Sigma Advanced Systems Secures ₹174 Crore Export Order for 155mm Artillery Ammunition Subsystems

Hyderabad-based aerospace and defence manufacturer Sigma Advanced Systems Limited has secured an export order worth US$19.7 million, approximately ₹174 crore, for specialised subsystems used in 155mm artillery ammunition. The order, announced on October 21, 2026, comes from a North American customer serving the NATO defence ecosystem and represents another important expansion of India’s participation in international ammunition manufacturing supply chains.

The contract covers the manufacture and supply of specialised ancillary subsystems for 155mm artillery ammunition. Sigma will undertake manufacturing within its industrial ecosystem, with execution scheduled for completion by the second quarter of 2027.

The company disclosed the development to the Bombay Stock Exchange and National Stock Exchange on October 21 under Regulation 30 of the SEBI Listing Obligations and Disclosure Requirements Regulations. The announcement marks Sigma’s fifth engagement in the 155mm artillery ammunition segment since May 2026, reflecting its expanding manufacturing capabilities across different categories of ammunition components.

₹174 Crore Order Expands Sigma’s International Defence Manufacturing Business

The latest export order strengthens Sigma Advanced Systems’ position in the international artillery ammunition manufacturing sector. The North American customer operates within the supply chain serving the NATO defence ecosystem, providing Sigma with another opportunity to participate in international defence programmes.

The contract focuses on specialised ancillary subsystems, extending the company’s manufacturing activities beyond artillery shell bodies and fuzes. These subsystems form part of the broader ammunition production value chain, where different components must meet demanding engineering, manufacturing and quality requirements.

Sigma has been progressively expanding its capabilities in precision manufacturing, metallurgy, fuze technologies and associated ammunition components. The new order adds another product category to this portfolio and supports the company’s transition towards providing broader engineering and manufacturing solutions.

The company intends to execute the contract through its existing manufacturing ecosystem, strengthening its participation in international defence supply chains while expanding the range of products manufactured for overseas customers.

Fifth 155mm Artillery Ammunition Engagement Since May 2026

The October 21 announcement represents the fifth major milestone in Sigma Advanced Systems’ expanding 155mm artillery ammunition business since May 2026.

In May, the company secured an order worth US$11.4 million for filled fuzes used in 155mm artillery ammunition. This engagement strengthened its position in the manufacture of specialised ammunition components and established a foundation for further expansion.

In June 2026, Sigma received an export contract valued at US$21.97 million, approximately ₹208 crore, for the manufacture and supply of 40,000 M107 artillery shell bodies to a North American customer. The programme marked its expansion into precision manufacturing of complete artillery shell bodies, requiring specialised metallurgical and engineering capabilities.

The company subsequently announced a significantly larger US$104.9 million contract in July 2026 for next-generation extended-range 155mm base-bleed artillery shell bodies. This programme expanded its participation in more advanced artillery ammunition manufacturing.

In October, Sigma signed an exclusive Memorandum of Understanding with Munitions India Limited for cooperation in the indigenous integration, manufacture and supply of 155mm course-correction fuzes and associated technologies.

The latest US$19.7 million export order adds specialised ancillary subsystems to this growing portfolio. Together, these developments demonstrate Sigma’s progression across multiple segments of the artillery ammunition manufacturing industry.

From Shell Bodies and Fuzes to Integrated Ammunition Manufacturing

Sigma Advanced Systems is expanding its industrial capabilities to address more complex requirements in artillery ammunition manufacturing.

The production of artillery shell bodies requires precision engineering, controlled manufacturing processes and specialised metallurgical expertise. Fuze technologies introduce additional requirements involving sophisticated mechanical and electronic components, reliability and integration with ammunition systems.

Ancillary subsystems further broaden the engineering and manufacturing activities involved in producing artillery ammunition.

By developing capabilities across these complementary areas, Sigma aims to strengthen its position as an integrated manufacturing and engineering partner rather than concentrating exclusively on individual components.

