Who Are We?

Steadfast Defence & Infra Private Limited, incorporated in 2019, is an Indian defence and infrastructure manufacturer operating from Kolkata, West Bengal. The company is first and foremost a licensed manufacturer of small arms and ammunition, and has since extended that engineering base into anti-drone systems — including interceptor drones — alongside a growing range of unmanned aerial platforms for the armed forces, central armed police organisations and approved export customers.

A fourth line, AI in Defence, applies the same engineering discipline to software: RAG-based cognitive assistants, on-premises soldier language models and air-gapped decision support that run entirely inside the customer’s own network, with no data leaving Indian soil. Explore the AI in Defence line.

Arms and ammunition manufacture is carried out under Ministry of Home Affairs Licence No. M/New/0157/MHA/2023 (UIN 10670MANF528192023), from a dedicated production facility at Narendrapur, South 24 Parganas. Our Kolkata operations draw on the established ordnance vendor ecosystem around Rifle Factory Ishapore, deep-water port access and engineering talent from IIT Kharagpur — a combination that supports rapid prototyping, qualification testing and volume production under a single roof.
