed shell technology, course-correction fuze collaboration and ancillary subsystems within its portfolio, the company is progressing beyond individual ammunition component supply towards a broader manufacturing and engineering partnership across multiple elements of the artillery round.

“Global defence customers are looking beyond individual components to partners who can support increasingly complex manufacturing requirements across the ammunition supply chain. This order builds on the capabilities Sigma has developed across the 155 mm segment and marks a further step in broadening our role in international defence manufacturing,” CEO Sunil Kalidindi said.

The focus is on building capabilities that will pave the way to participate in more technically demanding programmes and respond to customers’ evolving requirements, he said.

In a release announcing the order from the North American customer, the company said the Russia-Ukraine war has highlighted the scale of artillery ammunition consumption in high-intensity conflicts and the importance of sustained industrial capacity. NATO members and allied governments have responded by prioritising inventory replenishment, longer-term procurement and expansion of ammunition manufacturing capabilities.

The European Union’s Act in Support of Ammunition Production (ASAP), launched in 2024 with €500 million in funding, was designed to address production bottlenecks and strengthen Europe’s ammunition manufacturing base. NATO has also advanced initiatives focused on aggregating demand, supporting multi-year procurement and expanding industrial capacity.

For manufacturers such as Sigma, this creates opportunities to establish deeper positions within international defence programmes, it said.