The company’s expanding portfolio also creates opportunities to undertake programmes involving different stages of ammunition manufacturing, supporting greater participation in international defence production networks.

Sigma and Munitions India Collaborate on Indigenous Course-Correction Fuzes

The latest export order follows Sigma’s October 14, 2026, announcement of an exclusive collaboration with Munitions India Limited, a Defence Public Sector Undertaking under the Ministry of Defence.

The Memorandum of Understanding establishes cooperation for the integration, indigenous manufacturing and supply of course-correction fuzes for 155mm artillery ammunition, along with associated subsystems and technologies.

Course-correction fuzes represent an important technological development in artillery ammunition because they are designed to support trajectory adjustments that can improve the accuracy of compatible artillery projectiles.

The partnership combines Sigma’s expanding expertise in ammunition technologies with the industrial capabilities of Munitions India Limited. It supports domestic manufacturing of specialised artillery components and contributes to India’s efforts to strengthen indigenous defence production.

The October 21 export order represents a separate commercial development. While the Munitions India agreement focuses on technological collaboration and indigenous production, the new contract involves the manufacture and supply of specialised ancillary subsystems to an overseas customer.

Together, the two initiatives highlight Sigma’s simultaneous expansion in domestic defence technology partnerships and international ammunition manufacturing.

Indian Defence Manufacturing Expands Its Role in Global Supply Chains

The growing international demand for artillery ammunition has increased the importance of reliable manufacturing capacity and specialised component suppliers.

Modern artillery ammunition production involves multiple industrial processes, including precision engineering, metallurgy, component manufacturing, quality assurance and systems integration. These requirements create opportunities for companies capable of producing specialised components to demanding technical standards.

Indian defence manufacturers have been expanding their participation in international markets through investments in advanced manufacturing, indigenous technology development and partnerships with overseas defence companies.

Sigma’s latest order reflects this broader industrial development. By securing contracts across several categories of 155mm ammunition components, the company is establishing a wider presence within international defence manufacturing supply chains.

The participation of Indian enterprises in such programmes also supports the development of domestic industrial expertise and strengthens the country’s aerospace and defence manufacturing ecosystem.

Sigma CEO Highlights Growing Demand for Engineering Capabilities

Commenting on the export order, Sunil Kalidindi, Chief Executive Officer of Sigma Advanced Systems Limited, highlighted the increasing emphasis international defence customers place on engineering depth, manufacturing consistency and the ability to supply specialised products at scale.

He explained that global defence customers are increasingly seeking industrial partners capable of supporting complex manufacturing requirements across the ammunition supply chain rather than supplying only individual components.

According to Kalidindi, the latest order builds upon Sigma’s existing capabilities in the 155mm segment and represents another step towards expanding its role in international defence manufacturing.

The company’s strategy focuses on developing the technical and manufacturing capabilities required to participate in increasingly sophisticated ammunition programmes while strengthening relationships with international customers.

The new contract provides another opportunity for Sigma to demonstrate its manufacturing capabilities and expand its contribution to the international artillery ammunition industry.

Make in India Defence Exports Gain Another Manufacturing Milestone

Sigma Advanced Systems’ ₹174 crore export order highlights the growing participation of Indian private-sector companies in specialised defence manufacturing.

The company’s successive contracts for filled fuzes, M107 shell bodies, extended-range base-bleed shell bodies and ancillary subsystems demonstrate how domestic enterprises are expanding their capabilities across different segments of ammunition production.

Its collaboration with Munitions India Limited further strengthens the connection between indigenous technology development and industrial manufacturing.

The latest export order also reflects the increasing opportunities available to Indian companies capable of meeting international defence manufacturing requirements.

By expanding precision engineering capabilities, strengthening domestic production networks and building long-term relationships with overseas customers, Sigma is contributing to the development of India’s defence manufacturing industry.

The company’s fifth 155mm ammunition engagement within six months marks another step in its progression towards integrated ammunition engineering and manufacturing. It also reinforces India’s expanding presence in international defence supply chains and supports the broader objectives of Make in India and Aatmanirbhar Bharat.
